Nepal Weather by Month: 2026 Guide for Trekking & Tours

2026 Seasonal Overview at a Glance

Nepal’s topography ranges from subtropical plains to the highest peaks on Earth. Consequently, Nepal weather by month varies drastically by altitude.

SeasonMonthsClimate SummaryBest Activities
SpringMarch – MayWarm days, blooming floraHigh-altitude trekking, Peak climbing
Summer/MonsoonJune – AugustHeavy rain, lush greeneryMustang trekking, Cultural tours
AutumnSept – NovCrisp air, clear skiesEverest/Annapurna treks, Festivals
WinterDec – FebCold, sunny daysLow-altitude treks, Jungle safaris

Spring (March – May): The Bloom Season

Spring is arguably the best time for high-altitude adventures. As the winter snow melts, the rhododendrons bloom, painting the hillsides in shades of red and pink.

March & April

These months offer moderate temperatures. In Kathmandu, daytime highs reach 25°C, while the mountains remain cool. It is the peak season for the Everest Base Camp trek.

May

May is the warmest pre-monsoon month. While heat builds in the Terai (reaching 35°C+), it is the primary window for Everest summits due to the stable “weather window” before the rains.

Summer/Monsoon (June – August): The Emerald Phase

The monsoon brings 80% of Nepal’s annual rainfall. While the mountains are often obscured by clouds, this is a unique time for B2B partners to promote rain-shadow regions.

June & July

Expect daily downpours, mostly at night. Leeches and slippery trails make most treks difficult. However, regions like Upper Mustang and Dolpo remain dry and beautiful as they sit behind the Himalayan rain shadow.

August

The landscape is at its greenest. It’s an excellent time for wildlife enthusiasts to visit Chitwan, provided they are prepared for high humidity. For more on entry during these months, see our visa services page.

Autumn (September – November): The Golden Window

When travelers search for Nepal weather by month, Autumn is the most recommended period. The monsoon washes away the dust, leaving behind the clearest mountain views of the year.

  • September: The rains recede, and the trekking season begins.
  • October: The “perfect” month. Stable weather and major festivals like Dashain make it the busiest time for group packages.
  • November: Dry and cool. Perfect for photography and long-distance trekking.

Winter (December – February): The Quiet Skies

Winter in Nepal is often misunderstood. While it is cold at high altitudes, the skies are strikingly blue and the trails are remarkably quiet.

January

This is the coldest month. Night temperatures in Kathmandu can drop to 2°C, and Everest Base Camp can hit -20°C. However, daytime sun is brilliant. We recommend low-altitude treks like the Ghorepani Poon Hill circuit.

February

Late February marks the transition back to Spring. It is an ideal time for B2B operators to arrange budget-friendly tours before the Spring rush. Check our B2B tours management for wholesale winter rates.
