Is it hot in August and cold in September?

It's hot in August, neither cold nor hot in September, and it's like spring in October.

August is February in the autumn of the four seasons, also known as Mid-Autumn. In this month, there are two solar terms, namely "autumnal equinox" and "cold dew", and these two solar terms are the time when the temperature is easy to change suddenly, so as to divide the chill in late autumn and the coolness in early autumn. Under this change of solar terms, the sudden drop of temperature is the best embodiment.

In fact, this temperature is determined by "crisp autumn air". During this period, the climate was stable, and the rainfall and humidity were relatively reduced, forming stable climatic conditions, so that the whole September was spent in warm weather.

/kloc-the extended data of Xiaoyangchun in October/October literally means "presenting a warm feeling like spring". October is a mild season, just like spring. At this time, some plants will bloom (twice a year) because the temperature, humidity and temperature are moderate. Why is this weather phenomenon? Because 10 every year, it is already a month with relatively short daylight hours (rural proverbs prove this; "Although the days are long, they will not last for May; Short, short but October. " )

The temperature will be very low in the morning and evening, but as the sun rises, the temperature will rise slowly, and it will feel warm as spring at noon; In contrast, 10 just arrived in beginning of winter and has not yet entered the cold winter month. In addition, the temperature difference between noon and morning and evening is large, which makes people feel like a warm-up after winter.
