Rainfall is moderate, with showers throughout the year. The best time to visit Buenos Aires is from March to May.
Andes Mountains:
The Andes experience cold winters (June to August) with snow in the higher elevations, ideal for skiing around Bariloche. Summer temperatures (December to February) vary widely, from cool (15-20°C / 59-68°F) in the mountains to warm (25-30°C / 77-86°F) in the foothills, such as in Mendoza. If you are after the colourful foliage in the Lake District, go between March and May.

Argentina's diverse climate means that clothing needs vary by region and season.
Northern Argentina:
Lightweight clothing is ideal for the subtropical north, especially during hot and humid summers. Opt for breathable fabrics, sun hats, and sunscreen. For the rainy season (December to March), pack a light waterproof jacket and sturdy shoes.
Central Argentina (Buenos Aires and The Pampas):
Light layers are recommended for summer (December to February), with cooler evenings in Buenos Aires. During winter (June to August), a warm jacket, sweaters, and closed shoes are advisable, as temperatures can drop significantly.
Andes Mountains:
The Andes require versatile clothing, including warm layers, a waterproof jacket, and sturdy footwear for hiking or skiing. Even in summer, evenings can be cool, so thermal layers and a hat are useful.
Patagonia and Tierra del Fuego:
The southern region is known for its unpredictable weather and strong winds. Pack warm, windproof, and waterproof clothing, including thermal layers, gloves, scarves, and a good quality jacket. Sturdy, waterproof shoes are essential for hiking and exploring outdoor areas.
Regardless of the season, comfortable walking shoes are recommended for city exploring, and a swimsuit may come in handy if visiting thermal springs or coastal areas.
