What to expect in Lençóis Maranhenses in May
Editor's tip
May brings fall to Lençóis Maranhenses. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Highs reach 31 °C (88 °F): the heat calls for early starts, sunscreen, and spending the middle of the day in the shade or in the water. 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.
