Usually it rains at night in Lhasa, Shigatse and Chamdo area. The precipitations gradually decrease from 5000 millimeters in the lower part of southeast to just 50 in the northwest.

At higher elevations (ie above 4000m) even summer days can be chilly. During spring and autumn you need to be prepared for four seasons in one day, including the possibility of snowfall.

The temperature decreases along with the rise of altitude and latitude. Travel to Tibet, you should pay attention to the climate of Tibet and prepare well according to weather forecast.
