July 1 day, confirmed in dog days. Will it be very hot this year?

It's bound to be hot. The hot weather in dog days can't be ignored, especially because it spans two solar terms, namely, the great summer heat and the slight summer heat. Its humid and sultry temperature prompted the ancients to prescribe the right medicine, in line with the laws of solar terms. Faced with the rising temperature, many health problems followed, and heatstroke prevention and dampness prevention were the most important things for the ancients.

Is it hot in dog days this year? This year's dog days began in July 16 of the Gregorian calendar, which is June 18 of the lunar calendar. According to the ancients, this year's dog days are "mother volts". What is a mother volt? The female volt is relative to the male volt. There are men and women in dog days every year. According to the lunar calendar, male volts corresponds to "Yang", which is singular. The mother volt corresponds to "Yin", that is, even number. In this way, this year's dog days are "mother volts".

Even if the temperature is not high in dog days, because the surface temperature has reached saturation and the temperature difference between day and night is small, there is no wind at this time, and it will still be sultry, but it will be cooler than in previous years. Everyone should be prepared to prevent heatstroke and drink mung bean soup from time to time.

If it is not hot in the dog days, there will be no bumper harvest. It's not hot in dog days, and the grain harvest is not good after autumn. Because crops need sunlight to grow. Take corn as an example. A pimple can grow in three days in sunny conditions. Today's corn has just emerged, and it needs sunshine and rain at the seedling stage. If more fertilizer is applied at this time, the corn will grow quickly.

If the weather turns cold, it means that there are more cloudy days or rainy days in the dog days, then there will be fewer sunshine days, and more rain will easily lead to waterlogging and tree death, and eventually reduce production during harvesting. It seems that the demand for temperature between crops and humans is very different.

Generally speaking, if the average temperature in July is below 30℃, the rainfall in autumn will be less than 95mm；; When the average temperature in July is above 30℃, the autumn rainfall will be higher than 95mm.

In this way, there are advantages and disadvantages, and everything is regular. People long for the coolness in dog days, but crops need to rely on the normal operation of the weather to ensure the harvest. If the weather contrast is large, some unexpected situations may occur this year, so we should follow the laws of nature.
