Climate

A temperate and sunny climate makes BA a great destination at any time of the year.

We're ready to welcome you all year round.

  • With average temperatures of around 18ºC (64°F), Buenos Aires is blessed with a temperate and sunny climate, making it a great destination at any time of the year.
  • July is the coldest month, and although we don't get frost or ice in Buenos Aires, a few warm layers are recommended if you come to visit mid-year, particularly for going out at night.
  • The summer months of January and February can be somewhat humid and it remains warm at night, so bring fresh, light clothing. 
  • Spring and autumn are the rainiest seasons. Rains tend to be light and don't get in the way of activities but you may want to bring a raincoat or umbrella.

Climatic phenomena

  • Veranito de San Juan: around 24 June (date of the birth of Saint John the Baptist), it's not unusual for temperatures to rise to up to 24°C (75°F) for several days. Be prepared to see winter sunbathers sunning themselves in parks and plazas.
  • Tormenta de Santa Rosa: Around 30 August (festival of Santa Rosa), electrical storms and heavy rainfall often signal the end of winter and the approach of spring.
  • Snow: OK, so it’s only happened twice in recorded history (22-23 June 1918 and 9 July 2007), but it got us excited.
