Iguazú River sets the record of our series at the Falls: 11,831 m³/s
Guia 3 newsroom · edited by Annie GrellmannUpdated on PortuguêsEspañol
The Iguazú River reached 11,831 m³/s at the Falls at 5 am on 12 October, the highest value in the series Guia 3 has tracked since 17 June 2026 and almost eight times the historical average. By the afternoon the flow was already easing.
The ANA gauge at the Hotel das Cataratas recorded 11,831 m³/s at 5 am on 12 October: the highest value in the series Guia 3 has tracked since 17 June 2026 and almost eight times the historical average of 1,500 m³/s. That is about 4.7 Olympic pools every second. The baseline matters: the river's record is 46,300 m³/s, in June 2014, so today's figure is a record for our series, not for the Iguazú's history.
The flow stayed above 11,800 m³/s through the night and began to fall in the morning: 10,914 m³/s at 5 pm.

If you are visiting
With the walkway closed, you see the falls from the trail viewpoints, which are soaked in spray at this flow: bring a raincoat. Check the day's status in are Iguazú Falls open today? and the hourly river reading in Iguazú Falls today.
The same rain raised the Paraná, a different river with a different gauge: see Paraná River rises 5 meters in 24 hours.
