When is the coldest in the south and which month is the coldest in the south?

1, in most parts of the south, the coldest time is in the late June of 1, when it just entered the great cold, so the great cold is greater than the slight cold.

2. In northern China, the coldest time of the year is in the middle of 1 month, that is, 65438+1October to 10-20, and the annual slight cold is around 65438+1October 5-20, so the north is more or less colder than the severe cold; In addition, nine cold days means that there are three or nine days in the coldest time of the year. It takes nine days from the winter solstice to three or nine days, with 18 days in the middle and 15 days from the winter solstice. The weather of three or nine days is just in the slight cold solar term, so there is a saying that the slight cold solar term is the coldest.
