When is the hottest in summer?

The hottest time in summer is midsummer, which starts on the day around July 23rd, and is usually the hottest in the half month between July 25th and August 10.

In summer, the hottest time is dog days. "Three volts" refers to the first, middle and last three volts, which is from mid-July to mid-August every year. After the summer solstice, although the days are getting shorter and the nights are getting longer, the days are longer than the nights in a day. Every day, the ground absorbs more heat than it emits, and the temperature near the ground is getting higher every day.

During the "three volts" period, 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 the summer solstice. The hottest time in the dog days is in the middle, usually ten to twenty days.
