Best overall months
March to May and October to November are the most reliable all-round months for Nepal. Spring brings warmer trekking conditions and rhododendron blooms, while autumn usually has clearer skies after the monsoon. These windows are also the busiest, so flights, guides, and lodges should be arranged early.
- March to May: warmer days and flowering hillsides
- October to November: clearer views and stable trails
- December to February: quieter lower-altitude travel
- June to August: useful for rain-shadow regions and flexible travelers
Choosing by trip type
High-altitude trekking favors stable weather and clear visibility, helicopter tours need calm flying conditions, wildlife trips depend on grass height and temperatures, and cultural tours can work across much of the year. The right season should match the activity rather than follow a single rule.
- Trekking: spring and autumn
- Helicopter tours: October to May
- Wildlife: October to April
- Festivals: dates change by lunar calendar
How to plan around weather
Weather in Nepal is regional. Kathmandu, Pokhara, Chitwan, Everest, Annapurna, and rain-shadow areas can behave differently in the same month. Build buffer time around mountain flights, keep route alternatives ready, and avoid planning a tight international connection after a Lukla flight or high mountain return.
