Official AEMET observations released April 8 confirm Madrid's highest temperature on April 7 was 22°C, with Barajas Airport station recording 22.4°C and Retiro at 21.5°C amid mild high-pressure conditions and light winds that capped daytime heating below initial ECMWF and GFS forecast peaks of 25°C. This precise alignment with verified hourly measurements from central weather stations has locked in trader consensus at virtually 100% implied probability for 22°C, reflecting the wisdom of crowds in aggregating skin-in-the-game data. While daily maxima are typically finalized post-validation, a realistic challenge would require late discovery or revision of an overlooked city station reading pushing 23°C or higher, though regional peripherals like Alcalá de Henares hit 24°C outside core Madrid boundaries.
