How long will the hot weather in the south last?

The hot weather in the south lasts about 2 months, basically in July and August, and gradually cools down from September.

Mainly affected by subtropical high. Judging from the current monitoring, the western Pacific subtropical high has a large range and strong intensity this year. Under its control, the southern part of China was controlled by downdraft as a whole, resulting in partly cloudy and clear skies. Coupled with the influence of sunshine radiation during the day, the near-surface heating is strong, and the hot air stays on the ground and cannot be blown away, so there is a wide range of continuous high temperature weather.
