Trader consensus overwhelmingly favors 12°C as Madrid's highest temperature on March 21, driven by official AEMET observations confirming a midday peak of 12.2°C amid persistent northerly winds and cloudy skies suppressing daytime heating. ECMWF and GFS ensemble models had converged on this low-end outcome days prior, aligning with a broader cool anomaly over Iberia from stratospheric polar vortex influences. Historical March highs average 15–16°C, but this event mirrors 2023's chilly precedents. Realistic challenges include late-afternoon solar clearing or measurement revisions at Barajas Airport station, though low-probability southerly flow shifts faded per latest radar data.
