Lasa Outlook

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 coldest month is January with an average temperature of −1.6 °C (29.1 °F) and the warmest month is June with a daily average of 16.0 °C (60.8 °F), though nights have generally been warmer in July.The annual mean temperature is 7.98 °C (46.4 °F), with extreme temperatures ranging from −16.5 to 30.4 °C (2 to 87 °F).Lhasa has an annual precipitation of 426 millimetres (16.8 in) with rain falling mainly in July, August and September. 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). Summer is widely regarded the "best" of the year as rains come mostly at night and Lhasa is still sunny during the daytime.
