Lifeguards at St Ouen's Bay have rescued 20 people who have been caught out by rip tides in front of the Watersplash since Tuesday 23 July.
People are being urged not to go into the water between El Tico and the Watersplash when there is no lifeguard cover, and when there is, just to swim in the designated areas.
The flag zones are operation from 10am – 6pm everyday throughout the summer. Jake Elms from RNLI Lifeguards Jersey explains what they mean...
Currently there are deep sandbanks in front of the Watersplash which are causing the rip tides.
Inexperienced swimmers are being urged to go to a different beach in the evenings, or to go in the water in front of Le Braye rather than the Watersplash.
The lifeguards are present at St Brelade’s, St Ouen’s, Plemont and Greve de Lecq from 10am - 6pm every day.
