One of the most dangerous places to swim, and not being a great swimmer I have never swam here, because of the under currents.
The rough seas in the Praia Formosa area led to the raising of the red flag on Monday afternoon.
Bathers who took advantage of the sun to go to the beach found themselves unable to access the sea due to the strong surf.
Doca do Cavacas has already flown the yellow flag.
