What to expect in Foz do Iguaçu in December
Editor's tip
December finds Foz do Iguaçu 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. Rain, when it comes, is usually brief and does not spoil the day. If the dates line up, it is worth fitting Natal Águas e Luzes (Christmas of Water and Lights) into your itinerary: it is what livens up the destination at that time of year.
