This was the fourth alert this week for Llandudno RNLI.
The D Class lifeboat Dr Barbara Saunderson launched at 10.25pm on Tuesday, June 8.
In darkness, the volunteer crew, along with colleagues from the Llandudno Coastguard Team, conducted a brief shoreline search before establishing the sighting was a paddle boarder returning to the beach and did not require assistance.
The emergency services were therefore stood down.
Luke Heritage, lifeboat station mechanic, said: "Although this soon turned out to be a false alarm with good intent the crews still have to respond to all eventualities and be ready to launch to all emergency calls."
