What's the weather like in August in Zhangye, Gansu? Do you need to cover your temples with a quilt if you live in a dormitory at night? Are there any mosquitoes?

No one can say for sure about the weather, but it has been sunny in recent days. The temperature is about 35- 17 degrees, the relative humidity is 43%, the wind direction is southeasterly, about level 3, and there is a breeze. It will be sunny in the next 4-7 days, and the temperature may rise, so I forgot to cover the quilt, but I still need to cover it thinly. The temperature difference between day and night is very large. I suggest covering it well, and of course there are mosquitoes!
