How to Stay Safe Swimming Outdoors – and Still Have Fun

How to stay safe swimming outdoors – As summer heat intensifies, the allure of outdoor swimming grows, offering a refreshing escape with the promise of free recreation. Yet, this popular activity carries hidden dangers that can lead to serious consequences. In the recent surge of warm weather, at least 18 individuals lost their lives after encountering difficulties in open water, many of them teenagers. The National Water Safety Forum reports that 202 people died in accidental water incidents across the UK in 2025, highlighting the importance of vigilance and preparation.

Expert Recommendations for Open Water Safety

Water safety professionals emphasize that the most effective way to minimize risk is by selecting a location with supervision. BBC News consulted experts who consistently highlighted the value of lifeguarded areas as the safest options for swimmers. A comprehensive list of such beaches can be found on the RNLI website, which serves as a vital resource for those seeking secure environments.

Steve Hall, a volunteer with the Hornsea Rescue charity in East Yorkshire, has witnessed firsthand the dangers of unmonitored swimming. Over nine years, he has responded to numerous emergencies, often finding that preventable risks could have been avoided with basic precautions. Hall, who is a skilled swimmer himself, advises that even strong swimmers should prioritize lifeguarded spots or designated wild swimming areas over rivers and reservoirs.

“It’s really difficult to know what’s going on beneath the surface,” says Becky Hickman, CEO of the Royal Society for the Prevention of Accidents. “You could encounter fast-moving currents, sharp rocks, or debris that pose unexpected threats.”

According to Hickman, many inland water bodies, such as reservoirs and canals, are not as safe as they appear. These locations might hide sudden drop-offs, heavy machinery, or unpredictable currents that can quickly turn a casual swim into a life-threatening situation. Even on calm days, swimmers should remain cautious, as conditions can change rapidly.

Recognizing and Avoiding Rip Currents

Rip currents, often referred to as “underwater rivers,” are a common hazard in coastal areas. Steve Hall explains that these powerful flows can carry swimmers far from shore, even in seemingly safe waters. “A rip current doesn’t need to take you very far,” he notes. “It just needs to pull you out of your depth.” He recounts rescuing families who were only 30 yards from the beach but were unable to return after being caught in a current.

The RNLI highlights that rip currents can be challenging to detect, often indicated by churning, choppy water near the surface. To prepare for such scenarios, Hall recommends that families watch educational videos to learn how to identify these currents. He also suggests practicing the correct escape technique: swimming parallel to the shore until free from the current’s grip, rather than fighting against it directly.

Preparing for Cold Water Shock

Another critical factor in outdoor swimming safety is the temperature of the water. Hickman points out that many UK bodies of water remain below 15°C (59°F) throughout the year, making them “dangerously cold” for those unaccustomed to such conditions. Cold water shock occurs when a person enters the water too quickly, causing a sudden loss of motor control and breathing difficulties.

“Getting into cold water too rapidly can be life-threatening,” Hickman explains. “It’s essential to acclimatize your body before diving in.” Dave Oakley-Jenner, a member of the North Cumbria Search and Rescue team, advocates for a gradual entry. His personal mantra, “ankles, hips and nips,” ensures he slowly lowers each part of his body into the water, allowing his body to adjust to the temperature before fully submerging.

Swimming in natural bodies of water differs significantly from pool environments, according to Sarah Pennicard of the RNLI’s water safety team. The sea, lakes, and rivers present cold, fast-moving, and unpredictable conditions that require extra attention. Pennicard urges swimmers to practice floating techniques in pools to build confidence and skills that can be crucial in emergencies.

Essential Safety Practices for All Swimmers

Before entering the water, swimmers should assess their own abilities and physical readiness. Oakley-Jenner warns against entering water after consuming alcohol, taking drugs, or having a heavy meal, as these factors can impair judgment and coordination. He also stresses the importance of having a phone accessible for emergencies, ensuring that swimmers can call for help if needed.

“Never go swimming alone,” Oakley-Jenner advises. “Having someone on the shore to monitor your group can make all the difference.” Steve Hall adds that this person should be familiar with the location, able to identify potential hazards, and capable of alerting authorities if a swimmer is in trouble. “Inflatables are not for the seaside,” Hall notes. “They’re for pools, but they can be lifesavers in open water if used correctly.”

Wind changes can create unexpected challenges, pulling swimmers out to sea quickly. If this happens and a swimmer feels unsure about returning, they should stay on the inflatable to make themselves more visible. Rescue teams can spot inflatables more easily than a person’s head, which might be harder to locate in vast open waters.

While the thrill of outdoor swimming is undeniable, the combination of natural hazards and human error makes preparation essential. By following expert guidance, swimmers can enjoy the freedom of open water without compromising their safety. Whether it’s choosing a supervised location, recognizing rip currents, or acclimatizing to cold temperatures, each step contributes to a more secure experience. The key is to stay informed, stay alert, and prioritize caution over carefree adventure.
