Recent Met Office guidance forecasts a 26°C maximum for London on July 31 under persistent high pressure that favors mostly settled, dry conditions with light winds and variable cloud. This setup limits strong daytime heating compared with the 33°C recorded on July 29, producing a gradual cooling trend through the final weekend of July. Ensemble model spreads and local urban heat-island effects create the narrow gap between 25°C and 26°C outcomes that currently dominate trader probabilities, while the small chance of slightly higher readings hinges on clearer skies or delayed marine air influence. Official observations from central London stations will determine the exact daily maximum used for market resolution.
