Weather forecasting models indicate that the UK could experience its hottest day of the year so far next week, with temperatures potentially surpassing 37C in eight counties.
Forecast models show potential highs
The current temperature record for 2026 stands at 37.7C, recorded on June 26 in Lingwood, Norfolk. However, data from the GFS weather model suggests temperatures could rise past 37C again next week.
According to the model, maximum temperatures could reach 34C on Wednesday next week in southern England, in an area stretching from Gloucestershire to Surrey. South Wales could see 31C, while the Midlands may rise to 33C.
Possible heatwave conditions
On Thursday, highs of 36C are possible widely across western and southern England, with temperatures climbing to 33C in areas as far north as Yorkshire and 28C in southern Scotland.
Western England and south-east England could then see highs of at least 37C on Friday. The model also shows 36C is possible widely across central England and southern areas.
For Saturday, maps show potential highs of 36C in East Anglia, 33C in Yorkshire, 36C in the south-east, and 33-34C in the Midlands. This hot spell would constitute another official heatwave across the four days.
Counties facing 37C
In total, the GFS model suggests temperatures may reach 37C or more in eight counties next week, all in England: Worcestershire, Warwickshire, Gloucestershire, Buckinghamshire, Berkshire, Hampshire, Surrey, and Sussex.
Met Office outlook
The Met Office says conditions could potentially turn 'very warm or hot' again later this month. However, there is also the potential for some 'thundery interludes'.
The Met Office forecast for August 9 to 18 states: “Further into August, high pressure may become more dominant towards the north or northwest of the UK, with lower pressure to the south or east.
“This means there is a greater chance of frontal systems or thundery interludes to affect southern and eastern areas in comparison to recent weeks, though rainfall amounts could be quite variable with some areas still seeing relatively little.
“For the most part, temperatures look to remain above average, especially in the south, and perhaps turning very warm or hot.”
