Argentina experiences warm spell and showers as early‑July polar cold snap eases

In the first half of July, Argentina was hit by one of the strongest polar air incursions of the season, bringing extreme cold, widespread frosts, snowfall in the high Andes and wind gusts up to 90 km/h. Temperatures fell well below normal, with many regions recording record low minima.

Starting in mid‑July, meteorological models (ECMWF) forecast a marked warm air intrusion from the north. Temperatures are expected to rise 2–4 °C above seasonal averages across the central and northern provinces, with daytime highs reaching 20‑26 °C in areas such as Buenos Aires, Santa Fe, Entre Ríos, Córdoba and parts of the Pampas. The warmer, humid air will also bring a return of rain, ending a period of scarce precipitation and providing relief for agriculture. Forecasts call for isolated thunderstorms and showers in the AMBA, Santa Fe, Entre Ríos, Litoral and other regions through the weekend, while some isolated cold pockets and wind alerts (e.g., Zonda in San Juan) persist.

The overall trend signals a transition from the early‑month severe cold spell to a milder, wetter period that should reduce frost risk and improve soil moisture for the upcoming crop cycle.
