Brits are being warned to take care in and around open water after at least nine people died in incidents in the sea and in lakes during the Bank Holiday heatwave.

Seven teenagers, a grandfather in his 60s and a woman in her 70s are known to have died - including two teenagers pulled from the water today.

People have taken to local lakes and ponds in a bid to keep cool amid record-breaking temperatures, including the hottest ever daytime record of 35.1C that was set yesterday.

But the Royal Life Saving Society has warned Britons to take extra care following a spate of water-related deaths, noting that 'warmer weather unfortunately sees an increase in accidental drownings'. 

And the emergency services are struggling to cope with increased demand - with London's ambulance service reporting its busiest day since the pandemic.

Cheshire Police found a body in Pickmere Lake near Warrington earlier on Wednesday as they searched for a 17-year-old boy; Hampshire and Isle of Wight Constabulary said it had also recovered a body at Hawley Lake in Blackwater.

On Bank Holiday Monday, 13-year-old Reco Puttock was pronounced dead after being found in Leadbeater Dam in Halifax, West Yorkshire; the body of a 16-year-old girl was found at Warwickshire's Kingsbury Water Park; and another boy was found at Rother Valley County Park in Rotherham.

Fifteen-year-old Declan Sawyer died after getting into difficulty at Swanholme Lakes in Lincoln on Sunday; police in Lancashire have recovered 12-year-old Junior Slater's body after he got into difficulty swimming in the River Ribble on Tuesday.

And heroic grandfather Phil Crow, 68, suffered a cardiac arrest as he ran out to the sea trying to rescue his wife and granddaughter after they got into difficulty at Tregirls Beach in Padstow, Cornwall on Monday.

The BBC reported that the body of a 72-year-old woman was recovered from the water at West Angle Bay beach in Pembrokeshire, Wales on Sunday. 

Experts say that if people do want to swim they should do so somewhere supervised by lifeguards. They also discourage jumping from heights, and for people to assess their ability to swim before entering the water.

Entering any water colder than 15C can cause the body to enter cold-water shock, when the blood vessels in the skin close in response to the cold, forcing the heart to work harder.

It can lead to panic, hyperventilation and decreased dexterity - putting sufferers at risk of drowning. Average UK and Ireland sea temperatures are just 12C, according to the RNLI, but inland waters can be much colder.

Paul McCourt, assistant commissioner for the London Fire Brigade, warned: 'We know that the warmer weather can tempt people to cool off in rivers, reservoirs and lakes, but even in hot weather most inland water in London remains very cold, and can be below 16C. 

'If you are planning to swim outdoors, only do so in designated areas, and ensure that lifeguards and safety equipment are present.'

Anyone who does get into trouble is advised to 'float to live' - lying on their back and relaxing to catch their breath if they do struggle when they enter cold water. 

The London Ambulance Service said it received 1,821 calls on Tuesday amid scorching temperatures, up more than a third compared to a week prior. 

It is operating at REAP 4 - a DEFCON-style scale that suggests 'extreme pressure' on paramedic services.

Alison Blakely, deputy chief paramedic, said: 'We want people to enjoy the weather but please take steps to look after yourselves and others around you.'

The advice comes as Brits continue to flock to beaches and swimming spots amid the heatwave - with tragic consequences.

Junior Slater has been named as the 12-year-old boy who drowned after swimming in the River Ribble in Lancashire.

Junior is believed to have jumped from a 15ft concrete jetty into the river at Ribchester when he got into difficulty and was swept away.

His grandmother Denis Peason posed on Facebook, 'When you wake up hoping it was a dream. Goodnight God Bless our beautiful Grandson Junior Forever 12.'

And his other grandmother, Christine Slater said: 'Can't believe what happened Junior… for ever 12…You're with Grandad now, love and miss you.'

The Year Seven pupil got into difficulty in the River Ribble on Tuesday afternoon as the country baked in a 35C heatwave. Mourners left flowers at the scene.

One friend of the boy placed a touching floral tribute close to where the youngster lost his life. He wrote: 'RIP my bro! Forever miss you. Never forgotten.'

Junior's family spoke of their heartbreak on social media. Formal identification has not yet taken place but Lancashire Police are understood to believe the body is his.

Cousin Luke JG Slater wrote: 'RIP junior. Fly high kidda. Don't be terrorising grandad too much up there gonna miss ya, cuz.'

Family member Jordan Sergeant posted: 'RIP Junior Slater. Never ever did I think I would be writing this about you.

'Words don't describe how we are all feeling down here but ur grandad Batty will look after you now and until me Jake and everybody else see you again it's nothing but love little man shine bright up there.'

Junior is believed to have been jumping from a 15ft concrete jetty into the River Ribble, Ribchester when he got into difficulty and was swept away.

His friends alerted the emergency services on Tuesday afternoon, and a huge search operation was launched.

Police underwater search teams, helicopters and drones were deployed to search the area. His body was found at 7.50pm on Tuesday.

The riverbank is lined with warning signs stating: 'People have drowned here swimming and wading. For your safety don't let it be you.'

Another read: 'Swimming is not advised - cold water shock - fast moving water - hidden currents - hidden dangers.'

Earlier, one resident told BBC North West Tonight that the area was a 'hotspot' for children and it tended to be people from out of the area who visited to swim.

Ann-Marie Ruddock, who has lived in Ribchester since 1991, said: 'Locals are well aware of the dangers of the river and they tend to keep away from it. It's nightmare scenario.'

But locals told the Daily Mail that youngsters ignore the signs - and their warnings - all the time.

One said: 'Kids come in on the bus from places like Ribbleton or Longridge. They jump in from the concrete jetty. It happens every year, we tell them it's dangerous but they don't care.

'I feel so sorry for his family and friends. They must be traumatised. The local children don't go in the river, they know it's dangerous. They've had it drilled into them.'

Lancashire Police said the boy's family was being supported by family liason officers. 

Phil Crow, 68, lost his life as he bravely entered the water at Tregirls Beach, near Padstow, on Bank Holiday Monday in a bid to rescue Sia Briskham after a sudden change in the tide. 

His wife of 50 years Tina, 68, was also pulled out to sea and had to be rescued by a passing boat before being checked by a paramedic. 

Mr Crow suffered a 'cardiac arrest in the sea' while trying to save them, and was later pronounced dead at the scene. Tina and Sia were brought to safety by members of the public.

The retired stonemason was a lifelong Padstow resident and leaves behind 11 brothers and sisters, as well as five grandchildren. 

Tina said: 'We were jumping up with the waves then all of a sudden we couldn't hit the floor when we landed, it was deeper and was pulling us out.

'He was shouting at her to lay on her back but she couldn't stand, he pushed her to safety, but doing so meant he couldn't get back himself. He was pushing her feet and just shouting swim, swim, swim.'

Speaking of the incident in Cornwall, Tina said another of their grandchildren, Nate, 12, was on the beach shouting for help but her husband told him to stay out of the water and get help. Around 15 people joined in the rescue.

She added: 'We have been coming to the same beach for 50 years because it is the safest in the area.

'We just want to thank all the emergency services who were absolutely fabulous, kind and very respectful in a difficult situation. It was difficult for them too because many of them knew him personally.'

Daughter Mel Thomas, 49, added: 'He died a hero and wouldn't have had it any other way. 

'He saved his granddaughter's life, she's safe but her and her brother Nate have been offered counselling.

'He has five grandchildren and adores every one of them, absolutely adored them. He always told them he loved them so much, he would die to protect them and he is a man of his word.'

Phil and Walsall-born Tina met in Shropshire after he moved up there for work with his brother Nigel.

Tragically, Phil's great grandfather William Brabyn died on the same beach in 1847 while rowing a boat that got stuck on the infamous Doom Bar. 

Angie Crow, mother of Nate and Sia, said: 'I'm just so thankful for him and what he did.'

Mr Crow was a popular local figure known for his sense of humour, which saw him dress up as a pirate and a superhero for recent events in the town.

The local Coastguard reported that a team of theirs had been called out to an incident at Tregirls beach and that the Rock RNLI Lifeboat and Cornwall Air Ambulance had also attended.

But they were unable to save Mr Crow, they said, adding: 'Our thoughts are with the family and our local community.'

A spokesperson for Devon and Cornwall Police said: 'We were called by the Ambulance Service at around 3.50pm on Monday 25 May following a report of a man suffering a cardiac arrest in the sea at Tregirls Beach, Padstow.

'Emergency services and the RNLI attended the scene but sadly, the local man in his 60s was pronounced deceased at the scene. His next of kin are aware.

'The death is not being treated as suspicious and a file will be prepared for HM Coroner.'

Elsewhere, a Cheshire Constabulary spokesman said officers were called to reports of a missing 17-year-old boy last seen in the water at Pickmere Lake, near Northwich, at 4.50pm on Tuesday.

Extensive searches were carried out and a body, believed to be the missing teenager, was later recovered from the lake, the spokesman said.

Chief Inspector Jamie Lewis said: 'This was a young boy who had his entire life ahead of him. At what is an incredibly difficult time, our thoughts remain with the boy's family, friends and everyone who knew him.'

He added: 'Over the bank holiday weekend, we have sadly seen the very real dangers of swimming in open water.

'We understand that with the warm weather many people could be tempted to take a dip in open water to cool off, but residents must be aware of the potential deadly consequences.'

Meanwhile, Hampshire Police confirmed that a body had been found in the search for a missing teenager who was last seen swimming in Hawley Lake near Blackwater.

They said formal identification has not taken place, but the family of the teenager have been notified.

Reco Puttock, 13, died in hospital after being pulled from the water at Leadbeater Dam, a popular swimming spot in Halifax, West Yorkshire, at around 3.20pm on Monday.

The teenager was rushed to hospital but sadly died despite the efforts of paramedics.

Just hours later, the body of a girl, believed to be 16, was recovered from a lake at a country park in Warwickshire.

South Yorkshire Police also responded to reports that a teenage boy had gone into the lake at Rother Valley County Park in Rotherham and had not re-emerged. 

Emergency services recovered his body in the early hours of Monday morning. 

And on Sunday, police confirmed that 15-year-old Declan Sawyer drowned at Swanholme Lakes in Lincoln at around 2.30pm. 

A 15-year-old girl is also fighting for her life in hospital after getting into difficulty in the water off Formby Beach, Merseyside.

The parents of Reco, who died after entering the water in Halifax, paid tribute to their son, describing him as close to his three sisters and 'especially with his big sister'.

His mother, Sam Puttock, said: 'He loved being out with his friends. That's what he enjoyed most.

'I don't know what to feel, I think I've just cried and cried since about 7am this morning… I don't think I can bring myself to any more at the minute.'

Declan Sawyer's father, Carl, warned other parents to educate their children on the dangers relating to bodies of water while issuing a touching tribute to his son.

Carl described the 15-year-old as 'very much loved by his friends and family', adding he will be 'missed dearly by many'.

'With his tragic and unexpected passing on Sunday at Swanholme Lakes, we would like to raise awareness about children playing near any rivers or lakes in the hot weather,' he said.

'Please can all parents, friends and family make their children aware of the dangers surrounding water.'

In Warwickshire, the 16-year-old girl's body was recovered by specialist police teams at around 7.20pm on Monday. 

Her father was 'frantically' seen searching the riverbank by onlookers, who said he entered the body of water in a bid to find his child.

Floral tributes were laid at the scene for the victim, named only as Lil.

Speaking at the scene, Chief Inspector Ben Hembry, North Warwickshire Area Commander, said: 'We were called at around 6pm to reports of youths in the water.

'One was in particular difficulty. When we arrived it was identified a female teenager had gone missing underwater.

'A multi-agency response of police, ambulance and fire all attended as well as a range of support from the park to do an extensive search.

'I believe she was a local girl and this is an area frequented by young people in hot weather.

'We are desperate to get the message across for people to stay out of open bodies of water.'

When asked about youths jumping off the bridge, he added: 'Across open water where there is the opportunity for young people to do this these practices do take place.

'And I believe that is part of what took place here on Monday.'

A family member at the scene said: 'We don't know exactly what happened yet.

'There was some people seen jumping off the bridge but she wasn't.

'There was a young boy her age who jumped in to try and save her at the time. He's the unsung hero, please let the police just do their job as speculation doesn't help.

'She wasn't able to swim so she was never going to jump off a bridge into the water.

'All an officer told me is that 'I know it's of limited comfort but she didn't suffer, it was instant' so there has been an incident.'

In a separate incident, outside the UK, 15-year-old Abbie Carmody-Pepper vanished at Burrow Beach in Howth, Dublin, after entering the water with friends.

Her body was pulled out on Sunday evening following an extensive search operation.

Abbie's friend Aoife has since organised a GoFundMe page to raise funds to support her family with funeral costs.

Separately, concern has been raised after a man went missing near a lake in South Wales.

Stephen Faulkner, 66, was last seen walking near the water at Glyncornel Lake in Tonypandy, South Wales as temperatures soared.

His family raised the alarm after he had not been seen since Sunday - and are appealing for help to find him.

Police said helicopters, drones and specialist CSI dogs have been carrying out searches at the beauty spot.

Mr Faulkner is described as having a stocky build with tattoos on both arms.

He was wearing blue jeans, a blue t-shirt with a black gilet and brown trainers at the time he went missing.

Experts have warned about the dangers of some swimming spots, which become popular during hot weather. 

Lifeguard rescues more than doubled last year, according to the Royal National Lifeboat Institution (RNLI).

Ashley Jones, Head of Water Safety & Education at Royal Life Saving Society UK (RLSS UK), said: 'We're urging the public to choose lifeguarded locations wherever possible, where safety measures and supervision are in place.

'If you are spending time near water with children, always supervise them closely, keep them within arm's reach, and consider dressing them in brightly coloured swimwear to improve visibility.

'Open water environments are very different from controlled swimming areas. There may be hidden hazards beneath the surface, strong currents, and colder temperatures that can seriously affect your ability to swim. It's vital to respect your limits, avoid swimming alone, and talk to your family about water safety before you visit.

'If you see someone in trouble, don't be tempted to enter the water to rescue them. Instead, call 999, encourage them to float on their back, and throw something that floats to assist them. Taking simple precautions can help prevent tragedies and ensure everyone stays safe while enjoying the water during warmer weather.'

Elsewhere, Warwickshire Fire and Rescue Service warned people about the dangers of entering open water as the weather continues to warm up.

'The weather is warming up and you might be tempted to cool off in water, but danger could be lurking under the surface,' they said.

'Even on warm days, the water can still be very cold and cold water shock is highly dangerous.

'We experience an increase in call-outs to water-related incidents in the summer months. Please help us to keep you safe and avoid entering bodies of water.'
