Which cities in southern China are the hottest in summer?

1. The first one is Nanchang City, Jiangxi Province. Needless to say, the local summer temperature is around 35℃. The reason is that the local terrain is surrounded by mountains on three sides, so the heat can't be emitted, and the temperature is too high in summer. 2. The second is Haikou City, which is located in Hainan Province. Because Hainan Province itself is close to the equator, the temperature will be higher in summer. The local temperature is maintained at around 40℃ in summer. The third is Hangzhou, which has the reputation of paradise on earth, and the local temperature can even reach 40 degrees at noon during the day. The main reason is the local topography. Hangzhou is surrounded by mountains and there is much water in the territory. Heat is hard to dissipate. 4. The fourth is Fuzhou, where the high temperature can last for a long time, and the local average summer temperature reaches 33~37℃. Due to the basin topography, the urban heat island effect is very serious, and the temperature is very high in summer.
