When did Wuchuan in Zhanjiang start to get cold?

Hello, not only Wuchuan, but also Guangdong.

Generally, the temperature drops every year 165438+ 10. ....

I'm from Wuchuan. From my personal experience, I think it turns a little cold after the mid-term exam in the first semester and a little hot before the mid-term exam in the second semester, that is, around the end of April in early June every year.
