Trader consensus on Polymarket strongly favors 18°C as Madrid's highest temperature on March 22, with 37.5% implied probability, driven by the latest ECMWF and GFS ensemble forecasts projecting peaks of 17-19°C under a persistent high-pressure ridge over Iberia. AEMET's official outlook aligns, citing mild continental air masses and light northerly winds capping highs after recent frontal passages that boosted soil moisture and moderated warming. Climatological norms for late March average 17.5°C, with current neutral ENSO conditions minimizing outlier risks; 19°C trails at 26% amid minor model spread, while extremes below 16°C or above 20°C see slim odds below 5% due to absent heat dome or cold outbreak signals. Watch AEMET's next update for intraday refinements.
