Trekking in Nepal can be undertaken throughout the year. There are four seasons in Nepal. Each season has its distinct attraction to offer. The Nepal trekking season is classified as follows:
This Autumn season is considered the best time for trekking in Nepal, which offers excellent weather and tantalizing mountain views. Moderate temperatures, clear sky with outstanding views, making it a great time to do any of our trek. Occasional short storms may dump snow at high altitudes.
This season is noted for occasional snowfall at higher elevations in Himalayas. Though it gets colder in night, often it offers the clear day / blue sky and relatively less trekkers on the trail. However, we need to be selective in choosing the winter trekking as climbing and crossing high passes trip won’t be an ideal option. Trek like Everest base camp, Annapurna Panorama, Annapurna Dhaulagiri, Annapurna Sanctuary, Instant Everest treks etc can be done even in winter.
Different varieties of wild flowers, specially the rhododendrons make the hillside a haunting paradise during this spring season. It is mildly warm at lower elevations and at higher elevation the mountain views are excellent and temperature is quite moderate.
summer time from June till mid September makes travel wet and warm. These times are blessed for the keen botanist as the higher valleys and meadows blossom with flowers and lush vegetation. Trekking in the rain-shadow (places are out of reach of the rain clouds because of the high mountains) areas north of the Himalaya like Upper Mustang and Dolpo could be an ideal trek selection.
