Recent official forecasts from Argentina’s Servicio Meteorológico Nacional indicate a high of 18°C for Buenos Aires on October 1 under variable cloud cover, light winds shifting southerly, and no precipitation, following several days of storms and cooler air advection. International models cluster between 17–19°C, with differences driven by the precise timing of cloud breaks and boundary-layer mixing that can add or subtract 1–2°C from peak readings. Historical early-October averages near 19–20°C provide context, yet the current pattern favors slightly suppressed maxima. Traders assign the highest implied probabilities to 16–17°C outcomes because forecast uncertainty remains elevated this close to the date, with new model runs and SMN updates expected to refine the exact peak before resolution.
