Latest Met Office guidance and ensemble model consensus indicate a peak of 32–33 °C in London on 14 August, driven by persistent high pressure and warm southerly flow that has sustained the current heatwave. Minor variations in forecast highs hinge on subtle differences in boundary-layer mixing, afternoon cloud development, and the precise timing of any weakening in the ridge; these factors create the narrow spread between 31 °C and 34 °C outcomes. With resolution only 48 hours away, traders are weighting the most recent operational runs from the Met Office and ECMWF, which show limited scope for either significant cooling or further intensification before Friday.
