What the numbers don't tell you
August is cool and dry, with afternoons around 17 °C, the Tango Festival and World Cup starting in the final week with free classes, concerts and the championship rounds, and San Martín Day on 17 August as a holiday. The first spring warmth appears late in the month. It is still quiet and cheap, and the milongas are packed with dancers in town for the championship. Rain falls on about six days.
The Children's Day on the third Sunday fills the parks. The polo season's Hurlingham and Tortugas Opens begin in September. Daylight grows from ten and a half to eleven and a half hours. For early spring and the Tango finals, see September.
