Recent Météo-France and European model forecasts position Paris’s August 18 maximum near 26–27°C, driven by stable high pressure, modest southerly warm-air advection, and partly cloudy skies that limit intense daytime heating. These conditions align with typical mid-August climatology for the region, where average highs range 24–26°C absent heatwave setups. Trader consensus, reflected in the 45.5% implied probability for 26°C and 27.5% for 27°C, incorporates the latest model runs showing limited upside potential and only modest overnight recovery, with lower outcomes (25°C or below) holding 21.5% amid any increased cloud cover or precipitation risk. Updated guidance through the day will refine these probabilities ahead of official observations.
