The characteristics of beginning of autumn

"beginning of autumn" is in the first half of August in the Gregorian calendar, which is used to mean beginning of autumn, but the temperature has not dropped to the standard of crisp autumn, so there is a saying that "the dog days are endless". The temperature began to drop, with an average temperature of 26-27℃ and the highest temperature still above 35℃. It's usually a little cold in the morning and evening, and it's still hot around noon. Precipitation began to decrease, generally 70-80 mm, accompanied by strong winds and heavy rains, but there were also droughts in early autumn in some years. Generally speaking, sufficient light is beneficial to the growth and development of early autumn crops.

Beginning of autumn just means the beginning of autumn, and the heat has not completely passed. It will not dissipate until after the heat, and the weather will gradually turn cold.

Based on years of experience, the Han people summed up the saying of twenty-four autumn tigers, which was widely circulated. This means that if it doesn't rain in beginning of autumn every year, it will be very hot in the twenty-four days after beginning of autumn, so it is called the twenty-four autumn tiger.

If it rains that day in beginning of autumn, even if it is light rain, it is also called "Shun Qiu". There is a saying among the Han people that an autumn rain is followed by a cold, which means that the weather will become cooler and more pleasant after the autumn.
