What to expect in Florianópolis in September

Myllena Vieira, editor at Visite
Editor's tip

September is spring in Florianópolis. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Temperatures are pleasant, with highs of 22 °C (72 °F) and nights that still call for a light jacket. Crowds sit somewhere in the middle, with peaks on public holidays. Outside those dates, you can enjoy the place at an easy pace and spend less. It rains fairly often, so keep an indoor plan handy for gray days.
