Recent forecast models from sources including GFS indicate a high near 15–16°C in Paris on October 8, driven by northwesterly flow and drier, cooler air following a frontal passage and rain on October 7. This positions 16°C as the market favorite at 56.5% implied probability, with 17°C a secondary option at 24.5%, reflecting typical autumn variability around the 17.8°C climatological average high. Traders weigh model consensus on daytime maxima under partly cloudy skies and moderate winds against minor uncertainties in exact peak timing or localized warming. Updated runs from official agencies will refine these odds ahead of resolution.
