Official observations from the Paris-Le Bourget Airport station (LFPB), as reported by Weather Underground and aligned with Météo-France METAR data, confirm the highest temperature on April 19, 2026, peaked at 18°C, solidifying trader consensus at 100% implied probability. Partly cloudy skies, light northerly winds, and high pressure over northern France capped daytime heating, matching pre-event ECMWF and GFS ensemble forecasts of 17-18°C amid slightly above-average spring conditions (monthly Paris max average ~18.7°C). This positioning reflects low uncertainty in finalized hourly records, with historical mid-April highs in the region typically 15-18°C. Realistic challenges would require rare post-quality-control data revisions at the resolution station.
