  • Hazard

    Summer heat and humidity

    1 Jan – 25 Feb · usuallyExtreme heat

    River-plate humidity on top of the heat, and the porteños who can afford to have gone to the coast. Museums and cafés run cold; walking Palermo at three in the afternoon does not work. Source ↗

    Two public holidays and murga groups drumming through the outer neighbourhoods rather than the centre. It is a local, suburban carnival, not a Rio-scale one, and much of the city takes the long weekend away. Source ↗
