According to the National Maritime Authority (AMN), the water is currently improper for bathing.
“After receiving information from the Portuguese Environment Agency [APA], advising against bathing, the Captain of the Port of Olhão gave instructions to hoist the red flag on the beach, prohibiting entry to the water,” reads a note from AMN.
The authorities explain that the APA is monitoring the situation and that the ban will continue until the water results indicate that the microbiological values are within the reference parameters.
