Recent forecast guidance for Buenos Aires on September 2 points to a minimum near 10–12 °C, driven by northerly flow advecting milder air ahead of a weak front, combined with partial cloud cover limiting overnight radiative cooling. Model consensus shows daytime highs reaching 20–22 °C under partly cloudy skies, while the nocturnal boundary layer is expected to bottom out near the seasonal climatological average of roughly 11 °C. Uncertainty in exact low temperatures stems from small differences in wind speed, dew-point depression, and timing of any scattered showers, which can alter the rate of surface cooling by 2–3 °C. Traders are weighing these variables against historical September minima, resulting in tightly clustered probabilities across the 7–13 °C range. Updated model runs and official Servicio Meteorológico Nacional guidance over the next 24–48 hours will likely refine the resolution threshold.
