When will it get cold?

After beginning of autumn, it usually takes a month for the weather to get hot and then cool.

Autumn can be more accurately divided into early autumn, mid-autumn festival and late autumn. The early autumn is between beginning of autumn and the heat, and the heat has not completely receded. Under the power of the autumn tiger, the weather is still hot. Mid-Autumn Festival is between the millennium and the autumnal equinox. At this time, the summer heat has completely receded, and the autumn is crisp. Late autumn is between cold dew and early frost. At this time, the weather has turned cold, so pay attention to keep warm.

The hottest time of the year.

The dog days every year are the hottest stage of the year. The dog days this year are from July 16 to August 24, with a total time of ***40 days. The dog days are divided into three days: the beginning, the middle and the end. Starting from the solstice in long summer, the third Geng Day is the beginning of dog days, the fourth Geng Day is the beginning of transit, and the first Geng Day after beginning of autumn is the beginning of doomsday.

Because there are five days between the summer solstice and the beginning of autumn, this year's Mid-Autumn Festival is 20 days. If there are four Geng days, then the Mid-Autumn Festival is 10 days.

Old people in rural areas often say that "Sanjiu is cold and Sanjiu is hot", and Sanjiu is the hottest stage in a year. This year's Zhongfu started on July 26th and ended on August 14. In other words, tomorrow is the last day of Zhongfu. Because the navel is the hottest, there is a saying in the countryside that the navel eats noodles.
