Guia 3 newsroom · edited by Annie GrellmannPortuguêsEspañol
Today, 11/03, the Triple Frontier (Foz do Iguaçu, Brazil; Puerto Iguazú, Argentina; Ciudad del Este, Paraguay) has a high of 25 °C, a 78% chance of rain, and the dollar at R$ 5.44.

The day will be humid with a likely storm; take advantage of covered attractions such as the Itaipu Ecomuseum, the Astronomical Pole, and the Dreams Park Show. The Iguaçu Falls remain impressive even with rain – bring a light raincoat, not an umbrella. Sunset occurs at 18:55, with the golden hour at 17:55, ideal for photos at the Three Borders Landmark. The UV index reaches 8.6; use sunscreen. The flow of the Iguaçu River is 4,158 m³/s; be careful near the falls. Source: Guia 3 Data (Open-Meteo, AwesomeAPI, ANA, Nager).
