Trader sentiment clusters tightly around 25–27°C for Buenos Aires' March 25 high temperature, driven by the latest ensemble forecasts from Argentina's Servicio Meteorológico Nacional (SMN) and global models like ECMWF and GFS, which converge on 26°C amid lingering summer warmth in early autumn. Recent model runs indicate a ridge of high pressure building over the pampas, promoting sunny skies and afternoon convective heating that could push peaks 1–2°C above climatological norms of 24°C. Differentiation hinges on cloud cover uncertainty—partial overcast favors 25°C, while clearer conditions tilt toward 27°C—and diel temperature cycles, with SMN's 12Z update slightly favoring 26°C over competitors, reflecting low but nonzero spread in boundary layer forecasts. Upcoming 00Z runs may sharpen odds before resolution.
