The UK basked in another scorcher of a day on Sunday, the joint hottest of the year so far.
The mercury rose to 32.2C in Coningsby, Lincolnshire, matching this year’s record set on June 10 in Chertsey, Surrey.
Coningsby is where the UK’s hottest ever temperature of 40.3C was recorded on July 19 last year.
The Met Office warned sun-lovers to enjoy the heat responsibly as a teenage girl died after being pulled from the sea and a grass fire was sparked in London.
The 15-year-old girl and a boy were airlifted to hospital off Cleethorpes beach in Lincolnshire on Saturday evening.
Humberside Police said: “We can confirm that a girl, aged 15, has sadly passed away following a multi-agency search to locate two missing children off the coast of Cleethorpes, North East Lincolnshire.”
The boy has since been discharged from hospital after receiving medical care.
Meanwhile, the London Fire Brigade said 10 fire engines and around 70 firefighters have been dispatched to tackle a grass blaze on Rammey Marsh in Enfield in the north of the city.
Around two hectares of grassland were alight on Sunday afternoon.

Met Office meteorologist Amy Bokota said: “Stay hydrated and make sure you are wearing sun protection as we have high UV levels.
“Make sure you drink lots of fluid and stay out of the sun.
“Make sure you are not putting any disposable barbecues on any grassland area.”
