Forecast models from agencies like the Servicio Meteorológico Nacional and international ensembles indicate overnight radiative cooling under mostly clear skies and light easterly winds will drive Buenos Aires minimum temperatures into the 5–8°C range on August 28. Late-winter conditions with dew points near 7–9°C and minimal cloud cover support efficient surface heat loss after sunset, while stable high pressure limits mixing. Slight differences in model timing of any weak frontal passage or wind variability create the tight clustering of market probabilities around 6–8°C, with lower outcomes possible if cooling extends longer than expected. Updated model runs and official minimum observations will refine resolution criteria as the night progresses.
