When to Go
Nepal Trekking Seasons Explained
Nepal’s trekking calendar is divided into four distinct windows. Each brings different skies, temperatures, trail conditions, and crowd levels. Understanding the seasons is the first step to planning a trip you’ll love.
March – May
Spring (Peak)
Mild temperatures, rhododendron forests in bloom, and clear morning skies. One of the two main trekking windows.
June – August
Monsoon (Off-Peak)
Heavy rain closes main routes. Rain-shadow destinations like Upper Mustang and Nar Phu stay dry and are excellent this season.
September – November
Autumn (Best)
Crystal-clear skies, stable conditions, outstanding mountain views. October and November are the gold-standard months for trekking in Nepal.
December – February
Winter (Quiet)
Crisp, dust-free skies and very few trekkers. High passes above 5,000m are often snow-blocked, but lower routes are excellent and uncrowded.
Altitude & Weather Science
Why City Forecasts Are Useless Above 3,000m
A Kathmandu weather app is nearly meaningless on the Khumbu Glacier. Himalayan conditions are shaped by altitude lapse rates, wind-chill, valley microclimates, and the monsoon boundary — all of which this tool accounts for.
Temperature Lapse Rate
Temperature drops ~6.5°C per 1,000m of elevation gain. A 20°C day in Lukla (2,860m) equals roughly −5°C at Everest Base Camp (5,364m) — especially at night.
Wind-Chill Factor
At 0°C with 40 km/h gusts, the feels-like temperature drops to −10°C. Exposed ridges and high passes can be far colder than valley weather stations record.
Monsoon Rain Shadow
The Himalayas block Bay of Bengal moisture. Routes behind the main range — Upper Mustang, Nar Phu — remain dry and sunny even during peak monsoon months.
Climate Reference
Monthly Conditions at Altitude
Historical average conditions at key high-altitude stopping points across the main trekking seasons.
| Season / Months | Everest Zone (5,000m) | Annapurna Zone (4,000m) | Rain Risk | Trail Conditions |
|---|---|---|---|---|
| Spring Mar–May | Day 5°C / Night −12°C | Day 12°C / Night −4°C | Low (15%) | Clear mornings, afternoon clouds. Rhododendron blooms at mid-altitude. |
| Monsoon Jun–Aug | Day 12°C / Night 2°C | Day 18°C / Night 8°C | High (80%) | Wet trails, leeches, flight disruptions. Mustang & Nar Phu remain dry. |
| Autumn Sep–Nov | Day 3°C / Night −15°C | Day 10°C / Night −6°C | Minimal (5%) | Stable, deep blue skies. Best visibility of the year. Peak trail traffic. |
| Winter Dec–Feb | Day −5°C / Night −25°C | Day 2°C / Night −15°C | Moderate (25%) | Very cold. High passes often blocked. Lower valley routes excellent. |
