When is the hottest day in summer?

The hottest summer is from the middle of July to the middle of August. The hottest day in summer is dog days. Three volts refers to the initial, middle and final volts. After the summer solstice, although the days are getting shorter and longer, the days are longer than the nights, and the heat absorbed by the ground is more than the heat emitted, and the temperature near the ground is higher.

Heat is in three volts: during three volts, the heat absorbed by the ground is almost less than the heat emitted, and the weather is the hottest. After that, the heat absorbed by the ground began to be less than the heat emitted by the ground, and the temperature gradually decreased. Therefore, the hottest time of the year generally appears in the dog days from summer to Sunday. As for the hottest solar term, summer solar term is the hottest solar term in a year.

The reason why it is unbearable during the hot summer is that since the beginning of summer, the heat absorbed from the ground sun during the day is more than the heat emitted at night, and the heat is constantly accumulating. During the summer heat, the accumulated heat reaches its peak, so the summer heat is the hottest.

First, second, it's the hottest day of the year. Although it is already beginning of autumn in dog days, it is still very hot, so it is also called autumn tiger. Because the first day, the second day and the third day are very hot, it is called the third day fever.
