Official Météo-France observations from key Paris stations, including Montsouris and Charles de Gaulle Airport, confirm the highest temperature on March 27, 2026, reached exactly 11°C amid persistent cloud cover, light northerly winds, and cool air masses over Île-de-France. This aligns with pre-event forecasts from ECMWF and GFS models, which projected maxima around 11-12°C due to atmospheric blocking patterns suppressing warming. Trader consensus at 100% implied probability on 11°C reflects this verified observational data, representing the gold standard for meteorological records. Realistic challenges, such as rare post hoc data revisions from quality control or disputes over station representativeness, are improbable given the multi-station agreement and standard resolution criteria.
