Climate in Macau

Macau has a humid subtropical climate (Köppen Cwa), with average relative humidity between 75% and 90%. Similar to much of South China, seasonal climate is greatly influenced by the monsoons, and differences in temperature and humidity between summer and winter are noticeable, though not as great as inland China. The average annual temperature of Macau is 22.7 °C (72.9 °F). July is the warmest month, with average temperature being 28.9 °C (84.0 °F). The coolest month is January, with a mean temperature of 16.0 °C (60.8 °F).

Located on China's southern coast, Macau has ample rainfall, with average annual precipitation being 2,120 millimetres (83 in). However, winter is mostly dry due to the influence of the vast Siberian High affecting much of East Asia. Autumn in Macau, from October to November, is sunny and still pleasantly warm with low humidity. Winter (December to early March) is generally mild with temperature above 13°C most of the time, although it could also drop to below 8°C at times. Humidity starts to increase from late March. Summer is very warm to hot (often rising above 30 °C (86 °F) at daytime). The hot weather is often followed by heavy rain, thunderstorms and occasional typhoons
