Florianópolis

Florianópolis is a subtropical island off Brazil’s southern coast that packs 42 beaches into a 54km stretch of dramatic coastline. The state capital of Santa Catarina, it draws surfers chasing winter swells at Joaquina, families wading into the calm bay waters at Jurerê, and travelers exploring Azorean fishing villages that date from the 1700s. The island’s climate gives you warm summers from 28 to 30°C and mild winters around 20°C, with year-round humidity keeping the Atlantic Forest lush. Two bridges connect the island to mainland Brazil, but once you are here, the dual personality of bay-side calm and ocean-side energy defines every day.

Welcome to Florianópolis

The island splits naturally into distinct regions. The east coast faces the open Atlantic with powerful surf, sand dunes at Joaquina, and the lively social hub of Lagoa da Conceição. The north coast faces the protected bay with calm, shallow water and upscale resorts at Jurerê Internacional. The south preserves fishing villages like Pântano do Sul and Ribeirão da Ilha where oyster farms line the bays and seafood restaurants serve the morning catch. The west coast, facing the mainland, holds the historic center, colonial Azorean architecture in Santo Antônio de Lisboa, and the best sunset views over the bay. The island’s geography means you can surf overhead waves in the morning and paddleboard on flat water in the afternoon, all within a 20-minute drive.

Where Is Florianópolis?

Florianópolis is the capital of Santa Catarina state in southern Brazil, located on Santa Catarina Island (Ilha de Santa Catarina) and a small mainland portion. The island sits at 27°35’S latitude, roughly parallel with Brisbane, Australia or Durban, South Africa. It is about 700km south of São Paulo (1h15m flight), 1,150km south of Rio de Janeiro, and 1,700km north of Buenos Aires. The island is 54km long north-to-south and 18km at its widest point, with a total area of 424 square km. Two road bridges connect it to the mainland: the historic Hercílio Luz Bridge (opened 1926, now pedestrian and bicycle only) and the Colombo Salles Bridge for vehicle traffic. The Serra do Mar mountain range rises behind the mainland, and the Atlantic Ocean stretches uninterrupted to the east, which is why the surf is so consistent , there is nothing but open ocean between Florianópolis and Africa.
