Forecast models from sources including GFS indicate a daytime high of 28–29°C in Paris on September 29 under partly cloudy skies and light southerly winds, with minimal precipitation risk around 7%. This aligns with the market's leading outcomes at 28°C (48%) and 29°C (34.5%), reflecting trader consensus on modest warming from the prior day's rain-cooled conditions. Late-September climatology supports these values near seasonal norms, with clear model agreement on limited cloud cover permitting solar insolation and no major frontal systems expected. Updated runs show little deviation, though minor shifts in wind or cloud timing could adjust the peak by 1°C before resolution.
