Climate - Zhanjiang (China)

The climate of Zhanjiang is subtropical, with very mild winters and hot, humid and rainy summers. The rains are abundant from May to September.
The city is located in southern China, at 21 degrees north latitude, in the southwest of Guangdong province, in a bay on the South China Sea. We are in the northern part of the Leizhou (or Luichow) peninsula, which in the southern part is 20 km (12 mi) away from the island of Hainan.
Winter, from December to February, is very mild, however, the north-east monsoon brings cloudy days, during which there are some drizzles, or fog can form. Sometimes, cold and windy days can occur, with highs around 10 °C (50 °F) or even below. In January 2016, the temperature dropped to 3 °C (37 °F), with a maximum of 6 °C (43 °F).
Guangdong can be hit by typhoons, the tropical cyclones of Southeast Asia.

The area most at risk is the coastal one, since it can receive the strongest winds, as well as storm surges.
