Weather maps indicate the UK could experience a heatwave starting Sunday, with temperatures soaring to 37C by next week. Netweather data shows temperatures climbing above 30C for six consecutive days.
Sunday and Monday highs
On Sunday, highs of 34C are possible, with much of the south reaching 32C or higher. The East and West Midlands could see around 32C, while Suffolk may reach 32C. Northern England will also be warm, with Greater Manchester possibly hitting 29C.
Monday is set to be hotter, with possible highs of 37C in Berkshire, nearing the record 37.7C recorded at Lingwood, Norfolk on June 26. London, Cambridgeshire, and parts of the south west could reach 35C, while Hertfordshire and Suffolk may hit 36C.
Midweek and beyond
Tuesday's maps suggest much of the UK will face more heat, with the warmth extending further north. The Midlands and south will remain in the mid-30s, with Greater Manchester and Cheshire reaching 34C and 35C respectively.
Wednesday could see parts of Yorkshire reaching 30C, while Wales and Scotland, although cooler, may climb to the mid to high-20s. Thursday brings highs of 35C in London and surrounding areas, with much of the region at 34C. Friday could also see 35C in Sussex and Norfolk.
Heatwave definition
The Met Office defines a heatwave as "an extended period of hot weather relative to the expected conditions of the area at that time of year, which may be accompanied by high humidity." The UK threshold is met when a region records at least three consecutive days with daily maximum temperatures meeting or exceeding the heatwave temperature threshold, which varies by county from 25C to 28C.
This data suggests a heatwave is likely next week, as warmth will cover much of England for six days. The Met Office forecast says it will be dry for most on Monday, with temperatures on the very warm to hot side. The long-range forecast adds: "For the most part, temperatures look to remain above average, especially in the south, and perhaps turning very warm or hot."
