Trader sentiment clusters tightly around 17–20°C maximums for Madrid on March 27, reflecting ensemble forecasts from ECMWF and AEMET that project mild highs under a building high-pressure ridge over Iberia, with implied probabilities peaking at 18°C (27%) due to the median of 50+ member ensembles. Differentiating factors include subtle variations in southerly flow strength—warmer 19–21°C scenarios (37.5% combined) hinge on clear skies and föhn-like warming from the Sierra de Guadarrama, while cooler 16–17°C odds (38%) account for potential mid-level clouds or northerly shear per GFS perturbations. Historical March averages hover at 16°C, but anomalously dry soils and urban heat effects boost upside risk, with final AEMET updates expected by March 26 influencing late shifts.
