**High pressure dominating southern England is sustaining a heatwave, with model consensus pointing to a peak of 32–33°C in London on August 14 after Thursday’s potential 36°C spike.** The Met Office currently forecasts a 32°C maximum under mostly sunny conditions, while other guidance shows slight variations around 33°C depending on the exact timing of any subtle cooling or increased boundary-layer moisture. Trader sentiment clusters tightly on these two outcomes because ensemble spreads remain narrow but include realistic scenarios for minor shifts in wind direction or thin high cloud that could trim or add a degree. Urban heat-island effects and the precise measurement station (typically Heathrow) add further uncertainty within that narrow band. New model runs and official updates through Friday morning will likely resolve the final degree.
