I'll go to huangshan the end of March , how about the weather ? Thanks.

Currently, it is hard to tell the exact temperature, because it is so early.
According to the past situation, the temperature is around 5 to 10C if the weather is fine. If it rains, the temperature is around -1 to 5C.
No matter what kind of weather, a thick coat is necessary, because it is windy on the top of the mountain.
