Recent official guidance from Argentina’s Servicio Meteorológico Nacional and ensemble model runs show a high near 21–22 °C on October 6 under increasing easterly flow and cloud cover ahead of a weak front. This positions 22 °C as the narrow market favorite because modest differences in the timing of any partial clearing or slight warm-air advection from the north can add or subtract 1 °C at the daily maximum. Persistent low-level moisture and marine influence from the Río de la Plata limit stronger warming, while the modest precipitation risk keeps 23 °C or higher probabilities low. Updated model guidance and local observations over the next 48 hours will refine the exact peak.
