West Kirby RNLI were called out at 11.48 am on Sunday following a 999 call reporting two adults and two children cut off on Hilbre Island by the incoming tide.
The family were from outside of the area and had checked the tide timetable but miscalculated the latest time that it was safe to leave the island prior to high tide.
HM Coastguard advised the family to remain in place until West Kirby RNLI lifeboat were able to reach them.
All 4 were recovered by the Lifeboat dry and uninjured and were handed over to awaiting Coastguard Rescue Officers at Sandy Lane slipway.
The family were relieved and grateful to both HM Coastguard and the volunteer RNLI crew for their rapid response.
Speaking following the call out, Richard Diamond, West Kirby RNLI Lifeboat Operations Manager said:
‘It is important to not only check the tide times but also to factor in the time required to walk the two miles to shore. We would recommend that you leave the island at least three hours before high water, or longer if any of your party walks slowly.
“It takes about one hour to cross the two miles. The casualties acted appropriately by contacting HM Coastguard who advised the party not to enter the water and quickly notified West Kirby RNLI.
“If you see someone in trouble, dial 999 and ask for the Coastguard”.
