**Official forecasts from the Met Office project a daytime maximum of 16°C for London on October 7 amid persistent rain, northerly winds, and an incoming cooler air mass that ended the prior warm spell.** This aligns with model consensus showing temperatures peaking near or below this threshold under overcast, wet conditions, supporting the 94% market-implied odds for 16°C. Recent days reached 21–23°C under clearer, southerly flow, but the shift to a more typical early-autumn pattern has stabilized expectations. Resolution depends on the highest verified reading at official stations; minor upward revisions remain possible if showers ease sooner than modeled, though current guidance indicates limited upside risk.
