What month is the rainy season in Hangzhou?

The rainy season in Hangzhou is from mid-June to late June and from early July to mid-July.

Meiyu season is a warm and humid air flow in the Pacific Ocean brought by the southeast monsoon in June and July every year, which passes through the middle and lower reaches of the Yangtze River in China, Taiwan Province Province in China, south-central Japan and south Korea. Because it is the mature period of plums in Jiangnan, it is called "Meiyu", and this period is called Meiyu season. At present, the academic circles believe that the East Asian summer monsoon began in the South China Sea summer monsoon (in late May on average) and belongs to the category of tropical southwest monsoon. The summer monsoon in the South China Sea gradually strengthens northward, and it is carried northward to the middle and lower reaches of the Yangtze River during the meiyu period, where it merges with the subtropical southwest monsoon on the northwest side of the subtropical high, cold air and wind speed to form the meiyu belt.
