Macau exhibits a humid subtropical type of climate (Köppen climate classification Cwa) with hot and humid summers and cold and dry winters. It is a special administrative region of the People's Republic of China with territorial autonomy, which lies on China's southern coast on the west side of the Pearl River estuary in East Asia.
Macau's location in the tropical latitudes, slightly south of the Tropic of Cancer in the Northern Hemisphere, the monsoon, and its nearness to large bodies of water, dramatically affects its climate.

Macau, the most densely populated region in the world, consists of the Macau Peninsula, and the Taipa and Coloane islands that are connected by landfill. The terrain is mostly flat apart from some steep hills as the region is devoid of arable land, woodlands, forests, or pastures.
Macau has roughly 25 miles of coastline as land reclamation transformed the original island into a peninsula; its small area of 11.8 square miles sees some of the tallest buildings in the world. With a dense population to support, the climate poses a singular influence on the architecture of the buildings, and the region is home to numerous skyscrapers.

Macau receives an average of 1774 hours of sunshine over the year with an average annual temperature of 22.6°C (72.7°F), and abundant rainfall to the tune of 2057.4mm (81") throughout the year.

Summers are hot, muggy and damp as average high temperatures rise to 31.7°C (89.1°F) during the peak month of July with many days above 35°C (95°F). May to August receives up to 80% of the yearly rainfall and is prone to thunderstorms and typhoons.

Winters are mild and dry due to the effect of the Siberian High on East Asia. Average low temperatures are at 12.2°C (54°F) during the coldest month of January, and temperatures rarely drop below 8.9°C (48°F).
Snow and frost are unknown, as Macau is a low altitude coastal region with prominently flat topography.

Spring and autumn are pleasant as the temperatures are comfortable without the heat and wetness of summer.

The monsoon significantly influences the climate during the summer months with high humidity and ample rain. Summers are prone to tropical storms that account for heavy rain, sometimes receiving the monthly rain average in a few days. Macau's low-level coastal location is susceptible to tropical cyclones, which regularly churn the South China Sea. Lack of mountains in the region provides no barriers to the cold winds from the north in winter.
