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

The measurement made by Guia 3 indicates that the flow of the Iguaçu River at Iguazu Falls, in Foz do Iguaçu (Brazil), reached 8,322 m³/s – almost 5.5 times the historic average flow of about 1,500 m³/s – a value that sits at the top of the highest 2% of the entire historical series and represents the largest record since July 25, 2023. Flow is the volume of water that passes a point each second; when the flow is high, the falls are fuller, the noise increases, and the mist on the walkways intensifies. This amount equals roughly 3.3 Olympic swimming pools of water passing every second.

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

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

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 walkway openings before leaving home.
