Climate of Nepal
The climate of Nepal varies extensively as you move from one region to the next. From facing the coldest and most bitter conditions on Earth to facing the sweltering heat of the plains, all happens in Nepal within a short distance. The extreme differences in temperature and climate are due to altitude variations. In general, the summers are cool in the north and the winters severe, while in the south, the summers are sub-tropical and winters mild.
