Three people and a dog were rescued after becoming trapped in mud at Crosby beach on Saturday afternoon.
The incident prompted a multi-agency response involving Wirral Coastguard Rescue Team and HM Coastguard Crosby.
RNLI Crosby Beach Lifeguards and Merseyside Fire and Rescue Service also attended the scene to assist with the rescue operation.
The coastguard has now issued a warning to beach-goers amid the warm temperatures this weekend.

The incident occurred during a weekend of warmer temperatures which had attracted many visitors to coastal areas.
Authorities noted that mud can become particularly hazardous when combined with tidal conditions.
Following the incident, Wirral Coastguard Deputy Station Officer Paul Ambrose issued a stark warning to those visiting beaches during the warm weather.
He said: "Mud can be extremely dangerous. Once you're stuck, it's almost impossible to get out without trained rescuers."
"Rising tides can quickly turn a bad situation into a life-threatening one."
Ambrose emphasised the importance of contacting emergency services immediately in such situations.
"If you see someone in danger, call 999 and ask for the Coastguard," he advised.
