Best Time to Visit Nepal The best time to visit Nepal is during the pre-monsoon (spring) season from March to May and the post-monsoon (autumn) season from September to November. In spring, Nepal bursts with vibrant rhododendron blooms and pleasant temperatures, ideal for trekking and cultural exploration. Autumn offers clear skies, stunning mountain views, and favorable weather for trekking, particularly in popular regions like Everest and Annapurna. These periods provide optimal conditions for outdoor activities, making them the most popular times for tourists to experience Nepal’s natural beauty and rich cultural heritage.
