Portugal's maritime authority warns of winter sea dangers and urges coastal caution

A warning after the bathing season

The Autoridade Marítima Nacional (AMN), Portugal's national maritime authority, issued a public warning on Wednesday, 4 November, as part of its 'Mar de Inverno' (winter sea) awareness campaign. The bathing season has ended, and the agency says sea conditions at this time of year pose a higher risk on beaches, coastal areas, cliffs and port areas. The danger persists even on sunny days with mild temperatures. Sea conditions can change quickly, reshaping beach profiles and producing large waves that catch people in places that look safe.

Eight recommendations for the public

The AMN strongly advises people to avoid walks along the water and to stay out of areas exposed to breaking waves, such as harbour breakwaters, cliffs and surf zones. It recommends keeping a constant safe distance from the waterline and never turning one's back to the sea, since a sudden wave can arrive without warning. Bathing outside the season is also discouraged, because there is no permanent surveillance at this time of year. The agency asks people to check weather forecasts and sea-state warnings before travelling to the coast, and to consult them before any trip to the shore.

Who should take extra care

Parents are asked to keep children under constant watch and away from the water and the most dangerous zones. Recreational anglers who fish near cliffs or at spots often struck by swell are asked to take additional precautions. The maritime community is advised to reinforce mooring lines and to check regularly on boats that are tied up or anchored. Anyone who decides to go to sea alone should tell another person where they are going and when they expect to return.

The agency's message

The AMN's official website put the message plainly:

“The sea is no longer a summer sea. Even on sunny days with mild temperatures, sea conditions can change rapidly.”

The agency's closing statement in its SIC-reported release urged the public to respect the sea and to remember that a good outcome depends on their own behaviour:

“If the sea commands respect, why do we keep challenging it? Remember: a happy ending also depends on you.”

Emergency contact

The AMN reminds the public that weather forecasts and sea-state warnings should be checked before any trip to the coast. In any emergency at sea or on the shore, people should contact the number 112 immediately. The agency's guidance applies to beaches, cliffs, harbour areas and recreational fishing alike.
