Council leaders are warning casual swimmers to be aware of the risk of drowning when taking to the sea during the hot weather.

The warning follows forecasts of searing sunshine set to grace the county over the next week.

The Local Government Association, which represents councils across England and Wales, is urging people to keep safe in the water and learn what do in case of an emergency ahead of the heatwave.

In 2021, 277 people died as a result of accidental drowning, which was an increase in 23 deaths from the previous year.

Councils are urging everybody to be vigilant to the dangers of drowning, especially parents with children.

People are being warned particularly of the risk of cold-water shock, which is one of the biggest causes of drowning.

Even strong and confident swimmers can struggle and drown after jumping into cold and unpredictable seas, rivers, canals and lakes where temperatures can be as low as 15C in the summer - half that of typical swimming pools heated to 30C.

The warning comes ahead of the second annual World Drowning Prevention Day on 25 July. This year’s theme is ‘Do one thing to prevent drowning’ and encourages people to share safety advice, take swimming lessons and support local downing prevention groups and charities.

Cllr Nesil Caliskan, Chair of the LGA’s Safer and Stronger Communities Board, said: “In a heatwave, one of the first things people do is flock to their local bathing spot to cool off and what might look like a safe place to take a dip or have a swim could in fact be a danger.

“Councils want to make sure everyone is safe around water, which is why we are urging people to follow our advice to be careful and vigilant to the dangers.

“Our advice is to brush up on your water safety skills and always swim in water that is clearly marked as safe and under the control of a lifeguard. Swimming in unknown water could lead to tragic consequences.”

The met office is forecasting sun all weekend in Falmouth, Helston and Truro with highs of 23 degrees.
