What to expect in Alter do Chão in August
Editor's tip
August is the heart of winter in Alter do Chão. 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. 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.
