As the weather gets warmer and the summer holidays approach, many families naturally head outdoors to cool off. Rivers, lakes, reservoirs and the sea can look inviting, especially during periods of prolonged hot weather, but they can also be extremely dangerous.
Sadly, recent weeks have seen a number of tragic incidents across the UK involving children, teenagers and adults losing their lives in open water. During the May half-term and early summer heatwave, at least 17 people died after getting into difficulty in rivers, lakes and coastal waters, many of them young people. Water safety experts have described the recent deaths as a “public health disaster”.
Unlike swimming pools, open water is unpredictable. Even on very hot days, the water itself can remain surprisingly cold. Entering cold water suddenly can cause cold water shock, leading to involuntary gasping, panic and difficulty breathing. This can affect even strong swimmers.
Other hidden dangers include:
Data from the Water Incident Database shows that 57% of accidental drowning fatalities occur in inland waters such as rivers, lakes and reservoirs, making them the most common locations for these tragedies. In 2025, there were 202 accidental drowning deaths in the UK, with the highest numbers occurring during the summer months.
Teenagers are particularly at risk, and recent figures show drowning deaths among 13-17-year-olds have increased significantly in recent years.
Simple conversations can make a real difference. Encourage your child to:
The Royal Life Saving Society UK and RNLI promote the Float to Live message:
Remember:
Phone β Float β Throw
Never enter the water yourself, as many people lose their lives attempting rescues.
Many people instinctively jump into the water to rescue a beloved pet, but this can put both the owner and the animal at serious risk. Tragically, there have been several incidents where people have lost their lives after entering open water to save their dogs.
Dogs are usually strong swimmers and often manage to make their way back to shore unaided. If your dog gets into difficulty:
Remember: You are far more difficult to rescue than your pet. Keeping yourself safe gives you the best chance of helping your dog once they are back on land.
The RNLI’s advice is simple:
“If your dog goes into the water, don’t go in after them.”

As we head into periods of warmer weather and the summer holidays, we encourage all parents and carers to take a few minutes to discuss water safety with their children. Rivers, lakes, reservoirs and the sea may look calm and inviting, but conditions can change quickly and unexpectedly.
A simple conversation today could prevent a tragedy tomorrow. πππ
