Water safety experts have issued urgent warnings following the deaths of nine people in open water incidents across the UK during the recent heatwave. Seven children and two adults, including a grandfather in Cornwall, lost their lives in rivers, lakes, reservoirs, and the sea as temperatures soared to 35°C.
Tragic Losses Across the Country
Junior Slater, 12, was the latest victim identified after his body was recovered from the River Ribble in Lancashire on Tuesday. His family paid tribute: "Our little blue-eyed boy. He will be truly missed. He was the life and soul of our lives." Locals said children often ignore warning signs along the riverbank, which state: "People have drowned here swimming and wading. For your safety don't let it be you."
Other victims include 13-year-old Reco Puttock, who died after being pulled from a reservoir in Halifax; Lillianna Tomlinson, whose body was found at Kingsbury Water Park in Staffordshire; and 15-year-old Declan Sawyer, discovered in a Lincoln lake. A 17-year-old boy also died at Pickmere Lake in Cheshire, and a teenage boy was recovered from Hawley Lake in Hampshire.
Heroic Grandfather Dies Trying to Save Granddaughter
Phil Crow, 68, tragically died after entering the water at Tregirls Beach near Padstow, Cornwall, while attempting to rescue his nine-year-old granddaughter, Sia Briskham, who got into difficulty due to a sudden change in tide. A 72-year-old woman also died after being pulled from the sea at West Angle Bay beach in Pembrokeshire.
Cold Shock Response: A Hidden Danger
Professor Mike Tipton, chair of the National Water Safety Forum, explained that while air temperatures rise quickly, water temperatures remain at winter levels, around 13°C. This leads to "cold shock response," causing a gasp and uncontrollable hyperventilation, often a precursor to drowning. "About 60% of those that die going into cold water do so in the first minute or so of immersion," he said.
Calls for Water Safety Education
Kate Rew, founder of the Outdoor Swimming Society, emphasized the need for swimming lessons and water safety education, particularly for disadvantaged children. "In the most deprived parts of England, fewer than half of children can swim 25 metres by the end of primary school," she noted. She urged targeted campaigns on social media platforms like TikTok and Instagram to reach young people.
The Royal Life Saving Society (RLSS UK) called for immediate inclusion of water safety in school curricula, warning that waiting until September could lead to further tragedies. "While a foundation of water safety will be included in England's school curriculum from September, this vital information needs to be taught now across the UK to prevent tragedies," the charity stated.
Authorities continue to urge caution, reminding the public to be aware of the dangers of open water, especially during hot weather.
