When is September on the calendar? Is it autumn?

Autumn is one of the four seasons. In China, traditionally, "beginning of autumn" in the 24 solar terms is taken as the starting point of autumn. Entering autumn means that rainfall and humidity tend to decrease or decrease. In nature, everything grows from lush to mature from August 23rd to165438+1October 22nd.

Climatic characteristics:

Beginning of autumn doesn't mean that the hot summer will be over. beginning of autumn is still in the heat period, and the heat will not come out until the second solar term in autumn, and the weather is 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 the summer heat, so the weather is still very hot in early autumn, and it will generally cool after the Millennium solar terms.

The watershed of summer heat is in autumn, not at the turn of summer and autumn. 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.
