Recent Met Office guidance and ensemble model consensus point to a minimum of around 16°C in London on August 8, driven by light winds, limited nocturnal radiative cooling under partly cloudy skies, and residual warmth from a preceding high-pressure pattern that has kept overnight temperatures near or above seasonal averages. Typical August minima near 13–14°C reflect stronger clear-sky cooling and Atlantic air incursions, but current steering patterns and higher boundary-layer moisture are suppressing that drop. Traders weigh these variables against potential model shifts in the final 48-hour runs, particularly any increase in cloud cover or wind that could push the low lower or hold it near 15–17°C.
