What is the weather like in Lhasa, Nyingchi and Namtso in mid-October? Is it cold?

In mid-October, there is not much difference between autumn in Nyingchi and the plains. Due to the high altitude, Lhasa will be a little cold sooner or later, but it will be warmer as long as there is sunshine during the day. Special attention should be paid to Namtso. Sometimes it has started to snow, although it snows heavily It will take some time before the mountain is closed, but the temperature at night may drop to zero, and the incidence of high altitude sickness will be much higher than in summer, so adequate preparations must be made psychologically and in cold-proof clothing.
