Recent forecasts from the Met Office and other models indicate a high of 25–26°C in London on August 5, driven by a shift to cooler, breezier conditions with sunny intervals following earlier heatwave peaks. This aligns with historical August averages near 23°C and reflects typical post-heatwave moderation from Atlantic influences. Trader consensus on these thresholds as leading outcomes stems from consistent model runs showing limited daytime heating under moderate winds, with minimal risk of exceeding 27°C or dropping below 24°C absent major forecast revisions. Upcoming official observations from urban stations will resolve the market, underscoring how short-term atmospheric steering patterns shape these implied probabilities.
