Recent Met Office and ECMWF model runs show London under moderate easterly flow with partial cloud cover on August 24, limiting solar heating and capping daytime maxima near 21–23 °C. After early-August heat (peaks above 35 °C) gave way to cooler northerly then easterly regimes, current guidance clusters tightly around 22 °C, reflected in the near-even market odds for 21 °C and 22 °C. Key variables remain afternoon cloud fraction and boundary-layer mixing; stronger insolation or lighter winds could push readings to 23 °C, while increased low cloud or a slightly brisker breeze would favor 21 °C. Updated model cycles and observational trends over the next 48 hours will refine these thresholds ahead of market resolution.
