Trader consensus on Polymarket favors a highest temperature of 13°C (38.5% implied probability) for Madrid on March 29, driven by the latest AEMET forecast projecting a maximum of 14°C and ECMWF ensemble means centering near 13°C amid northerly winds advecting cooler continental air over the Iberian Peninsula. This marks a dip from recent observations—19°C maximum at Madrid-Retiro on March 27 and a forecasted 20°C peak today (March 28)—due to a transitional high-pressure pattern limiting solar heating under partly cloudy skies with NE winds at 15 km/h and no precipitation risk. Ensemble spreads capture uncertainty between 12–14°C, below the late-March climatological average of 17°C, with final resolution hinging on AEMET's official Retiro station data; watch evening model updates for potential refinements.
