BEST TIME TO TRAVEL
There are 4 seasons in Nepal according to the local climate. The best time to travel in Nepal is in spring (February to May) and autumn (September to November). But especially Upper Dolpo and Upper Mustang trekking can do in the Spring, Summer and Autumn. The temperature is moderate in these seasons and guarantees amazing views through the trip. Although this trek can be undertaken during winter, the cold temperature might not be suitable for everyone.
Autumn:
During the months of September, October and November, temperatures above the altitude of 4500m minimum -10 ° C maximum 15 ° C and minimum 5 ° C maximum 15 ° C below 1500M altitude. And the sky is normally deep blue, the sun is often bright and the view of the mountains mostly crystal clear, the temperature during the day is rather pleasant. This is an excellent time for tourism and trekking in Nepal.
Winter:
Begin from December to February, temperatures above the altitude of 4500m minimum 15 ° C maximum -20 ° C and minimum 15 ° C maximum 0 ° C below altitude 1500M. Snowfall abundant sometimes make impassable several passes of high altitude. Trekking is always possible, but at altitudes below 4000m because of the cold. The weather is very clear and visibility on the mountains excellent.
Spring:
Beginning of March to May, temperatures above 4500M altitude minimum 5 ° C to maximum 20 ° C and minimum 12 ° C to 29 ° C below 1500m altitude. the days are sunny and the temperatures more and more lenient. The view of the mountains is less and less good as the monsoon approaches, but it is also the period of flowering rhododendrons, absolutely beautiful, especially in the Annapurna region.
Summer:
From June to August, temperatures above 4500m altitude minimum 5 ° C to 23 ° C maximum and minimum 13 ° C to 31 ° C below 1500M altitude in Nepal. the moist air masses of the Bay of Bengal collide with the Himalayan range. As they rise, they cool and condense to fall back in the form of rain: it’s the monsoon. Its effects are very uneven across the country. It gradually loses its intensity as it moves from the southeast to the northwest. Some regions are therefore less affected by the monsoon: the north of the Annapurna area (Manang, Naar, Phu), Haut-Dolpo and Mustang. Elsewhere, roads are sometimes slippery and often infested with leeches.
