At 2,300 miles long and with a variety of different landscapes, Argentina's vast territory makes it the eighth largest country in the world. Across such huge swathes of land, the altitude varies a lot, ranging from -330ft to more than 21,300ft. As a result, Argentina is home to a lot of different climates, largely influenced by altitude and latitude. However, as it's located in the southern hemisphere, the seasons there are the opposite of ours. The weather also varies depending on the location between latitudes 22° and 56° south. The northernmost regions of Argentina are the warmest, with a subtropical climate, while the southernmost regions are influenced by the Arctic, and are therefore in what's known as a 'subarctic' climate zone. We've put together a guide on the differences in weather across the country's main cities and regions, explaining the best time to visit Argentina.

Buenos Aires


Buenos Aires has a temperate, humid climate. Winter here is relatively mild (May to September), with the coldest month of July averaging 11°C (the average minimum temperature is 7.6°C and average maximum is 15.4°C). On the other hand, January is the warmest month in Buenos Aires, with high humidity that can feel stifling. The average temperature during that time is 24.5°C, with an average minimum of 19.6°C and average maximum of 29.9°C, but temperatures can reach up to 40°C . The humidity is often alleviated by the two winds which prevail in Buenos Aires. The pampero wind from the south-west is the most prevalent and cools the hot summer temperatures. Buenos Aires' other wind is the sudestada from the south-east. It's wetter and colder, and is usually felt in spring and autumn.

Misiones and Corrientes


In north-east Argentina, the provinces of Misiones and Corrientes have a subtropical climate, with no dry season as such in Misiones, making it the wettest region in the country. While Corrientes enjoys a relatively temperate climate, as you go deeper into the province of Misiones the humidity rises to between 75% and 90%. There is also a lot of rainfall, especially at night. Winter temperatures range from 16°C to 18°C, while summer temperatures (January and February) average 25°C, with peaks possibly reaching above 40°C. Watch out for strong winds in these regions that usually come from the northeast, southeast and east.

Sierras de Cordoba


The Sierras de Cordoba mountain range stretches through vast desert plains with some rocky areas. The climate is divided into two large zones. In the region around La Pampa the climate is temperate. In the north, however, it is subtropical, with more pronounced dry seasons (November to February), and high temperatures above 30°C and high chances of rain. This western part of the country, popular with visitors for its mountain ranges, is very pleasant with a subtropical summer climate similar to that in the Mediterranean. However, there is a real difference on either side of these ranges. The western side is arid (less than 16 inches of rain per year), while the eastern side is wetter (up to 48 inches of rain per year). For those wishing to visit cities at high altitudes, above 6500ft the average annual temperature is 14°C, and snow is quite rare.

North-West Argentina


Northern Argentina has an almost tropical (subtropical) climate. This doesn't mean that it's always hot though, as all parts of northern Argentina are used to seeing the mercury fall to 0°C. The north-west of Argentina is the driest area, and has very high temperatures in summer. Hot days there can be unbearable, with average temperatures above 35°C. Some areas, especially in the north-west, can see the mercury climb to 45°C. Winters are mild, with occasional hot days and cold nights. Average temperatures are around 20°C in the north, with cooler nights dipping down to 10°C. In winter, temperatures have been known to reach 30°C some days, while temperatures then sometimes fall to 10°C and can get down to 0°C. Rainfall in the north-west of Argentina is quite limited, with only four inches in the driest regions. Rainfall is heavier in the Tucuman and Salta provinces than in the Jujuy region, and even more so in La Quiaca, which sits at an altitude of almost 11,500ft.

Argentina's Patagonia


Argentina's Patagonia has a semi-arid to arid climate. The climate here contrasts with the rest of the country, as it's exposed to the cold by virtue of its latitude, with average annual temperatures below 12°C. The Atlantic side of Patagonia is dry and windy, with very strong winds in summer between December and February. In winter, the mercury often falls below 0°C.  Patagonia is one of the world's most southerly regions, and therefore directly influenced by the southern ocean. This is why there is a mountain climate, which sometimes makes winter journeys difficult during July and August.
