On arrival, National Sea Rescue Institute (NSRI) teams and local authorities found and retrieved a body – believed to be a 39-year-old female – from Central Beach around 20 metres from shore.
It is believed the woman was on holiday from Cape Town to celebrate a public holiday.
According to local reports, the woman’s husband and child were on the scene.
A great white shark is believed responsible for the attack.
Witnesses said the mauling occurred in relatively shallow water.
“Then I just heard lots of screaming and saw people running out the water.
“’I then heard a woman had been attacked while swimming only two or three waves out so it was quite shallow but it was said nothing could be done to help her”.
Beaches have been closed in Plettenberg Bay by Bitou Municipality following the attack.
“The NSRI and the Bitou Municipality appeal to the public to be cautious along the Plettenberg Bay and Southern Cape coastline.”
NSRI noted there has been a spike in shark activity around beaches in the area.
“This is very unusual when compared with previous years.
“The Bitou Council in May approved research on a shark barrier at Central Beach.
“This study will go a long way to assist in understanding the behaviour of the sharks.”
The attack comes less than three months after another fatal mauling in the area in June.
In total there have been a total of 248 unprovoked attacks in South Africa since records started in 1905.
The majority of these have occurred in the Eastern Cape, 90 in KwaZulu-Natal and 55 in the Western Cape.
