Trader consensus on Polymarket heavily favors 17-19°C as Madrid's highest temperature on March 28, with 18°C leading at 29.5% implied probability, reflecting tight alignment in latest ensemble forecasts from ECMWF (mean ~18°C) and GFS (17-19°C spread), corroborated by AEMET's official prediction of 19°C under persistent high-pressure ridge over Iberia. Recent model runs show slight cooling from earlier 20°C+ projections due to increased northerly flow moderating warmth, while historical late-March baselines average 15-16°C at Madrid-Barajas station. Differentiating factors include urban heat island effects potentially edging toward 19°C and short-term cloud cover variability, with uncertainty from 24-hour forecast divergence keeping lower outcomes viable.
