Trader consensus on Polymarket heavily favors a Madrid high of 17°C (38%) for March 26, driven by the latest AEMET and ECMWF model runs projecting mild spring conditions under a persistent high-pressure ridge over Iberia, with forecasted maxima clustering at 16-18°C. Recent observations show March 25 highs around 16°C amid light southerly winds and partial cloud cover, aligning with seasonal climatology where late-March averages hover near 16.5°C but recent mild anomalies have nudged odds toward 17-18°C. Lower probabilities for extremes reflect low volatility in current synoptic patterns, with no signals of heatwaves or cold snaps from GFS ensembles; watch AEMET's evening update for potential refinements as diurnal heating thresholds firm up.
