Year-Round Nepal Trekking: The Complete 12-Month Guide

The question every aspiring Nepal trekker asks is deceptively simple: "When should I go?" The answer, however, is anything but straightforward. Nepal's dramatic topography creates microclimates that vary wildly by region, elevation, and exposure. A month that delivers perfect conditions in one valley might bring impassable trails in another. Understanding this complexity transforms a good trek into an extraordinary one.

This comprehensive guide breaks down every month of the year, providing the detailed intelligence you need to choose your optimal timing. We examine weather patterns, crowd dynamics, cost fluctuations, trail conditions, festival impacts, and region-specific considerations. Whether you are a budget-conscious adventurer seeking off-season solitude, a photographer chasing perfect visibility, or a first-timer wanting maximum reliability, this guide provides the data-driven insights to inform your decision.

The truth is there is no universally "best" time to trek Nepal. October delivers the most reliable conditions, but with maximum crowds and premium prices. January offers solitude and crystal-clear skies, but bone-chilling cold. July brings lush landscapes and empty trails, but monsoon rains and leeches. Each month presents a unique equation of tradeoffs that align differently with individual priorities.

Understanding Nepal's Four Seasons

Before diving into monthly details, understanding Nepal's seasonal framework provides essential context. The country experiences four distinct seasons, each shaped by the South Asian monsoon cycle and Himalayan geography.

Pre-Monsoon / Spring (March-May)

Spring marks the transition from dry winter to wet monsoon. Temperatures warm steadily, rhododendrons bloom spectacularly across middle elevations, and trekking conditions are generally excellent through April. May sees increasing pre-monsoon instability with afternoon thunderstorms becoming common. This season offers Nepal's second-best trekking window, rivaling autumn for many trekkers who prefer warmer temperatures and flowering landscapes.

Monsoon / Summer (June-September)

The Southwest Monsoon dominates June through September, bringing 70-80% of Nepal's annual precipitation. Heavy afternoon rains, persistent clouds, trail damage, and active leeches make most trekking regions challenging. However, rain shadow regions north of the Himalayan divide (Upper Mustang, Dolpo, parts of Manang) receive minimal monsoon precipitation, making them paradoxically excellent during this period. Late September marks the monsoon's retreat and improving conditions.

Post-Monsoon / Autumn (October-November)

Autumn is Nepal's premier trekking season. The monsoon's departure leaves exceptionally clean air with visibility exceeding 100 kilometers. Stable high-pressure systems bring minimal precipitation, moderate temperatures, and the most reliable weather windows of the year. This is when most trekkers visit, creating high demand but also full infrastructure operation. Late November transitions toward winter with colder temperatures and potential high-altitude snow.

Winter (December-February)

Winter brings cold, dry conditions with crystal-clear visibility rivaling autumn. Temperatures drop significantly, particularly at high elevations where nights can reach -20C to -30C. Crowds thin dramatically, prices drop, and trails offer solitude. Many high-altitude lodges close, high passes may become impassable with snow, and shorter daylight hours limit trekking windows. For properly equipped trekkers, winter offers exceptional value and experience on appropriate routes.


Quick Reference: 12-Month Calendar


January: Deep Winter Clarity

Season Rating: 6/10 | Weather: Cold and clear | Crowds: Very Low | Cost: Budget

January stands as Nepal's coldest month and the nadir of trekking traffic. Most international trekkers have returned home after the autumn rush, leaving trails remarkably peaceful. For those prepared for genuine Himalayan winter, January offers exceptional conditions at a fraction of peak-season costs.

Weather Conditions

January's weather pattern is defined by cold, stable high-pressure systems that bring clear skies and minimal precipitation. Rainfall averages just 15-25mm across major trekking regions, making it one of the driest months of the year.

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 2C to 19C
  • Mid-elevations (3,000-3,500m): -8C to 10C
  • High elevations (4,500-5,000m): -18C to 2C
  • Extreme altitudes (5,500m+): -25C to -5C

The dramatic diurnal temperature swing characterizes January trekking. Mornings start bitterly cold, often with frost coating everything at mid-elevations and above. By midday, direct sun brings welcome warmth. Afternoons remain pleasant until the sun drops behind ridges, triggering rapid temperature decline.

Trail Conditions

Lower-elevation trails (below 3,500m) remain in excellent condition with minimal snow impact. The dry winter air keeps paths dust-free without monsoon mud. Higher trails may have patchy snow and ice, particularly on north-facing slopes and shaded sections.

High passes above 5,000m face variable conditions. Thorong La, Larkya La, and the Everest Three Passes may have significant snow accumulation requiring trail-breaking or making crossing dangerous. Conditions change year-to-year, making flexibility essential for high-altitude routes.

Crowd Levels

January sees 60-70% fewer trekkers than October peak. Popular teahouses that accommodate 40-50 guests in autumn might host 8-10 in January. Many lodges close entirely at high elevations, but those remaining open provide personalized attention impossible during busy months.

Lodge Closures in January

Many high-altitude lodges close in January, particularly above 4,500m on routes like Everest Base Camp and Annapurna Circuit. Teahouses at Gorak Shep, Thorong High Camp, and similar locations may operate with skeleton staff or close entirely. Contact lodges in advance or travel with an agency that confirms availability.

Best Treks for January

Highly Recommended:

  • Poon Hill Trek (max 3,210m) - All lodges open, spectacular winter views
  • Mardi Himal Trek (max 4,500m) - Lower than ABC, manageable cold
  • Lower Langtang Valley to Kyanjin Gompa (3,870m) - Stunning snow scenery
  • Helambu Circuit (max 3,650m) - Close to Kathmandu, mild conditions
  • Kathmandu Valley Rim (2,000-2,800m) - Day treks with mountain views

Possible with Proper Gear:

  • Everest Base Camp - Very cold but doable; some lodges remain open
  • Gokyo Lakes - Similar to EBC; requires cold tolerance
  • Lower Annapurna Circuit (skipping Thorong La) - Valley sections accessible

Best Avoided:

  • Annapurna Circuit full crossing - Thorong La often impassable
  • Manaslu Circuit - Larkya La frequently snow-blocked
  • Three Passes Trek - Too cold and snowy for most trekkers
  • Upper Dolpo - Extreme conditions, lodges closed
  • Kanchenjunga - Remote and severely cold

Special Events/Festivals

  • Maghe Sankranti (mid-January): Festival marking longer days, ritual bathing
  • Sonam Losar (late January/early February): Tamang New Year celebrations
  • Limited festival impact on trekking logistics during January

Cost Considerations

January offers Nepal's lowest trekking costs. Expect:

  • Teahouse prices: 20-40% below peak season
  • Guide/porter daily rates: $20-30/day vs $30-45 peak
  • Package tour discounts: 25-40% off autumn rates
  • Flight deals: Kathmandu flights often discounted
  • Permit costs: Standard fees (no seasonal variation)
💡

January Strategy

Target lower-elevation treks that maximize January's advantages (clear skies, solitude, budget prices) while avoiding its challenges (extreme cold at high altitude). The Poon Hill and Mardi Himal treks offer excellent January conditions with full infrastructure. If attempting higher routes, bring gear rated for -25C and build flexibility into your itinerary.


February: Late Winter Warming

Season Rating: 7/10 | Weather: Cold but moderating | Crowds: Low | Cost: Budget to Mid-range

February marks the slow transition from deep winter toward spring. Early February resembles January with significant cold, but the second half brings noticeable warming, lengthening days, and the first hints of spring. This underrated month offers many of winter's advantages with moderating temperatures that make trekking more comfortable than January.

Weather Conditions

February's weather improves progressively through the month. Early February (1st-15th) maintains winter patterns with cold nights and clear days. Late February (15th-28th) sees temperatures rise 3-5C, reducing the intensity of cold at high elevations.

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 4C to 21C
  • Mid-elevations (3,000-3,500m): -5C to 12C
  • High elevations (4,500-5,000m): -15C to 4C
  • Extreme altitudes (5,500m+): -22C to -3C

Precipitation remains minimal (20-30mm monthly average), maintaining the dry conditions that characterize Nepal's winter. Visibility rivals October at its best, with crystal-clear air providing exceptional mountain photography conditions.

Trail Conditions

Lower trails remain excellent throughout February. By late month, some high passes begin clearing as temperatures moderate, though conditions vary significantly year-to-year. Snow from winter accumulation persists on north-facing slopes and in shaded gullies at high elevations.

High passes (Thorong La, Larkya La) remain challenging in early February but may become crossable by late month in good years. Monitoring current conditions becomes critical for pass-crossing plans.

Crowd Levels

February sees increasing trekker numbers compared to January, particularly in the second half as conditions improve. Expect 40-50% fewer trekkers than October peak. The gradual crowd increase brings reopening of some seasonally-closed lodges, improving infrastructure availability.

Best Treks for February

Excellent Conditions:

  • All lower-elevation treks (Poon Hill, Helambu, Kathmandu Valley)
  • Langtang Valley - Warming temperatures make high point (Tserko Ri) more accessible
  • Mardi Himal - Excellent late February conditions
  • Everest View Trek - Lower-altitude Everest region option
  • Pikey Peak - Uncrowded viewpoint with EBC panorama

Good Conditions (Late February):

  • Everest Base Camp - Improving conditions, some lodges reopening
  • Gokyo Lakes - Crystal-clear lake reflections in still winter air
  • Annapurna Base Camp - Warming but still cold at base camp

Challenging:

  • Annapurna Circuit (Thorong La) - Possible late month, weather-dependent
  • Manaslu Circuit - Larkya La may be clearing
  • Three Passes - Still demanding cold and snow

Special Events/Festivals

  • Losar (Tibetan New Year): Celebrated in Himalayan Buddhist communities, typically late February. Monasteries hold special prayers, colorful ceremonies occur in Sherpa villages
  • Maha Shivaratri (late February/early March): Major Hindu festival at Pashupatinath Temple, Kathmandu
  • Democracy Day (February 18th): National holiday, minimal trekking impact

Cost Considerations

February pricing begins rising from January lows as spring approaches:

  • Early February: Similar to January (budget pricing)
  • Late February: 10-20% increase as demand rises
  • Overall: Still 15-30% below peak season costs
  • Lodge availability improving as seasonal reopening begins
💡

February Sweet Spot

Late February (Feb 20-28) often represents an optimal value window: temperatures have moderated significantly from deep winter, crowds remain low, prices stay below spring levels, and high-altitude lodges begin reopening. This window captures winter benefits without peak winter severity.


March: Spring Awakening

Season Rating: 8.5/10 | Weather: Warming, stable, excellent | Crowds: Moderate to High | Cost: Mid-range to Premium

March signals spring's arrival in the Himalayas. Temperatures warm noticeably, the first rhododendron blooms appear at lower elevations, and trekking conditions approach optimal levels. The month marks the beginning of Nepal's second peak trekking season, with crowds building through the month but not yet reaching April's intensity.

Weather Conditions

March brings the year's most comfortable temperature progression for many trekkers. Early March (1st-15th) retains late-winter coolness, particularly at high elevations. Late March (15th-31st) delivers genuinely pleasant temperatures across most trekking zones.

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 8C to 25C
  • Mid-elevations (3,000-3,500m): 0C to 15C
  • High elevations (4,500-5,000m): -10C to 8C
  • Extreme altitudes (5,500m+): -18C to 0C

Precipitation increases slightly from winter lows (30-50mm monthly) but remains minimal. Stable high-pressure patterns dominate, bringing mostly clear skies with occasional afternoon clouds. Visibility remains excellent, approaching autumn quality.

Trail Conditions

Trail conditions reach excellent status by mid-March. Winter snow has melted from all but the highest passes and north-facing pockets. High passes (Thorong La, Larkya La, Three Passes) become reliably crossable, though early March may see lingering snow.

The ground firms up without spring melt creating mud issues common in some mountain ranges. Trails are generally dry, well-defined, and easy to follow.

Crowd Levels

March sees the spring rush begin. Early March resembles late February with moderate crowds. By late March, popular routes like Everest Base Camp and Annapurna Circuit reach 60-70% of October peak levels. Advance booking becomes advisable for popular teahouses, though walk-up availability usually remains possible.

Rhododendron Bloom Timing

Rhododendron blooms progress upward with elevation through March and April. At 2,000-2,500m, expect early blooms in late March. At 2,500-3,000m, peak bloom occurs late March through early April. At 3,000-3,500m, blooms peak in mid-April. March trekkers catch the beginning of this spectacular natural display.

Best Treks for March

Exceptional Conditions:

  • Annapurna Base Camp - Early rhododendrons, excellent temperatures
  • Ghorepani Poon Hill - Blooming forests, spectacular sunrise views
  • Mardi Himal - Flowers and views combine beautifully
  • Langtang Valley - Comfortable temps, early wildflowers
  • Helambu - Full bloom at lower elevations

Excellent Conditions:

  • Everest Base Camp - Warmer than winter, excellent visibility
  • Annapurna Circuit - All passes open, pleasant temperatures
  • Manaslu Circuit - Larkya La in good condition
  • Gokyo Lakes - Lake ice clearing, stunning reflections
  • Three Passes - Demanding but optimal conditions

Also Recommended:

  • Upper Mustang - Pre-monsoon clarity, comfortable temperatures
  • Kanchenjunga Base Camp - Accessible for experienced trekkers
  • Makalu Base Camp - Remote but in season

Special Events/Festivals

  • Holi (March): Festival of colors, typically mid-March. Colorful powder celebrations in cities; limited impact on high-country trekking
  • Ghode Jatra (March): Horse racing festival in Kathmandu
  • Women's Day (March 8th): Growing celebration in Nepal

Cost Considerations

March pricing reflects the spring season buildup:

  • Early March: 10-20% below peak (late winter carryover)
  • Late March: Near peak-season pricing for popular routes
  • Guide/porter rates: Increasing toward peak levels ($25-35/day)
  • Flights: Kathmandu bookings filling for popular dates
💡

March Timing Strategy

Early March (1st-15th) offers the best value proposition: winter pricing lingers, crowds remain moderate, yet conditions have improved significantly from February. If rhododendron blooms are a priority, late March to early April is preferable for peak displays in the Annapurna region.


April: Peak Spring Season

Season Rating: 9/10 | Weather: Warm, excellent visibility, occasional afternoon haze | Crowds: High | Cost: Premium

April stands as spring's finest month, roughly equivalent to October in overall trekking quality. Rhododendron forests explode in full bloom, temperatures reach comfortable levels at all elevations, high passes are clear of snow, and the full trekking infrastructure operates at capacity. This is the month that draws trekkers seeking Nepal's famous floral displays alongside stunning mountain panoramas.

Weather Conditions

April offers Nepal's warmest pre-monsoon trekking with excellent stability through most of the month. Late April sees the first hints of monsoon influence with occasional afternoon thunderstorms and increasing haze.

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 13C to 28C
  • Mid-elevations (3,000-3,500m): 4C to 18C
  • High elevations (4,500-5,000m): -6C to 10C
  • Extreme altitudes (5,500m+): -12C to 3C

Precipitation remains low through mid-April (40-60mm monthly), increasing slightly late month. Morning skies are typically clear, with afternoon clouds building more frequently as April progresses. Visibility remains good to excellent, though late afternoon haze becomes noticeable, particularly in the Annapurna region.

Trail Conditions

Trail conditions reach peak excellence in April. All high passes are clear and crossable. Lower trails dry out completely. The combination of stable weather and open routes provides maximum flexibility for all trekking objectives.

The one consideration: some high-altitude routes (above 5,000m) see late-afternoon snow flurries as pre-monsoon instability increases. These rarely impact trail conditions but can create beautiful photography conditions.

Crowd Levels

April rivals October for crowd intensity on popular routes. Expect:

  • Everest Base Camp: 70-80% of October peak levels
  • Annapurna Base Camp: Very crowded (popular spring destination)
  • Poon Hill: Extremely busy (short trek, rhododendron season)
  • Manaslu Circuit: 50-60% of peak (permit limitations help)
  • Langtang: 60-70% of peak (easier access draws crowds)

Advance booking is essential for popular lodges, particularly in the Annapurna region during peak bloom weeks.

Best Treks for April

Exceptional (Rhododendron Focused):

  • Annapurna Base Camp - Peak bloom, the definitive spring ABC experience
  • Ghorepani Poon Hill - Maximum flower displays
  • Mardi Himal - Excellent blooms with fewer crowds than ABC
  • Langtang Valley - Beautiful flowering forests
  • Helambu - Lower elevation, early blooms already peaked

Excellent Conditions:

  • Everest Base Camp - Good temperatures, less haze than Annapurna
  • Annapurna Circuit - All sections accessible, blooms on southern approaches
  • Manaslu Circuit - Excellent timing for Larkya La
  • Three Passes - Demanding but ideal conditions
  • Gokyo Lakes - Lake views spectacular with spring clarity

Also Recommended:

  • Upper Mustang - Pre-monsoon stability, cultural richness
  • Kanchenjunga Base Camp - Optimal weather window
  • Makalu Base Camp - Wildflower season begins
  • Dolpo - Accessible before monsoon

Special Events/Festivals

  • Ram Navami (April): Celebrates Lord Ram's birthday
  • Bisket Jatra (mid-April): Nepali New Year in Bhaktapur, major cultural event
  • Buddha Jayanti (April/May): Buddha's birthday at Lumbini and Boudhanath

Cost Considerations

April commands premium pricing across all services:

  • Teahouse rates: Peak season pricing
  • Guide/porter rates: $30-45/day (peak demand)
  • Package tours: Full premium pricing
  • Flights: Book Lukla flights 3-4 months ahead
  • Annapurna region lodges: Advance booking essential during bloom weeks
💡

April Bloom Strategy

For maximum rhododendron viewing, target the Annapurna region in early to mid-April (April 1-20). Trek routes that pass through the 2,500-3,500m elevation band where blooms peak during this window. The Ghorepani-Ghandruk loop and ABC via Ghandruk route offer the most spectacular floral displays. The Everest region has fewer rhododendrons due to its drier, higher terrain.


May: Pre-Monsoon Transition

Season Rating: 7/10 | Weather: Warm to hot, afternoon instability | Crowds: Moderate | Cost: Mid-range

May occupies an interesting niche in Nepal's trekking calendar. It is the warmest comfortable trekking month, making high-altitude nights more bearable than any other time. However, increasing pre-monsoon instability brings afternoon clouds, haze, and occasional thunderstorms that compromise the crystal clarity of earlier months. For trekkers who prioritize warmth and don't require pristine visibility, May offers good value with moderate crowds.

Weather Conditions

May's weather pattern shows clear monsoon precursors. Mornings typically start clear, but clouds build through the day, often bringing afternoon showers by late May. The month divides distinctly:

Early May (1-15): Generally stable, similar to late April. Afternoon haze present but manageable. Occasional thunderstorms.

Late May (16-31): Monsoon precursors intensify. Daily afternoon clouds, more frequent thunderstorms, increasing humidity. Some trekkers encounter multi-day unsettled periods.

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 17C to 30C (can feel hot)
  • Mid-elevations (3,000-3,500m): 8C to 20C
  • High elevations (4,500-5,000m): -2C to 12C
  • Extreme altitudes (5,500m+): -8C to 5C

Precipitation increases significantly (80-150mm monthly), primarily from afternoon thunderstorms rather than prolonged rain.

Trail Conditions

Trail conditions remain good in early May but deteriorate through late May as thunderstorms increase. Lower trails (below 3,000m) may see mud developing. High passes remain accessible but require monitoring afternoon weather for safe crossing.

The increased instability makes flexible itineraries more important. Building in buffer days allows waiting out poor weather without schedule stress.

Crowd Levels

May sees moderate crowds, dropping significantly from April's peak:

  • Early May: 50-60% of April levels
  • Late May: 30-40% of peak as monsoon approaches
  • By late May, many trekkers have departed, leaving trails relatively peaceful

This crowd reduction means easier lodge availability, less competition for Lukla flights, and more personal teahouse experiences.

Best Treks for May

Good Conditions (Especially Early May):

  • Everest Base Camp - Warm temperatures at high camps, good visibility early month
  • Upper Mustang - Rain shadow protection from building monsoon
  • Annapurna Circuit - Thorong La accessible, warm crossing conditions
  • Manaslu Circuit - Larkya La warm and clear early May
  • Three Passes - Warmest conditions of any trekking month

Acceptable with Flexibility:

  • Gokyo Lakes - Warm but increasing afternoon clouds
  • Langtang Valley - Pleasant temperatures, some afternoon rain possible
  • Annapurna Base Camp - Warm but hazy, afternoon clouds at ABC

Transitioning to Monsoon (Late May):

  • Lower-elevation treks see increasing rain
  • Leeches begin activating below 3,000m
  • Flexibility essential; expect some weather delays

Treks to Avoid in May

  • Short treks with inflexible schedules (weather delays likely)
  • Routes entirely below 3,000m (heat, emerging leeches, rain)
  • Photography-focused treks (visibility compromised)

Special Events/Festivals

  • Buddha Jayanti (May full moon): Buddha's birthday celebration at Buddhist sites
  • Republic Day (May 28): National holiday
  • Monsoon preparation visible in villages

Cost Considerations

May offers good value as spring demand wanes:

  • Early May: 10-20% below peak spring rates
  • Late May: 20-35% below peak as monsoon approaches
  • Last-minute availability often possible
  • Guide/porter rates: $22-32/day
  • Some agencies offer monsoon-preview discounts
💡

May Strategy

Early May (May 1-15) offers warm trekking conditions with still-acceptable visibility. If you prioritize comfortable sleeping temperatures at high altitude over crystal-clear views, early May is an excellent choice. Book the Everest region over Annapurna for better late-season visibility, as the Khumbu generally has less haze than the Annapurna region.


June: Monsoon Arrival

Season Rating: 4/10 (standard routes) | 7/10 (rain shadow regions) | Weather: Monsoon rains, cloud cover | Crowds: Very Low | Cost: Budget

June marks the monsoon's definitive arrival. The Southwest Monsoon sweeps across Nepal, bringing daily rains, persistent clouds, and challenging trail conditions to most trekking regions. For standard routes, June is genuinely difficult. However, rain shadow regions north of the Himalayan divide experience minimal monsoon impact, creating a paradox: some of Nepal's best summer trekking exists during what is technically "off-season."

Weather Conditions

The monsoon transforms Nepal's weather pattern completely:

Typical June Pattern:

  • Mornings: Often clear or partly cloudy
  • Late morning to afternoon: Clouds build rapidly
  • Afternoon/evening: Rain, often heavy, lasting 2-6 hours
  • Night: Rain diminishes, cycle repeats

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 20C to 29C (humid heat)
  • Mid-elevations (3,000-3,500m): 10C to 18C (mild with rain)
  • High elevations (4,500-5,000m): 2C to 12C (cool, wet)
  • Rain shadow areas: Similar temps but dry

Precipitation reaches 250-450mm monthly in exposed regions, with some areas receiving over 500mm. Rain shadow regions (Upper Mustang, Dolpo, upper Manang) receive only 30-60mm.

Trail Conditions

Standard Trekking Regions:

  • Trails become muddy, slippery, and difficult
  • Streams swell; some river crossings become dangerous
  • Landslides periodically block trails
  • Leeches extremely active below 3,000m (especially Annapurna region)
  • Views obscured by persistent clouds

Rain Shadow Regions:

  • Trails remain dry and excellent
  • Minimal precipitation impact
  • Clear mornings common
  • Afternoon clouds may roll in but rarely bring significant rain

Rain Shadow Phenomenon

The high Himalayan divide blocks most monsoon moisture from reaching valleys north of the main range. Upper Mustang, Dolpo, and parts of upper Manang lie in this "rain shadow," receiving less than 20% of the precipitation that drenches southern slopes. This creates trekking opportunities during months when standard routes are impractical.

Crowd Levels

June sees 70-80% fewer trekkers than October. Even rain shadow regions, which offer good conditions, attract minimal visitors. This creates exceptional solitude but also means some infrastructure operates at minimum capacity.

Best Treks for June

Excellent (Rain Shadow):

  • Upper Mustang - Dry, clear, culturally fascinating
  • Dolpo (Lower and Upper) - Pristine remoteness, minimal monsoon
  • Nar-Phu Valley - North of Annapurna, rain shadow protected
  • Upper Manang (Tilicho Lake) - Less rain than southern Annapurna approaches

Possible with Acceptance of Conditions:

  • High-altitude routes above 4,000m (less leech activity, above worst rain)
  • Langtang (upper valley) - Moderate rain shadow benefit
  • Early morning hikes returning before afternoon rain

Best Avoided:

  • Everest Base Camp - Clouds, rain, flight cancellations
  • Annapurna Base Camp - Very wet, heavy leech activity
  • Annapurna Circuit (southern sections) - Extreme rain and leeches
  • Poon Hill - Soaked trails, minimal views
  • Any route below 3,000m in southern regions

Special Events/Festivals

  • Saga Dawa (June): Buddhist festival celebrating Buddha's enlightenment
  • Rice planting season begins in lower valleys
  • Villages quiet as agricultural work intensifies

Cost Considerations

June offers rock-bottom pricing:

  • Teahouse rates: 30-50% below peak
  • Guide/porter rates: $15-25/day (low demand)
  • Package tours: Major discounts for rain shadow treks
  • Permits: Standard pricing (no seasonal variation)
  • Upper Mustang restricted permit: Still expensive but fewer crowds mean better experience
💡

June Rain Shadow Strategy

If you can only trek in June, commit fully to a rain shadow route. Upper Mustang offers the most accessible option with established infrastructure. Plan 10-14 days to fully explore while conditions remain excellent. Book with an agency experienced in monsoon-season operations who understands local conditions.


July: Peak Monsoon

Season Rating: 3/10 (standard routes) | 6.5/10 (rain shadow regions) | Weather: Heavy monsoon rains | Crowds: Lowest of year | Cost: Lowest of year

July represents the monsoon's peak intensity. Rainfall reaches annual maximums, clouds envelop the mountains for days at a time, and standard trekking routes present genuine challenges. This is Nepal's true off-season, when the country's famous peaks often remain invisible for weeks. Yet for determined trekkers willing to embrace monsoon conditions or focus on rain shadow regions, July offers unmatched solitude and budget pricing.

Weather Conditions

July's monsoon reaches full intensity:

Typical Pattern:

  • Brief clear windows: Usually early morning (5-9am)
  • Cloud buildup: Rapid after 9am
  • Afternoon rain: Almost guaranteed, often heavy
  • Precipitation: 350-600mm monthly in exposed areas
  • Humidity: High, making even moderate temperatures feel oppressive at lower elevations

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 22C to 29C (very humid)
  • Mid-elevations (3,000-3,500m): 12C to 18C
  • High elevations (4,500-5,000m): 4C to 12C
  • Rain shadow areas: 8C to 22C depending on elevation

Rain shadow regions receive 40-80mm monthly, roughly 10-15% of exposed areas.

Trail Conditions

Exposed Regions:

  • Trails become waterlogged and extremely muddy
  • River crossings may be impassable
  • Landslide risk at maximum
  • Leeches reach peak populations (thousands per kilometer on some trails)
  • Visibility often limited to immediate surroundings
  • Some trails close due to damage

Rain Shadow Regions:

  • Trails remain passable though not pristine
  • Occasional afternoon showers possible
  • Dry streambeds may have seasonal water
  • Some high passes can see snow even in July
  • Generally good trekking conditions

Crowd Levels

July sees the year's lowest trekker numbers:

  • 80-85% reduction from October peak
  • Some teahouses close entirely
  • Rain shadow routes have trails nearly to yourself
  • Lodge owners surprised and welcoming
  • Authentic cultural interactions more likely

Best Treks for July

Viable (Rain Shadow):

  • Upper Mustang - Premier monsoon-season destination
  • Dolpo - For experienced trekkers seeking remoteness
  • Nar-Phu Valley - Challenging but rewarding

Very Challenging (For Experienced Monsoon Trekkers Only):

  • High Everest region (above 4,000m) - Fewer leeches, but cloud/rain issues
  • Upper Langtang - Some rain shadow benefit
  • Tsum Valley - Moderate protection from monsoon

Do Not Attempt:

  • All standard Annapurna routes - Severe conditions
  • Everest Base Camp (standard route) - Flight cancellations, poor conditions
  • Poon Hill, ABC, Annapurna Circuit southern sections
  • Any low-elevation forest trekking - Leech nightmare

Treks to Avoid

Essentially all trekking outside rain shadow regions should be avoided in July. The combination of rain, leeches, poor visibility, and infrastructure challenges makes standard routes inadvisable.

Special Events/Festivals

  • Guru Purnima (July): Teachers' day in Hindu/Buddhist traditions
  • Rice planting in full swing
  • Monastery festivals in Mustang (inquire locally for dates)

Cost Considerations

July matches June for lowest annual pricing:

  • Maximum discounts on all services
  • Some agencies offer 40-60% off standard package rates for rain shadow treks
  • Domestic flights often discounted
  • Upper Mustang permits remain expensive but crowds minimal
  • Negotiate everything; demand is at annual low
💡

July Reality Check

July trekking requires either commitment to rain shadow regions or genuine acceptance of challenging monsoon conditions. If you are set on July travel, book Upper Mustang or Dolpo with a reputable agency. These treks offer genuine quality experiences when most of Nepal is too wet to enjoy.


August: Late Monsoon Challenges

Season Rating: 4/10 (standard routes) | 6.5/10 (rain shadow) | Weather: Continued heavy monsoon | Crowds: Very Low | Cost: Budget

August continues July's monsoon intensity with conditions remaining challenging across most of Nepal. The month offers little improvement over July for standard routes, though late August occasionally shows early signs of the monsoon's retreat. Rain shadow regions maintain their advantage, providing the only viable trekking options for most visitors.

Weather Conditions

August's weather closely mirrors July:

Typical Pattern:

  • Morning clarity: Brief windows (5-8am)
  • Rapid cloud development: 8-10am
  • Afternoon/evening rain: 2-8 hours daily
  • Precipitation: 300-550mm in exposed regions
  • Late August: First hints of monsoon weakening (variable by year)

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 22C to 29C
  • Mid-elevations (3,000-3,500m): 12C to 18C
  • High elevations (4,500-5,000m): 4C to 12C
  • Rain shadow areas: 10C to 22C

Rain shadow regions see 30-70mm monthly, maintaining their dry advantage.

Trail Conditions

Trail conditions remain similar to July:

  • Exposed routes: Extremely muddy, some closures
  • Landslide risk: Still high
  • Leeches: Peak populations continue
  • Rain shadow regions: Passable to good conditions
  • Late August: Very occasional improvement in exposed areas

Crowd Levels

August continues rock-bottom crowd levels:

  • Similar to July (80-85% below peak)
  • Slightly more trekkers late August anticipating September improvement
  • Rain shadow regions see marginally increased interest
  • Overall: Extreme solitude remains the norm

Best Treks for August

Recommended (Rain Shadow):

  • Upper Mustang - Continues as best monsoon option
  • Dolpo - Remote, challenging, rewarding
  • Nar-Phu Valley - For experienced trekkers

Possible Late August:

  • Upper Langtang - As monsoon begins retreating
  • High-elevation routes - Above worst leech zones

Avoid:

  • All standard routes below 4,000m in exposed regions
  • Annapurna region entirely (except Nar-Phu)
  • Standard Everest approach

Special Events/Festivals

  • Naga Panchami (August): Worship of serpent deities
  • Janai Purnima/Raksha Bandhan (August): Sacred thread festival
  • Gai Jatra (August): Festival honoring the deceased
  • Krishna Janmashtami (August): Krishna's birthday

These festivals occur primarily in Kathmandu Valley and do not significantly impact high-country trekking.

Cost Considerations

August maintains July's budget pricing:

  • Lowest rates continue
  • Some early-September bookings may see slight increases
  • Overall: Excellent value for rain shadow treks
  • Guide availability high; negotiate favorable rates
💡

Late August Timing

If you must trek in August, target late August (August 20-31) when the monsoon occasionally shows early weakening. Conditions remain challenging but you may catch improving weather that continues into early September. Monitor forecasts closely and maintain schedule flexibility.


September: Monsoon Retreat

Season Rating: 7/10 | Weather: Improving rapidly, variable | Crowds: Moderate | Cost: Mid-range

September marks the monsoon's retreat and Nepal's trekking renaissance. Early September (1-15) often resembles late monsoon with continued rain and clouds, but late September (15-30) sees dramatic improvement as stable post-monsoon conditions establish. This transitional month offers excellent value for trekkers willing to accept some uncertainty, with conditions that approach autumn quality by month's end.

Weather Conditions

September's weather divides clearly:

Early September (1-15):

  • Monsoon still active but weakening
  • Daily afternoon rain still common
  • Clouds frequently obscure views
  • Humidity remains high
  • Precipitation: 150-250mm for half-month

Late September (15-30):

  • Monsoon retreating rapidly
  • Clear mornings extend longer
  • Afternoon rain becomes occasional rather than daily
  • Visibility improves dramatically
  • Air clarity approaching autumn levels
  • Precipitation: 50-100mm for half-month

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 19C to 28C
  • Mid-elevations (3,000-3,500m): 8C to 17C
  • High elevations (4,500-5,000m): 0C to 10C
  • Extreme altitudes (5,500m+): -8C to 4C

Trail Conditions

Early September trails remain monsoon-affected:

  • Muddy sections common
  • Leeches still active (declining)
  • Some trail damage from monsoon rains

Late September sees rapid improvement:

  • Trails drying quickly
  • Leech activity declining sharply above 2,500m
  • High passes clearing and accessible
  • Infrastructure ramping up for autumn season

Crowd Levels

September crowds increase through the month:

  • Early September: 30-40% of October peak
  • Late September: 50-60% of October peak
  • Significant increase from August but still moderate
  • Good lodge availability; advance booking helpful but not essential

September Value Proposition

Late September (Sept 20-30) often delivers 80-90% of October's weather quality at 60-70% of October's prices and with half the crowds. For value-conscious trekkers with schedule flexibility, this window represents one of the year's best opportunities. Be prepared for occasional rain days and maintain itinerary flexibility.

Best Treks for September

Excellent (Late September):

  • Everest Base Camp - Improving conditions, moderate crowds
  • Annapurna Circuit - Thorong La accessible, fewer people than October
  • Manaslu Circuit - Good pass conditions, uncrowded
  • Langtang Valley - Beautiful transitional landscapes
  • Gokyo Lakes - Lakes at optimal levels after monsoon

Good (Entire Month):

  • Upper Mustang - Excellent throughout; transitioning from summer dry to autumn dry
  • Poon Hill - Conditions improving; early month wet, late month good
  • Mardi Himal - Accessible shorter option
  • Helambu - Lower elevations dry faster

Challenging (Early September Only):

  • Three Passes - Possible late month; risky early month
  • High-altitude routes generally improve dramatically after September 15

Special Events/Festivals

  • Indra Jatra (September): Major festival in Kathmandu Valley
  • Dashain preparation begins late September
  • Teej (September): Women's festival

Cost Considerations

September pricing reflects the transitional period:

  • Early September: Budget pricing (20-30% below peak)
  • Late September: Mid-range (10-20% below peak)
  • Guide/porter rates: $22-32/day
  • Lodge availability: Good; some advance booking advisable late month
  • Lukla flights: Increasing demand; book 2-4 weeks ahead
💡

September Strategy

Target September 20-30 for optimal value. By this window, monsoon has retreated sufficiently for excellent trekking while prices and crowds remain below October peaks. Build 1-2 buffer days into your itinerary for potential weather delays. If your schedule is inflexible, consider late September to early October (Sept 25 - Oct 10) as a sweet spot.


October: Peak Season Excellence

Season Rating: 10/10 | Weather: Perfect stability | Crowds: Very High | Cost: Premium

October stands as Nepal's undisputed premier trekking month. Post-monsoon air clarity delivers the year's best visibility, stable high-pressure systems bring minimal precipitation, temperatures remain comfortable at all elevations, and the entire trekking infrastructure operates at maximum capacity. This is when Nepal reveals its full Himalayan glory. The tradeoff: maximum crowds and premium pricing.

Weather Conditions

October's weather approaches perfection:

Typical Pattern:

  • Morning clarity: Exceptional (100+ km visibility)
  • Afternoon: Generally clear; occasional light clouds
  • Precipitation: 15-35mm monthly (one of the driest months)
  • Weather stability: Best of the year
  • Predictability: Very high; multi-day forecasts reliable

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 11C to 27C
  • Mid-elevations (3,000-3,500m): 3C to 16C
  • High elevations (4,500-5,000m): -5C to 10C
  • Extreme altitudes (5,500m+): -12C to 3C

The temperature range sits in a "Goldilocks zone": warm enough for comfortable daytime trekking, cool enough for quality sleep, not yet cold enough to require extreme winter gear.

Trail Conditions

Trail conditions reach annual peak:

  • Dry, firm, well-maintained trails
  • All high passes clear and accessible
  • No monsoon damage (repairs completed)
  • No ice/snow issues except at extreme altitudes
  • Perfect for all ability levels

Crowd Levels

October sees maximum trekking traffic:

  • 100% peak capacity on popular routes
  • Everest Base Camp: 500-800+ daily departures from Lukla
  • Annapurna Circuit and ABC: Very crowded
  • Teahouses on popular routes: Fully booked
  • Lukla flights: Oversubscribed; delays common

Advance booking becomes essential:

  • Lukla flights: 3-4 months ahead
  • Popular teahouses (Namche, Tengboche, Dingboche, Gorak Shep): 4-6 weeks ahead
  • Guided packages: 2-3 months ahead

Best Treks for October

Exceptional (All Routes at Peak):

  • Everest Base Camp - Iconic, perfect conditions, very crowded
  • Annapurna Circuit - All passes optimal, full lodge chain open
  • Annapurna Base Camp - Crystal clear amphitheater views
  • Manaslu Circuit - Excellent Larkya La crossing, fewer crowds than EBC
  • Gokyo Lakes - Stunning clarity, 30% fewer people than EBC
  • Three Passes - All passes in optimal condition
  • Langtang Valley - Easy access, excellent views

Also Excellent:

  • Poon Hill - Short trek, spectacular sunrise
  • Mardi Himal - Less crowded ABC alternative
  • Upper Mustang - Cooling from summer, dry and clear
  • Kanchenjunga - Optimal weather window
  • Makalu Base Camp - Clear approaches

Everything Works: Virtually any Nepal trek is viable in October. Route choice depends on your preferences, fitness, and time available rather than weather limitations.

Treks to Avoid (Crowd Reasons Only)

No treks should be avoided for weather reasons. Some trekkers avoid:

  • Poon Hill (extreme crowds for short trek)
  • Standard ABC route (consider Mardi Himal alternative)
  • First week of October (Dashain festival domestic tourism surge)

Special Events/Festivals

Dashain (Early-Mid October): Nepal's biggest festival (15 days). Domestic tourism surges as Nepali families travel to mountains. Some services reduce operations as staff return to home villages. International trekkers may find early October (Oct 1-15) more challenging.

Tihar (Late October): Festival of Lights (5 days). Beautiful celebrations in villages; less disruptive to trekking than Dashain.

Festival Timing Strategy

Dashain dates vary by lunar calendar but typically fall October 1-20. The optimal October window is often October 20-31, after Dashain concludes but while peak autumn conditions continue. This window offers slightly reduced crowds, full services resumed, and excellent weather.

Cost Considerations

October commands maximum pricing:

  • Teahouse rates: Peak season (20-40% above off-season)
  • Guide/porter rates: $30-45/day
  • Package tours: Premium pricing
  • Lukla flights: Premium plus availability challenges
  • Everything: Book early, budget for peak rates
💡

October Crowd Management

If trekking in October, embrace the social atmosphere or pursue less-crowded alternatives. Gokyo Lakes offers EBC-quality scenery with 30% fewer people. Manaslu Circuit has permit-limited crowds. Khopra Ridge and similar off-beaten routes provide solitude. If choosing popular routes, start trekking days very early (5:30am) to reach lodges before crowds and secure better room selection.


November: Late Autumn Excellence

Season Rating: 9/10 | Weather: Excellent but cooling | Crowds: High (declining) | Cost: Premium (declining late month)

November maintains October's excellent weather while crowds begin thinning noticeably. For trekkers who want peak-season conditions without peak crowds, November offers an appealing compromise. The catch: temperatures drop significantly, particularly at high elevations, requiring warmer gear than October. Late November transitions toward winter, with some high-altitude lodges beginning to close.

Weather Conditions

November continues autumn's dry, stable pattern with colder temperatures:

Typical Pattern:

  • Morning clarity: Exceptional (matches October)
  • Afternoon: Generally clear; occasional light clouds
  • Precipitation: 15-30mm monthly
  • Weather stability: Excellent
  • Temperature trend: Steadily cooling through month

Temperature Ranges by Elevation:

  • Kathmandu Valley (1,400m): 7C to 23C
  • Mid-elevations (3,000-3,500m): -2C to 14C
  • High elevations (4,500-5,000m): -12C to 6C
  • Extreme altitudes (5,500m+): -18C to -2C

Late November temperatures approach winter levels, particularly at high elevations. The temperature drop from October is significant: expect nights 5-10C colder than October at equivalent elevations.

Trail Conditions

Trail conditions remain excellent through mid-November:

  • Dry, firm trails continue
  • High passes accessible
  • No significant weather disruptions

Late November (Nov 20-30) sees transitional conditions:

  • Occasional high-altitude snow possible
  • Some passes may have light snow coverage
  • North-facing trails begin accumulating ice in shade
  • Most routes remain fully accessible

Crowd Levels

November crowds decline progressively:

  • Early November (Nov 1-10): 80-85% of October peak
  • Mid-November (Nov 10-20): 60-70% of October peak
  • Late November (Nov 20-30): 40-50% of October peak

This creates a gradually improving crowd situation while conditions remain excellent.

Best Treks for November

Excellent Throughout:

  • Everest Base Camp - Cold nights but spectacular conditions
  • Gokyo Lakes - Crystal clarity, thinning crowds
  • Annapurna Circuit - Thorong La accessible; bring warm gear
  • Manaslu Circuit - Larkya La still good; fewer crowds
  • Langtang Valley - Beautiful late autumn scenery
  • Mardi Himal - Comfortable altitude for cooling temps

Better Early November:

  • Three Passes - All passes accessible; get progressively colder
  • High-altitude routes above 5,000m
  • Routes with lodges that close late November

Good Late November:

  • Lower-elevation options (Poon Hill, Helambu)
  • Routes with reliable year-round lodges
  • Cultural treks with village stays

Special Events/Festivals

  • Tihar/Diwali (early November): Festival of Lights continues from late October
  • Chhath (November): Sun worship festival, particularly in Terai
  • Limited festival impact on high-country trekking

Cost Considerations

November pricing trends downward:

  • Early November: Peak pricing continues
  • Mid-November: 5-10% softening begins
  • Late November: 15-25% below early November
  • Guide/porter rates: $28-40/day (declining late month)
  • Some lodges offer late-season discounts
💡

November Sweet Spot

Mid-November (November 10-20) often represents optimal timing for those wanting excellent weather without October's intensity. Crowds have dropped 30-40% from peak, prices begin softening, yet weather remains superb and all infrastructure operates fully. Bring gear appropriate for colder nights than October (-15C sleeping bag recommended for high camps).


December: Early Winter Transition

Season Rating: 7/10 | Weather: Cold, clear, dry | Crowds: Low to Moderate | Cost: Mid-range (declining)

December marks the transition from autumn into winter. Early December (1-15) often retains excellent late-autumn conditions with manageable cold, while late December (16-31) sees genuine winter arrive with significant temperature drops and some high-altitude lodge closures. The month offers excellent value for cold-tolerant trekkers, combining good weather with reduced crowds and declining prices.

Weather Conditions

December's weather is cold but stable:

Typical Pattern:

  • Morning clarity: Excellent (winter dry air)
  • Afternoon: Generally clear
  • Precipitation: 15-25mm monthly
  • Temperature: Steadily dropping through month
  • Snow: Possible at high elevations, especially late month

  • Trails dry and excellent
  • High passes accessible (monitor conditions)
  • Similar to late November

Late December:

  • Snow at high elevations increasingly likely
  • Some passes may have accumulation
  • Ice possible on north-facing sections
  • Lower trails remain excellent

Crowd Levels

December crowds reach annual lows:

  • Early December: 30-40% of October peak
  • Mid-December: 25-35% of October peak
  • Christmas/New Year: Slight uptick from holiday travelers
  • Overall: Peaceful trails, personal teahouse experiences

Best Treks for December

  • Tamu Losar (late December): Gurung New Year

Cost Considerations

December offers excellent value:

  • Early December: 15-25% below peak season
  • Late December: 25-35% below peak
  • Guide/porter rates: $22-32/day
  • Holiday period may see slight price increase
  • Overall: Good balance of conditions and cost
💡

December Strategy

Early December (Dec 1-15) offers the best balance: autumn-like conditions with winter pricing. Target lower-elevation treks (Poon Hill, Mardi Himal, Langtang Valley) that maximize December's clear skies while minimizing extreme cold exposure. If attempting higher routes, confirm lodge availability in advance and bring gear rated for -20C nights.
