Recent forecasts from Météo-France-aligned sources and global models such as GFS converge on a maximum of 32–33°C in Paris on September 15, driven by southerly to southwesterly flow advecting warmer air and mostly clear to partly cloudy skies that favor strong daytime insolation. This setup places readings 8–10°C above the 1991–2020 climatological average high of 21.6°C, with minimal cloud cover and negligible precipitation risk supporting peak heating during afternoon hours. Ensemble consistency across runs has tightened implied probabilities around 32°C, though minor model spread on exact wind direction and boundary-layer mixing leaves room for a 31°C or 33°C outcome depending on final steering and local urban effects. Updated model guidance expected overnight will further refine resolution criteria for the daily maximum.
