Latest Met Office guidance points to a 28°C maximum in London on August 10 under building high pressure, with prolonged sunshine and light winds favoring strong daytime heating. Ensemble forecasts, however, show a spread that includes modest Atlantic moisture or increased cloud cover, which could cap the peak 1–2°C lower. Traders have therefore assigned the highest implied probabilities to 26°C and 27°C, reflecting uncertainty in how quickly any residual frontal influence or sea-breeze effects might arrive on the day. Historical August maxima near 27°C provide context, while the official resolution will hinge on the precise recorded high at designated London stations.
