As the saying goes, Rome was not built in a day. Similarly, the heat in summer is not suddenly accumulated, but a gradual process. In May and June of the lunar calendar, we slowly put on spring clothes and short sleeves, which is actually a stage to feel the arrival of summer. Let's briefly analyze how the dog days started.

When does the summer heat of 202 1 start?

It refers to the dog days. Generally speaking, the summer solstice in the third year is the summer solstice. For example, June 2 1 day this year is the summer solstice. Then after three days of Gengzi, Geng Xu and Gengshen, it entered the initial stage on July 1 1, and the whole stage was divided into initial stage, intermediate stage, final stage and emergence stage. According to the law of solar terms, it generally appears in the month from midsummer to beginning of autumn, that is, from mid-July to mid-August. When it comes in and out mainly depends on the date sequence of summer solstice and beginning of autumn Day. You can check the specific date by consulting the calendar.

What are the climatic characteristics?

The overall characteristics of this period are high temperature, low pressure, high humidity and low wind speed, which belongs to the hottest season of the year. In some areas, due to more precipitation, the humidity in the air increases, showing the characteristics of "sauna days", which is sultry and humid. In July and August, the south is usually controlled by the subtropical high. If you eat the airflow, the sky is clear and there is little rain, which is conducive to sunlight radiation, and the ground temperature will rise rapidly. Because the word "Fu" also has a latent meaning, it is intended to tell people that it is not appropriate to be exposed to the sun at this time, but to hide at home for the summer, pay attention to health care, eat more light food and increase nutrition at the same time.
