The young man who died after getting into difficulties swimming off Howth was a medical student in his final year.
Ali Hejazi, who was from Saudi Arabia, was pulled from the water off Hidden Beach near the Baily Lighthouse on Friday afternoon.
Following a 999 call the Irish Coast Guard tasked the Howth Coast Guard Rescue team along with Howth RNLI lifeboat and Coast Guard helicopter Rescue 116.
The Coast Guard rescue team arrived on scene and brought the man ashore where he was treated by paramedics from Dublin fire brigade and the National Ambulance Service.
Coast Guard Rescue 116 winched the man aboard and transferred him to a waiting ambulance where he was brought to Beaumont Hospital.
He was pronounced dead a short time later.
In a statement the Royal College of Surgeons Ireland (RCSI) confirmed the young man, who was 26-years-old, was due to complete his studies at the college later this year.
“RCSI is deeply saddened to learn of the death of Mr Ali Hejazi, final year medical student, who passed away following a tragic drowning accident yesterday,” a spokesperson said.
“We extend our deepest sympathy to Ali’s family and friends at RCSI.
“Unfortunately, due to current restrictions we cannot gather together as a community at this time.
“However, a range of supports have been put in place for our students.
“The college flags are flying at half-mast as a mark of respect to Mr Hejazi.
“May he rest in peace.”
