Havana is the capital city, largest city, province, major port, and leading commercial centre of Cuba. The city proper has a population of 2.1 million inhabitants, and it spans a total of 728.26 km2 (281.18 sq mi) – making it the largest city by area, the most populous city, and the third largest metropolitan area in the Caribbean region. The city extends mostly westward and southward from the bay, which is entered through a narrow inlet and which divides into three main harbours: Marimelena, Guanabacoa and Atarés. The sluggish Almendares River traverses the city from south to north, entering the Straits of Florida a few miles west of the bay.
Havana, like much of Cuba, has a tropical climate that is tempered by the island's position in the belt of the trade winds and by the warm offshore currents. Under the Köppen climate classification, Havana has a tropical savanna climate. Average temperatures range from 22 °C (72 °F) in January and February to 28 °C (82 °F) in August. The temperature seldom drops below 10 °C (50 °F). The lowest temperature was 1 °C (34 °F) in Santiago de Las Vegas, Boyeros. The lowest recorded temperature in Cuba was 32 °F (0 °C) in Bainoa, Mayabeque Province (before 2011 the eastern part of Havana province). Rainfall is heaviest in June and October and lightest from December through April, averaging 1,200 mm (47 in) annually. Hurricanes occasionally strike the island, but they ordinarily hit the south coast, and damage in Havana has been less than elsewhere in the country.
