Latest Met Office and ECMWF ensemble forecasts for London on June 15 point to a daytime maximum near 22–23°C under a transitional post-heatwave pattern, with light southerly winds, variable cloud, and limited insolation preventing further warming. This follows an exceptionally warm May that shifted the jet stream and allowed cooler Atlantic air to influence southern England, keeping values close to the long-term June average of about 20–21°C. Trader consensus, reflected in the tight 31.5% and 29% probabilities for 23°C and 22°C respectively, incorporates model spread on exact cloud timing and urban heat-island effects, while the modest 18.4% share for 24°C or higher acknowledges residual uncertainty in any late-day clearing.
