**Forecast consensus from the Met Office and multiple models points to a maximum of 21–23°C on August 31 in London, with 22°C as the most probable single value.** Westerly winds, partly cloudy skies, and isolated showers are expected to moderate temperatures near or slightly above the long-term average high of ~21.9°C for the date. Recent model runs show limited spread, with highs clustering around 70–72°F (21–22°C) under these conditions. The market's heavy weighting toward 22°C (46.5%) reflects this tight agreement across official guidance, while the shares for 21°C and 23°C capture residual uncertainty from exact timing of any cloud breaks or showers. Lower probabilities for 24°C or higher align with the absence of strong high pressure or southerly flow that could produce warmer outcomes. Updated forecasts in the next 24–48 hours, particularly from the Met Office, will likely refine these odds as the day approaches.
