Tibet is in a high plateau, and it belongs to typical downy special climate. Climates are quite different in different areas of Tibet. The eastern Tibet which is at a lower elevation is warmer than western Tibet. In some mountain areas, there are four seasons at the same time in different altitude. The weather in a day varies greatly, too. The night is cold while the day is warm. It spans 12-15 degrees centigrade in a single day.
Climate in southeastern Tibet including Nyingchi and Chamdo is balmy with an average temperature of eight degrees centigrade; while in western Tibet (Shigatse and Nagqu) is quite cold with an average temperature below zero degree.
However in the central area of Tibet, the climate of Lhasa and Tsedang is more favorable for traveling. Travelers can visit these two areas all year around, not too hot in summer and not too cold in winter.
