When will autumn come?

The autumnal equinox in 2023 is at 2: 22: 4 1 sec on August 8, which is Tuesday, June 22 of the lunar calendar.

Beginning of autumn is the 13 of the 24 solar terms, and the first solar term in autumn usually falls on August 7th or 8th of the Gregorian calendar every year. Beginning of autumn doesn't mean the hot weather is over. Beginning of autumn is still in the summer heat period, but the summer heat will not come out until the second solar term in autumn, and the weather is still very hot in early autumn.

Beginning of autumn is divided into three stages: one is when the cool wind comes; Second, wait for the white deer to be born; Three are waiting for cicadas to sing. This means that after beginning of autumn, people will feel cool when it is windy, and the wind at this time is different from the hot air in summer.

Then, there will be fog on the ground in the morning, and cicadas will begin to sing in autumn when they feel gloomy. In fact, in most parts of our country, it is still very muggy from beginning of autumn to summer, and there is no such phenomenon as cool breeze, dew and chilling sound.

Phenological phenomena in early autumn

Some ancient literary works in China divide beginning of autumn into three periods: one is waiting for the cool breeze; Second, wait for the white deer to be born; Three are waiting for cicadas to sing. This means that after beginning of autumn, people will feel cool when it is windy, and the wind at this time is different from the hot air in summer; Then, there will be fog on the ground in the morning, and cicadas will begin to sing in autumn when they feel gloomy.

In fact, in most parts of our country, the period from beginning of autumn to the summer heat is rather sultry, and there is no such phenomenon as cool breeze, dew and chilling sound during this period. According to the order of the twenty-four solar terms, there is a solar term of summertime after beginning of autumn, which means summertime, but it hasn't been summertime in beginning of autumn.

The so-called "heat is in the dog days", which involves four solar terms: summer, summer, beginning of autumn and early summer, and is the period with the highest temperature, humidity and sultry weather in a year.
