Weather in Foz do Iguaçu

Foz do Iguaçu exists for one reason — the thundering wall of Iguazu Falls, nearly 3km wide and split between Brazil and Argentina, with a spray cloud visible long before you hear the roar. The Brazilian side gives the big panoramic view from raised walkways, while boat trips run right up to the base of the Devil's Throat for a proper soaking, and the surrounding national park is thick with toucans, coatis and butterflies.

Frequently asked questions

When is the best time to visit Foz do Iguaçu?

May to September (dry season) has lower water levels but more comfortable temperatures and fewer crowds; December to March is hot, humid and the falls are at their most powerful.

Should I visit the Brazilian or Argentine side of the falls?

Both if possible — Brazil offers the best panoramic overview in a half-day visit, while Argentina's trails get you closer to individual falls and the Devil's Throat. Many visitors do both over two days.

Do I need a visa to cross into Argentina for the falls?

UK and most Western passport holders don't need a visa for short visits, but check current requirements before travelling, and bring your passport for the border crossing.

Is the Itaipu Dam worth visiting?

Yes, if you have an extra day — it's one of the world's largest hydroelectric dams and offers guided tours explaining its scale and engineering.

How do I get around Foz do Iguaçu?

Local buses run from the city centre to the national park entrance and the airport; taxis and ride-hailing apps are widely available and affordable for the Argentine border crossing.

Traveler reviews

★★★★★

Nothing prepares you for the scale of it — stood on the walkways getting misted by spray with toucans flying overhead. Did both sides over two days and it was worth every minute.

★★★★★

Visited in the wet season and the falls were at full power, almost deafening. The boat ride under the Devil's Throat soaked us completely but it was the highlight of our whole trip.

Priya K. · February 2024

★★★★☆

Dry season meant comfortable walking weather and the falls were still spectacular. The Itaipu Dam tour the next day was a surprisingly interesting contrast.
