This is the most popular time to visit the beaches of Santa Catarina due to plentiful sunshine and temperatures exceeding 28°C.

Up in the mountains, you can expect summer temperatures of around 25°C which rise higher on some days. Here the rainfall is fairly even throughout the year. Local holiday times run from January to February.
