Met Office issues alert for anyone heading to coast this week

The Met Office has issued a warning for anyone planning to take a dip to beat the heat. The weather service has shared crucial safety guidance for those swimming in cold water. With an ‘Extreme Heat’ alert in place for many regions across England and Wales this week, beachgoers should remain alert to potential hazards.

The Met Office website states: “People heading to the coast should be mindful that sea-surface temperatures are not as high as they would be in mid-summer.” The meteorological service has also reiterated advice shared by the RNLI.

Samantha Hughes, National Water Safety Partner at the RNLI, said: “With warmer weather approaching, it’s important to remember that the water is still cold. Entering it unexpectedly can lead to cold water shock, causing a sudden increase in breathing and heart rate, which may trigger panic.

“If you find yourself struggling in the water, remember to Float to Live: tilt your head back so your ears are submerged, relax and control your breathing. You may need to gently use your hands to help you stay afloat, and it’s ok if your legs sink—everyone floats differently.

“Where possible, always choose a lifeguarded beach, and swim between the red and yellow flags. In a coastal emergency remember to call 999 for the coastguard.” Beachgoers can check tide times, wave heights and sea-surface temperatures using the Met Office app.

The Met Office continued: “If you’re planning on enjoying the water, here are three simple ways you can help keep yourself safer: 1. Check the water temperature, our seas and river temperatures are low enough to cause cold water shock when 15°C or lower

“2. Wear a wetsuit if you plan on spending any length of time in the water. 3. Wearing a life jacket or swimming buoy can increase your chances if you experience cold water shock.”

More information about cold water shock is available on the RNLI website. “Anything below 15°C is defined as cold water and can seriously affect your breathing and movement, so the risk is significant most of the year.

“Average UK and Ireland sea temperatures are just 12°C. Rivers such as the Thames are colder – even in the summer,” the experts said.

“Cold water shock causes the blood vessels in the skin to close, which increases the resistance of blood flow. Heart rate is also increased. As a result, the heart has to work harder, and your blood pressure goes up. Cold water shock can therefore cause heart attacks, even in the relatively young and healthy.”

People heading to the coast should also be aware of the risks of spending time outdoors during the heatwave. The NHS advises staying in the shade, especially between 11am and 3pm. If you do go outside, wear sunscreen, a hat and light clothes.
