Forecast models from Météo-France and international agencies indicate a daytime peak of 28–29°C in Paris on August 25, driven by gradual clearing of morning cloud cover and southerly flow that supports diurnal heating. Morning lows near 18–20°C under overcast skies with light showers give way to partial afternoon sun, allowing surface warming while elevated humidity and scattered thunderstorms cap further rises. Recent model runs show consensus around these values, with minor spread tied to exact timing of cloud breaks and wind shifts; historical August baselines for the region hover near 25°C, underscoring the current warmth. Traders price 29°C and 28°C highest because official guidance and real-time observations align closely with these thresholds before evening cooling begins.
