What's the weather like in Nanyang, Henan Province in September?

Nanyang in early September of the solar calendar is actually quite hot, so be sure to bring short sleeves. Girls can bring shorts and skirts, as well as one or two long sleeves and jeans in case the weather turns cold at the end of September, but you don't need to prepare a coat at all. This is normal weather, and there will be changes, but the changes are very small. . .
