When is it hot in summer?

The summer heat in 2023 is July 7, and the lunar calendar is May 20.

Summer is 1 1 of the 24 solar terms in China. The time of light summer is July 7 or 8 every year, and it is light summer when the sun reaches 105. So this year's light summer is July 7.

Summer heat, which means hot, is a little hot, not very hot. Slight summer heat is relative to great summer heat. The ancients thought that this was not the hottest time of the year, so it was called a slight summer heat. Slight summer heat means that the weather is getting hotter, but it is not the hottest.

Judging from the climate in summer, the probability of rain on this day is relatively high. There is a proverb related to the hot summer solar terms: "The rain hits the hot summer, and the cow doesn't need it for forty-five days." If it rains three days after the hot summer, it will not stop for the next 45 days.

There are many rainy days. Due to the continuous rainfall, the farmland is extremely muddy and the cattle can't work in the field. However, due to the hot weather around the solar terms, it is better for farmland to rain.

Meteorological changes:

In summer, the sunshine time in the northern hemisphere is gradually shortened, but why is the temperature still rising in most parts of China? This is because the direct point of the sun is moving south, but it is still directly in the northern hemisphere, and the heat in the northern hemisphere is still more than its branches, so the temperature will continue to rise during this period.

In summer, the average temperature in the south of China is about 26 degrees Celsius. In mid-July, the average daily temperature in the low-altitude valley area in southeast China was higher than 30℃, and the maximum daily temperature was higher than 35℃. In the northern part of the northwest plateau, frost and snow can still be seen at this time, which is equivalent to the scene of early spring in South China.
