not exceed 200 meters above sea level. The flat region of the island is almost completely devoid of native vegetation, although in the north region of the island - especially in the Alemoa, Chico de Paula and Saboó neighbourhoods - there are still remnants of mangroves. Before the occupation of the area of the island by 'chácaras' - rural residences, and subsequently by urbanization, there was a vast flooded land covered by mangroves, the native Atlantic Forest, and coastal vegetation. On the city hills one can still find vast areas covered by the native Atlantic Forest, in spite of the existing chácaras and banana harvesting farms in the area. The 'Lagoa da Saudade' (Homesickness Lagoon), a pond located in one of the aforementioned hills, Morro Nova Cintra, was known to host a kind of caiman. The lagoon is also a popular destination among families in the city due to its playgrounds, barbecue kiosks, picnic spots and green areas. The disordered occupation of the hills represents both an environmental as well as a geological risk: the deforestation leads to frequent landslides, mainly from January to March, the traditional rainy season in the region. Most rivers in the island were channeled when engineer Saturnino de Brito designed the system of canals in the city. As examples, we can cite the rivers Dois Rios ("Two Rivers") and Ribeirão dos Soldados ("Soldiers Creek"), which is nowadays referred by santistas as the 'Canal 4' on Avenue Siqueira Campos. Major water courses cut the island in the north, such as the Rio de São Jorge (St. George River), which suffers from the problems of pollution and silting due to the occupation of its banks by slums.

Tropical rainforest climates are typically found near the equator, so Santos featuring this type of climate is an exceptional situation. All months of the year averages more than 60 mm of rainfall during the course of the year. Santos features warm weather throughout the year, though June in Santos is somewhat cooler (and drier) than January. Mean temperatures in the city are around 19 °C during wintertime and around 25
