DYFED-Powys Police are concerned about Christopher Goldsworthy, aged 32, who has not been spoken to since around 5pm today (December 15).
Christopher was last seen kite surfing at Pendine Sands this afternoon. He was wearing a black wetsuit at that time.
Coastguard have carried out an extensive search of the water, however this has been stood down due to dangerous weather conditions.
We are appealing for anyone who may have seen Christopher, or has any information, to contact us by calling 101.
If you are deaf, hard of hearing, or speech impaired text the non-emergency number on 07811 311 908.
UPDATE: Police have confirmed that missing kite surfer Christopher Goldworthy has been found safe this morning.
After spending the night on marshes near Llansteffan, he made his way to the nearest house and has since spoken to police officers.
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.
