Because it is located in the southeast coast of the Asian continent and is deeply influenced by the monsoon, it has formed a remarkable feature of seasonal variation of weather in the middle of the year.

The cooling effect of the mainland surface in winter and the heating effect in summer make the climate of Hong Kong distinct in four seasons and quite different. So there is heat in summer and sudden cooling in winter. At the same time, due to the influence of tropical and temperate weather, the weather in Hong Kong changes differently every day. The average temperature in the coldest month of 65438+ 10 is 15.2 12 degrees, and the average temperature in July in the hottest month is 27.9 12 degrees, which is above annual range 12.7 degrees.

Hong Kong has obvious dry and wet seasons. In addition, during most of the year, the weather in Hong Kong may change dramatically.

Severe weather changes, usually caused by the passage of tropical cyclones.
