The swimmer disappeared on May 18 near the 10th Street beach after being struck by a wave and failing to resurface.
According to the missing man's father, he is from Exton, Pennsylvania, and is a student at Hofstra University.
Roughly two dozen people could be seen forming a human chain in the water to aid in the search.
A body has been discovered near where a swimmer who may have been attacked by a shark went missing last week. The swimmer was identified as 55-year-old Erica Fox.
The body of a missing swimmer was pulled from the water Thursday in Gloucester County, New Jersey.
The man said he was treading water for several hours until he was found by fishermen.
