Current numerical weather models, including GFS outputs, indicate an overnight low near 19°C in Paris under mild late-summer conditions with extensive cloud cover, light southerly flow, and dew points supporting limited radiative cooling. This aligns with observed temperatures holding above 18°C through the evening and historical analogs for the date showing average minima around 14–17°C. Trader consensus at 19°C reflects convergence across ensemble forecasts and real-time station data, with only narrow uncertainty from potential shifts in cloud timing or wind speed. A realistic challenge would require an unexpected clear-sky period or stronger northerly advection to push the minimum toward 16–17°C, though current observations and model consensus make larger deviations unlikely before final resolution.
