**Current forecasts from multiple models point to a cool, rainy day in Buenos Aires on October 3, with cloud cover and precipitation expected to cap daytime highs near 14–15 °C amid northeasterly flow.** A frontal system is bringing widespread rain and high humidity, limiting solar heating and keeping temperatures below the early-October climatological average of roughly 22 °C. Ensemble guidance shows limited spread but some uncertainty in exact maximum values depending on timing of heaviest rain and wind shifts. Traders appear to price modest upside risk from model variations or localized warming, resulting in the tight clustering around 15–17 °C outcomes. Official observations from the Servicio Meteorológico Nacional will determine resolution once the day concludes.
