When is the rainy season in the south? .

The rainy season in China can be divided into south rainy season and north rainy season. Usually, the rainy season in the south begins in April and the precipitation gradually decreases in September, so April to September is the rainy season in the south; The rainy season in northern China is relatively late, starting in June and ending in September, several months later than in the south.

This is because after winter, China began to blow southeast wind, and the southern region first felt the warmth and humidity brought by this monsoon, especially in April. In addition, at this time, the cold air is still going south from time to time, and there will be obvious precipitation when cold and warm air meet. It is estimated that this wind will last until June in the north.
