Record-breaking temperatures in May brought tragedy across the UK, with a series of drowning incidents leaving families and communities devastated. From a grandfather who died rescuing his granddaughter to a teenager retrieving a ball from the sea, the hot weather brought heartbreak nationwide.
A total of 19 people lost their lives in open water during the heatwave, including 13 children, according to reports. Swimming in rivers, lakes or the sea can present unexpected challenges even to strong swimmers. The Royal Life Saving Society warns that 90 percent of accidental drownings in the last five years have occurred in open water.

Dangers of Open Water Swimming
Alongside unpredictable depths, uneven banks and riverbeds, and a lack of safety equipment, there are many factors that make open water swimming dangerous. Unexpected currents and cold temperatures are two major factors in accidental drowning, the RLSS reports.
The cold water shock 'gasp reflex' is triggered when children and adults enter the water, according to The Outdoor Swimming Society. If someone jumps in, they may inhale water as they gasp. Enter the water slowly, getting used to the temperature, and get breathing under control. More regular swimming leads to a better controlled gasp reflex.
Last year there were 202 recorded accidental water fatalities in the UK, per the National Water Safety Forum. Data showed a marked uptick in deaths between May and August. Though 2025's figures were lower than previous years, heatwaves bring increased risks around open water, which remains colder than people often expect, causing swimmers to go into shock with deadly consequences.
