Record Flow at Iguaçu Falls
Guia 3 newsroom · edited by Annie GrellmannPortuguêsEspañol
The flow of the Iguaçu River reached 16,997 m³/s, the highest record since June 17, 2026.

The flow of the Iguaçu River at Iguaçu Falls, in the city of Foz do Iguaçu, Brazil, is 16,997 m³/s, the highest value in the series measured by Guia 3 since June 17, 2026, which corresponds to 11.3 times the long-term historical average of about 1,500 m³/s. In practical terms, this equals 6.8 Olympic-size swimming pools of water passing each second.
Flow is the volume of water that passes a point in the river each second; the higher it is, the more intense the waterfalls, the noise, and the mist in the viewing areas. When the flow exceeds 8,000 to 9,000 m³/s, the park usually closes the main walkway for safety, according to operational history.
With the current flow well above that limit, there is a risk that sections of the walkway or the Devil's Throat may be temporarily closed. Before planning your visit, check the day's status at /cataratas-hoje to confirm which areas are accessible.
What this means for you: the visit may require schedule or route adjustments within the park; if the main walkway is closed, you can still view the falls from other viewpoints, but it is essential to confirm the real-time situation to avoid surprises.
