Official observations from Météo-France's Paris-Montsouris station—the authoritative reference for Paris temperatures—confirm the highest temperature on April 10, 2026, reached only 16°C amid persistent cloud cover and a cool northerly airflow, aligning with pre-event ensemble forecasts from ECMWF, GFS, and Météo-France models that converged on maxima near 15–17°C. This outcome reflects early April climatological norms, with historical averages around 15°C, reinforced by overcast conditions suppressing solar heating. Trader consensus at 100% implied probability for "18°C or below" stems from this verified data, leaving negligible room for revision; only an unprecedented measurement correction from official archives could challenge it, though such events are exceedingly rare.
