Is October a good time to visit Brazil? Yes, October might still be ok for Lencois Maranhenses on the Route of Emotions, although not the best month. Jericoacoara can have strong winds, great time for kitesurfing.
October is one of the best months to be out and about in Rio de Janeiro. Temperatures are between 20-25°C with lovely spring weather. There is very little humidity and a few rainy days. Relatively clear skies, but it can get chilly at night. The beach can be a great option at this time too. Head to Costa Verde, Paraty, Búzios and Ilha Grande.
October is great for Bahia, especially for the southern Bahian beaches. It is the month when you can still see whales. Also great time to see the colonial towns of Minas Gerais.
October is great to visit Pernambuco, Alagoas and Fernando de Noronha.
October is another prime month for wildlife in the Amazon, although it gets very hot (32°C). Activities: fishing for piranha and night walks, as well as 4×4 safaris and kayaking.
October is one of the best months to visit Brazil if you want to have a wildlife experience. If jaguars are your main goal, then October can be a wonderful time. The weather is very hot though (35C). With less water around, more animals congregate around the rivers to drink.
At the Iguazu Falls the temperature are more comfortable and the risk of rain is smaller in October. Although the falls are not that powerful and filled with water, they remain impressive and the rocks peeking through the water can make the falls very spectacular.
It is better to avoid the beaches of Santa Catarina and Rio Grande do Sul due to cold temperatures, as well as the canyons of Aparados da Serra due to rain and low visibility.
