Parts of the UK are officially in a heatwave as temperatures soared to within reach of May records.
The first area of the UK to hit the threshold was Santon Downham in Suffolk, which reached the criteria of recording temperatures of more than 27C for three consecutive days at 11.30am on Sunday.
The other areas now officially in heatwave conditions are: Heathrow, Kew Gardens and Northolt, all in London; Benson in Oxfordshire; Brooms Barn in Suffolk; and High Beach and Writtle, both in Essex.
Temperatures could rise again, with highs of 31C predicted in the south-east, and further on Monday, when peaks of between 33C and 34C are possible.
The climate crisis is increasing the likelihood of extreme heat. Large parts of western Europe are experiencing similar peaks, with Météo-France, the French national weather forecaster, warning periods of exceptional heat are expected to come “more and more often and more and more prematurely, and to be more and more intense”.
A Met Office spokesperson said: “Breaking the 32.8C May record is around three times more likely now in our current climate than it would have been in natural climate conditions before the Industrial Revolution. “What was around a one-in-100-year event is now around a one-in-33-year event.”
The Met Office meteorologist Jonathan Vautrey said there would be “plentiful amounts of sunshine” in many parts of the UK on Sunday, bringing temperatures upwards of 30C.
“If we hit that 33C, maybe even locally close towards 34C, that would bring us our hottest bank holiday day on record, as well as our hottest day in May on record,” Vautrey said. “So it really is quite exceptional heat that is building for the time of year.”
The criteria for a heatwave are set by the Met Office. One is declared when temperatures reach or exceed 28C in London and its surrounding counties on at least three consecutive days.
For many other areas of England, as well as south-east Wales, it is 26C or 27C. The threshold is 25C for Scotland, Northern Ireland, much of Wales and northern England.
Saturday was the UK’s first 30C day of the year, with 23 May being the earliest date 30C was reached since 1952.
Sunbathers flocked to beaches across the UK. Pictures from Margate, Weymouth and Folkestone showed packed-out sands full of beachgoers soaking up the sun.
Given the hot weather, the cricket ground Lord’s has relaxed its strict dress code in its pavilion. The Marylebone Cricket Club usually requires spectators in the pavilion to wear lounge suits or tailored jackets and ties, but that has been eased.
There were drinks breaks at the League One playoff final between Bolton Wanderers and Stockport County at Wembley on Sunday and there are likely to be more refreshment breaks in the Premier League games as the top flight season concludes.
People living in three villages in Kent experienced no water or low water pressure for a second day on Sunday. The affected areas are Charing, Challock and Molash near Ashford, where people first reported water supply problems on Saturday evening.
South East Water apologised and said the issue was resolved overnight, but added that water supply problems resumed at about 09:25 BST on Sunday due to “issues with the pumping station”.
The UK Health Security Agency (UKHSA) issued amber heat health alerts on Friday morning for the East Midlands, the West Midlands, the east of England, London and the south-east.
The alerts will remain in place until 5pm on Wednesday. They mean there is likely to be a rise in deaths, particularly among those aged 65 and over or with health conditions and an increased demand on all health and social care services, according to the UKHSA website.
While most of the UK was bathed in sunshine, north-west Scotland faced scattered cloud and patches of rain, according to the Met Office.
