Current forecasts from the Met Office and other models indicate a maximum of 21–22°C in London on August 22, driven by a mild maritime air mass under variable cloud cover and light northerly winds that limit daytime heating. Recent model runs show temperatures near or slightly below seasonal averages following earlier heat spikes, with consensus pointing to partly cloudy conditions that cap solar insolation and keep highs from reaching 23°C or higher. Trader sentiment clusters tightly on 21–22°C because ensemble guidance reveals modest uncertainty in exact cloud timing and any weak frontal passages, while historical August maxima in London average near 22°C. Updated short-range model outputs and satellite observations over the next 48 hours will likely refine the peak reading used for market resolution.
