Current forecasts from multiple models show Paris reaching a peak of 31–32°C on September 15 under clear skies, southwest flow, and light winds that favor strong daytime heating, driving the market’s 50.5% implied probability on 32°C. This represents a notable positive anomaly relative to the 21–22°C climatological average for the date. Recent model runs have stabilized around these values with minimal disagreement, though minor shifts in timing or cloud cover could alter the exact maximum by 1°C. With resolution imminent, traders are weighting the latest official guidance heavily, while the spread to 31°C and 33°C at 20.5% each reflects residual uncertainty in final observed readings.
