When to go by Season
November to February
The summer months are a popular time to visit, particularly between the peak season between Christmas and New Year which requires early booking to guarantee availability. Being so close to the Antarctic, the southernmost reaches of Argentina around Ushuaia are more suited to travel during this time, when the temperature can reach a comfortable 16°C or 60°F. The north of the country experiences the hottest weather during this time.
March to April
Autumn can be an ideal and temperate time to visit most of country. In Patagonia, it marks the onset of winter albeit before the coldest months set in. It is also a great time to visit Buenos Aires and the Lake District, which feels distinctly fresher outside of peak summer and winter.
May to August
During the winter months, many of Patagonia’s key attractions are closed and the northern areas of the country are amongst the best to visit, such as Iguazu Falls or Salta, where you are likely to experience mild temperatures of around 12°C or 56°F.
September to October
As with autumn, the spring months can be an ideal time to visit most of the country the Lake District around Bariloche, as well as Patagonia and the capital of Buenos Aires, which can become unbearably hot in the height of the summer.
