How many days is it rainy?

The rainy season is usually about 34-40 days.

Meiyu season is a climatic phenomenon that the warm and humid air flow from the Pacific Ocean brought by the southeast monsoon passes through the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, south-central Japan and south Korea every June and July.

In the rainy season, the air humidity is high and the temperature is high, so clothes are easy to get moldy, so some people call the rainy season "moldy rain". After the rainy season, the weather began to be dominated by the Pacific subtropical high and officially entered the hot summer. Meiyu mainly occurs in the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, Liaodong Peninsula, the southernmost tip of the Korean Peninsula and the subtropical monsoon climate zone in south-central Japan.
