When did it start to get hot in Wuhan?

Wuhan began to get hot in July. Wuhan is the hottest during Mid-Autumn Festival, from the end of July to the beginning of August. It's hotter in the middle than in the third volt. Although it is often said to be "dog days", it is still the hottest. In the folk, there is a saying that "the cold is in the March 9th and the heat is in the middle". This sentence means that the coldest time of the year is three o'clock, and the hottest time is the "middle volt" among the three volts. After entering the dog days, the temperature is like being in a steamer, which makes people breathless. Especially in the abdomen is the hottest. In the dog days of Wuhan, the subtropical high will strengthen. Under the control of the subtropical high, the downward airflow inside the high will make the weather clear and cloudy, which is conducive to the warming of sunlight and ground radiation, so the weather in Wuhan will be more sultry in July.
