Official Météo-France observations from key Paris stations, including Paris-Montsouris, confirm the highest temperature on March 28 reached exactly 11°C, driving trader consensus to a near-certain 100% implied probability. Persistent overcast skies and intermittent showers from a passing low-pressure system limited solar insolation and daytime heating, aligning precisely with pre-event ensemble forecasts from ECMWF and GFS models that clustered maxima around 10-12°C. This outcome sits slightly below the late-March climatological average of 12-13°C amid a regional cool anomaly over Western Europe. Post-observation validation is routine and highly reliable, with challenges limited to rare sensor recalibrations or data disputes, which official agencies resolve swiftly.
