Three teenage girls were rescued this evening when they were surrounded by water on Sandymount Strand after getting lost in fog.
The girls had been out walking when a heavy fog rolled in.
They became disoriented and were cut off by the incoming tide.
One of the girls used her mobile phone to call for help.
The Dún Laoghaire inshore lifeboat was launched at 6.22pm with the all-weather lifeboat launching shortly afterwards.
Gardaí and the Dún Laoghaire Coast Guard Unit coordinated the search from the shore.
The lifeboat crew said visibility was just 100m.
Shortly after the rescue mission was launched, the girls heard calls from the shore-based team.
The inshore lifeboat was then alerted to their location and the girls were then rescued.
They were extremely cold, and were met at the lifeboat station by paramedics to be assessed.
Commenting on the callout, Dún Laoghaire RNLI Coxswain Mark McGibney said: "The teenagers were out for a walk when they were caught out by a rolling fog and a fast incoming tide.
"They lost their bearings and were quickly surrounded by rising water. Thankfully they stayed calm and called for help.
"Our lifeboats were launched in minutes and assistance was also given by the Gardaí and local Coast Guard.
"If they had walked in the wrong direction they could have quickly become out of their depth, instead they made the right decision and called for help. In this case thankfully it ended well."
