Recent forecasts from Météo-France and the ECMWF highlight a strengthening high-pressure ridge over northern France, delivering mostly sunny skies, light winds, and strong daytime heating that favor afternoon maxima of 37–38 °C in central Paris on August 13. These conditions build on an established heatwave, with Paris already reaching the mid-30s earlier in the week and overnight lows remaining elevated near 22 °C, limiting nocturnal cooling. Ensemble guidance places the highest likelihood in this narrow range, aligning with market-implied odds that concentrate volume on 37 °C and 38 °C outcomes while assigning modest probabilities to 39 °C or higher. Updated model runs over the next 24–48 hours will further constrain any late adjustments from marine-air intrusions or timing shifts.
