Higher waterfalls: what to expect on your visit this week

Guia 3 newsroom · edited by Annie GrellmannPortuguêsEspañol

The flow of the Iguaçu River is at 7,728 m³/s, almost 5.2 times the historic average of 1,500 m³/s, and this may affect access to the final section of the Falls walkway.

Today's measurement shows 7,728 m³/s (level 346 cm) on the Iguaçu River, which corresponds to ≈ 5.2 times the historic average of 1,500 m³/s (1.5 million liters per second). This flow is classified as exceptional and well above the 6,500 m³/s threshold at which the Argentine park usually closes the Devil's Throat preemptively.

During strong floods, the park generally keeps the viewpoints and most trails open, but the final section of the walkway may be halted for safety reasons – the decision is announced daily by park operators. Therefore, before planning your visit, check the updated status at /cataratas-hoje or on the official website of Iguaçu National Park.

High-flow water takes on a brown hue due to sediment washed from the rainy basin, but this does not indicate river pollution. To grasp the water's power: 7,728 m³/s equals about 3.1 Olympic-size swimming pools dropping every second, or 773 water-truck loads per second, and in roughly 6 seconds matches the daily water consumption of the entire city of Foz (285 thousand inhabitants).

What this means for you:

  • If you want the full view of the Devil's Throat walkway, arrive early and confirm the status on the day of your visit; the section may be temporarily closed.
  • Bring a raincoat or waterproof clothing, as the spray from the falls will be more intense.
  • Enjoy the still-open viewpoints and consider the Macuco Safari boat tour, which operates even at high flow.
