Summer in Argentina reaches its height in January, making this the ideal time to explore Patagonia and other parts of the country. However, as it is such a vast country, temperatures vary depending on where you go.

The central and northern parts of the country, including Buenos Aires, have a temperate climate. Thus, temperatures in these regions during January can be hot, reaching up to 29°C during the day. The north-eastern tip of the country, including Posadas and Correintes, has a tropical climate, with humidity levels soaring in summer, and there is always a risk of rain at this time of year. You will find much cooler temperatures in the south, such as in Patagonia, where it averages around 13°C during the day. Hence, January is also a great time to travel to Patagonia.

Since January is the peak month when it comes to Argentina, it can get pretty crowded, especially at famous spots like Patagonia. Even so, do not let the crowds deter you, as there are more reasons to be in Argentina during January than not.

  • National parks: Famous nature spots in the country like Parque Nacional Los Glaciares and Tierra del Fuego are located in the south, where the weather is mild and sunny. Rainfall during this month is at its lowest in these areas, and you do not have to worry about treacherous conditions.
  • Endless outdoor activities: Argentina sees up to 15 hours of daylight each day in January. This gives travelers a chance to choose from a vast selection of outdoor sports such as hiking, sailing, and kayaking.
  • Gualeguaychu Carnival: The city of Gualeguaychu hosts its renowned, two-month-long carnival in January and February, with dancers in colorful costumes parading through its streets each Saturday.
  • Beach time: Argentina’s beaches may not be as spectacular as the tropical coastline of Brazil. However, if you are looking to soak up the sun and escape the humidity, the beach resort of Mar del Plata is the place to be in January.
