Recent ensemble forecasts from the Met Office and ECMWF place London's maximum temperature on 18 August in the 24–26 °C range under partly cloudy conditions, with limited model spread and modest daytime heating beneath a weak ridge. This distribution underpins the tight clustering of market-implied probabilities around 24 °C (25.5 %), 25 °C (30.0 %), and 26 °C (23.0 %). Key differentiating factors include the precise timing of any Atlantic frontal approach, boundary-layer cloud cover, and local urban heat-island effects, all of which can shift the daily peak by 1–2 °C. Updated model runs and official guidance issued in the next 24–48 hours will refine these thresholds ahead of market resolution.
