What's the weather like in Kaiyuan, Yunnan in summer?

It's so hot ~ ~ ~ The sun at noon is almost irritable. Of course, you are from other provinces, so you should be quite adapted. But it's better to cool down in the morning and evening, and it won't be so hot at night. Honghe Prefecture is an ancient city with good climate and economy. Kaiyuan is an industrial city, and the smell of the PLA chemical plant is not very good in hot summer.
