The RNLI is urging people visiting the Welsh coast to take extra care as warmer weather and offshore winds are forecast across parts of Wales.
With temperatures expected to rise and more people heading to beaches, the charity is encouraging anyone planning to enter the water to choose a lifeguarded beach where possible.
The warning comes as easterly winds are expected in parts of Wales, creating offshore conditions on west-facing coastlines. The RNLI says these winds can quickly push people away from shore, particularly those using inflatables or stand-up paddleboards.
Chris Cousens, RNLI Water Safety Lead in Wales, said: “In parts of Wales, the forecast for the weekend and early next week is predicting moderate easterly breezes, which will mean offshore winds at westerly facing coastlines that can blow you out to sea.
“For beachgoers, using inflatables like stand-up paddleboards during these conditions is not advised, as they can very easily be swept away from the shore into deeper waters and away from the safety of the beach.”
He added that anyone unsure about conditions should speak to a lifeguard or seek local advice before heading onto the water.
The warning follows a recent rescue by Llandudno RNLI volunteers, who helped two paddleboarders who were blown more than a mile offshore from Rhos-on-Sea during strong south-easterly winds on June 27.
Working with HM Coastguard and Llandudno Coastguard Rescue Team, the lifeboat crew located the pair as they drifted towards the Gwynt y Môr wind farm. Unable to paddle back against the wind, both people and their boards were brought safely aboard the lifeboat and returned to shore.
The RNLI is reminding paddleboarders to wear a suitable leash and buoyancy aid, carry a means of calling for help such as a mobile phone in a waterproof pouch, and know to call 999 or 112 and ask for the Coastguard in an emergency.
The charity is also highlighting the dangers of cold water shock, warning that despite warmer air temperatures, the sea can remain cold enough to cause a sudden reaction if people fall in or enter deep water quickly.
Chris Cousens said visitors should remember the RNLI’s Float to Live advice if they get into difficulty in the water.
“Instinctively, most people who find themselves struggling in the water will begin to panic, swim, or thrash about,” he said.
“We’re urging people to ignore this instinct and remember to float. Tilt your head back, with your ears submerged. Relax and try to breathe normally.”
The RNLI says floating first gives people time to regain control of their breathing before deciding their next move, whether that is calling for help or swimming to safety.
The charity is encouraging everyone enjoying the Welsh coastline this summer to stay aware of conditions, respect the sea and visit a lifeguarded beach whenever possible.
