If they don’t know it already, travelers from the northern hemisphere will soon realize that the southern hemisphere’s seasons are completely reversed. Summer runs December to February; fall is March to May; winter is June to August; and spring is September to November.
Buenos Aires’ climate is generally pleasant, with an annual rainfall of 900mm spread evenly throughout the year. The changeable spring, hot and humid summer and mild fall resemble New York City’s seasons, but winter temperatures are moderated by the South Atlantic and – for a city with a relatively low latitude (34° 37’ S) – are more comparable to Los Angeles, Sydney or Cape Town.
Frosts are uncommon, and the lowest temperature ever recorded is -5.4°C (22.3°F). Snowfall is rare, but in 2007 a storm left the city covered in a thick layer of white – something that hasn’t happened since 1918.
When to go
In terms of weather, spring (September to November) and fall (March to May) are the best seasons to visit Buenos Aires. Also, most festivals take place during these months, as do a good chunk of sporting events. Winter can be cold but not freezing, and a fine time to visit the city’s theaters, museums and cafés.
Many tourists come during the late spring and summer (November to March), though the hottest months of January and February are usually unpleasantly humid. Porteños who can afford it leave the city for the coasts, so some places – like museums and entertainment venues – close down in the capital (January and February are also the worst months to be doing business here). However, no matter what time of year you visit, BA will have something exciting to offer.
