Why is it so hot in Hubei?

In the province of thousands of lakes, the humidity in the air is too high to dissipate heat easily, so as long as it doesn't rain, it won't cool down. And day by day, the temperature is getting higher and higher, even if it rains, it will get hotter and hotter afterwards, and it will remain at about 40 degrees for about half a month. 10 will really start to cool down.
