Which solar term is the hottest?

As the saying goes, the hottest dog days in summer. The dog days are the initial, middle and final dog days, and they are the hottest season in a year. It appears from mid-July to mid-August in the solar calendar every year. Its climate is characterized by high temperature, low pressure, high humidity and low wind speed. "V" means being forced to hide underground. According to the climate law of the lunar calendar in China, predecessors have long stipulated: "The third Geng day from long summer to the future is the beginning, the fourth Geng day is the middle (second), and the first Geng day after beginning of autumn is the end (third), every ten days * * * 30 days." In some years, the "mid-crouch" is 20 days, while * * * is 40 days.
