Best Seasons to Trek
What each season actually looks like on the trail - weather, temperatures, visibility, crowds, and exactly which routes suit which time of year.
Nepal Has Four Distinct Trekking Seasons
Nepal's climate is shaped by the Himalayas themselves and the seasonal monsoon cycle, giving the country four clearly defined trekking seasons rather than a single "best time" that applies everywhere. The right season for you depends on which route you're doing, how much cold you're comfortable with, and how much you value solitude on the trail over guaranteed mountain views.
If you only remember one thing: October and early November offer the most reliable combination of clear skies, comfortable temperatures, and open trails of any time in the Nepali calendar.
Season by Season
Autumn
September – NovemberPost-monsoon skies are washed clean and stay stable for weeks at a time, with crisp air, minimal rainfall, and consistently clear mountain views throughout the day.
- Best visibility of the year - mountain views are near-guaranteed
- Stable, predictable weather with very low rainfall
- Comfortable daytime trekking temperatures
- Trails and teahouses fully open, well-stocked, and well-staffed
- The busiest season - trails, teahouses, and flights can be crowded
- Higher demand means booking flights and rooms early matters more
Everest Base Camp, Annapurna Circuit, Annapurna Base Camp, Manaslu Circuit, and virtually every major route in Nepal
Spring
March – MayTemperatures climb steadily through the season as rhododendron forests bloom across mid-altitude trails. Skies are generally clear in the mornings, with a chance of afternoon haze or brief showers building toward late May.
- Warmer daytime temperatures than autumn, especially at lower altitudes
- Rhododendron and magnolia forests in full bloom on mid-altitude trails
- Prime season for 8,000m expedition climbing (Everest summit window falls here)
- Long daylight hours for trekking
- Increasing haze and dust by late spring can reduce distant mountain visibility
- Second-busiest season, with expedition traffic adding to Everest region crowds
Everest Base Camp, Annapurna Base Camp, Poon Hill (for the rhododendron bloom), and all major 8,000m expeditions
Winter
December – FebruarySkies are frequently at their clearest of the year, with dry, stable air and minimal precipitation - but daytime and especially nighttime temperatures drop significantly, and high passes can close after heavy snowfall.
- Exceptionally clear skies and long-distance mountain visibility
- Quiet trails and near-empty teahouses - the most solitary trekking experience
- Lower accommodation rates in most regions
- Genuinely cold, especially overnight at altitude - demands serious cold-weather gear
- High passes (Thorong La, Cho La, Renjo La) can close temporarily after snowfall
- Some higher teahouses close for the season in the coldest months
- Shorter daylight hours limit trekking windows
Everest Base Camp (lower/mid sections), Annapurna Base Camp, and short treks below 4,000m - high pass crossings carry real risk
Summer / Monsoon
June – AugustHeavy, sustained rainfall affects most of Nepal, bringing leeches on lower forested trails, frequent cloud cover obscuring mountain views, and landslide risk on some routes - but the trans-Himalayan rain-shadow regions stay largely dry.
- Lush, vividly green landscapes on lower-altitude trails
- Rain-shadow regions (Upper Mustang, Dolpo) remain dry and fully trekkable
- Very low trail traffic and the lowest accommodation rates of the year
- Frequent rain, cloud cover, and reduced mountain visibility on most standard routes
- Leeches are common on forested lower-altitude trails
- Landslide and trail-washout risk on some routes, plus flight delays are more frequent
Upper Mustang and Dolpo (rain-shadow regions) - most standard routes like EBC and Annapurna are not recommended this season
Month-by-Month Overview
A quick reference if you already have travel dates in mind and want to know what to expect.
A note on visibility
Even in the best months, mountain visibility is usually best in the early morning, before afternoon cloud build-up sets in - a pattern that holds throughout the year in the Himalayas. Guides typically plan the day's biggest viewpoints and passes for early morning for exactly this reason.
