Marco Três Border Bulletin — July 2026

Dollar

In July 2026, the dollar closed the month at an average of R$ 5.12, with a low of R$ 5.07 and a high of R$ 5.20, according to the daily series from Marco Três/AwesomeAPI.

Iguaçu River Flow at the Falls

The average flow recorded was 4,454 m³/s, with a peak of 10,071 m³/s. There were 6 days with flow above 6,500 m³/s, a level that usually leads the Argentine park to close the Devil's Throat preemptively. The typical river flow (long-term average) is about 1,500 m³/s, so the month was 197% fuller than normal.

Border Aviation (June 2026)

In the last official month, 1,076 inbound flights were recorded at the border: 727 in Foz do Iguaçu, Brazil, and 349 in Puerto Iguazú, Argentina, carrying 48,823 passengers on the Argentine side, according to data from ANAC Brazil and ANAC Argentina.

Passengers at Foz do Iguaçu Airport (June 2026)

Foz do Iguaçu Airport handled 228,021 passengers, a 36.3% increase over the same month a year earlier, according to ANAC.

Fuel

In the most recent week, regular gasoline in Foz do Iguaçu cost R$ 6.43 per liter (ANP). In Argentina, super gasoline was quoted at R$ 7.39 per liter (official Argentine data converted using the blue dollar), 15% more expensive than Brazilian fuel.

Itaipu (July 2026)

The Itaipu plant generated an average of 204.4 GWh per day. Each GWh equals the daily consumption of roughly 200,000 households, with the energy destined for the interconnected Brazilian national system and almost all of Paraguay’s consumption, not Foz do Iguaçu.

What this means for you:

• Plan your trip: the dollar is near R$ 5.20, so purchases in dollars are still pricey; compare fuel prices before crossing the border, as fueling in Argentina is 15% more costly.
• Watch the river level: with flows above 6,500 m³/s, the Devil's Throat may close; check the park schedule before you go.
• Take advantage of air connectivity: over a thousand flights arrive in the region, easing travel between the three countries.
