I'll be sleeping outdoors, and trekking up to around 2100m above sea level, north of Pokhara, near Naya Phul. Can anyone tell me how cold I can expect it to be and the likelihood of there being snow?
Temperatures in spring and late summer typically range between 28 º C (83 º F) in mountainous regions and over 40 º C (104 º F) in the Terai. In winter, the maximum and minimum temperatures in the Terai range from 7 º C (45 º F) and 23 º C (74 º F). The central valleys recorded a very low minimum temperatures and a maximum of 12 º C (54 º F). The temperatures are much cooler at high altitudes. The Kathmandu Valley, with a height of 1,310 m (4297 feet), shows a moderate temperature 19-27 º C (67-81 º F) in summer and 2-20 º C (36-68 º F) in winter.

Proper Clothing Light Clothing and tropical umbrella during the months of June through August. Between October and March are advised to take light clothes in Kathmandu, a jacket and warm clothes when visiting the mountains.

about 80% rainfall occurs due to the monsoon in Nepal. so that is no remarkable difference between average annual rainfall and the average monsoon rainfall. like the pattern if annual rainfall, monsoon rainfall pattern also deceases from the east to the west. the western Nepal also receives higher monsoon rainfall compared to annual rainfall.
the summar monsoon originates in the bay of bengal and moves along the soithern flanks the Himalayas. thus, rainfall decreases from east to west. it is heavily concentrated in the southern part of Annapurna region.eastern Nepal and in the langtang area. the northern part of the mid west and far west receives less monsoon rainfall compared to other parts of the country.
the maximum rainfall has been recorded at lumle in pokhara. unlike mean annual rainfall, the north western part of the country also receives higher amount of rainfall in summers.
