Swimming and diving:

pools and open water

Swimming pools

Take extra care - there could be things like wave machines that you’re not aware of, especially at leisure centres and holiday resorts. 

  • Follow safety signs and pool rules.
  • Check out the water depths.
  • Never dive into the shallow end.
  • Don’t leave children unattended. See our water safety advice for parents.
  • Keep trip hazards away from the edge of the pool.
  • Don’t drink and swim. See our advice on alcohol and water safety.

Open water swimming

Swimming in open water can be a great way to exercise and enjoy the outdoors, but it's very different from swimming in a pool and can catch people by surprise. Accidental drownings often occur at places like rivers, lakes, canals, flooded quarries and reservoirs.

Swimming in a group or at an organised event is safer.

  • Never swim alone.
  • Swimming in unsupervised locations increases the risk – they may have hidden dangers.
  • The water can be colder and deeper than you think or have strong currents and unpredictable river flows.
  • Be aware of cold water shock.

Diving and tombstoning

Tombstoning might seem like fun but jumping or diving from a height such as a pier, bridge or cliff is very dangerous.

  • Don’t jump into the unknown!
  • Rocks or submerged objects may not be visible, but they can cause life changing injuries if you jump onto them.
  • Water depths change with the tide – the water may be shallower than it looks.
  • Cold water shock can make it difficult to swim.
  • Conditions can change rapidly - strong currents can sweep people away making it impossible to get out of the water.
