When to go when – our guide to Iguazú Falls travel
December - February
These are the peak summer months, with a spike in heat (up to 40°C), rain and humidity. Thanks to the rainfall, the falls are at their fullest and most dramatic, soaking onlookers in a refreshing spray. Visitor numbers are high as this is Latin American holiday time, and some trails may become inaccessible due to the wet climate.

March - August
There are not so many visitors during these months, with the exception of Easter week, which can be busy. From April – June you’ll spot colourful butterflies in the jungle foliage and rainbows among the misty spray. Temperatures cool over this period, and can be crisp (below 10°C) in the mornings from June – August, making this an ideal time for energetic outdoor activities such as hiking and cycle rides. Though the climate is cooler, most days are clear and sunny.
