Latest GFS and ECMWF ensemble runs project daytime highs of 28-31°C in Buenos Aires on March 29, propelled by a persistent upper-level ridge advecting warm subtropical air masses well above the late-March climatological average of around 25°C, concentrating trader consensus on 28-30°C outcomes with implied probabilities of 18-26%. The tight race reflects model spread in afternoon cloud development that could curb peak insolation, moderating influences from Río de la Plata sea breezes potentially trimming 1-2°C off maxima, and urban heat island amplification at Aeroparque station under light winds. Servicio Meteorológico Nacional forecasts align near 30°C with isolated storm risks, but new 12Z model cycles and SMN updates tomorrow may sharpen resolution amid inherent short-range forecast uncertainty.
