The season of Nepal is not like that of Saudi Arabia where you experience an unending marathon of dryness. Nepal has multiple seasons; June, July, and August are the seasons in which you experience heavy rainfall. The best months to make your trekking entertaining in Nepal are September to May. The seasons of Nepal have been divided into four segments. These will help you to make the trekking decision better.
Autumn (September to November)
Trekking Season that is Autumn is the best because it is packed with everything, for example, excellent mountain view and fine weather. This is what makes the trek completely different, unfolding all its characteristics that will meet your desires.
Winter (December to February)
As it snows in winter, it is difficult to trek at higher elevations. So, trekking at lower altitudes especially below 3000 meters is recommended during this trekking season. This time trekkers can trek around Pokhara like Ghorepani poon hill, Royal trek, around Kathmandu such a Chisopani Nagarkot trek as well as Chandragiri hiking and tour around Kathmandu valley, Chitwan jungle safari, Lumbini pilgrims tour, Tansen Palp, and Pokhara tour.
Spring (March to May)
Spring is another great season to trek because of the excellent weather and clear mountain views. This season is also high season for the expedition, thousands of mountaineers summit Everest and other similar peaks during this season. Wildflowers like Rhododendron are in full bloom in the spring season, and they can be seen in most of the trekking trails across Nepal.
Summer (June to August)
Due to the monsoons in summer trekking is generally not recommended during this season. However, keen botanists may find it worthwhile to trek at lower altitudes during this season because of the blossoming wildflowers and lush vegetation. Nepal and Tibet have some of the rain shadow regions such as Upper Mustang, Upper Dolpo, Humla, and Mount Kailash in Tibet. So, you will not face any kind of problems visiting these regions even in the monsoon season.
