Geography

Recife, seen from the International Space Station.

Due to the city's proximity to the equator, Recife weather is generally warm. Recife has a number of islands, rivers, waterways and bridges that crisscross the city. Recife is located amidst tropical forests which are distinguished by high rainfall levels resulting in poor soil quality as the rainfall washes away the nutrients. There is an absence of extreme temperatures and a cool breeze due to the trade winds from the Atlantic Ocean.

Recife has a tropical forest. Rainforests are characterized by high rainfall, with definitions setting minimum normal annual rainfall between 2,000 millimetres (79 in) and 1,700 millimetres (67 in). The soil can be poor because high rainfall tends to leach out soluble nutrients. There are several common characteristics of tropical rainforest trees. The city of Recife is formed by three islands (Recife, Santo Antônio, and Boa Vista). Between the islands are the rivers Beberibe and Capibaribe.
