What to expect in São Sebastião in April
Editor's tip
April brings fall to São Sebastião. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Temperatures are pleasant, with highs of 28 °C (82 °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. If the dates line up, it is worth fitting Maresias Stop of the Surf Circuit (Etapa de Maresias do circuito de surfe) into your itinerary: it is what livens up the destination at that time of year.
