Good to Know
- Florianopolis has subtropical weather year-round with no true dry season. Rain falls throughout the year but is more frequent December–March.
- January and February are hottest (28–29°C (84°F)) and wettest; July is coldest (around 20°C (68°F)). Neither extreme is severe.
- April–May and October–November offer the best balance: warm days (~24°C (75°F)), less rain, manageable crowds, and lower prices than summer.
- June–August is ideal for surfers and travelers avoiding crowds, though water temperatures drop to 19°C (66°F) and humidity remains high.
- Summer (Dec–Feb) brings Carnival, peak tourism, and the highest accommodation costs; expect occasional afternoon thunderstorms that usually pass quickly.
- Sea temperatures are warm enough for swimming year-round (19–26°C (66–79°F)), but peak swimming season is Nov–Feb.
