Recent forecasts from agencies including the Met Office and Meteo France models converge on an overnight low near 19°C for Paris on August 26, driven by mild southwesterly flow, elevated humidity, and increasing cloud cover that limits radiative cooling after daytime highs around 28–29°C. Scattered showers expected overnight further moderate temperature drops by enhancing downward longwave radiation and reducing clear-sky heat loss. This positions 18–19°C as the market leaders, with small model variations in exact cloud timing and precipitation intensity creating the tight spread; historical August minima average near 14°C but recent warm anomalies have kept nights milder. Updated model runs and official briefings in the next 24–48 hours will likely refine these probabilities ahead of resolution.
