Macau is located in the southern part of China's Guangdong Province, on the tip of the peninsula formed by the Zhujiang (Pearl River) estuary on the east and the Xijiang (West River) on the west. Macau is situated sixty kilometers west of Hong Kong and 145 kilometers southwest of Guangzhou, the capital of Guangdong Province. It is immediately adjacent to the Zhuhai Special Economic Zone.

The region comprises the Macau Peninsula and the islands of Taipa and Coloane. Macau was once an island but gradually a connecting sandbar turned into a narrow isthmus. Land reclamation in the 17th century made Macau into a peninsula, and a barrier gate was built to mark the separation between the peninsula and the mainland. Pre-colonial records show that Macau totaled only 2.78 km² but began to increase as a result of Portuguese settlement. Land growth has accelerated since the last quarter of the 10th century, from 15 square kilometers in 1972 to 16.1 square kilometers in 1983 to 21.3 square kilometers in 1994. Macau's size has gradually increased as result of continued land reclamation, especially on Taipa and Coloane. In 2000, the total land area was approximately 23.6 km². There is a 0.34-kilometer-long border between Macau and mainland China and a forty-kilometer-long coastline.

Topography

Terrain: generally flat
Elevation extremes:
lowest point: South China Sea 0 m
highest point: Coloane Alto 174 m

Macau has generally flat terrain resulting from extensive land reclamation, but numerous steep hills mark the original natural land mass. The modern high-rise skyline of Macau obscures much of the hilly landscape. The Macau skyline both defines and obscures its topography.

Climate

Subtropical; marine with cool winters, warm summers

The climate is subtropical and is hot and humid, with an average year-round temperature of 25°C and temperatures exceeding 30°C from June to September. Temperatures rarely fall below 14°C (the average for January and February). There is about 2,030 millimeters of rainfall annually. Macau is exposed to tropical storms originating from the southern Pacific Ocean during the summer. Major destruction occurred in September 1874, when a devastating typhoon hit Macau and high seas swept across the low-lying area of the peninsula.

Natural Resources

Negligible. In the past, large amounts of granite were extracted from Macau's hills for use as building material.

Land Use

No arable land, pastures, forest, or woodland. Because of this deficiency, Macau's people traditionally have looked to the sea for their livelihood.

arable land: 0%
permanent crops: 2%
permanent pastures: 0%
forests and woodland: 0%
other: 98% (1998 est.)

Environmental Factors

Dense urban environment.

Geography - note: essentially urban; one causeway and two bridges connect the two islands of Coloane and Taipa to the peninsula on mainland
