The UK has seen its warmest start to May on record as temperatures soared to over 29C in the spring sunshine.
The Met Office said 29.3C (84.7F) had been recorded at Kew Gardens in southwest London, passing the previous 1 May record of 27.4C (81.3F) set in Lossiemouth in 1990.
Thursday was also the warmest day of the year so far, beating the previous high of 26.7C (80F) reached in Wisley, Surrey, on Wednesday.
But the heat is not expected to last for the bank holiday weekend, with cooler weather starting to drift in from the north on Friday.
Temperatures are expected to ease by Friday and Saturday, meaning cooler conditions of 14C to 18C across the UK.
Stephen Dixon, a Met Office spokesman, said: “Temperatures tomorrow will be slightly reduced from what we’ve seen today, possibly 26 or 27 degrees in the far southeast of England through the day tomorrow.”

What has led to the hot spell?
Forecasters said the hot spell has been due to the jet stream remaining stuck north of the country, allowing high pressure to settle.
Last month was also the sunniest April in the UK since records began in 1910, with 47% more sunshine hours than the long-term meteorological average, and the third warmest April on record, according to provisional Met Office figures.
Rainfall was well below average for most of the UK last month, with just 56% of expected totals recorded.
And Tyne and Wear had its second driest April on record, with only 7% of its usual rainfall.
Scientists see fingerprints of climate change all over tumbling records
Britain has basked in the early taste of summer.
The warmest May Day, the third warmest April and a spring that has so far beaten temperature records dating back to 1884.
But this is more than just natural variation.
Scientists see the fingerprints of climate change all over the tumbling records.
Maps released by data analysts Climate Central show that across large parts of the country, human-induced climate change has made the high temperatures four or even five times more likely.
The warm – and dry – weather this spring has led to a steep rise in wildfires.
Figures from Europe’s satellite monitoring service Copernicus show that more than twice as much land has been burned so far this year in the UK as the average for a whole year.
Latest data shows 29,484 hectares (72,857 acres) have been scorched in 2025, compared to a yearly average of 12,613 hectares (31,167 acres) between 2012 and 2024.
Temperatures will fall sharply into the Bank Holiday weekend.
But the fire risk remains ‘very high to extreme’ across much of Scotland and ‘very high’ for large parts of England.
The warmth that brings joy to many of us also brings jeopardy.
Chief Inspector David Mather, of Nottinghamshire Police, said: “I would like to take this opportunity to highlight this case as a reminder of the devastating consequences of entering open water – regardless of whether people do so deliberately or inadvertently.”

The London Fire Brigade said its crews responded to 565 water-related incidents last year and have already attended around 160 in the first quarter of this year, with incidents ranging from rescuing people to animals stranded on lakes and ponds.
‘Water temperatures can be dangerously cold’
Assistant commissioner for prevention and protection Craig Carter said. “Even when the sun is shining, water temperatures can be dangerously cold. Cold water shock can affect anyone, no matter how fit or experienced they are. It can lead to water inhalation, and, in the worst cases, drowning.”

The Royal National Lifeboat Institution (RNLI) offered similar warnings, advising those planning to swim at a lifeguarded beach to swim between the red and yellow flags.
Fire services warned that the warm weather means there is a “heightened” risk of grass and wildfires which can spread more easily during the dry spell, as firefighters have been battling what they described as a large wildfire in the Peak District.
The RAC also cautioned drivers on the roads, with spokesman Rod Dennis saying breakdowns are expected to “soar”, while the NHS reported searches for hay fever advice had doubled from Monday to Wednesday.
A man has been arrested on suspicion of murder after three children and a woman died in a house fire in Brent, northwest London.
Metropolitan Police officers are investigating after being called to assist firefighters in Stonebridge, near Wembley, shortly after 1.20am.
A 43-year-old woman and three children, a 15-year-old girl, an eight-year-old boy and a four-year-old boy, died at the scene, the force said. Their next of kin have been informed.
Police are waiting for an update on the conditions of two others who were taken to hospital.
A 41-year-old man was arrested at the scene in connection with the incident and remains in custody.

Eight fire engines and around 60 firefighters responded to the blaze, the London Fire Brigade (LFB) said.
Two terrace houses, each with three floors, were severely damaged in the fire, which was under control by around 3.25am, the fire service added.
Firefighters rescued the woman and one of the children from the second floor of the house, but they were declared dead by air ambulance crews.
The two other children were found inside the property and were also declared dead at the scene, LFB said.

LFB assistant commissioner Keeley Foster said: “Upon arrival, firefighters were met with a well-developed fire, involving two adjoining properties. Crews immediately set to work carrying out firefighting operations in order to bring the incident under control.
“Sadly, a woman and three children have died as a result of this fire.
“Crews wearing breathing apparatus were able to rescue the woman and one of the children from the second floor, but they were later declared deceased at the scene.
“A further two children were discovered to have died in the fire, as crews carried out a search of the properties involved.”
She added: “This is an extremely tragic incident, and the thoughts of everyone across the brigade are with those impacted by this incident.”

London Ambulance Service said an air ambulance, incident response officers, advanced paramedic and hazardous area response team were deployed to the scene.
Superintendent Steve Allen, from the Met’s local policing team in northwest London, said: “This is an extremely tragic incident and our thoughts are with everyone involved.
“Officers arrested a man at the scene and we continue to work alongside investigators from the London Fire Brigade to establish the cause of the fire.
“Emergency services will remain in Tillett Close throughout the day as these enquiries take place.”
Mayor of London Sadiq Khan said in a post on X: “This is devastating news and my thoughts are with the family, friends and wider community of the four people who sadly have lost their lives.
“I remain in close contact with the London Fire Brigade and Metropolitan Police as they work to establish the cause of the fire and offer support to all those impacted.”
Dawn Butler, the local Labour MP for Brent East, posted: “Devastated to see the fatal fire at homes in Tillett Close last night.
“My prayers are with the family and friends affected by this is a very sad tragedy.
“@LFB_Brent worked hard to get it under control, thank you.”
The teacher of one of the Southport stabbing victims has told Sky News they “don’t want her to be forgotten”, 10 months after the knife attack in which she was murdered.
Seven-year-old Elsie Dot Stancombe was killed along with Bebe King, six, and nine-year-old Alice da Silva Aguiar in an attack by Axel Rudakubana at a Taylor Swift-themed dance class last July.
Jennifer Sephton, headteacher of Farnborough Road Infant School, will be skydiving to raise funds for the Elsie’s Story charitable trust, which has been set up in memory of the former pupil.

“She’d been with us for four years, throughout her education,” Ms Sephton told Sky News, “and we just want everybody to know Elsie’s spirit.”
Describing Elsie as “such a determined young lady,” Ms Sephton said Elsie had “a real zest for life, and a sparkle in her eye all the time.”
She added that Elsie’s Story, which has been set up by Elsie’s family, is about “continuing that legacy.”

In the aftermath of the July 2024 attack, the gates outside Elsie’s school were lined with flowers, balloons, and cards bearing her name.
Since then, memorial benches and a tree have been planted in the school grounds, providing pupils and staff with a place to “remember and reflect”, Ms Sefton says.
“[Elsie’s death] had such an impact on all our community,” the teacher said, “it’s had an impact on her friends, their siblings, our school as a community and our staff.”
Ms Sephton will be joined in the skydive by Adrian Antell, headteacher at the adjoining junior school where Elsie had been due to start.
“Elsie was due to come to us last September,” he told Sky News, “but what we’ve learned about her is that she had a wonderful impact in the infant school, and we don’t want her to be forgotten.
“We want her name to have to live on and to be thought of in a positive way.”
Mr Antell said they continue to support Elsie’s classmates, who joined the new school without her.
“There’s no instruction manual for this,” he explained, “every day is different, and every day is one step at a time.
“So all we can do as a school is to think about individual children and support them in the best way we can.”
Scientists from Kew Gardens are using a new study to track which trees bees prefer to try to stem the decline in our vital pollinators.
Bee populations are falling all over the world due to a mixture of habitat loss, climate change, and the use of pesticides, with a devastating impact on our biodiversity and food production.
But it’s feared that not enough comprehensive, global research is being done to understand the issue or find solutions.

UK becoming a no-fly zone
Researchers based at Wakehurst in Sussex, known as Kew’s “Wild Botanic Garden”, have begun placing advanced bio-acoustics sensors in some of their trees to track which ones bees favour.
They hope it’ll help urban planners know which trees to plant in built-up areas, as a way of combating the worrying decline in bee numbers.
Pollination research lead Dr Janine Griffiths-Lee said: “Nearly 90% of our flowering plants depend on the contribution of pollinators, but in the UK the population of flying insects in the last 20 years has decreased by around 60%.
“It’s really hard to be able to put a figure on the decline of our pollinators, but we do know that globally the number is declining.
“And with that comes crop yield instability and the loss of an essential ecosystem service.”
Their new, non-invasive monitors listen for the buzz created by bees’ wing beats, building up heat maps of the most popular spots.

‘We’re facing twin crises’
Dr Griffiths-Lee said: “If you think about the tree’s footprint, it’s very small, but they’re huge 3D structures covered in pollen and nectar, which are essential resources of pollinators.
“So we really wanted to think about which are the best trees for bees for us to plant, and that can inform landscape planners, urban architects.”
Eight different species of tree were chosen for the study, including horse chestnut and lime trees, with a mixture of native and non-native species.
The scientists have also been gathering DNA from pollen, which also helps them to map which plants and flowers the insects prefer.
Wakehurst’s director, Susan Raikes, calls the 535-acre estate a “living laboratory”, and said the project’s all about searching for nature-based solutions to the impacts of climate change.
“The stakes couldn’t be higher, really. We know that we’re facing these twin crises of biodiversity loss and climate change,” she added.
“We need to be able to understand, as the climate changes, which plants from warmer climes will be good here in the UK for pollinators in the future.
“If all of our native plants are struggling, then we need to find new sources of pollen – for us all to survive.”
