Will it be hot until September?

Generally speaking, September will not be too hot. For example, in the north of 20 17, the end time of the hottest dog days is August 20 17, the solar term in beginning of autumn is August 7, and the solar term in summer is August 23. In other words, the hot weather after August 7 is autumn tiger. The autumn tiger of 20 17 is expected to end in late August. Therefore, the weather will not be too hot in September, and the continuous high temperature weather will decrease, and the weather will gradually turn cold and enter the autumn climate.

20 17 at the end of September, the weather is no longer hot. Because the autumn tiger has passed, the solar term has passed, and the autumnal equinox on September 23, 20 17 has also passed. In the autumn equinox, most parts of China have entered a cool autumn. The cold air from the south meets the gradually decaying warm and humid air, which causes repeated precipitation and the temperature drops again and again. As people often say, it's time for an autumn rain and a cold, but the daily precipitation after the autumnal equinox will not be very large.

September will enter the Millennium solar term, and the summer monsoon will gradually be replaced by the winter monsoon, and the cold air will turn to attack and the warm air will gradually retreat. Cold air going south in batches will often bring a certain range of cooling. People like to use the proverb "it's cold in the autumn night in the white dew" to describe the situation that the temperature drops rapidly. At this time, people will obviously feel that the hot summer has passed and the cool autumn has arrived. Because the temperature is still more than 30 degrees during the day, but it drops to more than 20 degrees at night, and the temperature difference between them is 10 degrees.
