What to expect in Alter do Chão in March

Myllena Vieira, editor at Visite
Editor's tip

March brings fall to Alter do Chão. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Highs reach 30 °C (86 °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. It rains fairly often, so keep an indoor plan handy for gray days.
