In which months will Guangzhou get hotter and cooler?

Guangdong only gets cooler in October.

According to past data, Guangdong will enter autumn in mid-to-late October and the weather will turn cooler. The specific regions may be slightly different. For example, autumn will begin in early October in northern Guangdong, and it will arrive at the end of October in the Pearl River Delta.

Under normal circumstances, it takes until the second half of October for the autumn wind to reach Lingnan and Guangxi. The coastal areas of Guangdong and Guangxi and the northern part of Hainan Island will not feel the autumn coolness until the first half of November. In the southern part of Hainan Island, summer will turn to autumn in December. By then, winter has already entered the Daxinganling Mountains in the northeast for more than three months.
