Introduction to Macau Climate
Located to the west of the estuary of the Pearl River (Zhujiang), between mainland China and the South China Sea, Macau weather is influenced by the cold northeast monsoon from China's mainland and the southeast and southwest monsoons from the ocean by turns and therefore Macau's climate has the features of both continent and ocean climates.

Macau's spring is from March to April when the southeast winds bring warm and humidity to this area. Despite of a few periods of fog and rain, the days filled with pleasant sunshine are typically accompanied with mild nighttime temperatures. Travelers should be sure to pack sweatshirts, light jackets and an umbrella.

Beginning in May, Macau's summer season usually lasts through September. The extreme high temperatures and heavy humidity bring many rainstorms, thunderstorms and even disastrous waterspouts. However, it is the good time for swimming at the beaches like Hac Sa Beach and Cheoc Van Beach. The months from July to September might be filled with frequent cyclones. Travelers should attempt to avoid the typhoon season and stay at home when storms and cyclones come. T-shirt and shorts are suitable for the hot and humid days and raingear is an additional must.

After the hard summer, the intense southwest winds disappear and the winds from the northern continent bring this region a mild autumn with cool days from October to December. This, typically, is the most comfortable time of year for traveling. For this period, sweaters and jackets are a good idea for heading out after hours.

Starting from middle to later December, temperatures gradually drop, as the winter in Macau begins. January to February is the coldest period in Macau when the cold air from Siberia going down via the northern continent and arriving at the peninsular. Sometimes the temperature plummets to 10 C (50 F) below zero. Woolen clothes and overcoats are necessary to keep warm for travelers wanting to spend this period in the city.
