The first day of Summer Ambush 2023 is July 11th.
From this day onwards, it officially enters the summer ambush, also known as the three ambush days, and July 11th - July 20th is the first ambush. "Summer solstice three g counting the first ambush", meaning from the summer solstice to count to the third g day is the first ambush of the day. Four g day to the fifth g day for the middle ambush, the first g day after the fall to the second g day for the end of the ambush, which is known as the "three ambush".
The three ambushes are the hottest period of the year, due to the progressively shorter nights and longer days, and the near-direct sunlight. The first ambush occurs on the third g day after the summer solstice and lasts for 10 days, with the time of day varying from year to year. First ambush: July 11, 2023 - July 20, 2023, *** 10 days; Middle ambush: July 21, 2023 - August 9, 2023, *** 20 days; Last ambush: August 10, 2023 - August 19, 2023, *** 10 days .
After entering the ambush, the humidity of the ground becomes higher, more heat is absorbed by the ground and less heat is emitted every day, and the heat in the surface layer accumulates, so it gets hotter day by day. The weather is hottest when it enters the middle of the month, when the heat accumulated on the ground reaches its maximum value.

The Eastern Han Dynasty - Ban Gu, "Han Shu - Suburban Sacrifice Zhi Note", added: "Voltaic, that is, the yin will rise, forced by the remnant of the sun and did not get to rise. Therefore, it is a hidden ambush, hence the name ambush day."
