Police in South Wales investigating the disappearance of missing Glasgow teenager Hollie McClymont say a body has been recovered from the sea near Fontygary.
Rescue craft and foot patrols and helicopters have combed the shoreline on either side of Whitmore Bay.
"It must be so terrible for the family at this moment. My heart goes out to them," said Barry resident Sue Voss, of Pencoedtre on Monday.
She said local people were aware of the potential dangers of the sea and knew that tides could be treacherous.
"The tides are dangerous here, you can get pulled out to sea. That is why you should always stay between the red and yellow flags," she said.
"If you are from somewhere inland it is easy to think that there is no danger. On a sunny day it all looks so inviting."
She said a friend lost her dog several years ago when it went into the sea at nearby Knap beach and was washed away by currents.
