Trader consensus on Polymarket prices a 26°C high at 39.5% implied probability for Adolfo Suárez Madrid-Barajas Airport on April 5, reflecting AEMET's seasonal forecast of above-normal spring temperatures and recent ECMWF model runs projecting a persistent high-pressure ridge over Iberia, fostering clear skies, subsident warming, and highs in the mid-to-upper 20s°C. Early April observations at Barajas have trended warmer than average (nearing 21-22°C), aligning with climatological analogs for early-season heat under anticyclonic conditions, though historical April norms sit at 18-19°C. Forecast uncertainty remains, with ensemble spreads of 3-5°C; AEMET's next update on April 4 could shift odds ahead of Easter Sunday resolution.
