Recent Met Office forecasts indicate settled high-pressure conditions over southern England, supporting a maximum of 22°C in London on August 24 with light winds and mostly clear skies allowing strong daytime solar heating. Ensemble model runs show narrow spreads around 21–23°C, driven by typical late-summer Atlantic flow and minimal cloud cover rather than any anomalous warm advection. The closely matched market odds for 21°C and 22°C reflect residual uncertainty in exact timing of any weak frontal approach or urban heat-island amplification, while lower probabilities for 24°C+ align with climatological August norms and absence of heatwave setup. Updated guidance expected within 24 hours could shift the balance.
