NEWHAVEN Coastguard was called to the rescue of two 13-year-old boys when they got into difficulties in the sea.
Station officer Trevor Cutler said the current had been strong, the sea had been rough and the water was cold at this time of year.
He is urging young people to swim under supervision and tell people that they are going into sea.
The Coastguard was called to their rescue at Seaford Beach on Friday May 20.
By the time they got there some members of the public had thrown them a life ring.
A surfer realised what was going on and brought the boys to shore.
Trevor said: “One of them had mild hypothermia.They are very lucky that quick thinking members of the public saved them. It could have ended in quite a nasty incident.”
During the early summer young people getting into trouble in the sea can be a problem when the tide is rough and the water is cold.
Sussex Police and South East Coast Ambulance Service were called. One boy was taken to hospital with hypothermia whilst the other was checked over at the scene.
In an emergency call 999 to reach the Coastguard.
Trevor is planning to visit Seaford Head Community College to give the pupils a talk about the dangers of swimming in the sea.
