What to expect in Lençóis Maranhenses in December
Editor's tip
December finds Lençóis Maranhenses in the middle of summer. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Highs reach 32 °C (90 °F): the heat calls for early starts, sunscreen, and spending the middle of the day in the shade or in the water. It is one of the busiest times of the year: the destination fills up, rates go up and the best hotels sell out early. Book ahead or choose weekdays. It also rains very little: this is one of the driest months of the year, good for anyone who wants an outdoor itinerary.
