Climate - NEPAL

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.

Nepal has four climatic seasons.
a) Spring: March-May
(b) Summer: June-August
(c) autumn: September-November
(d) Winter: December-February.

The monsoon is approximately from the end of June to the middle of September. About 80 per cent of the rain falls during that period, so the remainder of the year is dry. Spring and autumn are the most pleasant seasons; winter temperatures drop to freezing with a high level of snowfall in the mountains. Summer and late spring temperatures range from 28ºC (83ºF) in the hill regions to more than 40ºC (104ºF) in the Terai. In winter, average maximum and minimum temperatures in the Terai range from a brisk 23C (74ºF) to a mild 7ºC (45ºF). The central valleys experience a minimum temperature often falling bellow freezing point and a chilly 12ºC (54ºF) maximum. Much colder temperatures prevail at higher elevations. The Kathmandu Valley, at an altitude of 1310m (4297ft), has a mild climate, ranging from 19-27ºC (67-81ºF) in summer, and 2-20ºC (36-68ºF) in winter.
