Consensus forecasts from Argentina's Servicio Meteorológico Nacional (SMN) and global models like ECMWF and GFS project Buenos Aires' highest temperature on March 28 at 27-29°C, fueling 65.5% market-implied odds for 27°C or higher amid a persistent high-pressure ridge amplifying autumn warmth. Recent ensemble runs updated overnight show tighter clustering around 28°C, boosting trader confidence while 19.5% odds for exactly 26°C reflect outlier cooler projections from UKMET amid sea-breeze risks. March climatology averages 24°C maxima, but antecedent heat on March 27 (observed 26°C) and low wind shear favor the warmer outcomes, with final SMN update expected midday.
