Recent forecasts from Météo-France and supporting global models, including GFS runs, indicate Paris will reach a daily maximum of 28°C on September 6 under partly cloudy skies with light southeast winds. Afternoon observations and hourly data align closely with this value, consistent with seasonal norms around 23°C but elevated by current atmospheric conditions. Trader consensus at 100% implied probability for exactly 28°C reflects high confidence in official station measurements used for resolution. Minor variations in timing or localized urban heat effects could shift the recorded high by 1°C, though model agreement and real-time readings make significant deviations unlikely before final verification.
