Climate in Brazil
Brazil’s climate varies according to latitude and elevation.
Seasons fall in line with those of Australia (ie the Southern Hemisphere) winter is June-September and summer November-March. On average, the temperature during summer ranges from 25 to 40°C.
There is little seasonal variation near the equator with temperatures averaging 25C.
Warm tropical weather extends north from Rio de Janeiro throughout most of the year.
South of Rio – São Paulo, Santa Catarina, Paraná and Rio Grande do Sul states – the climate is generally of warm summers and cold winters, with occasional snowfall in the far south.
The climate of Brazil varies considerably from the mostly tropical North (the equator traverses the mouth of the Amazon) to temperate zones below the Tropic of Capricorn (23°27' S latitude), which crosses the country at the latitude of the city of São Paulo. Brazil has six climatic regions: equatorial, tropical, semiarid, highland tropical, temperate, and subtropical.
Generally Brazil has moderate rainfall of between 1,000 and 1,500 mm a year, with most of the rain falling in the summer (between December and April) south of the Equator. The Amazon region is notoriously humid, with rainfall generally more than 2,000 mm per year and reaching as high as 3,000 mm in parts of the western Amazon and near Belém.
The Amazon contrasts sharply with the dryness of the semiarid Northeast, where rainfall is scarce and there are severe droughts in cycles averaging seven years. The Northeast is the driest part of the country.
