Trader consensus clusters tightly around 26-28°C for Buenos Aires' highest temperature on March 26, driven by ensemble weather model forecasts from GFS and ECMWF projecting daily maxima near 27°C under mild autumn conditions with weak southerly winds moderating heat. This reflects a 2-3°C spread in model outputs, influenced by variable cloud cover and potential sea breeze intensification, which could cap peaks at 26°C or allow urban heat island effects to push toward 28°C. Historical March averages hover at 25.5°C, but recent SMN updates indicate slight warming from high-pressure ridging aloft, heightening uncertainty and keeping lower (25°C or below) and higher (29°C+) outcomes as tail risks amid forecast divergence.
