Buenos Aires Weather in March

Buenos Aires sits on the Río de la Plata estuary — one of the world's widest river mouths — which profoundly moderates the city's climate. The Pampero, a sudden cold wind from the southwest, can drop temperatures 20°F in under an hour. Summer (December–February) is hot and humid with averages around 84°F; winter (June–August) mild at 50–55°F. The Sudestada, a wet wind from the southeast, causes flooding in low-lying coastal neighborhoods.

Shoulder season — often good value with pleasant weather.

Buenos Aires has a humid subtropical climate — hot and sticky summers, mild winters, and moderate rainfall year-round. The Pampas winds can create dramatic temperature swings. The city is in the Southern Hemisphere, so seasons are opposite to North America/Europe.
