Latest ensemble forecasts from global models like ECMWF and GFS show Buenos Aires' March 22 high clustering tightly around 25°C, fueling the razor-thin trader consensus with 24°C (24.5%), 25°C (21.5%), and 26°C (21.0%) leading. Argentina's Servicio Meteorológico Nacional (SMN) projects a 26°C peak under partly cloudy skies and light southerly winds moderating earlier warmth, while historical data for March 22 averages 24.5°C at Ezeiza Airport, the likely measurement site. Key differentiators include model spread from potential sea-breeze intensification cooling to 24°C or lingering diurnal heating pushing 26°C; traders await afternoon convective risks in 12-hour updates, amplifying uncertainty in this autumnal shoulder-season volatility.
