Members of the public spotted a person in difficulty in the sea near the Boating Pool at around 1.10am on Monday (August 1).
Crews from RNLI Blackpool launched one D-class lifeboat and quickly made their way to the scene despite the “very difficult” conditions.
HM Coastguard volunteers used torches to highlight the position of the casualty who was “being overwhelmed by waves when the lifeboat reached him.”
