What is the temperature and time of rainy season?

The middle and lower reaches of the Yangtze River in China are usually from mid-June to early July every year.

Meiyu period lasts about 20-30 days, and the rainfall is between 200-400 mm.

Because in the early rainy season, cold air from north to south is still very frequent in the atmosphere near the ground, after the rainy season begins, the temperature is still relatively low and even chilly.

So the temperature is uncertain. The range is between 14 degrees and 24 degrees.
