What to expect in Foz do Iguaçu in May
Editor's tip
May brings fall to Foz do Iguaçu. In Brazil the seasons are the reverse of those in the Northern Hemisphere. Temperatures are pleasant, with highs of 25 °C (77 °F) and nights that still call for a light jacket. 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. If the dates line up, it is worth fitting Falls Festival (Festival das Cataratas) into your itinerary: it is what livens up the destination at that time of year.
