What is the average temperature in Lhasa in October?

If it's for fun, October is good. It is mild during the day, about 20 degrees, but it is very cold at night, usually 0 degrees, and it will snow. The oxygen content in Lhasa in winter is lower than that in summer, and it is drier than that in summer. Because there are few clouds, ultraviolet rays are stronger than in summer. But you can see snow. Oh, that's interesting. Another point is that there are fewer tourists than in summer, so the cost of accommodation is lower.
