Current Met Office guidance points to a 17°C overnight minimum for London on July 27 amid a moderating air mass after earlier July warmth, with ensemble models showing modest spread around that value. Traders favor 15–17°C outcomes because typical late-July radiative cooling under partly cloudy skies and light winds often produces lows near the 14–16°C climatological baseline, while any increase in cloud cover or stronger mixing could hold temperatures a degree or two higher. Short-range model updates from the Met Office and ECMWF remain the key near-term catalysts, as even small shifts in predicted wind or humidity can alter the precise minimum by 1–2°C before resolution.
