When did Changsha start to get hot?

Changsha began to get hot in May, but it was only a few days in May.

In June, the weather is hot. In July and August, it is normal to have hot days above 35 degrees. In September, autumn tigers may kill again, and it will be hot for a few days. Why is Changsha so hot in summer? In meteorological sense, when the daily maximum temperature reaches or exceeds 35.0℃, it is generally called high temperature. Due to the geographical location of Changsha, it is just shrouded by subtropical high, and downdraft prevails. In most areas, the weather is sunny, rainy and windy. When it is entrenched for a long time, there will be a serious drought. Changsha, Wuhan, Nanjing and other southern cities often have "stove" weather in summer, and the chief culprit is this subtropical high.
