Recent Met Office forecasts and ensemble models indicate a minimum temperature near 18°C in London on August 10, supported by a building high-pressure ridge delivering clear skies and light winds that limit nocturnal cooling. This setup favors overnight lows in the 17–19°C range, consistent with the closely matched market probabilities at those levels, while deviations hinge on subtle factors such as variable cloud cover reducing radiative heat loss or localized urban heat-island effects elevating readings by 1°C. Historical August minima average near 14°C, but the current warm anomaly—driven by above-average sea-surface temperatures and suppressed Atlantic fronts—shifts the distribution higher. Updated model runs and Met Office briefings over the next 48 hours will refine boundary-layer moisture and wind profiles, directly influencing resolution.
