The best time to visit Nepal is from October to December. The autumn months of October and November are touted as the best time for trekkers who are rewarded with clear skies and breathtaking views. During this season, the weather is typically dry, offering excellent visibility of the mountains and trekking trails. The temperatures are moderate and comfortable, making it ideal for outdoor activities. The next best time to visit Nepal is in the spring season, from March to April. The rhododendrons are in bloom, and the temperatures are warm yet not scorching hot. The winter months are ideal for those wishing to vacation in Kathmandu and low-lying areas.
Winter in Nepal, particularly in the lower elevations, can be cold, especially during the mornings and evenings. However, daytime temperatures are still pleasant and suitable for activities in regions like Kathmandu and Pokhara. In the higher elevations, especially in the mountains, trails might experience snow and colder conditions. However, trekking is still possible in certain regions like the Annapurna Circuit or lower altitude treks.
The monsoon from June to August brings heavy rainfall to Nepal, making it the least favorable time for trekking and outdoor activities in most regions due to landslides, muddy trails, and limited mountain views. However, regions like Mustang and Dolpo, located in rain shadow areas, might still be accessible and suitable for trekking during this time.
