When is the hottest time of the year?

Dog days, usually from July to early August.

The dog days, which appear between the summer heat and the summer heat, are the period with the highest temperature, the highest humidity and the most severe sultry heat in a year. "V" means being forced to hide underground. There are three kinds of fu: initial fu, middle fu and final fu, and their dates are determined by the solar terms and dates of the dry branch calendar.

brief introduction

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.

The stipulated initial and final stay time 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.
