Current ensemble forecasts from Météo-France and ECMWF place Paris maximum temperatures on August 9 in the low-to-mid 30s Celsius, driven by high-pressure building over western Europe that favors clear skies, light winds, and strong daytime insolation following July's heatwave. Model spread centers on 30–34°C outcomes, with subtle differences in timing of any afternoon cloud development or boundary-layer mixing determining whether readings reach 33–34°C or stay near 32°C; climatological August highs average near 25°C, so this setup represents above-normal warmth. Traders assign roughly equal weight to the two leading bins as resolution nears and short-range guidance stabilizes, while lower-probability tails reflect residual uncertainty in urban heat-island amplification and exact steering flow.
