Argentina’s summer high season falls in January and February. Temperatures are hot and humid, often reaching the mid-90s. If you come the first two weeks of January, many of the locals have left for summer vacation, hitting the beaches of Argentina and neighboring Uruguay. Nonetheless, this is when hotels have their highest occupancy rates and prices. In February, the city hosts Fiesta de las Murgas, BA’s version of Mardi Gras.
Springtime in Buenos Aires is a special season, with temps lingering in the mid-70s. Not only are the jacaranda trees in resplendent purple bloom in October and November, but the city also hosts two of its best festivals. In early to mid-October, the World Tango Festival comes to San Telmo. In late November, the Las Cañitas neighborhood plays host to the largest polo event in the world, the Argentine Open Polo Championships.
June and July can be cold and rainy, though it rarely snows in Buenos Aires and the temperatures usually stay above 40 degrees, even reaching 60 degrees during the day. If you’re in town in late August, catch Buenos Aires Fashion Week, which features the upcoming summer collection.
