There are many frontal rains in spring and early summer, and many typhoons in summer and autumn. The direction of monsoon circulation is basically orthogonal to the direction of the main mountains, and the mountains play a role in blocking the cold current and typhoon in the north.

The average annual precipitation is 1600mm, in which it is rainy from April to June, accounting for 50%, which is prone to floods, and it accounts for 20% from July to September, with frequent droughts. The annual and inter-annual variation of river runoff is great, such as Luchibu Station in Fuchunjiang River, with a control area of 3 1.700 square kilometers, and the annual ratio of measured runoff to high runoff is 5: 1.
