How to spot a rip current:

Here is a selection of photographs to show you what rip currents look like. Think of them as rivers of water that flow out to the back waves, and remember that they will not pull you under the water. Don't panic, swim to the side and wave for help to escape a rip. Look at the sea before you go for a swim - and look for the 'river of water' flowing out that will show you where the rip is.Please choose to visit a beach where lifeguards are on duty and swim between their flags.
