Phuket authorities were meeting at Phuket Provincial Hall in Phuket City this morning at a gathering chaired by Phuket Governor Maitree Intrusud to discuss the needless deaths.
Lifeguards rescued more than 100 people from Phuket's famous west coast beaches last week and today a spokeswoman asked for volunteers to help to stop the drownings.
In the latest tragedy, family and friends of Peerapon Nunark, 19, kept a vigil until darkness fell over Layan beach last night.
Today their hopes were dashed when the young man's body was found and recovered offshore of Phuket's west coast, where tourists from India, Belgium and Russia have also drowned since Thursday.
The succession of tragedies is likely to bring to a head continuing concerns that Phuket fails to do enough to prevent drownings in the dangerous onset of the monsoon season.
The deaths are certain to be raised when ambassadors from Europe, Australia and probably China meet with Thailand's Minister for Tourism and Sport in Bangkok on Friday.
The faces of Khun Peerapon's family and friends were filled with anguish as they stood hoping for his safe return at Layan beach yesterday.
His mother, Wasana Janpen, said: ''Peerapon was with five friends at the family picnic. We watched him wave for help. Then he was gone.''
She could not explain why the swimmers had chosen to ignore red flags and warnings from lifeguards. It's a common problem that occurs when people reach Phuket's beaches, determined to swim.
Water safety experts say that lifeguards are only one part of Phuket's needs to protect swimmers at this time of the year.
The four drownings in four days have been accompanied by other drownings and the death of one Chinese tourist from a speedboat propeller since May.
Eight tourists drowned on Phuket's beaches between mid-May and mid-July last year but this year it was again left just to the lifeguards to protect swimmers.
The water safety experts have called for warnings at Phuket airport, on arrival at resorts and guesthouses, and on the beaches for those who still plan on risking their lives.
