Brazil's climate varies greatly throughout the 5 regions and 26 states. However, Brazil is considered a year-round destination rarely reaching below 20°C (68°F) temperatures, apart from mountainous cities and southern regions.
With an area of 8,514,876 km², Brazil is the biggest country in South America and the 5th largest country in the world, just behind China, Russia, United States and Canada. Due to the immensity of the Brazilian territory, several types of climates are identified, and many areas are characterized by various weather conditions, depending on their latitude.
Brazil is part of the Southern Hemisphere, so the seasons are at the opposite to the Northern Hemisphere. This means that when it’s winter in places located in the north of the equator, such as the United States, Canada and Europe, it’s summer in Brazil as well as in all places located in the south of the equator.
These are the dates of each of the seasons in Brazil (They may vary by one day depending on the year):
Summer: December 22nd to March 20th.
Fall/Autumn: March 20th to June 21st.
Winter: June 21st to September 23rd.
Spring: September 23rd to December 22nd.
Brazil comprises 26 states and 1 federal district. and it’s divided into five regions. Each of these regions have their own characteristics of climate and weather. Bellow you will see the list of regions and the states that are included in each one of them:
South (Rio Grande do Sul, Santa Catarina and Parana)
Southeast (São Paulo, Rio de Janeiro, Minas Gerais and Espirito Santos)
Central-West ( Mato Grosso do Sul, Mato Grosso, Goias and the Federal District)
Northeast (Alagoas, Bahia, Ceara, Maranhão, Paraiba, Pernambuco, Piaui, Rio Grande do Norte, Sergipe)
North (Acre, Amapa, Amazonas, Para, Rondonia, Roraima, Tocantins)
The temperature is high across the entire country. South, Southeast and Central-West regions record their highest temperature values in the year. The temperature around the country is usually above 30ºC (86ºF) during the day, and there might even be temperature spikes above 40ºC (104º).
In the North and Northeast regions, temperatures are more homogeneous, they vary from around 25ºC (72ºF) to 32ºC (89ºF).
In Southeast and part of the Center-West Region of Brazil, temperatures become milder due to the entry of cold air masses, the temperatures oscillate between 20ºC and 28ºC (65ºF and 82 ºC). In the South, the temperatures will eventually drop below 20ºC (65ºC).
In the Southeast - where Rio de Janeiro and Sao Paulo are located - the weather is mild, reaching values from 18ºC to 25ºC (from 65ºF to 77ºF). The North and Northeast regions are not very affected by winter and the temperature remains above 25ºC during the day in most of the states and cities. The temperature drops considerably in the South of Brazil, and some mountainous cities might even record temperatures below zero on the coldest days.
Temperatures gradually increase in the South, Southeast and Center-West regions. In Central Brazil, maximum temperatures can reach very high values due to the strong solar radiation and the greater frequency of days with clear skies. However, during this period, there may still be incursions of intense cold air masses that can cause a sharp decline in temperature in the center-south of the country.
