Is it still hot after beginning of autumn in 2023?

It will still be very hot after beginning of autumn in 2023.

Beginning of autumn time in 2023 is on August 8th, which is the middle of the dog days (July 22nd to August, 2023 10). The dog days are the hottest time of the year, and the hottest stage is the upper abdomen. Beginning of autumn only represents the arrival of autumn, not autumn in the meteorological sense.

The hot weather will only disappear after the summer vacation. The summer vacation in 2023 will be on August 23rd, which means it will be at least half a month after beginning of autumn. According to the traditional three-volt calculation, the solar terms in beginning of autumn are in the three-volt period, so the weather is still very hot after the solar terms in beginning of autumn. Generally, I don't come out until the summer heat is over.

Early autumn and late autumn:

Early autumn and late autumn are calculated according to the variation offset of the solar meridian before and after beginning of autumn. The solar ecliptic refers to the east longitude position of the sun on the ecliptic, based on the vernal equinox. Every year, beginning of autumn marks that the longitude of the sun is 135 degrees. At this time, the sun moves from south to north. Therefore, after beginning of autumn, the angle of sunlight becomes smaller, and the temperature gradually drops. In the calendar, taking beginning of autumn as a solar term can explain the change of the sun's running position more accurately and provide reference for agricultural production.

Beginning of autumn has long meant that the time node in beginning of autumn falls before August 7th, while that in beginning of autumn falls on or after August 8th. Secondly, take the specific time as a reference. Early autumn refers to the period from 0: 00 to 12: 00, and late autumn refers to 12: 24.
