Trader consensus clusters around 20-21°C for Madrid's March 25 high, driven by the latest ECMWF and GFS ensemble forecasts projecting peaks of 20-22°C under a persistent high-pressure ridge over Iberia, funneling mild southerly flows. AEMET's official outlook aligns at 20°C maximum, buoyed by above-normal geopotential heights but tempered by potential afternoon cloud incursions from an approaching Atlantic front. Differentiating factors include subtle model spreads: warmer 22-23°C runs hinge on sustained clear skies, while 18-19°C risks rise if frontal timing accelerates, per historical late-March volatility when averages hover near 17°C. Upcoming 12-hour updates could sharpen odds.
