Heavy rains raise water volume in October 2026
On October 14, 2026, the flow of Iguazu Falls surpassed 15.5 million liters per second. The rise followed 15 days of October with over 330 millimeters of rain in Foz do Iguaçu, 50% above the monthly average.
In recent days, Iguazu Falls recorded a water volume above 15 million liters per second, reaching 15.5 million on Wednesday (Oct 14). The peak was the result of heavy rains that, over 15 days in October, accumulated more than 330 mm in Foz do Iguaçu, exceeding the region’s monthly average by 50%.
The El Niño climate phenomenon has intensified precipitation since late winter. The Iguaçu River originates near Curitiba, runs about 1,300 km, and empties into the Paraná River. On the Paraguayan side, in Ciudad del Este, floods forced the evacuation of entire neighborhoods.
The Itaipu Binational Power Plant activated additional spillways to handle the large water volume. Authorities say the dam continues operating within normal parameters. Iguazu National Park remains open, but walkways are closed as a precaution while climate conditions stabilize.
