Updated short-term forecast models from the Met Office and ECMWF indicate a likely maximum of 25–27°C in London on August 1, driven by a mix of Atlantic airflow and variable cloud cover that limits surface heating while keeping conditions above seasonal averages. Recent model runs have converged on this range after earlier projections of potential 30°C+ heat were tempered by incoming fronts, reducing peak solar insolation and capping diurnal rise. Trader consensus reflected in the 56.5% implied probability for 26°C and 28.5% for 25°C aligns with these guidance trends and historical August baselines, though ensemble spread and timing of any late clearing introduce modest uncertainty around exact resolution.
