As the weather finally starts to heat up, you might be tempted to cool off in your local river, lake or popular sea swimming spot.
However, the delay of the men’s triathlon at the Paris Olympics due to pollution in the River Seine shows how nature can intervene with these plans.
Wild swimming has lots of health benefits but it also comes with risks, so here are a few extra checks you should consider before taking the plunge.
Brush up on local knowledge
“The best way to find out if the water quality is good enough to swim in is through local knowledge,” says Dominic Johnson, owner of Wild Swimming Tests.
“Some lakes have companies running the open water swimming venue and they will take care of safety,” adds Johnson. “Alternatively, if there are rangers [present] you can ask them.”
In addition, Kate Rew, founder of The Outdoor Swimming Society, recommends keeping an eye out for noticeboards nearby.
“Most beaches (and an increasing number of inland spots) have noticeboards at their entrances warning of local hazards and [also] give guidance. Read them,” advises Rew.
Check Swimfo
The Environment Agency tests water samples from designated bathing sites across England and then uploads the results onto Swimfo.
“Water quality in the UK is determined based on the amount of bacteria present in each bathing area,” explains Dane Westwood, water quality and sewer specialist at RS Bonds. “By using the [Swimfo] resource before visiting coastal or inland waters, you can avoid areas and times when the water quality might be temporarily low.”
Popular wild swimming spots are classified as either excellent, good, sufficient or poor which helps the public make informed decisions about where to swim.
“The Environment Agency collaborates with the Met Office to predict pollution risks, taking into account factors like weather conditions that might temporarily degrade water quality,” adds Westwood. “When forecasts indicate reduced water quality, pollution risk warnings are issued, and advice against swimming is displayed on Swimfo and signs at the beach.”
