American citizen James Everett du Bois was at the beach with his wife and 3-year-old son, explained Rawai Mayor Aroon Solos.
While in the water, the family encountered a strong rip current. The wife was able to make it back to the beach, but Mr du Bois was dragged out to sea, Mayor Aroon said.
Lifeguards immediately launched a search for Mr du Bois, but were unable to find him.
A more intensive search was launched by rescue workers from the Kusoldharm Foundation last night, but also was unable to find him.
The search was called off at 8:30pm due to the strong waves and weather conditions, Mr Aroon said.
So far today there have been no updates as to the search efforts.
