Recent forecasts from the Met Office and other models indicate a maximum temperature in the low-to-mid 20s Celsius for London on September 4, with afternoon readings likely peaking near 23–24 °C amid westerly winds, variable cloud cover, and a chance of showers that could limit daytime heating. Ensemble guidance shows modest spread driven by the precise timing of any rain bands and the degree of clearing, keeping the most probable outcomes tightly clustered between 22 °C and 24 °C. Trader sentiment reflects this narrow scientific uncertainty, with implied probabilities favoring the central values while assigning lower weight to outliers above 25 °C or below 21 °C that would require atypical model shifts. Updated runs ahead of the event will further refine the expected peak.
