Latest short-range forecasts from the Servicio Meteorológico Nacional (SMN) and ensemble guidance from ECMWF and GFS models project a daytime high near 18-19°C in Buenos Aires on May 15 under clear to partly cloudy skies, reflecting trader consensus in the closely matched 17-20°C outcomes amid typical mid-autumn cooling trends. Differentiating factors include variability in cloud cover reducing solar insolation, potential sea breeze moderation from the Río de la Plata, and light southerly winds limiting diurnal warming, with urban heat island effects at the official Ezeiza Airport station adding ~1°C. Historical May 15 highs average 18°C with a 2-3°C standard deviation, underscoring inherent forecast uncertainty; new SMN updates and 00z model runs expected overnight could refine the peak temperature trajectory.
