Recent Met Office guidance points to a minimum of around 14°C in London on August 7 under partly cloudy skies and light winds, aligning with the market’s tight clustering around 14–15°C. Clearer nocturnal conditions would enhance radiative cooling and favor the lower end near 13°C, while increased cloud cover or a milder Atlantic air mass would limit overnight heat loss and support 15–16°C readings. London’s urban heat island further buffers extremes compared with rural sites. With the forecast window closing rapidly, the next model runs incorporating updated pressure patterns and cloud trends will likely sharpen trader positioning on these narrow thresholds.
