Monthly possible sunshine ranges from 53 percent in July to 84 percent in November, and the city receives nearly 3,000 hours of sunlight annually. It is thus sometimes called the "sunlit city" by Tibetans.

The driest month is January at 0.8 millimetres (0.03 in) and the wettest month is August, at 120.6 millimetres (4.75 in).
