Official Météo-France observations from the Paris-Montsouris station (WMO 07156), the authoritative reference for citywide records, confirm the lowest temperature on April 28 reached exactly 10°C during early morning hours amid clear skies and light northerly winds that limited radiative cooling. This aligns with pre-event forecast consensus from ECMWF and GFS models predicting mild overnight lows in a stable high-pressure system, elevated above April norms (typically 6–8°C) due to persistent warmth from prior days and urban heat island effects. Trader consensus at 100% implied probability reflects validated hourly data releases, with negligible risk of revision barring instrument malfunction—final quality checks occur within 24–48 hours post-event.
