Current forecasts from the UK Met Office and supporting models indicate a minimum temperature near 18°C for London on August 14 amid an ongoing heatwave, with daytime highs reaching 31–32°C under high pressure and mostly clear skies. This setup favors limited radiative cooling overnight, potentially elevating the daily low into the upper teens to low 20s depending on cloud cover, wind speed, and urban heat retention. Ensemble model spreads and slight variations in timing of any incoming Atlantic moisture create the tight clustering around 21–23°C outcomes, as traders weigh the balance between heat advection and typical August nocturnal drops. Updated model runs and Met Office briefings over the next 48 hours will likely refine these probabilities ahead of resolution.
