Forecast models from sources including Météo-France and ECMWF indicate a maximum temperature near 22–23°C in Paris on August 29, driven by persistent cloud cover, scattered showers, and moderate southwesterly winds that limit daytime heating below the late-August climatological average of 24°C. These conditions create tight differentiation between the leading outcomes, as modest shifts in cloud thickness or rainfall timing could add or subtract 1°C through reduced insolation or evaporative cooling. Surface pressure around 1012–1014 hPa and dew points near 15–17°C further support this range, with minimal risk of reaching 24°C or above absent rapid clearing. Traders weigh recent model consensus against historical variability on this date, where highs have ranged from 15–34°C, while monitoring any afternoon updates from official stations.
