Forecast consensus from numerical models and meteorological agencies points to a daytime high of 23–24°C in Paris on October 13 under mostly cloudy skies and moderate southwesterly flow. These conditions limit solar heating while advecting relatively mild maritime air, keeping temperatures above seasonal norms but below thresholds for stronger warming. Traders have priced 24°C as the clear favorite at 59.2% implied probability, reflecting tight model agreement and the day’s advanced stage, with only modest odds on 25°C+ or 23°C reflecting residual uncertainty in exact peak timing and urban heat island effects. Official observations expected later today will resolve the market.
