Argentina climate overview

Argentina is the second largest country in South America and occupies most of the southern portion of the continent with a long Atlantic coastline. About 85% of the population are of European origin, making it the most 'European' of all South American countries and over one third of Argentineans live in or around the cosmopolitan capital, Buenos Aires.

The geography of Argentina is dominated by the Andes Mountains that stretch along the entire length of its western border with Chile. From the base of the mountains a gently undulating plain gradually extends eastward down to the Atlantic Ocean.

The most fertile region is the central eastern area known as the Pampas, a vast expanse of flat treeless grassland now transformed to growing wheat and other cereals, and raising cattle. Rainfall is higher in the summer than the winter on the Pampas, however the percentage of daylight hours with bright sunshine is also higher in summer. Rainfall in all months decreases with distance from the sea.

The north of the country is tropical with a winter dry season. At low elevations summers can be hot and humid but winter temperatures are generally comfortable, though frosts do occur throughout the region. Some rain falls in the east during the winter months and the vegetation reflects this, with areas of rainforest in the extreme north east of the country.

Western Argentina is arid because the prevailing winds in this region blow from the west off the Pacific Ocean and deposit their moisture as rainfall in Chile on the western side of the mountains. The eastern slopes receive very little rain, and desert conditions extend in a swathe down the west of the country and, between the Colorado and the Deseado Rivers, as far as the Atlantic Ocean. What little rainfall there is falls generally in the summer months.

South of here lies Patagonia, an enormous desolate region of inhospitable mountains and plateaux with snow-capped volcanoes and glaciers. Rain or snow falls mostly during the freezing cloudy winters, while the cool summer months tend to be windy but mostly dry. Poor soils and the lack of rainfall make this region unsuitable for cultivation and consequently it is sparsely populated.
