Macau (Macao) is a city in the western Pearl River Delta by the South China Sea. It is a special administrative region of China and maintains separate governing and economic systems from those of mainland China. With a population of 696,100 and an area of 32.9 km2 (12.7 sq mi), it is the most densely populated region in the world. Originally a sparsely populated collection of coastal islands the territory has become a major resort city and the top destination for gambling tourism. Its GDP per capita by purchasing power parity is one of the highest in the world and higher than any country in the world in 2014 according to the World Bank.
Macau is on China's southern coast, 60 km (37 mi) west of Hong Kong, on the western side of the Pearl River estuary. It is surrounded by the South China Sea in the east and south, and neighbors the Guangdong city of Zhuhai to the west and north. The territory consists of Macau Peninsula, Taipa, and Coloane. A 1 km2 (0.39 sq mi) parcel of land in neighboring Hengqin island that hosts the University of Macau also falls under the regional government's jurisdiction. The territory's highest point is Coloane Alto, 170.6 metres (560 ft) above sea level.
Macau has a humid subtropical climate, characteristic of southern China. The territory is dual season dominant – summer (May to September) and winter (November to February) are the longest seasons, while spring (March and April) and autumn (October) are relatively brief periods. The summer monsoon brings warm and humid air from the sea, with the most frequent rainfall occurring during the season. Typhoons also occur most often then, bringing significant spikes in rainfall. During the winter, northern winds from the continent bring dry air and much less rainfall.
The mixing of the Chinese and Portuguese cultures and religious traditions for more than four centuries has left Macau with an inimitable collection of holidays, festivals and events. The biggest event of the year is the Macau Grand Prix in November, when the main streets in Macau Peninsula are converted to a racetrack bearing similarities with the Monaco Grand Prix. Other annual events include Macau Arts festival in March, the International Fireworks Display Contest in September, the International Music festival in October and/or November, and the Macau International Marathon in December.
