Official observations from Spain’s AEMET network recorded a maximum of 39 °C in central Madrid on August 7, driven by a strong subtropical ridge, clear skies, and downslope warming that boosted surface temperatures well above the early-August climatological mean of 33–34 °C. Ensemble forecasts from ECMWF and AEMET had converged on this value days earlier, giving traders high confidence that the official reading would resolve the market at exactly 39 °C. A modest shift in station siting, an undetected instrumentation glitch, or a post-event data revision remains theoretically possible but is considered negligible given redundant station cross-checks and the narrow uncertainty range of the final report.
