Fresh air and clear skies are the main reasons why October to November is the best time to visit Nepal. Views during this period are scenic, so trekking is perfect. Autumn also hosts two major holidays, Dashain and Tihar. December to early February are relatively warm in the daytime and freezing at night. Winter sees quieter trekking trails and fantastic whitewater rafting, but we recommend to dress warmly. Mild spring starts in March and is a lovely time to explore Nepal as rhododendrons bloom in the Himalayas. Clouds obscure mountain panoramas and trails get muddy from June to August as it is the monsoon season. However, the temperatures are gentle, and the sightseeing is more fun with fewer tourists and a variety of festivals like Gathia Mangal.
