UK Weather: Britain Experiences Record-Breaking Bank Holiday Temperatures
Senior meteorologist Greg Dewhurst said: “We reached 28.6C at about 11am and it was 28.9C a short time later.
“But we will see changes as we go through the week, with the chance of some thunder and showers across the country from Tuesday.
“The south east of England will hold on to the sun for an extra day, and we could see temperatures in the low 30s.”
Temperatures hit an August Bank Holiday high of 33.3C (92F) at Heathrow on Sunday, while hundreds of thousands of people enjoyed what is thought to be the hottest Notting Hill Carnival ever in west London.
The previous best late August Bank Holiday temperatures before this weekend were 31.5C (88.7F) at Heathrow in 2001, 27.3C in Velindre, Powys, in Wales and 27C (80.6F) in Knockareven, Co Fermanagh, both in 2003, plus the 26.7C (80.06F) that was recorded in Aviemore, Inverness-shire, in Scotland in 1984.
Wales enjoyed a record 28.6C in Hawarden on Sunday when the top temperature in Northern Ireland was 24.2C at Stormont Castle.
Scotland’s top temperature was the 28.4C recorded at Bishopton near Glasgow on Sunday.
