Official measurements from Spain’s State Meteorological Agency (AEMET) recorded a daytime maximum of 35°C in Madrid on May 27 under persistent high pressure and clear skies that enhanced solar heating and minimized cloud cover. Ensemble forecasts had projected values near 34°C, yet actual observations aligned precisely with the upper end of model guidance amid above-average May warmth. This outcome matches historical patterns for late-spring heat under similar synoptic setups. The sole realistic challenge would involve post-event data revisions or station-specific discrepancies, though AEMET’s verification process makes such adjustments highly unlikely.
