Prévention baignade EN


Be careful to the tide timetable! When the sea is rising, strong currents come in basins and surround the sand banks.

When the sea is picking up, a strong current empties the basins and could sweep you away. Look after the flags at the first-aid post:

Red/Yellow: supervised bathing during the opening hours of the first aid post

Red: Bathing prohibited

Yellow: supervised bathing, danger

Green: supervised bathing, no danger

Supervised bathing area delimited:

  • to the south by the extension of Avenue Francis Tattegrain
  • to the North by the extension of Rue Lavoisier

Supervision is provided from 30 June to 2 September.

Quelques conseils... EN

  • Don't go too far from the shore, and don't overestimate yourself. Swimming in the sea can be dangerous due to currents and waves.
  • If you are caught in the current, do not swim against it but let yourself be carried to try to reach the beach.
  • In hot weather, avoid the 12-4pm time slot, especially with children. When swimming, get wet gradually to avoid thermal shock.
  • Remember to protect yourself and your children from the sun with sun cream, a hat or a cap. Moisturise regularly and apply cream every two hours.
  • Give the children a landmark (e.g. totems installed on the beach) and equip them with a bracelet with your telephone number.
  • Keep a constant watch on children on the beach as well as in the water, in case of emergency contact the sea rescue service at 196.
