Brazil : climate and when to go to Rio de janeiro
The Brazil has a predominantly tropical but temperate climate in the south. The seaside extends over many miles from north to south, so it is normal to have several climates. We propose four climates for the cities of Belem, Fortaleza, Recife and Rio de Janeiro , which are therefore beach towns with beaches known in Brazil.
The summer months are reversed compared to France and warmer (December, January and February). Temperatures range from 86°F to 95°F. The winter months are more temperate from July to September with 59°F to 77°F in the southeast.In the north, the tropical climate is hot and humid with two seasons, one rainy from January to May and another dry from June to October. The Northeast is a temperate climate all year round ranging from 72°F to 82°F. In the extreme south, the winter is cold and the snow can fall.
In any case, Brazil is a beach destination and the Brazilians tanned bodies on the beach of Copacabana in Rio de Janeiro really proves it!

Weather uncertainties 2025 to go to Rio De Janeiro ?
When traveling in the tropics as a seaside, rain is not welcome. If you see this indicator, with possible storms, that does not mean that it will rain all day long. When we observe the local rainfall, it is either really zero or very weak. Meteorologists prefer to be pessimistic. So observe below, the skies photographed during a week announced stormy in Asia. It did not rain once. I invite you to integrate this parameter before going to Rio De Janeiro for a good trip to the sun!
