Trader consensus on Polymarket reflects the tight clustering of ECMWF and GFS ensemble forecasts for Madrid's highest temperature on April 4 at 22–24°C, driven by a mild high-pressure ridge building over Iberia after recent cool maxima around 11°C at Adolfo Suárez Madrid-Barajas Airport. AEMET's latest outlook aligns, projecting up to 25°C under mostly clear skies and light northerly winds at 15 km/h, enabling strong daytime insolation on this spring day when historical April averages hover near 18°C. Differentiating factors include subtle ensemble spreads: ECMWF leans slightly cooler at 23°C due to potential afternoon high-cloud intrusion, while GFS control runs favor 24–25°C with sustained subsidence; genuine uncertainty persists in exact ridge positioning and boundary-layer mixing. Watch AEMET's next update and real-time airport observations for resolution.
