Extreme heat in Buenos Aires: temperatures to hit 38C on New Years Eve

Buenos Aires’s New Year’s Eve celebrations will take place in top temperatures, the Argentine weather service has warned. Since Monday, Buenos Aires City has been under an orange alert for extreme heat, the second highest alert possible. December 31 is forecast to be the hottest day of the year, with temperatures expected to reach 38°C. No rain is forecast, and the clear skies of recent days are set to continue. The National Meteorological Service has confirmed it’s not technically a heat-wave, which would require the scorching temperatures to continue for at least three days. Still, the orange alert is not one to ignore: it’s only issued when temperatures can have “moderate to high” effects on human health. It can be very dangerous, especially for at-risk groups. Buenos Aires won’t be the only part of Argentina feeling the heat. Areas in the provinces of Córdoba, Entre Ríos, western Buenos Aires, Santa Fe, and La Pampa are also on alert for high temperatures, although they’re only subject to a yellow alert, one step below the warning for the capital.
