Trader sentiment clusters tightly around 23–25°C outcomes for Buenos Aires' highest temperature today, reflecting uncertainty in short-term weather models amid a mild autumn pattern. The Servicio Meteorológico Nacional (SMN) latest guidance projects a daytime maximum near 23°C under mostly cloudy skies with scattered showers, moderated by southeasterly sea breezes from the Río de la Plata estuary. However, ensemble spreads from GFS and ECMWF models indicate potential for 24–25°C if afternoon cloud breaks enhance solar heating, consistent with yesterday's 23°C high. Key differentiators include timing of precipitation and wind shifts; persistent overcast favors 23°C, while clearer intervals boost higher readings. Monitor SMN hourly updates through late afternoon peak heating around 3–5 p.m. local time.
