Official AEMET observations from Madrid's primary meteorological stations, including Barajas and Ciudad Universitaria, confirmed a peak temperature of 28°C on April 10, 2026, solidifying trader consensus at virtually 100% implied probability for this outcome. This matched closely with pre-event forecasts from AEMET models anticipating highs near 28°C under a stable high-pressure ridge promoting clear skies, light winds, and ample solar heating—conditions warmer than the typical April average of 18–20°C but consistent with recent days' trend of 27–28°C peaks. Post-event data validation leaves minimal uncertainty, though a rare sensor recalibration or quality control revision could theoretically adjust the record if an anomaly emerges. Traders await no further updates as the market nears resolution.
