A 72-hour Antarctic cold front is coming, bringing freezing temperatures, rain and winds of up to 100 km/h

Although meteorological spring has begun, a powerful Antarctic cold front will bring Argentina several days that feel like midwinter. The system will enter from Patagonia and progressively move toward the country’s central and northern regions during the first weekend of September.

The polar air will bring severe frosts, rain, scattered showers, unusual snowfall and wind gusts above 50 km/h. In some parts of the Andes, gusts could reach 100 km/h. Temperatures on the Patagonian plateau could fall to -13°C, with daytime highs remaining below zero in some areas.

The coldest period is expected between the night of Saturday, Sept. 5, and the early hours of Sunday, Sept. 6. Frost will spread across the Pampas and Argentina’s core agricultural region. Buenos Aires could record temperatures close to 2°C, while parts of the greater metropolitan area could reach or dip below 0°C.

The front is expected to intensify over Patagonia on Saturday before moving toward central and northern Argentina. The far south may remain relatively stable, but coastal areas, particularly eastern Chubut and Río Negro, could see intermittent rain and showers. In the northwest, strong winds remain a concern, with gusts of up to 100 km/h at higher elevations and Zonda winds possible in parts of Jujuy and Salta.
