Iguazu Falls at record flow: 8,322 m³/s, among top 2%

The measurement made by Marco Três indicates that the flow of the Iguaçu River at Iguazu Falls, in Foz do Iguaçu (Brazil), reached 8,322 m³/s, a value that sits at the top 2% of the entire historical series and represents the highest record since July 25, 2026. Flow is the volume of water that passes a point each second; when the flow is high, the waterfalls are fuller, the noise increases, and the mist on the walkways intensifies. This amount is equivalent to about 3.3 Olympic swimming pools of water passing each second.

With such a strong current, the experience at the Falls can be even more impressive, but it also requires some precautions. In very high-flow situations, parks often temporarily close the final walkways of the Devil's Throat for safety. Therefore, before planning your visit, check the real-time status of the walkways on the /cataratas-hoje site.

For those who want to take advantage of this rare moment, the best strategy is to arrive early, before the biggest concentration of visitors, and wear non-slip shoes. Bring a raincoat or poncho, as the mist can get you quite wet, and protect your electronics with waterproof covers.

What this means for you: The high flow makes the visit more spectacular, but it may limit access to some areas. Arrive early, wear water-protective clothing, and confirm the walkways are open before leaving home.
