Lunar calendar: June 19th.

Summer is one of the twenty-four solar terms of the lunar calendar, and the sun is located in the yellow meridian 120. In the hot summer, Han people have the custom of drinking tea, drying ginger and burning incense. "Twenty-four solar terms" said: "Summer is in the middle of June. Summer, summer, size, small at the beginning of the month, big in the month, and still hot today. "

Its climatic characteristics are: "Dou refers to C as a great summer heat, and the weather in Sri Lanka is stronger than a small summer heat, so it is called a great summer heat." 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.

At this time, before and after the mid-autumn period, most parts of China are the hottest period in a year, and the growth rate of heat-loving crops is also the fastest. The working people of the Han nationality divide the summer heat into three periods: "One period is rotten grass like fireflies; Second, wait for the soil to moisten and cool off the heat; It will be fine when it rains. " There are about 2000 species of fireflies in the world, which are divided into aquatic and terrestrial species. Terrestrial fireflies lay eggs on hay.

In the summer heat, fireflies break out of their shells, so the ancients thought fireflies were made of rotten grass; The second weather is that the weather becomes sultry and the land is wet. The third kind of weather is frequent thunderstorm, which weakens the heat and humidity, and the weather begins to transition to beginning of autumn.

Summer solar terms are in the "three volts", which is the period with the most sunshine and the highest temperature in China. Most parts of the country are dry and lack of rain, and the temperature in many areas is above 35 degrees, so the so-called "three stoves" are also the most prosperous.

In the western part of South China, although the high temperature appears most frequently, the rain is the most abundant and the thunderstorm is the most common, which is the season with the most thunderstorms. There is a proverb here that says, "East flash can't go down, and west flash can't go." It means that in the summer afternoon, if there is lightning in the east, the rain will not come here. If lightning is in the west, the rain will come soon, and it's too late to hide.

According to whether it is hot or not, there are many agricultural proverbs to predict the weather in the later period: for example, in the short term, there will be a "great summer, and the fields will rest;" It is cool in summer and the pond is full of water "; Mid-term means "great heat, cool after autumn"; Long-term predictions include "the heat is unbearable, and there will be no frost for four months", "the heat is not hot, the winter is not cold" and "the heat is not hot, and the winter will rot".
