Summertime in Brazil spans from December through March, and winter occurs from June through September. However, as you travel further north, the temperature and humidity increase. In fact, the Northeast region is so hot that it doesn't experience a winter. In general, September and October are the ideal months for vacationing in Brazil, as you can avoid the peak holiday periods, the chilly southern winter, and the rainy season in the Pantanal. Nevertheless, the best time to visit Brazil will depend on the specific regions you plan to explore.

The Amazon

The Amazon, representing the northern third of the entire country, remains scorching throughout the year and is often characterized as a steamy jungle. This area receives heavy rainfall for around five and a half months, with rain occurring every few hours and constant rainfall leading to floods from January to May. If you wish to embark on a tour of the Brazilian Amazon, the optimal time would be from June to September, before the onset of the rainy seasons. The absolute best time, however, is during July and August.

The Pantanal

The Pantanal region, renowned for its abundant bird and animal species, maintains a consistent temperature year-round. It resembles an African savannah during the peak of summer or an expansive lake in the rainy season. The most intense rainfall occurs between December and March, accompanied by high temperatures and frequent flooding.


The optimal moment to explore the Pantanal and observe the wildlife is throughout the colder months of July until September/October. This period is widely recognized as the arid period.

Rio De Janeiro

The optimal moment to explore Rio is during the summer months, which span from December to March. The wet season brings forth a significant amount of precipitation. Even in the colder months or the period of rainfall, the climate will generally be sunny, although rain typically occurs in vigorous but brief intervals.

December is the peak season and one of the rainiest months, particularly in the Amazon Basin. Anticipate hot and humid conditions as summer arrives. Prices tend to rise due to the Christmas holidays and the warm weather. In January, although the climate may vary across different regions, the average temperature typically remains in the early 80s. It is a favorable time to explore Sao Paulo and Rio as the weather is slightly less humid. February is one of the hottest months in Brazil. The average temperature usually reaches the mid-80s, making it an ideal time to visit the beaches. During this time, crowds and prices soar due to the Rio Carnival, which takes place in February or early March, coinciding with the beginning of Lent. In March, expect warm and humid weather nationwide as the peak season begins to fade. Be prepared for occasional summer showers. The increased water volume during this time provides an unforgettable experience when visiting the Brazilian side of the Iguazu Falls.


April – July

In April, while the weather along the coastline remains predominantly warm and dry, temperatures start dropping as you head south, indicating the gradual arrival of winter. May marks the beginning of the low season in Brazil. The average temperature is usually around the early 70s. It is typically the last month to travel to the southern part of the country before winter fully sets in. June brings clear skies and pleasant temperatures, with an average daytime temperature of 71°F. It is one of the coolest and driest months of the year, making June and the following months an ideal time to embark on a cruise through the Amazon rainforest. As you move further up and south, temperatures become colder, and several resorts close for the winter season.

August – November

August is one of the optimal periods to explore Brazil due to the pleasant spring temperatures and absence of precipitation. This month can be particularly hectic owing to the influx of tourists from the Northern Hemisphere. Temperatures continue to escalate in September, along with the humidity. Anticipate overcast skies and rainfall towards the conclusion of the month in Rio. September and October are commonly regarded as the prime months to discover Brazil, particularly for lion observation in the Pantanal. October symbolizes a period of transition in all the diverse climatic regions in the nation. November witnesses an upsurge in temperatures and precipitation levels throughout the country. It is a moderately damp and mild month with the mean temperature hovering around the mid-70s and minimal variation between daytime and nighttime temperatures.
