Recent forecasts from Météo-France and ensemble models show Paris transitioning out of a mid-August heatwave, with a cooler Atlantic air mass and increased cloud cover expected to limit daytime heating on August 20. This setup favors maximum temperatures near 24–25 °C, aligning with the closely matched market-implied odds. Key variables include the precise timing of any frontal passage and the extent of afternoon clearing, both of which can shift the daily high by 1–2 °C. Historical August baselines in Paris center around 24–25 °C, providing context for why traders see little probability mass above 26 °C or below 23 °C at this short lead time. Updated model runs and satellite observations over the next 48 hours will likely refine the final outcome.
