A record May heatwave has raised the risk of open-water incidents across the UK and Ireland. This page answers the most common questions people search for when heat hits the headlines: what the heatwave looks like, why drownings rise, how to stay safe around open water, and which regions face the highest risk. Read on for concise, practical guidance you can use right away.
Reports show a record-breaking May heatwave with high temperatures increasing outdoor activity near rivers, lakes, and coastal areas. As more people seek cooling in open water, safety risks rise—especially for cold-water shock and fatigue. Stay aware of local weather and water conditions, and follow any regional safety advisories.
Drownings rise as more people swim to cool off, often without proper supervision or awareness of water conditions. Cold-water shock can strike quickly, reducing ability to breathe and swim. Prevent by gradually acclimating to water, wearing life jackets where advised, avoiding swimming alone, and knowing the signs of distress.
Always supervise children within arm’s reach near water. Choose designated swimming areas with lifeguards when possible. Use a buddy system, wear a properly fitted life jacket for non-swimmers, avoid alcohol, and stay out of the water if you're tired, unwell, or have consumed substances that impair judgment. Have a plan for emergencies and carry a phone in a waterproof case.
Coastal and inland water sites across the UK and Ireland are seeing elevated risk during heat, with authorities issuing advisories on water safety, cold-water shock awareness, and swift-water rescue precautions. Look for official guidance from local emergency services, the RNLI, and lifesaving charities for region-specific safety tips.
Check reputable sources for current weather and safety alerts, including the Met Office, RNLI warnings, and local council advisories. Follow social posts from emergency services and charity organizations for up-to-date tips, closures, or changes to open-water access in your area.
Call emergency services right away. Do not enter the water unless trained to perform a water rescue. If you can reach the person with a long object or throw line, guide them to safety from the shore. Once out of the water, provide warmth and monitor for signs of cold-water shock or breathing difficulties until help arrives.
The deaths prompted the RNLI to warn of the "very real risk" of swimming in open water - as Tuesday saw the hottest ever May day recorded.
