An 18-year-old university student tragically died after suffering cold water shock during a spontaneous night-time swim with friends off a Plymouth beach, a coroner has concluded.
A Fatal Dip in Rough Seas
The inquest at Exeter Coroner's Court heard that Michael Oppong-Yeboah, an environmental science student at the University of Plymouth, entered the water at East Hoe beach with around ten friends from a jiu jitsu society in March 2024. The group had decided on the impromptu evening dip, but conditions in the sea were described as 'rough'.
Michael swam a short distance before beginning to tread water. He was then heard shouting for help after being struck by a large wave, after which he vanished from his friends' sight. Assistant coroner Ian Arrow stated the teenager succumbed to cold water shock, a physiological reaction which severely impairs a person's ability to swim and stay afloat.
A Body Recovered and a Family's Heartbreak
Following an extensive search, Michael's body was recovered from the water at Devonport naval dockyard three weeks later. In a poignant tribute, his mother, Doris Kyeremaa, described her son as a 'very respectful, kind-hearted, humble, peaceful and God-fearing individual'.
She highlighted his love for others, his infectious smile, and his passion for swimming, which had led him to work as a lifeguard at Watford Leisure Centre. Michael was also a dedicated volunteer at the Watford food bank and was highly spoken of by staff during his work experience.
A Coroner's Stark Warning to the Public
Concluding the inquest, Assistant Coroner Ian Arrow issued a clear public safety warning. He expressed hope that 'the publicity surrounding the circumstances of his death makes members of the public aware of the very great danger of entering cold and rough seas particularly at night'.
The tragic case underscores the hidden risks of cold water immersion, even for confident swimmers like Michael. The sudden drop in skin temperature can trigger an involuntary gasp reflex and hyperventilation, leading to panic and rapid incapacitation.
