Brazil’s weather can be unpredictable if you don’t know its seasons well. Since it’s such a large country, spread across different latitudes, the climate changes a lot depending on where you are. Expect everything from tropical rainforests to temperate regions and the humidity-packed Amazon jungles. Let me walk you through the weather so you can plan your trip based on what you want to see and do.
Brazil’s Climate Overview
Brazil has a very diverse climate due to its size. The northern part of Brazil is much more tropical. As you move south, the weather becomes milder and resembles a more temperate climate. Brazil’s summer runs from December to February, while its winter is from June to August.
Rainy seasons vary by region. The Amazon area gets rain most of the year, while the southeast has heavy rainfall between November and March. The country is huge, so don’t be surprised if one part has a sunny day while another part has a storm.
Here’s a handy breakdown of how the weather changes month by month.
Brazil’s Weather in January
January is deep into Brazil’s summer. Expect hot, humid, and sunny days, especially in cities like Rio de Janeiro and São Paulo. Temperatures often hit 30°C (86°F) or higher. This is also a rainy month in many places, especially in the southeast. Beach towns will have crowds, as tourists from both Brazil and around the world flock to the coast.
If you’re planning activities, make sure to incorporate some beach days and city tours, but pack for the heat. Bring light clothes, a hat, and sunscreen. Don’t forget an umbrella in case of the sudden rain. The Amazon will be quite wet this time of year, so keep that in mind if you’re thinking about heading there.
Brazil’s Weather in February

Brazil’s summer is still going strong in February. It’s Carnival season, so expect lots of festivities and excited crowds, especially in Rio. The weather is still extremely hot and humid, with temperature averages around 30°C (86°F). The southeast regions continue seeing showers, so be prepared for both sun and rain.
If you’re coming for Carnival, pack comfortable clothing since you’ll be outside partying or sightseeing for extended periods. Again, a mix of light clothes, sunscreen, and a rain jacket is a good idea to cover all bases.
Brazil’s Weather in March
March marks the end of Brazil’s summer. You’ll still experience warm weather, with temperatures around 27°C-29°C (80°F). While rain is still common, the number of rainy days starts to decrease as the month progresses.
Milder days make it a good time for hiking in national parks or enjoying the coastal areas. Bring light clothing, but pack a light sweater for the evenings in the more southern regions.
Brazil’s Weather in April
By April, you’ll start feeling the transition toward fall. The temperatures drop slightly, with averages around 25°C-27°C (77°F), and the rain starts to quiet down in places like Rio and São Paulo.
April is perfect for travelers looking to avoid heavy crowds. The beaches aren’t as packed, but the weather is still pleasant for swimming and outdoor activities. If you’re going toward the south, bring a light jacket for cooler evenings.
Brazil’s Weather in May
May is the official start of fall as cooler weather begins. Expect temperatures to range between 22°C-25°C (72°F), especially if you’re in the southern parts of Brazil. The northeast stays relatively warm and sunny.

This is a good time to explore cities, national parks, and historic towns since the weather is comfortable for walking around. Beach days are still good, but water might feel colder in the south. Bring layers, especially if you’re traveling far south or into rural, higher-elevation areas.
Brazil’s Weather in June
Winter arrives in June, but don’t expect freezing temperatures unless you’re in the southernmost parts of Brazil. The south can dip into chilly 15°C (59°F) days or even lower during the evenings. In the north and along the coastline, it’s much warmer, with temperatures ranging from 20°C-26°C (68°F-79°F). Rain becomes less frequent.
June is a popular month for festivals like Festa Junina. Pack warmer clothes, especially if visiting southern cities like Porto Alegre. Layers are key so you can adjust as the temperature changes throughout the day.
Brazil’s Weather in July
July is Brazil’s coldest month, but the cold is mostly noticeable in the south. Inland areas, especially near São Paulo and Campos do Jordão, can drop close to freezing, while places like Rio de Janeiro stay cool but not overly cold. You can expect temperatures between 13°C-23°C (55°F-73°F).

If you’re heading to tropical areas like the Amazon or the Pantanal, expect warm but pleasant weather. It’s an excellent time for nature activities. Pack for cooler weather in the south and milder conditions in the north.
Brazil’s Weather in August
August still falls within Brazil’s winter season. Southern Brazil continues to see cool days, but places like Rio and the northeast have warm, dry weather. In fact, many people consider August the best month to travel to the northeast or explore the Amazon.
Pantanal wildlife viewing reaches its peak, so if you’re into nature and safaris, this is a great time to go. Pack a mix of light clothing for warm days but include some layers if you’re visiting southern cities.

Brazil’s Weather in September
September marks the start of spring. Northern parts of Brazil remain warm, while the south starts seeing an increase in temperature. Rio, for example, begins to heat back up to around 24°C-26°C (75°F-79°F). Rain chances rise again, especially in the north, making the weather a bit unpredictable.
September is ideal for seeing the Amazon at its fullest, especially if you like the combination of rain and sun in the rainforest. For other areas, pack summer clothes but always carry a light jacket. If you’re doing outdoor activities, be ready for a mix of weather conditions.
Brazil’s Weather in October
October brings spring in full swing. The south starts getting closer to summer temperatures, reaching around 26°C-30°C (79°F-86°F). Rain patterns increase, especially in the Amazon and tropical northern regions.
If you’re visiting rainier areas, like the north or the Amazon, make sure you pack breathable rainwear, and if you’re staying on the coastline, sun protection is key. October is also a good time for beach visits before the summer crowds arrive.
Brazil’s Weather in November
November is the bridge between spring and summer. Cities like Rio, São Paulo, and Salvador will reach around 30°C (86°F), and the humidity starts to rise. Expect more rain in most areas, especially in the southeast.
This is a great time to hit the beaches before the crowds roll in for the holiday season. Pack cool, airy clothes, a hat, and sunscreen—but also a poncho for random rainstorms. If you’re going to the Amazon, get ready for rain and mosquitoes.
Brazil’s Weather in December
December is the beginning of Brazil’s summer. Temperatures are high, especially in coastal cities, with averages around 30°C-35°C (86°F-95°F). The holiday rush makes popular spots like Rio, Florianópolis, and Búzios very crowded.
If you’re coming for the festivities or New Year’s, pack summer clothes and a lot of sunscreen. For northern cities, you’ll also want to pack for the rain, as December hits the start of Brazil’s wet season in tropical areas.
Best Time to Visit Brazil
Overall, Brazil can be visited year-round, depending on your interests. If you’re looking for the Amazon, the dry season between June and November is the best time for wildlife watching. For beach lovers, November to March is ideal for the coastline, but you’ll have to deal with occasional rain.
If you want to avoid crowds, go in May or September when the weather is milder, and there are fewer tourists. If you’re into festivals like Carnival or New Year’s Eve, plan for February or December, but expect high prices and packed destinations.
General Packing Tips for Brazilian Weather
Here’s a quick guide to pack for Brazil:
- For summer (December-February): light clothes, sunscreen, a hat, and good shoes for walking. An umbrella or rain jacket is handy too.
- For fall or spring (March-May, September-November): layers; pack a mix of warm and cool clothes since the weather can swing.
- For winter (June-August): bring some extra layers if you’re visiting the south. Up in the north it’s pretty warm, so you can still wear lighter clothes.
Always pack sunscreen and bug spray if you’re heading into nature, especially the jungle, and comfortable walking shoes.
