Weather In Nepal
Nepal climate varies according to its season. Autumn and spring are the two most favorable seasons for trekking in Nepal. Autumn starts from early September to early December and brings in clear weather with sunny days and warm nights. Whereas spring starts from the beginning of March to the end of May with occasional rain falls. From June to September, is the monsoon season. Trekking is generally difficult and uncomfortable as the climate of Nepal at this time of year brings about hot weather and rain falls almost every day. The trails become muddy and are often leech-infested. Moreover, the mountains are usually obscured by cloud. There are, however, possibilities for summer trekking in the trans-Himalayan regions of Mustang, Dolpo and Humla. These regions lie in a rain-shadow and therefore receive significantly less precipitation than the more southerly areas.
Autumn (September to November)
Autumn is an ideal time to visit Nepal. The countryside is green and lush and Nepal looks its most beautiful. The air is sparkling clean, affording near perfect Himalayan vistas. As the weather is neither too hot nor too cold, this is peak tourist season and it is also the main season for Nepalese festivals. However, in the higher altitude, the nights drop into freezing temperature. In this season, the mountains views are astonishingly clear.
Winter (December to February)
Winter can be a hauntingly beautiful time of the year to trek. The climate and visibility are still good, excellent clear views are common at high altitude but it can get very cold. You need to be prepared to encounter snow on the high altitudes and the higher passes may be closed.
Spring (March to May)
In spring, the mornings are usually clear but afternoon cloud build-up brings occasional showers. The days are mix up with warm and rain, which displays wildflowers like rhododendrons. The whole country is lush and an abundant green at this season. This period instigate the second most popular and pleasant trekking season as this is rice-planting time. Late-march into April is especially beautiful. It is also a good time for climbing as the high passes are usually snow free and the mountain views are still clear in April. Up to May, the weather becomes hazy and disturbed with the clouds.
Summer/Monsoon (June to August)
June to August is warm and wet but these months are blessed for the keen botanist as the higher valleys and meadows blossom with flowers and lush vegetation. Generally the morning is cloudy and the cloud wisps form on random ridges and peaks. Trekking at this time of year is generally uncomfortable as the weather is hot and the rains. There are, however, possibilities for trekking in the trans-Himalayan regions of mustang, Dolpo and Tibet. These regions lie in a rain-shadow and therefore receive significantly less precipitation than the more southerly areas.
