What is the weather like in Brazil in December?

If you’re planning a trip to Brazil in December, you’re in for a hot and humid experience, especially in the south and central parts of the country. December marks the start of summer, and while that means longer days and lively beach scenes, it also brings rain, especially in cities like Rio de Janeiro and São Paulo. Temperatures often reach the 80s to 90s°F (27°C to 35°C), with tropical storms arriving in the afternoons.

Expect high humidity and sudden downpours, particularly in the Amazon and Pantanal regions. Roads can get muddy and river levels rise, which might affect travel in remote areas. Coastal areas, however, stay busy, with Brazilians kicking off their summer vacations and gearing up for New Year’s celebrations.

But if you want energy, color, and festive vibes, December delivers. Book ahead, bring light clothes and rain protection, and get ready for a sweaty but unforgettable start to summer.

In December, locals know that Rio gets packed and pricey, so if you're not into crowds, head to the coast of Santa Catarina. Places like Praia do Rosa have that summer buzz without the chaos, and you’ll find way better seafood.

Is December a good time to visit Brazil? 

December in Brazil isn’t just summer, it’s samba season. The country turns the volume up with sun, parties, and serious beach energy. Planning Brazil trips this time of year? Expect packed coastlines, overflowing caipirinhas, and fireworks lighting up the sky from the best beaches in Brazil.

This is when Rio hits its stride, Salvador starts to sizzle, and São Paulo empties as locals flee to the coast. It’s also the run-up to Réveillon (New Year’s Eve), when millions dress in white and dance into the sea at midnight. If you’re after culture, heat, and a taste of chaos, in the best way, December delivers.

But it’s not all coconut water and sunshine. It’s high season, which means prices spike and popular spots fill fast. Rain shows up too, especially in the Amazon and the south. And if you're hoping for peace and quiet, forget it; the best cities in Brazil are in party mode.

Still, if you can handle the crowds and the occasional tropical downpour, December is an unforgettable time to be here. Just book early, pack light, and follow the music, it usually leads somewhere fun.

Why December is a good time to visit:

  • Beach weather in full swing: The weather in Brazil in December is hot and summery, perfect for hitting iconic stretches like Copacabana, Jericoacoara, or Praia do Forte. Pack sunscreen, not sweaters.
  • Festive energy everywhere: Brazilians don’t do December quietly. From fireworks in Rio to Afro-Brazilian drumming in Salvador, cities come alive with music, dancing, and all-night celebrations.
  • Early December bargains: Before Christmas week kicks off, flights and hotels are still (relatively) reasonable. It’s a smart window if you want summer vibes without vacation prices.
  • Nature at its loudest: Rainforests in places like the Amazon and Iguaçu Falls roar back to life. Trails can be muddy, but the wildlife is active and the scenery is dramatic.
  • Coastal escapes beyond Rio: While Rio gets packed, locals head to lesser-known gems like Itacaré, Ilha Grande, and Pipa. You’ll still get the postcard beaches, just with fewer people and more space to stretch out.

What about crowds and costs?

In Brazil, December is a vibrant yet bustling time due to the vacation season and the onset of summer vacations. This period typically sees an influx of tourists, particularly in hotspots like Rio de Janeiro and São Paulo, as well as coastal destinations. As such, attractions and beaches often buzz with activity, and accommodations tend to fill up quickly. It's wise to plan your trip well in advance and secure reservations early to navigate the crowds.

On the financial side, December's popularity can drive up prices, especially for flights and hotels. This is more pronounced in sought-after areas. However, with early planning and flexibility in travel dates, you might still snag some good deals.

Where to go in Brazil in December

It’s the start of summer, and the vacation season is heating up; some of the best places to visit in Brazil truly come alive in December. While crowds and rain are part of the deal, so are vibrant festivals, warm waters, and endless coastline. Here's where to go.

Bahia (Salvador, Chapada Diamantina, and the coast)

Bahia blends Afro-Brazilian culture, music, and laid-back beaches better than anywhere else. Salvador’s December calendar is packed with pre-New Year events, while coastal towns like Morro de São Paulo and Barra Grande offer barefoot bliss.

Inland, Chapada Diamantina’s waterfalls are flowing strongly and trails are lush, just start hikes early to dodge afternoon showers.

Florianópolis and the Santa Catarina coast

While Rio gets crowded, locals in the know head south. “Floripa” is a surf-and-sun playground with over 40 beaches and a buzzing summer vibe. December is early in the peak season, so you’ll catch the action before prices skyrocket.

Pantanal (for the brave)

Yes, it's wet. Very wet. But the weather in Brazil in December brings dramatic landscapes and a different side of the Pantanal: lush, flooded, and teeming with birdlife. If you’re up for a wild, muddy adventure, it’s unforgettable.

At midnight, the sky explodes in color over the ocean, while revelers dance to samba, drink caipirinhas, and celebrate life.

Horseback riding in Pantanal
