High season in Buenos Aires runs September to May, or South America’s spring through fall. It peaks December through February, which also coincides with the city's dog days of summer. The humidity and heat climb, and though Buenos Aires is located along the Rio de la Plata, it is necessary to leave the city to get on the water, and many people do. Most locals skip off to beach destinations along the Argentine coast (Mar del Plata, Pinamar) or over to Uruguay’s beaches like the well heeled Punta del Este. If people stay for work they leave for the weekends, and a number of local businesses close for a month or so, including restaurants and bars. Visitors who arrive in October and November can see Buenos Aires at its most beautiful when the bright violet buds of jacaranda trees lining the city’s streets and parks are in full bloom.
