Volunteer rescuers on Llandudno's inshore lifeboat Dr Barbara Saunderson were requested to take to the water by HM Holyhead Coastguard at 11.24am today.
The crew of three were asked to search and locate a person who had been seen in the sea approximately 200 metres off Llandudno Pier.
The D class inshore lifeboat made exceptionally good time in very challenging sea conditions to reach the casualty as quickly as possible. The crew were then able to make a recovery from the water and provide first response casualty care.
Returning to shore the lifeboat met the emergency services located at the Old Slipway on Llandudno Promenade. The casualty was transferred into the care of paramedics before being taken to hospital.
Lifeboat Operations Manager Marcus Elliott said: "This has been a very challenging service in which our volunteer crew performed their duties admirably in very difficult circumstances with the high winds prevailing offshore."
