Why does it rain every year during the Dragon Boat Festival?

It is still different all over the country. But it rains in most places.

Because every year to the Dragon Boat Festival is the active period of the subtropical high at sea, the southwest airflow from the north side becomes more active and vigorous, and after the southwest airflow is strengthened, there will often be heavy rain brought by the jet stream.

Dragon Boat Festival is very hot in most parts of China, especially in the central and southern regions. China's rainfall area moves northward, and the rainfall is generally not strong. The main rainfall areas are located in the east of southwest China, south of Jianghuai, south of Yangtze River and South China, and the accumulated rainfall is generally 30-60mm, including 80-130mm in parts of south of Yangtze River and South China, and10-30mm in northwest Xinjiang, east of northwest China, north China and northeast China.
