Official Météo-France observations from the Paris-Montsouris meteorological station—the authoritative reference for citywide records—confirm the highest temperature on April 3, 2026, peaked at 13°C around midday, solidifying trader consensus at virtually 100% implied probability for this outcome. Persistent stratus cloud cover and a cool northerly airflow, as forecasted by ECMWF and French models, limited solar heating despite light winds, keeping readings below seasonal norms of 14–15°C for early April. This aligns with hourly data showing maxima in the low teens amid overcast skies. Scenarios challenging this would require rare post hoc data revisions from official sources, such as an overlooked urban heat outlier, though validation processes make such shifts improbable; final bulletins expected within 24 hours.
