The climate of Argentina
As to surface area Argentina is the second largest country in South America. From the most northern part to the most southern part Argentina covers an area of over 4,000 kilometers. From the eastern part to the western part there is a difference in altitude of 7 kilometers. At 6,959 meters the Cerro Aconcagua mountain is the highest spot in South America. Salinas Chicasin which is located in the eastern part of Argentina is the lowest point in Argentina at 38.75 meters below sea level. Because of the large differences in altitude, the variations in landscape and differences in location in relation to the equator Argentina has several climate zones. The largest part of Argentina has a relatively dry desert and steppe climate; especially the Pampas which are situated centrally in Argentina. The western part of the country is a mountainous area which is part of the southern Andes. This gigantic mountain range extends for 7,000 kilometers and runs parallel to the coast of the Pacific.
The Andes zones and Patagonia situated in the southern part of Argentina both mainly have moderate Mediterranean and sea climates. The high mountain summits have a high mountain climate. The highest regions have everlasting snow and the south has an enormous permanent ice cap: the Campo de Hielo Sur or Southern Patagonian Ice Field.
The eastern part of Argentina has a combination of several types of climates. The largest part has a warm sea climate (type Cfa according to the Köppen-Geiger climate classification). The area between Buenos Aires and Bahia Blanca has a moderate sea climate (type Cfb). The northern part of Argentina has a subtropical character with a distinct dry period during the local winter months and a wet period during the summer (December till March).

Reversed seasons
Because Argentina is located in the southern hemisphere the seasons are reversed. When it’s winter here, it is summer in Argentina and the other way round. The differences in temperature increase the further south you travel. The northern part of the country has relatively small differences between summer and winter. In the city of Salta which is located in the north western part of Argentina the maximum average temperature only differs 9 degrees Celsius. The coldest month with an average maximum temperature of 19 degrees Celsius is June. November, December and January are only 9 degrees warmer; 28 degrees Celsius. However, there is a distinct dry period (April till October) and a distinct wet summer. In the rest of the country differences in seasons are a little larger. Large differences occur especially where the hours of daily sunshine are concerned.

There is no risk of hurricanes in Argentina. Hurricanes that do occur in the Atlantic region usually move toward the tropic of Cancer. However, the country has several other wind phenomena. The Vienta Zonda (Zonda winds) is a warm wind that blows from the south. The depressions that blow in a north easterly direction supply dry winds with lots of dust. During the winter this phenomenon often causes heavy snowfall; often in the form of drift-snow which can last for hours. A Zonda wind usually starts during the afternoon (12pm-6pm) and lasts for one to twelve hours on average. A Zonda may also refer to a warm and humid wind that blows from the north over the pampas. This warm wind is also referred to as Sondo.

Precipitation figures
TextThere are large differences in precipitation figures in Argentina. The south western part and the western part of Argentina are very dry. 200-400 millimeters of rain per year on average. In the southern part of Argentina and in the Andes a large part of the precipitation falls in the form of snow. The Land of Fire/Tierra del Fuego which is located in the most southern part of Argentina gets about 400-800 millimeters of precipitation per year. The most western part of Patagonia also has a much wetter character. When you travel from central Argentina toward the north east precipitation figures rapidly increase. The subtropical north eastern part along the borders with Paraguay and Brazil are much wetter than the rest of the country. This area almost gets 2,000 millimeters of rain per year. The precipitation figures in combination with higher temperatures are responsible for an entirely different kind of landscape and vegetation here.

Not only do the amounts of precipitation differ a lot in Argentina. The spread of monthly rainfall can be very different from one region to the other as well. The capital of Buenos Aires gets a fairly equal amount of rain per month. During the winter about 60-65 millimeters of rain is recorded while the autumn (March and April) get about twice that amount. The north western part of Argentina has a fiercer spread of rain. Winters are almost entirely dry, the number of rainy days are very slim. However, the summer gets a lot of rain. January and February are the wettest months; they get about 150-200 millimeters of rain per month. The dry regions in Argentina have an even spread of rain. Depending on the region you are in this will be between 5-30 millimeters of rain per month.

More climate information
Climate tables are useful but they don’t give an overall picture of the climate and possible weather conditions during a period of time. How high the chances are of hot or cold weather or hurricanes can often not be found in these tables. This is why we offer extra climate information per month. The information below is an average for Argentina.
