Lhasa lies in a small basin and the topography is plain. The climate of the city is mild, without severely cold winters or extremely hot summer. The average temperature is about 8 degree Celsius.
Lhasa enjoys the reputation of “sunshine city” because the annual sunshine time reaches 3,000 hours, 1,800 hours more than that of Chengdu City, and 1,100 hours more than that of Shanghai City. The annual rainfall is 500 mms and the rainy months are July, August and September.
"Night rain” is a unique phenomenon in Lhasa because rain usually falls at night. In the day, it is often sunny and bright. But when night falls, rain also falls, washing away the heat and dust of the day, and cleaning the streets.
