What weather changes do the July Fires refer to?

The weather in July is getting cooler.

This means that at dusk in the seventh month of the lunar calendar, if a big Mars appears in the western sky, it means that the heat of summer begins to subside; by September, the weather will be cold and thick clothes will be needed.

Actually, the "July" in "July Fire" refers to August and September. The reason why there is misunderstanding is because people use different chronological systems.

July Solar Terms

Small Heat

The sun reaches 105 degrees of ecliptic longitude, which is celebrated every year from July 6 to 8 in the Gregorian calendar. Shu means hot, Xiaoshu means mild heat, not very hot yet. It means that the weather is starting to be hot, but it is not yet at its hottest. Although Minor Heat is not the hottest time of the year, it is immediately followed by Great Heat, which is the hottest season of the year. There is a folk saying that "Minor Heat and Great Heat are steaming at the top and boiling at the bottom."

Many places in my country have entered the season with the most thunderstorms since Xiaoshu. Monsoon climate is the main characteristic of my country's climate. In summer, affected by warm and humid airflow from the ocean, many places in my country are hot, humid and rainy. Although the sun is strong, hot, humid and rainy during this season, for crops, the rain and heat at the same time are conducive to the growth.

Judging from the seasonal distribution of precipitation, my country's precipitation is mainly concentrated in summer, when the southeast monsoon prevails. In the high-temperature season, crops grow vigorously and require a lot of water. Summer is the season with the most and most concentrated precipitation in my country. The high-temperature period coincides with the rainy period. A good combination of water and heat is very beneficial to the growth of crops. Since precipitation in my country is mainly caused by water vapor brought from the ocean by the southeast monsoon, precipitation gradually decreases from the southeast coast to the northwest inland due to the influence of the summer monsoon.
