CREWS from Barry Dock and Penarth lifeboat stations was launched after Milford Haven Coastguard was informed that four people had been cut off by the tide on Sully Island.
The call to respond came in at around 11.20am on Sunday, May 31.
On reaching Sully Island, the lifeboats located them with Barry Dock inshore lifeboat returning all four people safely to the shore to the waiting coastguard.
The Penarth lifeboat crew searched the rest of the island to ensure nobody else was on the island.
This was the seventh shout to Sully Island during the lockdown.

Barry Dock coxswain, Martin Bowmer said: “The danger of people being cut off by the tide on Sully Island is not that they are trapped on the island for six hours, but the strong possibility that if they try and return to the mainland they would get into serious difficulty.”
The RNLI advice for people in Wales is 'Stop. Think. Stay Safe.'
If you find yourself in difficulty or see someone else in danger call 999 and ask for the coastguard.
