The RNLI lifeboat, Coastguard, police and ambulance service were all sent to the scene in Herne Bay shortly before 2.30am.
Whitstable RNLI says it launched after receiving a report that someone had entered the water near Herne Bay Clocktower.
But while en-route, the crew was informed the casualty was ashore with the Herne Bay Coastguard Rescue Team.
The Coastguard says it found them the beach.
