What to expect in São Sebastião in August
Editor's tip
August is the heart of winter in São Sebastião. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Temperatures are pleasant, with highs of 25 °C (77 °F) and nights that still call for a light jacket. Crowds are light, which tends to work in favor of travelers: shorter lines, more peace and quiet, and cheaper lodging. Rain, when it comes, is usually brief and does not spoil the day.
