Marco Três newsroom · edited by Annie Grellmann
Today, July 22, 2026, the Triple Border (Foz do Iguaçu, Brazil; Puerto Iguazú, Argentina; and Ciudad del Este, Paraguay) has a high of 22°C, low of 18°C, 100% chance of rain and dollar at R$ 5.10.
With a storm forecast, the best activities are indoors: visit the Itaipu Ecomuseum, the Astronomical Pole, Dreams Park Show, the Mosque, the Duty Free and shopping malls, according to the guide "what to do in Foz do Iguaçu when it rains" (https://www.marcotres.com.br/guia/o-que-fazer-em-foz-do-iguacu-quando-chove). Iguazu Falls remain impressive even with rain – bring a rain jacket, not an umbrella. Sunset will be at 6:08 PM, with golden hour starting at 5:08 PM, ideal for photos at the Three Borders Monument. The maximum ultraviolet index is 2.3 and the Iguazu River flow is at 2,476 m³/s, above historical average.
