Recent European heatwave conditions, with France recording its hottest June day on record earlier this week and Météo-France issuing red alerts across much of the country, set the stage for Paris temperatures. Ensemble forecasts now show the primary cooling signal arriving Friday, June 26, as a weak front begins to moderate the heat dome, producing afternoon maxima most likely in the 35–38 °C range. Model spread remains modest but centers on whether the peak occurs before or after the frontal passage, explaining the tight clustering of market-implied odds around 36–38 °C. Updated runs from Météo-France and ECMWF expected in the next 24 hours will refine the exact timing and any urban heat-island amplification.
