**Forecast consensus from models and the Met Office points to a daytime maximum near 16°C in London on October 7, 2026, as the dominant outcome.** Northerly winds advecting cooler maritime air, combined with widespread cloud cover and showers, limit solar heating and keep temperatures suppressed relative to the prior day's 21–22°C peak. These conditions align with typical early-October climatology while the active frontal passage adds further cooling. Traders assign 84.5% implied probability to exactly 16°C and 15% to 17°C, reflecting tight clustering around official guidance and low likelihood of outliers given the established synoptic pattern. Real-time observations through the afternoon will refine the final recorded high.
