What should you know before a day on the water? Cold water can catch out even strong swimmers, and conditions change quickly, so lean on your instructors.
This guide gives general information only. It is not training. Always follow the instructions of the qualified activity provider and the lifeguards or coastguard at the location.
Cold water shock
Cold water can cause a sudden gasp and fast breathing when you first go in. This is called cold water shock and it can happen even on a warm day. Wetsuits, buoyancy aids and a slow, controlled entry help. A good provider supplies the right kit and talks you through the first moments.
Tides and currents
The sea and rivers move. Tides change how far the water comes in and how strong the flow is. Rivers can rise quickly after rain. Providers who run these activities check the tide tables, river levels and weather before each session.
Kit that matters
Buoyancy aids or lifejackets, helmets for moving water and the right wetsuit are normal for most water activities. Ask what is supplied and what you need to bring.
What a good provider does
- Gives a clear briefing before you get in
- Matches the group to the conditions
- Keeps instructors in or near the water
- Has a rescue plan and trained staff
- Cancels or changes plans if conditions are poor
Coastal activities
For coastal activities such as coasteering, sea kayaking and surfing, the Maritime and Coastguard Agency and the RNLI publish guidance. Read their latest advice and follow flag warnings and lifeguard instructions.
If you get into difficulty
Stay calm, float on your back if you can, and signal for help. Follow the instructions of your guide.
In short:
- Cold water shock can affect anyone
- Tides and currents change, so rely on your instructor
- Check kit, briefing and rescue plans before you book
