**Forecast models from the Met Office and other agencies indicate a minimum temperature of 7–8°C in London on October 17, 2026, driven by clearing skies and northerly winds following Friday’s rain band.** This setup favors radiative cooling overnight, with early morning readings expected to bottom out near those levels under light winds and mostly clear conditions. Current consensus across GFS-based and official guidance aligns closely with the historical average low of about 8.5°C for the date, though the post-frontal air mass adds a slight downward tilt. Traders appear to weight 7°C and 8°C most heavily, reflecting model agreement on this narrow range while acknowledging minor uncertainty in exact timing of clearing or wind strength. Updated model runs and Met Office briefings over the next 48 hours will likely refine these probabilities ahead of market resolution.
