For residents of the Northern Hemisphere, Argentina offers travelers the possibility of enjoying two summers in one year, but the country's great variety and elongated geography means visiting is pleasant during any season. Patagonian destinations, such as the Moreno Glacier in Santa Cruz, are best visited in the summer months (December to February ) when the weather's milder and more services are available. Outside this time, services thin out and public transport becomes trickier. Spring and autumn are the best times to visit Buenos Aires (the summer is hot and humid). Mendoza, Córdoba and the Lake District are all spectacular in autumn, when the leaves are fiery reds and yellows, the temperatures are comfortable and the crowds are few.

Northern Argentina, including the Iguazú Falls in the subtropical Misiones province, is also more pleasant in the Southern Hemisphere's winter or spring when heat and humidity are less oppressive. Ski season runs mid-June through mid-October, and the resorts are most expensive and most crowded during July and August when every porteño (person from Buenos Aires) seems to be on the slopes. The most expensive times to travel are the Argentine vacation months of January, February and July.

Weather

Argentina's climate ranges from subtropical in the north to humid and steamy in the center, and cold in the south. The upper Andes region has erratic rainfall, flash floods (in summer), searing heat, snow at higher elevations, and the Zonda - a hot, dry wind. The lowlands receive sufficient rainfall to support swampy forests and upland savanna, but rainfall decreases towards the west; shallow summer flooding is common in the east. The winter dry season is pronounced, and the summer heat can be brutal. The flat Pampas areas are also vulnerable to flooding. Patagonia is mild year-round in the east and glacial in the south. Patagonian weather ranges widely during the year, from relatively temperate in the northeast to glacial along the Andes to fairly chilly in the far south.
