When planning your trip to Buenos Aires, keep in mind that the seasons are reversed in the southern hemisphere. Summer starts in December; winter starts in June. The summer vacation months in Argentina are January and February: school is out and families travel.

As for weather temperatures, expect mild and temparate winters, and humid and hot summers.  Three or four times a year there are 3-4 days periods in which it can get very cold.It rarely snows in Buenos Aires but the summers can at times be unbearably hot with a lot of thunderstorms, specially from late December to mid February.
