Weather in places in Yunnan Province

For these detinations, during Jan. the highest temp will be 15C or a little higer, but the lowest temp may be only nearly 0C and around. In Feb. it will be a little warmer, with the average temp of about 15C, but sometimes, the lowest temp will be only 3C.
So I suggest you take along sweater and cardigan for Jan. and a light coat and jeans for Feb.
