Due to its geographical location, the climate in Argentina varies from sub tropical in the north to sub polar in the south. The sub tropical areas include Misiones, Corrientes and Entre Rios and have high levels of rainfall all year round with no dry season while the tropical part of the country does have a dry season in the first six months of the year and covers the areas west of Chaco and Formosa, among others.

The capital city of Buenos Aires has a more moderate climate with no significant dip in temperatures for a winter season. In 2007 the city experienced only its second snowfall; the last recorded snow there had been in 1918. To the south of the city there is the arid region and further south again there is the sub polar area. The Buenos Aires area has an average monthly rainfall of between 55mm in the summer months and 95mm in the winter months.

Summer in the north of the country sees average temperatures of between 33 and 37°C and the south fluctuates between 10 and 21°C, reflecting the cooler climate and higher rainfall. The warmer seasons are between October and April. The summer also sees an average nine hours per day of sunshine though the far south of the country can be up to 19 hours.

Winter averages can be as high as 22°C in the north and as low as 5°C, while the south of the country is consistently below freezing. Winter is characterised by long nights, with an average of just four hours per day of sunshine. The mountainous regions of the country experience heavy snowfall during the cooler months between May and September.

Argentina experiences both hot and cold winds that are both powerful and destructive. The Pampero hits the south of the country after a cold spell, while the Viento Norte is warmer and comes from the north during the winter, leading to milder temperatures. The Zonda is a particularly hot wind that blows in the central part of the country and the Andes. These winds have been known to spread wildfires and cause extensive damage to property.

In addition to these strong winds, the country has suffered a number of earthquakes over the centuries as well as other natural disasters but visitors are no more at risk from the weather in Argentina than they would be in any other part of the Americas.
