We will go to Lhasa in the middle of May. How is the weather and temperature during that period ?

Hi, it will be sunny and warm. The temperature range shall be around 13C to 26C. But the lowest temp may suddenly fall to 6-8C at cool night. Therefore, the big temp gap requires you to take a jacket to keep warm. According to the past weather records, it may also shower sometimes. I suggest you pay attention to the weather forecase before outing.
