Where
Best time to visit Argentina is October through April, when Patagonia's hiking trails are open, Buenos Aires has mild outdoor weather, and Mendoza celebrates the grape harvest. Argentina stretches over 3,400 km from subtropical Iguazu Falls to glacial Tierra del Fuego, so every region has its own ideal window.
Seasons are reversed from the Northern Hemisphere. Argentine summer (December-February) brings long warm days to Patagonia and the Lake District. Winter (June-August) means ski season in Bariloche and dry clear weather in the northwest. Understanding regional timing is essential for planning.
