What the numbers don't tell you
March is the start of autumn and the return of normal life, with schools back, afternoons around 26 °C, Lollapalooza at the San Isidro racecourse over a weekend in March and Memorial Day on 24 March, a solemn public holiday with a march to Plaza de Mayo. Days are warm and the humidity drops. It is one of the best months, with the city at full cultural capacity. Rain falls on about eight days.
The Colón's season opens, and the Malba and the Bellas Artes museums run their autumn shows. The polo at Palermo begins its autumn tournaments. Daylight shrinks from thirteen hours to twelve. For the mild, golden month with the Book Fair opening, see April.
