Argentina Weather, climate and geography

Weather and climate

Best time to visit

Argentina's climate ranges from the great heat and extensive rains of the subtropical Chaco in the north, through to the pleasant climate of the central Pampas, and the sub-Antarctic cold of the Patagonian Sea in the south. The main central area is temperate, but can be very hot and humid during summer (December to February) and chilly in winter.

The most pleasant times to visit Buenos Aires are September-November and February- March. The city is best avoided in January, when the heat is at its most intense and many of its residents flee to the coast leaving behind a comparative ghost city. Exploring the wilds of Patagonia is best done in the late spring and summer months – between November and February – whilst the northern regions are at their most hospitable in the spring, autumn and winter. If heading to Argentina for a ski trip, hit the slopes during mid-June to October.

Required clothing

Lightweight clothing is generally all that is required in the north, whereas warm clothes are certainly necessary in the south, up in the mountains and during winter months in the central area. It is sensible to carry waterproofs in all areas and bring a good sunblock.


Argentina is the second largest area of land in South America, separated from Chile to the west by the long spine of the Andes. Its landscape is extremely varied, with the top sub-tropical and sun-baked, and its sub-Antarctic bottom tip glistening with icy waters and glaciers. It has 3,100 miles (4,989km) of coastline. Its eastern border is the Atlantic Ocean, with Uruguay, Bolivia, Paraguay and Brazil to the north and northeast.

Argentina can roughly be divided into four main geographical areas: the spectacular Andes mountain range, the dry North along with the more verdant Mesopotamia, the lush plains of the Pampas and the windswept wastes of Patagonia. Mount Aconcagua soars almost 7,000m (23,000ft), and waterfalls at Iguazú stretch out in a massive semi-circle, thundering 70m (230ft) to the bed of the Paraná River.

Argentina’s lowest point is Laguna del Carbón in Santa Cruz Province, sitting 105m (344ft) below sea level. In the southwest is the Argentine Lake District with a string of beautiful glacial lakes framed by snow-covered mountains. At Argentina’s southernmost tip, and so the southernmost tip of the whole of South America, is Tierra del Fuego (Spanish for Land of Fire), a stunning archipelago split between Argentina and neighbouring Chile.
