Recent official forecasts from Argentina’s Servicio Meteorológico Nacional indicate a daytime high near 17–19 °C for Buenos Aires on October 11 under partly to mostly cloudy skies and light easterly winds, following a period of cooler, showery conditions on the 9th–10th. These readings align with springtime climatology for the region, where post-frontal southerly flow and residual cloud cover typically limit solar heating and keep maxima 1–3 °C below seasonal averages. Model consensus shows modest spread around these values, with any late-day clearing or wind shift potentially adding or subtracting a degree. Traders appear to weigh the official guidance against ensemble variability and historical October extremes, concentrating probability on the narrow 17–18 °C band ahead of the final observational window.
