Late winter conditions persist in the south with chilly weather; cities like Buenos Aires are cool and less crowded with tourists. Good time for cultural festivals in urban centers, but not ideal for southern outdoor sightseeing.

Average temperature across Argentina in August.
Salta, Jujuy, Quebrada de Humahuaca, Cafayate
August is a month of gradual warming; the notorious winter cold eases but nights remain cool and mornings brisk. Dust and strong sun return during midday, so wear a hat and sunglasses when visiting the ruins at Quilmes or the vineyards near Cafayate. The chance of Zonda-like downslope gusts is low here - that phenomenon belongs further south - but mountain weather still changes quickly.
Iguazú, Misiones, Corrientes, Entre Ríos
August is cool and pleasantly dry, with more stable weather for road trips between Iguazú, Posadas and the Esteros del Iberá wetlands. Migrant birds are still present and the marshes of Corrientes are easier to explore by vehicle as the ground firms up. Expect fewer biting insects, clearer skies and comfortable daytime temperatures that make strolling town centres enjoyable.
Mendoza, San Juan, Uco Valley, Aconcagua approach
August begins the thaw: valley days warm into the teens and twenties while snow lingers on peaks, offering dramatic contrasts and clear skiing conditions over the border in Chile. The Zonda wind can still occur in late winter/early spring, producing sudden hot spells and gusts that affect dust-sensitive people and vineyards. It’s a good month for quieter wine tours and for watching the high mountains reopen for spring mountaineering.
Buenos Aires city, La Plata, Mar del Plata, Rosario, Tigre
August starts to warm slightly but mornings remain cool and the wind still shapes the feel of the Pampas; the first spring bulbs can be seen in city parks. Agricultural work ramps up in the countryside and rural festivals begin to reappear, making this a good time for estancia visits. Pack layers for variable days and evenings and reserve coastal weekender stays in advance as Argentines begin to travel.
Bariloche, San Martín de los Andes, Neuquén, El Bolsón
August continues the ski season with cold days and significant snowfall at higher altitudes, while valley floors are cold but slowly lengthening daylight. Winds can be fierce across exposed ridgelines and lakes, so outdoor plans should account for sudden drops in temperature. It’s a good time for winter sport enthusiasts; non-ski visitors should check access and road conditions carefully.
El Calafate, El Chaltén, Ushuaia, Puerto Madryn, Península Valdés
August starts a slow transition toward spring: days lengthen and some lower-elevation snow retreats, though powerful westerlies still dominate weather patterns. Whale-watching season at Península Valdés approaches its start, and early-season sea-bird nesting can be observed. Bring layered clothing for fluctuating temperatures; boat operators begin to gear up for the coming surge of visitors.
