The annual average precipitation is1100 ~1300mm, and the precipitation from April to September with high temperature accounts for about 70% of the annual precipitation.

Hanjiang river basin is an important channel for cold air to go south, and Jianghan plain bears the brunt. Low humidity and rainy weather often occur in spring and autumn, which makes the probability of dry seedling rot and empty shell rate of late rice in the second season higher. In case of years with long plum rains and heavy rains, early summer is prone to floods; Midsummer is often controlled by subtropical ridge; There are many sunny days in autumn and many droughts in summer and autumn.
