Quick answer
Autumn (March to May) and spring (September to November) are the best times: pleasant temperatures and fewer people than in the holidays. Summer is very hot and humid; winter is mild and drier.
The climate
Misiones has a humid subtropical climate with no dry season: it can rain at any time of year. Summers are hot and humid, often above 30 °C, and winters are mild, with some cold mornings, especially in the central hills and the northeast.
Season by season
- Summer (December to February): intense heat and storms. Ideal for waterfalls, river beaches and lodges with pools. High season in January.
- Autumn (March to May): mild days and a green forest. A very good time for the falls and the ruins. Easter week is high season.
- Winter (June to August): mild and drier. The July winter holidays are the busiest season in Iguazú: book ahead.
- Spring (September to November): blossoms, birds and pleasant temperatures. The National Immigrant Festival takes place in Oberá in September.
Water flow at Iguazú and Moconá
The flow of Iguazú Falls depends on rainfall in the Iguazú basin, mostly in Brazil, and can change a lot from one month to the next. Moconá Falls are best seen when the Uruguay River is low. In both cases, check current conditions before travelling.
