What festival is the summer solstice?

Summer is the tenth of the twenty-four solar terms.

The summer solstice is the tenth of the twenty-four solar terms. This summer, the sun shines directly on the ground, directly to the northernmost part of the year, almost directly to the Tropic of Cancer. At this time, the daytime in the northern hemisphere reaches the longest time of the year. For the Tropic of Cancer and its northern region, the summer solstice is also the highest day at noon in a year.

Meteorological changes in summer solstice

After the summer solstice, although the direct point of the sun began to move south from the Tropic of Cancer, the daytime in the northern hemisphere began to shorten gradually, but the heat radiated by the sun to the ground was still more than that radiated from the ground to the air, so the temperature would continue to rise in the following time, so there was a saying that the summer solstice was not too hot. As the saying goes, "It's hot in dog days." The really hot weather is from mid-July to mid-August in the solar calendar.

When the sun shines directly on the ground in summer, it reaches the northernmost point of the year, and the northern hemisphere reaches the longest point of the year during the day. During this period, the temperature in most parts of China was high, the sunshine was sufficient, the crops grew rapidly, and the physiological and ecological water demand was large. After the summer, the ground is heated strongly and the air convection is strong, and thunderstorms often form in the afternoon to evening. This hot thunderstorm came suddenly and went quickly, and the rainfall range was small. People call it "dividing fields in summer and rain".

"Summer solstice" is the starting point of midsummer. Although it has not reached the hottest day of the year, it is not far from "cold". Starting from "midsummer", after three "Geng days", it enters the hottest dog days of the year, which is called "the first dog days of midsummer". High temperature, high humidity and occasional thunderstorms are the weather characteristics from summer to the future.
