Brazil in October: Calm Before the Rains


October is the beginning of the rainy season in Brazil and has cool, dry weather. This is the perfect time to venture into the Amazon rainforests where the steamy jungle heat and humidity are at their lowest and wildlife are at their most active. Since Brazil in October is shoulder season, the beaches aren't beaming with tourists, and the mountain trails and other attractions have sparse foot traffic. Furthermore, you can find excellent deals on accommodations, flights, and tours to Brazil

Why visit Brazil in October

Brazilian cuisine

October is a shoulder tourist month in Brazil. The beaches aren’t too crowded, and for nature lovers, traveling to the Amazon introduces diverse wildlife species that are easy to spot during this time of the year.

  • Visit the Ilha Grande: Located an hour from Rio, the Ilha Grande is a forest-covered island with superb beaches and no cars. On your trip to the Ilha Grande, take cash because most places don’t accept cards, wear comfortable shoes, and carry along insect repellent. 
  • The rainforest at its best: Before the humidity and heat become uncomfortable, October is the best month for visiting the Amazon rainforests. The inland city of Manaus is a cultured and sophisticated metropolis from which you can embark on riverboat voyages deep into the jungle along big rivers and narrow waterways.
  • Octoberfest: In the south of Brazil, the town of Blumenau’s German heritage comes to the fore in its Octoberfest celebrations with plenty of beer, bread, and oom-pa-pa bands.
  • Wildlife spotting in the Pantanal: The end of the dry season is perfect for visiting the vast Pantanal region, the world’s largest submerged grassland, where spotting wildlife is at its easiest before the rains bring fresh growth for the critters to hide in.

Where to go and what to do

Brazil's weather in October makes travel pleasant, especially in the cities. Rio de Janeiro bustles with street life and you can combine days at the beach with sightseeing excursions to places such as the Green Coast and the Encontro das Águas (the Meeting of the Waters) where the dark jungle waters of the Rio Negro meet the coffee-colored Rio Solimões.

The thunderous Iguazu Falls on the Brazil-Argentina border are an uncrowded spectacle in October and in the Chapada Diamantina National Park, in Brazil’s northeast, you’ll find towering waterfalls, quartz caves, and colonial mining towns.

If you need a break from the frenzy of Rio de Janeiro, the city has the largest botanical garden in South America where you can see 6,000 species of plants and stroll the 750 meter-long Avenue of Royal Palms. In the waters off Santa Catarina, you can go whale-watching or take advantage of the October winds to go windsurfing or kite-boarding.

Although the locals might think the temperature in Brazil in October is on the chilly side, it is still perfect for swimming at the Copacabana, catching a tan at Ipanema, or sipping cool drinks as you watch the world go by on a city street or a rainforest road.
