When is the rainy season in Zhejiang?

The rainy season in Hangzhou generally begins in early June and ends in early July, and the rainy season is about 1 month. Meiyu refers to a period of continuous rainy weather from mid-June to early summer in mid-July, from the middle and lower reaches of the Yangtze River in China to 28°-34° N east of Yichang, or the Jianghuai Valley, to a narrow area in southern Japan. In early summer, there are often long rainy days in the Jianghuai basin. At this time, the utensils are easy to be moldy, so it is also called "moldy rain" or "mildew" for short; It is also called "Plum Rain" or "Huang Meiyu" because plums in the south of the Yangtze River are yellow and ripe. After mid-June, the rain belt remained in the Jianghuai basin, which is Meiyu.

Normal Meiyu in the middle and lower reaches of the Yangtze River begins in mid-June and ends in mid-July, which is in the two solar terms of "ear seed" and "summer solstice". The meiyu period is about 20-30 days, and the rainfall is between 200-400 mm. Before and after "Little Summer", the main rainfall belt moves northward to the Yellow River and Huaihe River basins, and then to Shandong and North China. The Yangtze River basin began to change from rainy and humid weather to sunny and hot summer. According to statistics, this normal plum rain accounts for about half of the total. In some years, the rainy season starts very early and suddenly comes at the end of May and the beginning of June. Meteorologically, the plum rain that began before "Mangzi" is generally called "early plum rain".
