The dog days appear between the slight summer heat and the severe summer heat (from mid-July to mid-August in Gregorian calendar), and the dog days are divided into three days: the beginning, the middle and the end. Dog days are characterized by high temperature, low air pressure, high humidity and low wind speed. "crouching" means being forced to hide underground, and it also means that the weather is too hot to move. The date of the dog days is determined by the coordination of 24 solar terms and the date of the main branch.

Because every Geng day is 10 days apart, the stipulated time of the first day and the last day is 10 days. Because the third Geng Day (the first autumn) after long summer appeared sooner or later, the days of autumn were long and short. The dog days are the hottest, wettest and sultry time of the year.

The reason why the air humidity is high in dog days is that the southeast wind blows in dog days, while the southeast is the ocean and the air is humid. The humidity of the sea breeze leads to the high humidity in dog days. In dog days, "high temperature and high humidity" is the climate characteristic of southern China. The inland areas in the north are far from the ocean, and the climate is characterized by "high temperature and dryness".

"Three volts" and "three summers" (summer, summer and midsummer in the 24 solar terms) both represent high temperature and extreme weather, and the curves on the time axis and the temperature axis are basically the same: summer comes, summer comes; When the sky falls, summer is over.
