General and Geography

The Iguazú Falls are located directly on the border between Argentina and Brazil, not far from the border triangle with Paraguay.

Due to the different national languages Spanish and Portuguese there are also different spellings for the world-famous waterfalls, since the Brazilians write the river Iguaçu, whereas the Argentine line Iguazú. Both variants, of course, describe the same natural spectacle.

With a total width of 2.4 miles, Iguazú is home to over 250 large and small waterfalls, making it undoubtedly one of the most breathtaking waterfalls in the world.

As the largest area is on the Argentine side, the Brazilian side of the national park offers a better overview and fantastic panoramic views. The border crossing is somewhat unbureaucratic, which is why we strongly recommend visiting both sides for a visit to the Iguazú waterfalls.

The city of Foz do Iguacu itself is not worth seeing, but it has a small airport with good connections to Sao Paulo and Rio de Janeiro.

Climate at the Iguazú Waterfalls

License Information available under 'Proof of Image Sources' The region around Iguaçu and Iguazú has a humid, subtropical climate, which runs opposite to the European seasons. Midsummer is therefore between the end of November and the end of February, but winter from the beginning of June to the end of August.

The climate in summer is hot and sometimes quite humid, especially around Christmas until the end of January the highest average temperatures are often recorded. The humidity is also extremely high during this time. Precipitation can occur in the region at any time of year.

Nevertheless, the Brazilian winter, especially the month of July, is not only significantly cooler but also noticeably drier. Especially at night it can now cool down to up to 10 °C, during the day average values of around 24 °C are usually reached.

When is the best time to visit the Iguazú Falls?


The waterfalls in Iguazú are worth a visit all year round, with the main season for South Americans being during the summer holidays (i.e. in the German winter towards December and January). The falls reach their highest water level between December and March, not least because of the higher rainfall.

The best time to visit Iguazú also depends to a certain extent on your own expectations: the Brazilian winter is too fresh for some visitors, but the sky is often clear and there are fantastic rainbows. In addition, the paths are now easier to pass with slightly lower water levels and additional outdoor activities are now possible.

Our tip for the best time to travel to Iguazú Falls is a combination of pleasant weather with moderate temperatures and a good chance of blue skies for even more beautiful impressions and photos. According to this, we particularly recommend March to the beginning of May and August to September to visitors.

Due to the good travel conditions also outside these core times, we can recommend the entire period from February (i.e. after the end of the absolute high season) to the end of September to our readers with a clear conscience.

Hotels and recommendations


Even if there are accommodations for every travel budget in the surrounding villages, a stay directly in the National Park makes the visitor to the waterfalls even more extraordinary. In the Iguazú National Park (Argentina), only the upscale Sheraton Iguazú Resort & Spa has this exclusive location.

On the Brazilian side, the luxurious Belmond Hotel das Cataratas (our hotel tip!) is one of the best hotels in South America directly on the falls, surrounded by dense rainforest. For the visit of the waterfalls two full days should be planned, one of them on the Argentine side.

The two national parks have a colourful fauna, with the cheeky coatis at the Iguazú waterfalls being omnipresent. The highlight of the falls is the mighty Garganta do Diabo, where the wooden bridges lead into the heart of the waterfalls.

    Ursula, 52 years old was there in November

    We didn’t have any sun. Nevertheless, there were unbelievable moments with lots of water and a permanent roar of the waterfalls. I don’t want to miss this atmosphere with a lot of steam and spray in connection with defuse lighting conditions! If the weather is fine, anyone can!

    Weather Rating: 3 stars – Mixed
