Recent cool, rainy conditions driven by southerly winds have suppressed temperatures in Buenos Aires ahead of October 10. Official forecasts from multiple models project a daytime high near 16°C and overnight low of 11–13°C under continued cloud cover and showers, consistent with a cooler-than-average early spring pattern. Southerly flow and high humidity favor radiative cooling at night but limit sharp drops, while any clearing could allow slightly lower minima. Historical October lows average around 13°C, providing context for the current outlook. Trader consensus near 49% for both sub-8°C and 17°C+ extremes, alongside 33–34% on 11–16°C outcomes, reflects model spread in timing of any frontal passage and variable cloud effects on minimum readings. Updated National Meteorological Service guidance and next model runs will refine resolution thresholds.
