Official AEMET observations from the Adolfo Suárez Madrid–Barajas Airport station—the authoritative source for market resolution—confirm the highest temperature on April 27 reached 27°C, rounded from precise 10-minute averages amid clear skies and a persistent high-pressure ridge over Iberia fostering mild advection of warm continental air. This aligns with leading forecast models like ECMWF and AEMET's own guidance, which projected peaks of 26–27°C under light easterly winds and abundant sunshine, consistent with above-average spring warmth (historical April highs average 18–20°C). Trader consensus at 100% implied probability reflects this verified measurement, with negligible risk of revision barring rare quality-control anomalies in preliminary data; final AEMET daily bulletin expected within 24 hours.
