What's the change in the weather in early autumn?

1. After beginning of autumn, the weather will continue to be hot, but beginning of autumn indicates that the hot summer is coming to an end and autumn is coming, which also means that the vegetation is beginning to bear fruit and the harvest season is coming.

The ancients regarded beginning of autumn as an important moment at the turn of summer and autumn, and always attached great importance to this solar term. After autumn, with the tropical ocean air retreating into the sea, the air over many areas is gradually controlled by the denatured Siberian air mass, forming the most pleasant autumn weather all year round.

3. However, because it is basically controlled by a single air mass, the wind direction changes greatly in the morning and evening, and the northwest wind is often blown at night and the south wind is blown during the day.

4. Therefore, after beginning of autumn, it will be finished or the weather will gradually turn cold, and the temperature difference between morning and evening will be large. Sometimes it feels cold to wear long sleeves in the morning, but it still feels hot to wear short sleeves at noon. This is why there is a folk saying "autumn tiger", which usually occurs at the turn of August and September and lasts about 7- 15 days.
