Climate of Brazil
The climate in Brazil varies considerably from mostly tropical north (the
Temperatures
Temperatures north of the Tropic of Capricorn, especially in low-altitude areas, are high, averaging above 25 °C (77 °F), but not reaching the summer extremes of up to 40 °C (104 °F) in the temperate zones. There is little seasonal variation near the equator other than the rainfall frequency. Average temperatures below the Tropic of Capricorn are mild, ranging from 13 °C (55 °F) to 22 °C (72 °F).
The highest temperature officially registered in Brazil was 44.8 °C (112.6 °F) in Araçuaí, Minas Gerais state, on 19 November 2023.[1] The lowest temperature officially recorded in Brazil was −14 °C (7 °F) in Caçador, Santa Catarina state, on 11 June 1952.[2] However, the summit of Morro da Igreja, a mountain situated in the municipality of Urubici, also in Santa Catarina, recorded a temperature of −17.8 °C (0.0 °F) on 30 June 1996 unofficially.[3] There are frosts south of the Tropic of Capricorn during the winter (June–September).
Although most of Brazil lies in the tropics, more than 60 percent of the country's population live in areas which are cooled either by altitude, sea winds or polar fronts. Some coastal cities of Rio de Janeiro, Recife and Salvador can get extremely hot, with temperatures exceeding 40 °C (104 °F) in heat waves. For example, Rio reached 43.2 °C (110 °F) on 26 December 2012.[4] However, plateau cities such as São Paulo, Brasília and Belo Horizonte have mild climates, and the southern cities of Porto Alegre and Curitiba have mild winters, but while Curitiba has a warm summer due to the average elevation of 934.6 metres (3,066 ft), Porto Alegre has a hot summer, with an average elevation of only 10 metres (33 ft).

The hottest part of Brazil is the northeast, where temperatures of more than 38 °C (100 °F) are frequently recorded during the dry season between May and November. Along the Atlantic coast from Recife to Rio de Janeiro, average temperatures range from 23 to 27 °C (73 to 81 °F). Inland, on higher ground, temperatures are lower, ranging from 19 to 21 °C (66 to 70 °F). South of Rio the seasons are more defined and the range of temperatures significantly wider, with the annual average falling between 17 and 19 °C (63 and 66 °F). The cities of
Precipitation
Precipitation levels vary widely throughout Brazil. Most of Brazil has moderate
High and relatively regular levels of precipitation in the Amazon contrast sharply with the dryness of the semiarid Northeast, where rainfall is highly erratic and there are severe droughts in cycles averaging seven years. The Northeast is the driest part of the country, with erratic rainfall and crops struggling to grow. For example Quixeramobim receives only 499 mm of rain annually.[10] The region also constitutes the hottest part of Brazil, where during the dry season between May and November, temperatures of more than 40 °C (104 °F) are common. However, the sertão, a region of semidesert vegetation used primarily for low-density ranching, turns green when there is rain. Most of the Center-West has 1,500 to 2,000 mm (59 to 79 in) of rain per year, with a pronounced dry season in the middle of the year. For example, Campo Grande has a dry season from June to September and a wet season for the rest of the year.[11][12] In the wet season in cities like Campo Grande, flooding can be a problem because of intense rains that can happen in a short period.[13] Flooding has also been a major issue in cities without a dry season such as Porto Alegre.[14][15][16] The South and areas of the East are without a distinct dry season. Brazil has experienced deadly and devastating droughts in some years.[17][18][19]
Brazil's most intense rain falls around the mouth of the Amazon near the city of Belém, and also in the upper regions of Amazonia where more than 2,000 millimetres (79 in) of rain fall every year. For example, Belém receives 3,084 millimetres (121.4 in) of rainfall annually.[20] The warm weather lets many plants grow here. Most of Brazil has moderate rainfall of between 1,000 and 1,500 millimetres (39 and 59 in) a year, most of it coming between December and April.
Snowfall
Snow has been recorded in Curitiba during several years,[25][26] but has not accumulated significantly since 1975.[27] In 2013, snow hit several municipalities, including Curitiba.[28][29] Snow has also occurred in Porto Alegre, but is very rare.[30][31]
Extreme weather
Because the
Hurricane Catarina is the first and only South Atlantic tropical cyclone to have reached hurricane strength, and impacted Santa Catarina as a Category 2 storm in 2004.[33][34][35] It reached sustained wind speeds of 155 km/h (100 mph) and a pressure of 972 millibars.[36] The hurricane damaged shipyards and several crop fields, and poorer people were affected the most.[37] At least 2,000 people became homeless as a result of the storm.[35]
