Current ensemble forecasts from major models indicate a minimum temperature in Paris on August 28 likely falling between 16–18 °C, supporting the closely matched market probabilities for 16 °C and 17 °C. A fresh southwesterly oceanic flow, combined with scattered showers and thunderstorms, is limiting daytime heating to around 23 °C while promoting modest overnight radiative cooling under variable cloud cover. Wind speeds near 15–25 km/h enhance boundary-layer mixing, which tends to prevent deeper drops below 16 °C, whereas partial clearing could allow brief radiational cooling toward 15–16 °C in sheltered areas. Historical late-August climatology shows average lows near 14 °C, but the current pattern reflects above-average warmth persisting into the weekend. Traders are closely watching the next model runs and any shifts in cloud or precipitation timing that could nudge the realized minimum by 1 °C.
