The coastline of Brazil measures 7,491 km,[1] making it the 16th longest national coastline in the world. The coastline touches exclusively the Atlantic Ocean.
A considerable number of geographical features can be found all through the coastal areas, like islands, reefs and bays. Brazil's 2,095 beaches are world-famous and attract tourism[2] [3] [4] .
Although the prepositional phrase "from Oiapoque to Chuí",[4] which refers to the country's southernmost and northernmost points, is popular in Brazil, the country's true northernmost and southernmost points are located at Monte Caburaí in Roraima and in Santa Vitória do Palmar, respectively.
Out of Brazil's 26 states, 9 are landlocked, including the Federal District. Of Brazil's 17 states, most have capitals near the coast, with the exceptions of Curitiba (Paraná), São Paulo (São Paulo), Porto Alegre (Rio Grande do Sul), Teresina (Piauí), Belém (Pará) and Macapá (Amapá). Even so, the latter four of the capitals listed are near major waterways.
The southernmost point of Brazil is located near the Brazil-Uruguay border, within the municipality of Santa Vitória do Palmar. A few kilometers to the north lies the Praia do Cassino, which is 212 to 254 km long[5] [2] . Variation among sources in measurement of the beach's length has raised debate regarding whether the Praia do Cassino is the longest beach in the world, but it is indisputably the longest in Brazil.[5] The only island on Rio Grande do Sul's coastline is the small, rocky Ilha dos Lobos in Torres.[6]
The capital of Santa Catarina is Florianópolis, located at one of the country's largest coastal islands, the Ilha de Santa Catarina, which spans an area of 424.4 km².[7] The Serra do Mar mountain range starts in Santa Catarina, and follows the coastline north, ending in Espírito Santo.
Paraná's coastline is small compared to other states, but it is very diverse geographically, containing a considerable number of islands and bays.
São Paulo, contains famous coastal cities such as Guarujá, São Sebastião and Ilhabela. The northern portion of the coastline of São Paulo, as well as part of that of Rio de Janeiro, are the only southern-facing stretches of Brazil's coast, not including small islands and bays.
The state of Rio de Janeiro is often recognized for popular beaches in the capital city, like Ipanema and Copacabana. The state also contains the Campos Basin, the largest petroleum-rich area in Brazil. Covering an area of 100,000 km² and extending to Espírito Santo, the basin produces 1.49 million barrels of oil every day.[8] . 1,200 km east of Vitória, in Espírito Santo, lie the islands of Trindade and Martim Vaz.
Bahia has the longest coastline of the Brazilian states, and also the greatest number of coastal municipalities. Porto Seguro is regarded as the first place in which the explorer Pedro Álvares Cabral set foot.
From Sergipe to Ceará, the landscape changes little. The coastal landscape contains few mountains, and most of the islands are separated from the continent by narrow channels.
Piauí has a coastline of only some 60 km, the smallest of any Brazilian state. It is comprised of the cities Cajueiro da Praia, Ilha Grande Luís Correia and Parnaíba.
Maranhão is noted for its unique geographical features such as Lençóis Maranhenses. The area between Maranhão and Pará is dominated by the "Reentrâncias Maranhenses", a landform similar to a fjord but shorter, narrower and lower. Because of this particular geography, there are almost no beaches at this section of the Brazilian coastline.
Half the coastline of Pará is composed of the mouth of the Amazon River, which flows towards the sea around the Marajó island, the largest island surrounded by fresh water in the world.[9] The outflow of the Amazon River is so strong that the ocean waters in the north and northeast faces of the island have almost no salt.
Amapá's coastline is almost 600 km long, but there are only three beaches: Fazendinha, Boca do Inferno and Goiabal. The coastline of Brazil ends at Cape Orange, in the city of Oiapoque.
