When is the date of high temperature in summer? What does this festival stand for?

July 6th to 7th and 8th every year is a light summer time, which means the weather is getting hotter, but it is not the hottest.

Since the beginning of summer, the plum rains in the Jianghuai basin have ended one after another, and the southeast monsoon rainy season from the Pacific Ocean has begun in the vast areas north of the Huaihe River and east of the Qinling Mountains. The precipitation has increased significantly and the rainfall is relatively concentrated.

South China, Southwest China and Qinghai-Tibet Plateau are also in the southwest monsoon rainy season from the Indian Ocean and South China Sea, while the middle and lower reaches of the Yangtze River are generally hot and rainy under the control of subtropical high.

In some years, the cold air force in the north is still strong before and after the slight summer heat, and it is evenly matched with the warm air in the south in the middle and lower reaches of the Yangtze River, leading to frontal thunderstorms. Thundershowers in summer are often the weather information of "yellow plum falling", which indicates that the rain belt will stay in the middle and lower reaches of the Yangtze River for some time.
