What to expect in Ilhabela in October
Editor's tip
October is spring in Ilhabela. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Temperatures are pleasant, with highs of 26 °C (79 °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.
