Climate and weather in Puerto Iguazú

Understanding the humid subtropical climate of Puerto Iguazú

Puerto Iguazú enjoys a humid subtropical climate influenced by its proximity to the Iguazú and Paraná rivers. Variations in altitude between the city and the falls create microclimates with constant humidity and regular rainfall, which are particularly important for your visit to the natural sites.

Puerto Iguazú urban area: Slightly drier climate, moderate urban heat island effect
Iguazú National Park: High humidity, frequent fog near the falls, cooler temperatures
Triple Frontier: Confluence of rivers creating a more humid microclimate
