The weather changes in early winter.

Starting from beginning of winter, the temperature in all parts of China will drop faster and faster, and the temperature drop can be obviously felt.

In southern China, sunny, warm and comfortable spring weather often appears from beginning of winter to Xiaoxue. There is a folk saying that "August is warm and September is warm, and October has spring". Generally, it is not very cold in early winter in the south, but with the passage of time, cold air frequently goes south and the temperature gradually drops. In the northern part of South China in early winter, the temperature will rise rapidly even if the cold wind sweeps. When there is no wind on a sunny day, it is often said that October is sunny and there is no wind and warmth.

In the area near the north of Huaihe River in Qinling Mountains, cold air frequently appears, and cooling has become the normal state of this season. In the northeast and northwest regions, it is already a scene of heavy snow, especially in the northeast Heilongjiang region, which is extremely cold and has entered the winter before the arrival of beginning of winter. The red and yellow scene in northwest autumn has not completely faded, but the snow has already fallen.
