Latest Met Office guidance forecasts a maximum of 27°C for London on July 4 under building high pressure and a southerly airflow, while ensemble runs from ECMWF and GFS show a tight cluster around 26–29°C with modest uncertainty from cloud timing and boundary-layer mixing. The 27°C and 28°C outcomes lead because modest insolation and light winds favor peak readings near the seasonal July average of 22–23°C, offset by recent warming trends after June’s heatwave. Differentiation among these bins hinges on small variations in 850 hPa temperatures, urban heat-island enhancement at official sites, and any late-afternoon sea-breeze effects that could cap readings at 26°C or allow brief spikes toward 29°C.
