What Are the Warmest Cities in Brazil?

What Are the Warmest Cities in Brazil?

The three warmest cities in Brazil are Boa Vista, Mossoró, and Marabá.

Known for high daytime temperatures and high average temperatures overall year round, there are few large countries as developed as Brazil that are also so hot. The tropical climate prevalent in most of the country makes it humid and hot, particularly in the rainy season.

Brazil lies in two hemispheres: the Northern and the Southern Hemisphere. Most of the country is in the Southern Hemisphere where the seasons are inverted (June is the beginning of winter).

In this article I’ll share with you my list of the warmest Brazilian cities, researched from a list of the most populous cities in Brazil. I’ll cover the top 10 with the highest annual temperature in more detail and then present the entire ranking in a table with 100 major cities in the country.

Top 10 Warmest Cities in Brazil

Top 10 Warmest Cities in Brazil

Here are the top 10 warmest places in Brazil. The places are ranked by their average annual temperature. Each city also includes temperatures in July (usually the coldest month) and January (usually the warmest month). The tropical cities in Brazil that are located in the northern part of the country or close to the equator have higher temperatures in July than in January.

1. Boa Vista – 28.75 °C

The hot and humid climate of Boa Vista, the capital of the state of Roraima in northern Brazil, makes it the warmest city in Brazil. The city maintains very hot temperatures year round, not even dropping below 31 °C during the coolest month (June). Meanwhile, the hottest month (October) reaches 34 °C. Because of the tropical climate, the city has relatively little sunshine, at 1,896 hours a year.

Average high temperature in July: 31.4 °C

Average high temperature in January: 33.3 °C

2. Mossoró – 28.05 °C

Mossoró is the second most populous city in the state of Rio Grande do Norte. It’s located halfway between Fortaleza and Natal. But unlike these two coastal cities, it’s located inland. Mossoró has consistently higher average daytime temperatures than Boa Vista but has cooler nights (which is why it’s ranked second). The city features a semi-arid climate with relatively low precipitation for Brazilian standards. This makes it the sunniest city in Brazil out of all 100 major cities. Mossoró enjoys 2,828 sunshine hours a year.

Average high temperature in July: 32.5 °C

Average high temperature in January: 34.1 °C

3. Marabá – 28 °C

Marabá is a city in the state of Pará, located inland as the previous two cities. During its dry season, between June and October, the city experiences the highest temperatures, reaching on average up to 34.7 °C in the hottest month (August).

Average high temperature in July: 34.2 °C

Average high temperature in January: 31.4 °C

4. Teresina – 27.8 °C

Teresina is the capital of the state of Piauí. The city records extremely hot temperatures in its dry season. In the hottest month, October, it experiences average temperature during the day of 36.4 °C. Humidity in the dry season is much lower than in the rainiest months, though, so the temperatures may be more bearable than the 32 °C in the wet season combined with high humidity.

Average high temperature in July: 33.3 °C

Average high temperature in January: 32.2 °C

5. Manaus – 27.65 °C

Manaus is the capital of the state of Amazonas. Located in the center of the world’s largest rainforest close to the equator, Manaus has extremely wet and humid weather year round. While temperatures are lower than in the previous cities, the relative humidity in Manaus drops at most to 77% in the least humid month. Meanwhile, in the most humid months (definitely the worst time to visit), humidity reaches 87%.

Average high temperature in July: 32.1 °C

Average high temperature in January: 30.9 °C

6. Macapá – 27.65 °C

Macapá is the capital of Amapá state. It’s located on the Amazon River near its mouth on the Atlantic Ocean northeast of the city. The equator runs through the middle of the city, giving the city a long wet season with very high humidity year round. Average relative humidity in the most humid month, April, is even higher than in Manaus as it reaches 88.1%. The dry season in Macapá runs only for four months, between August and November.

Average high temperature in July: 31.6 °C

Average high temperature in January: 30.2 °C

7. Palmas – 27.55 °C

Average high temperature in July: 34.5 °C

Average high temperature in January: 31.8 °C

Fortaleza is the capital of the state of Ceará and the fifth largest city in Brazil. It’s the only city in this ranking of ten warmest Brazilian cities that’s located directly on the Atlantic Ocean. While the city has a hot, tropical climate with high humidity, the winds blowing from the ocean moderate it and make the weather conditions more comfortable. Temperatures in Fortaleza are consistent year round, differing very little between the hottest and the coldest month. The dry season runs from July to December while January to June is the wet season.

Average high temperature in July: 30.6 °C

Average high temperature in January: 31.2 °C

9. Imperatriz – 27.35 °C
