What's the best weather to go to Qinghai Lake?

Hello, it is best to go from cloudy to cloudy. The altitude of Qinghai Lake is higher. If it is cloudy or cloudy, the air pressure will be higher than that in sunny days, and Qinghai Lake will be more poetic and interesting under the care of clouds. But it's best not to go when it rains, which will also spoil the fun. Thank you.
