A man and his daughter escaped injury when they were rescued as waves crashed over a pier.
The pair were walking on the east pier at Howth, near Dublin, at high tide when they got stranded and were forced to take shelter from breaking waves.
Fred Connolly, of Howth RNLI, said they were lucky to have taken shelter as they would have most definitely have been washed into the sea while trying to make their back.
“We would urge caution when people are out walking near exposed areas such as piers or cliffs as the waves can be quite high and powerful,” he said.
There was no serious injury but the pair were extremely cold and wet, it added.
The alarm was raised as dangerously surging sea caused waves to crash over the harbour making it unsafe to walk in.
The inshore lifeboat was launched with a crew member getting on to the pier and walking the man and girl, who is believed to about eight years, safety back to the lifeboat.
Earlier, a lone sailor had to be airlifted from a yacht when he got in to difficulties.
The dramatic rescue happened shortly before 7am approximately 38 miles east south east of Ballycotton off the east Cork coast.
The yacht was sailed by two crew members aboard and the Ballycotton RNLI.
