What to expect in Foz do Iguaçu in October
Editor's tip
October is spring in Foz do Iguaçu. 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 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. Rain, when it comes, is usually brief and does not spoil the day.
