Recent forecasts from Météo-France and ensemble models position 31–33°C as the most probable range for Paris’s August 4 maximum, aligning with market-implied odds favoring 32°C. A transient ridge of high pressure is expected to yield partly cloudy skies and isolated showers that limit daytime heating, following hotter conditions near 35°C on August 3. Historical August climatology centers near 25–28°C, but the ongoing summer’s elevated baseline from repeated heatwaves has kept traders attentive to any model shifts in steering flow or boundary-layer moisture. Updated runs over the next 24–48 hours, particularly regarding precipitation timing and cloud cover, will likely determine whether probabilities tighten around 32°C or shift toward 31°C or 33°C.
