When did it start to get cold?

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".
