Recent forecasts from models including ECMWF and GFS indicate a mild southerly to westerly flow advecting warmer Atlantic air over northern France, supporting daytime highs of 23–25°C in Paris on October 13. This places temperatures 4–7°C above seasonal normals, with afternoon peaks most likely between 23°C and 24°C amid variable cloud cover and possible light showers that could limit solar heating. Ensemble spreads remain narrow, reflecting modest uncertainty in exact timing of any frontal passage or wind shifts, which traders have priced into the tight 23°C–24°C contest. Official Météo-France observations at the close of the calendar day will resolve the market.
