Why is it more than June, but it's not hot in Zhejiang?

Not far from the seaside, because seawater absorbs heat and dissipates heat slower than land, and it has experienced another winter. In summer, when the sea water just begins to absorb heat, the air at sea will be cooler than the air on land, and with the help of the southeast wind in June, the air at sea will float to land, so naturally it will not be so hot.
