A 32-year-old man spent a night wrapped only in his kite after going missing while kitesurfing at Pendine Sands, his mother has said.
Police issued an appeal for information after Christopher Goldsworthy was last seen off the coast of Carmarthenshire at around 5pm on Sunday.
On Monday morning, police confirmed he had been found safe and well.
Dyfed Powys Police said after spending the night on marshes near Llansteffan, he made his way to the nearest house and has since spoken to officers.
On Sunday evening bad weather meant the Coastguard search was called off, with family left fearing the worst.
Searches were resumed at first light on Monday and Mr Goldsmith was found ashore, near Pentowyn.
A spokesperson for Dyfed Powys Police said: "We would like to thank everyone who shared our appeal, and our colleagues at HM Coastguard and RNLI for their assistance in the search last night."
On Facebook his mother Wendy Goldsworthy wrote, "my son Chris has been found safe and well. Probably starving. He'd been blown into Llansteffan and spent the night wrapped up in his kite. Thank you to all friends and family plus huge thanks to HM Coastguard and Dyfed Powys Police, and RNLI who were all so involved in the search. It is such a massive relief."
