Weather models suggest the UK could be heading towards its hottest day ever recorded, with forecasts indicating temperatures may climb above 40C and possibly reach 41C in parts of England during an extreme heat event expected in early July.
Extreme Heat Forecast Across England
New model data shows a major heatwave developing from 8 July, with temperatures rising quickly across southern and central England. Most areas are expected to exceed 30C, with highs of 33–34C forecast in Birmingham and the West Midlands early in the period.
By 9 July, temperatures could climb further, with southern England potentially reaching 37C and parts of Wales also seeing unusually high values for the time of year.
Potential Record-Breaking Temperatures
Forecast charts suggest that 10 July could bring extreme heat across much of England and Wales, with widespread temperatures between 37C and 39C. Western and southern regions are identified as the highest-risk zones for peak heat conditions.
By 11 July, some model outputs indicate temperatures could reach up to 41C in western England, which would surpass the current UK record of 40.3C set in 2022. If verified, such readings would mark the hottest day ever recorded in Britain.
Areas Most Affected By Heatwave
Birmingham and the West Midlands are shown within a broad corridor of extreme heat extending across western England, Wales and parts of southern central England. Large parts of Yorkshire and the south-east are also forecast to experience temperatures above 30C throughout the heat event.
The models suggest a widespread and sustained heat episode rather than a short-lived spike.
Recent Temperature Records Already Broken
The UK has already experienced record-breaking conditions this summer, with temperatures exceeding 37C during a recent heatwave. The country recorded its hottest June day on record, with temperatures rising on three consecutive days during the latest spell of extreme heat.
Met Office Outlook For July
The Met Office has said there is a higher-than-normal chance of further hot weather developing in July. However, forecasters also note the possibility of thundery showers during more unstable periods of the month.
Weather conditions are expected to remain highly variable, with alternating spells of heat and unsettled weather possible.
Uncertainty In Long-Range Forecasts
While model projections indicate extreme heat potential, long-range forecasts remain subject to change. Meteorologists continue to monitor evolving pressure systems that will determine whether temperatures reach the highest end of current predictions.
