Recent ensemble forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) and Météo-France place Paris’s August 24 maximum near 25–27°C, with modest spread arising from uncertainties in cloud cover, boundary-layer mixing, and any weak frontal passage. After mid-August heatwave conditions that produced several days above 29°C, models indicate a gradual cool-down driven by increased Atlantic influence and northerly flow, keeping values close to late-summer climatology. The tight clustering of market-implied probabilities around 25–27°C mirrors this narrow forecast envelope, while lower odds for 28°C+ reflect limited potential for renewed subsidence or clearer skies. Updated model runs and 48-hour observational trends will further constrain the outcome before resolution.
