Recent meteorological guidance from sources including Météo-France ensembles and ECMWF runs points to a daytime maximum of 23–24 °C in Paris on 22 August, driven by moderating Atlantic airflow, increased cloud cover, and scattered showers that suppress peak insolation. This follows an early-August heatwave that produced readings above 33 °C before a progressive cooldown of 5–8 °C over the past week. Late-summer climatology places the average high near 24–25 °C, so the current pattern sits slightly below normal. Short-range model consensus remains tight on the 22–24 °C range, with only modest uncertainty from the precise timing of any convective cells; traders have therefore concentrated probability on those two bins while assigning negligible weight to extremes above 26 °C or below 21 °C. Updated forecasts through the weekend are expected to further refine these implied odds.
