When does it start to get cold in autumn?

Autumn usually begins to get cold after September. But it depends on the region. In the north, the temperature will generally drop in September at the latest, but in the south, it may wait until 165438+ 10.

There is a folk saying that it will be cool for three days in early autumn, but after beginning of autumn, most areas are still dominated by sunny and cloudy weather, and the rainfall weather is not obvious. The temperature can still reach 365,438+0-33℃, the daily average temperature is still high, and the weather is still "sultry". However, due to the large temperature difference between morning and evening and noon, people's somatosensory temperature will be lower than a few days ago in the morning and evening.

Autumn temperature characteristics

Early autumn is still in the heat period, but the heat has not yet come out. The second solar term (summer) came out in autumn, and it was still very hot in early autumn. The so-called "heat is in three volts", according to the calculation method of "three volts", beginning of autumn is often still in the "three volts" period until it is hot in summer.

The "dog days" include four solar terms, namely, slight heat, great heat, beginning of autumn and intense heat. After the intense heat, the heat in early autumn will be over. The climate in autumn is divided into two stages, the early autumn is sultry, and the climate tends to be dry and cool after the Mid-Autumn Festival. It is often after the Millennium that people can feel the obvious coolness of autumn.
