What does the sentence "It's too hot in summer and cold in summer" mean?

The folk proverb "It is very hot in summer, but it is very cold in summer" means that if it is very hot in summer, it will be even colder this autumn.

Little summer is the eleventh solar term among the twenty-four solar terms of the lunar calendar and the fifth solar term in summer, which marks the official start of the last month of summer. When the sun reaches longitude 105 degrees, it is called the solar term.

Summer heat, which means hot, is a little hot, not very hot. It means that the weather is getting hotter, but it is not the hottest, and most parts of the country are basically in line with it. Crops all over the country have entered a vigorous growth period, and it is necessary to strengthen field management.

The summer solar term is just around the Mid-Autumn Festival in the dog days, which is the hottest period of the year, with the highest temperature and the fastest growth of crops. At the same time, various meteorological disasters such as drought, waterlogging and wind disasters are also the most frequent in many areas.
