Flow of 11,880 m³/s at the Falls: walkway may be closed
Guia 3 newsroom · edited by Annie GrellmannPortuguêsEspañol
The flow of the Iguaçu River at the Falls is 11,880 m³/s, among the top 1% of the Guia 3 series since June 17, 2026.
Today's measurement shows a flow of 11,880 m³/s, which corresponds to 7.9 times the historic average of 1,500 m³/s and places the river among the top 1% of the Guia 3 series since June 17, 2026. This amount equals 4.8 Olympic-size swimming pools of water passing each second – flow is the volume of water that passes a point in the river every second.
When the flow exceeds about 8,000-9,000 m³/s, the Brazilian park usually closes the main walkway of the Falls for safety reasons. At 11,880 m³/s, the current is well above that limit, which could mean restricted access to sections of the walkway, the Devil's Throat, and some viewpoints.
What to do: before planning your visit, check the updated status of the walkways and observation points on the official website of Iguaçu National Park or at /cataratas-hoje. This check ensures you don’t arrive at the park and find unexpected closures.
Practical tip: if the walkway is closed, consider exploring other park attractions, such as lower-level trails, the Bananeiras Trail viewpoint, or the Macuco Safari boat tour, which usually operates even at high flow.
What this means for you: the high flow indicates a larger volume of water and mist, but also a risk of the main walkway being closed; confirm the status on the day of your visit and adjust your itinerary as needed.
