Ten-year averages for this calendar month. A rainy day is one with at least 1 mm of rain, as a weather station counts it. The model these figures come from drizzles more than a rain gauge, the more so the warmer the month, so its days count from 2 mm, rising to 5 mm in the hottest.

Weather read at Puerto Iguazú, 18 km from the airport (IGR): ten years of ERA5 and ERA5-Land reanalysis, through Open-Meteo's open data.

How busy it gets

May: quiet. Busiest in January and February; quietest from April to June.

Public holidays in May

Holidays crowd a place out and push fares up around them; they count toward the crowd score above.
