Balneário Camboriú sits on the Atlantic coast of Santa Catarina in southern Brazil, and its weather follows a humid subtropical pattern (Köppen Cfa) with hot, rainy summers and mild, drier winters. The city’s 7 km of beachfront high-rises stay busy all year because daytime highs rarely drop below 21°C (70°F) even in mid-winter. This is the monthly breakdown of Balneário Camboriú weather, with numbers you can plan around. See the Balneário Camboriú travel guide for the full picture.
Balneário Camboriú Weather: Climate Overview
The annual mean temperature is 20.1°C (68°F), and the city receives about 1,569 mm of rain a year with no dry season. Summer (December to March) is the wettest stretch, with January averaging 186 mm and February 209 mm, mostly as late-afternoon thunderstorms that clear within an hour. Winter (June to August) is the driest period, with July down to 79 mm. The sea off the coast runs from about 16°C in winter to 24.4°C at the February and March peak, so swimming is warmest from December through April.

Balneário Camboriú Weather in Winter (June to August)

July is the coolest month, with an average high of 21.3°C (70°F) and a daily mean of 15.8°C (60°F); early-morning lows can dip to between 4°C and 10°C, so bring a light jacket for evenings. Rainfall drops to 79 to 96 mm a month, making winter the sunniest and driest stretch of the year, though the sea cools to around 16°C and most people skip swimming. This is the cheapest season for hotels, and you can find more on that in our Balneário Camboriú neighborhoods and where to stay in Balneário Camboriú guides.
Balneário Camboriú Weather: Sea Temperature and Sunshine
Sea temperature peaks at 24.4°C in February and March, holds around 21°C through autumn and spring, and bottoms out near 16°C in July and August. Sunshine hours follow the reverse of rainfall: winter days are the clearest, while summer afternoons bring the most cloud cover. If you are planning around the summer storm pattern, pair this with our events in Balneário Camboriú calendar, since the biggest beach parties and the Réveillon fireworks fall in the wettest months.
