An RNLI lifeguard at Tenby Castle Beach rescued a four-year-old boy on Wednesday afternoon after he was swept out on a wave while swimming in the sea.

The four-year-old boy was visiting the area with his family and had spent most of the day enjoying the beach near water's edge. 

At 3 pm, RNLI lifeguard Robin Knibb spotted the child out of his depth and being swept towards the rocks near St. Catherine's Island. 

The boy had been playing in the sea between the red and yellow flags when he was hit by a wave that swept him towards the rocks.

Robin spotted the child and paddled out on her rescue board to assist the boy. 

The four-year-old boy was quickly picked up by the charity's lifeguard and safely returned to shore.

RNLI lifeguards assessed the boy to check that he was OK and returned the child to his family.

Adam Pitman, RNLI lifeguard supervisor, said: "RNLI lifeguard Robin spotted the child in trouble and quickly responded to the situation. Even though the boy was swimming between the red and yellow flags it's easy for someone, especially a child, to get out of their depth. 

"Before enjoying the beach this Bank Holiday weekend, please keep in mind some essential safety tips: Try and visit a lifeguarded beach and always swim between the red and yellow flags; when arriving on the beach, please approach the lifeguards and ask for tips and advice to help ensure a safe and enjoyable day on the beach."

RNLI lifeguards provide a safety service on 32 of Wales' busiest beaches. The charity's lifeguards can be seen at their post between 10 am and 6 pm every day throughout the summer season.
