When will it be a little cooler?

After beginning of autumn, the weather will be a little cooler, but it should be based on the actual temperature.

Because 24 solar terms such as "beginning of autumn" belong to astronomy. In order to sow and harvest in time, it is necessary to distinguish the seasons accurately, so the ancients set the 24 solar terms in the form of "vertical pole silhouette". Due to the climate difference between north and south, it is easy to find that the real climate does not match the solar terms.

In meteorological sense, the criterion of "autumn" depends on the change of temperature. When the average temperature is below 22 degrees Celsius for five consecutive days, the first day of these five days is the "autumn" day of that year. After beginning of autumn, he was still in the dog days, and the autumn tiger was eyeing him. "Autumn Tiger" is a folk description of the short-term high temperature weather in beginning of autumn, which generally appears at the turn of August and September and lasts for about 7- 15 days.
