Forecasters have said the UK could see its hottest day of the year today, with temperatures set to reach 37C in London and the South East.
It is the second day of a heatwave that is expected to last until Sunday and potentially into the most part of next week.
The threshold for a heatwave is three days of temperatures over 25C (77F) across most of the nation and 28C (82.4F) in London.
John Hammond from Weather Trending told talkRADIO the heat is set to “hang around for some time”.
Speaking with Julia Hartley-Brewer, he said: “The atmosphere is stuck, whereas last time we had a quick surge up from Spain then a cold front came in from the Atlantic and we were back to normal, that’s not the case this time.
“The atmosphere is set up that we’re just going to get this warm wind wafting up from France and Spain and just sitting over us for the best chunk of a week.”
The Met Office has warned that after a slightly cooler week people could underestimate the heat, which could cause dehydration and sunburn, especially among the most vulnerable.
And Public Health England (PHE) has issued a heat-health warning, with people advised to stay cool indoors by closing curtains that face the sun and ensuring pets or children are not kept in vehicles.
