Trader consensus on Polymarket closely splits between 26°C (37%) and 27°C (33.5%) for Madrid-Barajas Airport's highest temperature on April 6, reflecting ECMWF and GFS ensemble forecasts clustering around these values under a persistent high-pressure ridge fostering clear skies, light southerly winds, and efficient surface heating. AEMET's latest 7-day outlook projects a 28°C municipal maximum with 0% precipitation risk and minima near 13°C, but airport-specific model runs account for cooler boundary-layer effects at the site, differentiating the outcomes. Recent AEMET observations indicate rising highs to 21.4°C mid-week amid spring's above-normal warmth per seasonal guidance. Key uncertainties include afternoon convective cloud buildup and exact warm-air advection strength; updated model ensembles release April 5.
