Is the solstice in summer the hottest day?

Generally speaking, the summer solstice is not the hottest day in a year, but what is certain is that it will definitely get hotter after the summer solstice. The specific reason is that after the summer solstice, although the direct point of the sun began to move south from the Tropic of Cancer, the days in the northern hemisphere began to shorten gradually.

However, because the heat radiated from the sun to the ground is still much more than that radiated from the ground to the air, the temperature will continue to rise in the future, so there is a saying that it is not too hot from summer solstice. As the saying goes, "three volts is hot." The real hot weather is from mid-July to mid-August on the Gregorian calendar, which is the hottest time.

Summer solstice

The summer solstice is the 10 of the 24 solar terms. Fighting means noon; The yellow meridian of the sun is 90 degrees; June 2 1~22 of Gregorian calendar. On the day of summer solstice, the position where the sun shines directly on the ground reaches the northernmost part of the year, almost directly on the tropic of cancer. At this time, the daylight hours in all parts of the northern hemisphere reach the longest in the whole year. For the Tropic of Cancer and its northern region, the summer solstice is also the highest day at noon in a year.

The solstice in summer is the turning point of the sun's northward movement. After the summer solstice, the direct point of the sun began to move south from the Tropic of Cancer, and the days in the northern hemisphere began to shorten gradually. For the area north of the Tropic of Cancer in China, the height of the noon sun begins to decrease day by day from summer to the future. For the area south of the Tropic of Cancer in China, the height of the sun returns to the south from summer to noon in the future, and it begins to decrease day by day after the sun shines again.
