Oxfordshire Fire and Rescue Service has warned that warm weather increases the risk of people getting into difficulty in open water across the county.

Reservoirs, lakes, and rivers may look inviting in warm weather, but these hidden dangers can injure or kill.

The service is reminding the public that even on the hottest days, open water can remain dangerously cold and lead to a ‘cold shock’ response if someone falls or jumps in unexpectedly.

It comes after the county has experienced water-related tragedies in recent years including 20-year-old student Noah Moss, who accidentally fell into the River Thames and hit his head, drowning by King’s Lock in Wolvercote.

John Keith Jones also drowned in the river near Osney Lock in April 2023 and Wesley Akum-Ojong, a 19-year-old Oxford University student, drowned in the River Thames on June 21, 2024, while celebrating the end of his exams in Port Meadow.

Deb Forder, safety manager for Oxfordshire County Council’s Fire and Rescue Service, said: “Open water can look appealing, especially on warm days, but it is also very dangerous.

“That is why the practical advice we’re offering is so important, particularly during the hot weather when residents are more likely to be tempted to take a dip.”

Hidden hazards beneath the surface, including rocks, debris, or strong currents, can also pose serious risks.

Ms Forder said: “Please consider things such as letting friends and family know your route near water and what time you should return.

“Carry a whistle and your phone in a water proof pouch to draw attention if you do get into difficulties.”

She explained that sudden immersion in cold water can trigger an involuntary gasp, causing people to inhale water and potentially leading to hyperventilation.

This reaction can result in disorientation.

Ms Forder said: “If you fall in, remember to relax, lean back and ‘float to live’ until you can control your breathing.”

Anyone who sees someone in trouble in the water is urged to call 999 or 112 immediately.

They should not attempt to enter the water themselves but instead try to throw something that will float to the person in distress.

The fire service has also advised the public to be aware of dangers such as strong currents, underwater hazards, and low water temperatures, which can all be life-threatening.

The fire service also advises choosing a lifeguarded beach if planning to go into the sea.

Ms Forder said: “A simple change to our behaviour can reduce the risk of drowning.

“Avoid high risk areas, be aware of your surroundings and know how to react if you or someone else falls in.

“Respect the water, even if you’re a good swimmer and familiar with the river, lake or reservoir. Be water aware.”
