It will be the hottest in a few days.

Dog days are the hottest period in a year, with the highest temperature. At this time, the weather is hot and the surface temperature can reach 40-50 degrees. Pay attention to heatstroke prevention and cooling. The hottest time in the dog days is moderate, when the surface heat will reach the highest, so the temperature is also the highest period.

"Three volts" refers to the front, middle and back three volts. There is a folk saying that "the cold is in the March 9th and the summer heat is in the middle". It can be seen that middling is the hottest day among the three volts. During the dog days, the surface humidity becomes higher, and more heat is absorbed every day, less heat is released, and the surface heat accumulates, so it gets hotter every day.

Dog days occur between mild heatstroke and severe heatstroke. This is the hottest, wettest and sultry day of the year. Dog days are also divided into "first volt", "middle volt" and "last volt". When the middle voltage is the hottest in the dog days.

Because the surface humidity increases at the first volt, more heat is absorbed and less heat is released every day, and the heat on the surface layer is accumulated. So, it's hot every day. The weather will be the hottest when the accumulated heat on the ground reaches its peak in the middle of winter.

Mid-range is the second day of the dog days and the hottest period of the year. After entering the middle region, the surface humidity becomes higher, and more heat is absorbed every day, less heat is released, and surface heat is accumulated. Therefore, the weather is getting hotter every day. After entering the middle region, the area heat reached its peak and the weather was the hottest.
