Waterfalls remain in flood: flow of 8,204 m³/s, among the highest in our series
Guia 3 newsroom · edited by Annie GrellmannUpdated on EspañolPortuguês
The flow of the Iguaçu River at the Falls is 8,204 m³/s, among the top 5% of readings in the series that Guia 3 has been monitoring since June 2026, and the Brazilian walkway remains closed.
Today's measurement indicates flow = volume of water passing per second of 8,204 m³/s at the falls, almost 5.5 times the historic average flow of about 1,500 m³/s, a value that falls within the top 5% of readings in the series that Guia 3 has been tracking since June 2026 (the highest was 10,107 m³/s on September 12). This amount equals roughly 3.3 Olympic-size swimming pools of water descending each second, creating fuller falls, louder roar, and greater mist on the walkways.
For those planning to visit Iguaçu Falls now, the situation brings some practical effects: the greater water force increases steam production, which creates more frequent rainbow photos and a rare natural-spectacle atmosphere. On the other hand, such intense flows usually lead park managers to temporarily close sections of walkways or viewpoints for safety, and that is what is happening: since September 11, the walkway on the Brazilian side has been closed, according to information released by the responsible agencies; it is recommended to confirm the status on the official website before visiting, with the trail and viewpoints open (see the news).
The recommendation is to arrive well prepared: bring a raincoat, sturdy shoes, and be ready for potentially longer queues at access points. Before heading out, check the trail status and updated maps on the official site to confirm whether any section is closed on the day of your visit.
What this means for you: the Falls are experiencing a rare high-water moment, ideal for photos and feeling nature’s power, but be prepared for heavy rain and possible area closures. Plan your itinerary in advance, check the live situation, and enjoy the unique experience that few visitors get to live.
