The body of 37-year-old Azzam Udda, who drowned Saturday off the coast of Caesarea, was pulled out of the water at the Jisr e-Zarka beach, near Atlit, on Sunday morning.
Magen David Adom paramedics pronounced his death on the scene.
Early on Sunday morning, large police forces resumed searches for his body, which had begun on Saturday evening.
Udda's father-in-law Marwan Bisami, 49, and 48-year-old Avi Constantine from Binyamina drowned on Saturday after trying to rescue Azzam.
Magen David Adom teams attempted to resuscitate the two but were unsuccessful.
