The climate of Brazil
Brazil is the largest country in South America and the fourth largest country in the world. Brazil is mostly known for its soccer, the beautiful women and the carnival. Brazil has a complex ecological system in which the combination of climate and nature yields spectacular scenery giving the world several unique places. The Amazon is one of the most fascinating natural areas and is also described as the earth’s lungs. This is why scientists are very worried about the deforestation of this tropical rainforest which has a square surface area of several millions of kilometers. Because the largest part of Brazil is situated below the equator its seasons are the reverse of ours. During our summer it is winter in Brazil. However, wintry weather is uncommon in Brazil. If you want to go on a winter sport holiday Brazil is not the right place.

Different climate zones
Brazil has several different climate zones which can be classified as tropic and sub-tropic. Brazil only has warm climate types because of its location. The type of climate and its corresponding characteristics are determined by the situation in relation to the Atlantic Ocean, the highlands of Brazil, the Andes west of Brazil and the aforementioned Amazon. The entire Amazon area and the northern part of the highlands of Brazil have tropical climates. South-east of the mouth of the Amazon River and the entire western Amazon region have a tropical rainforest climate, type Af According to the Köppen-Geiger climate classification. The rest of the Amazon has a tropical monsoon climate (Type Am), because this area has a distinct wet period, or monsoon. The area between the Amazon and the imaginary line between Pantanal and Rio de Janeiro has a tropical savannah climate (type Aw). The higher areas in central Brazil have a warm, partially moderate savannah climate (types Cwa and Cwb). The interior in the east mainly has a warm steppe climate (type Bsh. The coastal strip between Salvador and Rio de Janeiro has tropical monsoon and tropical rainforest climates. The southern part of Brazil has a warm sea climate with warm summers and mild winters (the regions of Paraná, Santa Catarina, Rio Grande do sul and Soa Paulo). During the winter temperatures may drop below 10 degrees Celsius here, therefore this region has no tropical climate.


Climate information of places and areas in Brazil
The climate information on this page is only brief. Specific information about weather and climate can be found on the climate pages per area or town. As for Brazil the following climate information is available:

No shortage of rain in Brazil. Especially the rainforests of the Amazon and the eastern tip of Brazil (the surroundings of Recife) get a lot of rain. The western and eastern part of the Amazon in particular may get large amounts of annual rain. The wettest areas get as much as 2,000-4,000 millimeters of rain per year. These areas get large amounts of rain evenly spread out over the year. The central Amazon is drier with 1,500-2,000 millimeters of rain per year. During the winter (July till September) there is less rainfall than during the monsoon. This is why this area gets less rain on an annual basis than other regions. The rest of Brazil gets about 1,000 millimeters of rain per year; there usually is a wet and a drier season in this region. However, there are differences between the regions. For more information on these differences please visit the individual climate pages on places and regions in Brazil. The Ceará region in the north east is a little drier than the surrounding regions. However, these are statistical figures that give exact predictions as to the location and the quantity of rain. Chances are that a region gets 600 millimeters in one year and a double amount of rain the next year.

Rainy season
Some areas such as the tropical rainforests in the west of the Amazon and areas at the mouth of the Amazon have no rainy season. These locations get large amounts of rain all year round. The southern tip of Brazil is slightly wetter during winter than during summer. A large contrast can be found in the eastern tip of Brazil; the coastal area surrounding Recife. Summers are reasonably dry here, winters are very wet. More than 200 millimeters per month in May and June is not uncommon. The central part of the Amazon does have a rainy season. The period from June till September is relatively dry with 30-100 millimeters of rain per month. The swamplands of Pantanal have their rainy season from December till May. During this period about 1,000-1,400 millimeters of rain falls causing water levels to rise by 3 meters. Large areas get flooded causing them to be very fertile. This area also is the habitat of many animal and fish species. Several of them unfortunately are almost extinct through the actions of man. The area is very popular among nature lovers and people who want to catch animals to sell them for (sometimes large) amounts of money. The central part of Brazil, which is elevated, also has a wet season during the summer. The capital of Brasilia for instance gets 3-5 rainy days per month during winter. During the summer it rains almost every day causing precipitation figures to rise to 200 millimeters per month.

Brazil is a warm country. Not only the weather is warm, so are the people and Brazil’s music. Large parts of Brazil get temperatures around tropical values of 30-33 degrees Celsius all year round. Night time temperatures usually are just above 20 degrees Celsius. The southern part of Brazil is slightly cooler during winter; a pleasant 20-28 degrees Celsius on average during the day. However, night time temperatures are colder with 5-10 degrees Celsius. In the coastal area between Rio de Janeiro and Salvador you may add 5-8 degrees. Subzero temperatures are uncommon in Brazil. Only on the highest summits subzero temperatures may occur. However, bringing skis is no use, since there are no large snowy slopes.

UV-Index figures in Brazil are high. The northern part, around or just below the equator, has the highest possible figure of 11 all year round. In December and January this may be slightly lower when skies are clouded. The southern part of Brazil has high UV-index figures during summer as well causing a white skin to get sunburnt within 15 minutes. The advice is to apply sunscreen with a high protection factor. During the hottest time of the day (11-4 pm) the best advice is to stay out of the sun or cover up properly.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The information below is an average for Rio de Janeiro.
Please visit the individual pages for climate information on other places and regions in Brazil and use them as a reference. Especially in the field of precipitation and UV-index deviations may occur. The chance of wintry weather in Brazil is nil. Chances of (very) warm weather are higher in the north and lower in the south and some parts in the west.
