Falls Flow Below Average: What It Means for Your Visit
Marco Três newsroom · edited by Annie Grellmann
The flow at the Falls is 1,173 m³/s, about 0.78 times the historic average of 1,500 m³/s, i.e., below normal.
The measurement indicates 1,173 m³/s (cubic meters per second – volume of water that passes in one second). This corresponds to 0.78 times the historic average flow of 1,500 m³/s of the Iguaçu River at the Falls, placing the flow in the typical range and well below flood levels.
In practical terms, the water that tumbles over the drops equals an Olympic-size swimming pool every 2.1 seconds, or 117 water-truck loads per second. In about 37 seconds that volume would be enough to meet the daily water consumption of the entire population of Foz do Iguaçu (approx. 285 thousand residents).
Because the flow is reduced, the viewpoints and most walkways remain open, and the risk of closing the final walkway – which only happens during very intense floods (e.g., 24,000 m³/s in Oct 2023) – is low. Still, it is recommended to check the park status on the day of your visit at /cataratas-hoje before heading out.
What this means for you:
- Expect a calmer flow over the drops, ideal for photos with little mist.
- You can walk the trails and viewpoints without restrictions.
- Bring a light raincoat or umbrella, as the water may still be cold and humidity high, but there is no risk of interruptions to the attractions.
