The summer solstice is the 10 of the 24 solar terms. At this time, it means noon, which is also the northernmost day of the sun in a year, the pole of the sun moving northward, and the longest day in the northern hemisphere.

What are the characteristics of summer solstice?

1, the sun is northernmost.

The solstice in summer happens to be the northernmost day of the sun, that is to say, the northward movement of the sun has reached the extreme. After this day, the sun began to walk back, and the height angle of the sun began to decrease day by day at noon.

The day is the longest.

On the day of summer solstice, the northern hemisphere has the longest day time and the shortest night time. After this day, the daytime in the northern hemisphere gradually began to decrease, as the ancients said: "The days are long and the shadows are short, so it is called summer solstice."

3, not the hottest time

On the solstice of summer, although the day is the longest and the sun angle is the highest in the north of the Tropic of Cancer, it is not the hottest time of the year, and the heat on the surface is still accumulating and has not reached a high point. As the saying goes, "it's hot in dog days." The hottest weather in a year may be around beginning of autumn, that is, from mid-July to mid-August in the Gregorian calendar.
