Nepal has two seasons - the dry season from October to May and the rainy, monsoon season from June to September. Early spring (March to April) and late autumn (October and November) are the best times to visit, and also offer the clearest mountain views and good weather for trekking. From December to February there is snow on the mountains with freezing temperatures at high altitudes, while the summer months of June to August can be very hot for general travel.
The Kathmandu Valley has a mild climate most of the year, situated at an altitude of 4,297ft (1,310m). Summer temperatures range from 67-81°F (19-27°C), and in winter temperatures are between 36 and 68°F (2-20°C). During the rainy monsoon season between June and August, there is an average rainfall of between 7.8-14.7 inches (200-375mm) in Kathmandu. May and June can be very hot and humid until the monsoon rains bring relief. In spring (March to April) and autumn (October to November) the temperatures are pleasant with occasional short bursts of rain, while November to February are dry, but can be very cold, especially at night. |
