The Wild Swimming Boom Is Real — And It’s Wonderful
Something remarkable is happening across the UK. From the lochs of Scotland to the rivers of the Lake District, more people than ever are swapping chlorinated pools for the exhilarating embrace of natural water. Wild swimming has shifted from a niche pursuit favoured by hardy enthusiasts into a genuine mainstream movement, with dedicated open-water venues, family-friendly events, and surf camps now popping up all over the country.
This is fantastic news. Swimming in natural water offers benefits that no leisure centre can replicate — a deep connection with the landscape, a powerful boost to mental wellbeing, and the kind of full-body invigoration that leaves you buzzing for hours. But as the community grows, so does the responsibility we all share to swim thoughtfully and safely.
Why Water Quality Matters More Than Ever
When wild swimming was a pursuit of the few, its impact on natural water bodies was minimal and the risks were largely understood by experienced swimmers. Now, with thousands of new participants taking their first dips each summer, the conversation around water quality has never been more important.
Natural water is not sterile. Rivers, lakes, and coastal inlets can carry a range of bacteria, including E. coli and Enterococci, often as a result of agricultural runoff, sewage overflows, or simply high volumes of wildlife in the area. These pathogens aren’t always visible — a crystal-clear loch can still harbour bacteria that cause stomach upsets, ear infections, or more serious illness.
The good news is that testing the water before you swim is now easier than ever. Home water quality test kits allow you to check your favourite spot quickly and confidently, giving you the information you need to make an informed decision about getting in.
What Increases Bacterial Risk in Natural Water?
- Heavy rainfall: Downpours can wash agricultural waste and sewage overflow into rivers and lakes, causing bacterial counts to spike dramatically.
- Warm weather: Higher temperatures encourage bacterial growth, particularly in shallow, slow-moving water.
- High footfall: Popular spots that see lots of swimmers, dogs, and general visitor traffic can see elevated contamination levels.
- Agricultural land nearby: Fields used for livestock near waterways are a significant source of E. coli and other bacteria.
Wild Swimming With Children: Extra Caution Required
The rise of family-oriented wild swimming events and summer camps is a joy to see. Introducing children to open water builds confidence, a love of nature, and physical resilience. However, children are generally more vulnerable to waterborne illness than adults — their immune systems are still developing, they’re more likely to swallow water, and they tend to spend longer in the water.
If you’re planning a wild swim with children, it’s worth taking a few extra precautions:
- Check local water quality reports from the Environment Agency or SEPA before visiting.
- Avoid swimming for 48 hours after heavy rain, especially in rivers.
- Choose established venues where water quality monitoring is already in place.
- Carry your own water quality test kit so you can assess conditions on the day.
- Ensure children shower or rinse off after swimming and wash hands before eating.
How to Choose a Good Wild Swimming Spot
Not all open water is equal. When scoping out a new location, look for water that flows freely rather than stagnates, swim upstream from any agricultural land where possible, and pay attention to any signage from local authorities. Online communities and wild swimming guides can be invaluable resources, but conditions change — what was safe last month may not be safe today.
This is where routine testing becomes a genuinely useful habit rather than an occasional precaution. Testing the same spot across different seasons and weather conditions builds up a picture of how the water behaves over time, making you a more informed and confident swimmer.
Join a Growing, Safety-Conscious Community
The wild swimming community is one of the most welcoming and passionate outdoor communities in the UK. As it grows, there’s a real opportunity to set a standard — to show that enthusiasm for open water and a commitment to safety go hand in hand. Experienced swimmers have a role to play in sharing knowledge with newcomers, and venues have a responsibility to provide clear information about water quality at their sites.
Whether you’re a seasoned dipper or planning your very first open-water adventure this summer, knowledge is your best companion. Understand the risks, test where you can, and swim with confidence.
