What is the overall climate: is it extremely hot or cold, wet or dry, at any time of year, for example?
Four seasons, just opposite the times of the Northern Hemisphere. Summer is very hot and humid in January and February. Winter is pretty mild and rainy. It doesn't really snow here in Buenos Aires. - Jul 2019
Four seasons with a mild winter. - Jun 2015
I was only here for a short time in winter so I can't speak a lot about it. It was mostly pretty reasonable although it could get pretty cold a few days. Spring was fantastic - picture cloudless sunny days around 65-75F degrees. Summer can get really hot but it's not as hot as a lot of people warned me about. It's pretty pleasant 3 out of 4 days, and the fourth day can be pretty uncomfortably hot and humid. Anyone who is familiar with the Southeast of the U.S. will probably agree that the climate here is pretty similar. I think NC was hotter than Buenos Aires though. - Jan 2015
4 seasons with winter lasting from June to September. Lots of expats avoid winter weather by returning to the States during this time with their school-age kids. - Aug 2014
Very mild, never freezes. - Aug 2011
Reverse seasons. Summer Dec-March with highs in the mid 80s. Mild winters June-Aug. Spring and fall are wonderful. - May 2011
Winter tends to be rainy and grey, especially July & August but not that cold (average in the high 40s). Spring/Fall are beautiful, summers are usually in the high 80s and humid. Most people try to leave the city in January for the beach or countryside. - Jul 2008
