Ensemble forecasts from Météo-France and the ECMWF currently indicate Paris maximum temperatures of 34–36 °C on August 12 under a strengthening high-pressure ridge that favors clear skies, light winds, and efficient daytime heating. Southerly advection of warmer continental air combined with the urban heat-island effect supports the market’s leading 35 °C (48 %) and 34 °C (30 %) outcomes, while limited moisture and minimal cloud cover reduce the chance of significant cooling. Recent model runs show modest spread around these values, with upside potential to 36 °C if ridging intensifies and downside risk if a weak Atlantic front arrives earlier than projected. Updated guidance expected within the next 24–48 hours will likely narrow the range ahead of the August 12 observation window.
