Beach days are supposed to be all about warm sand, cooling swims and switching off in the sunshine. But relaxing by the sea becomes a very different experience when you are constantly scanning the water and shoreline for something that could leave you in agony.

That is the concern facing beachgoers in southern Spain after large numbers of Portuguese man o’ war have washed ashore at two popular beaches in La Línea de la Concepción. The striking blue-purple creatures may look unusual, but their long venomous tentacles can deliver an intensely painful sting, with victims describing a sudden burning sensation followed by severe pain and angry red marks on the skin.

Local authorities have issued a warning after mass arrivals were reported at Levante and Santa Bárbara beaches, urging residents and visitors not to touch the creatures, even if they appear to be dead on the sand.

Beaches under close watch

Municipal workers began removing the creatures from the shoreline after large numbers were spotted on the sand. Officials have warned beachgoers not to touch them under any circumstances, even if they appear dead, as their tentacles can remain venomous long after washing ashore.

Authorities believe recent weather conditions and sea currents have carried the jellyfish towards the coastline. They have warned that more could arrive over the coming days if conditions remain unchanged.

Although the beaches have not been permanently closed, visitors are being asked to remain vigilant and follow any instructions from lifeguards or local authorities.

Why Portuguese man o’ war are so dangerous

Unlike common jellyfish, Portuguese man o’ war can trail tentacles stretching several metres beneath the water’s surface. Their sting injects a powerful venom that causes immediate, intense pain and can leave raised red welts on the skin.

Most stings are not life-threatening, but some people can experience severe allergic reactions, breathing difficulties or other medical complications requiring urgent treatment. Children, older people and anyone with underlying health conditions are considered more vulnerable.

Experts stress that even detached tentacles or stranded specimens should never be handled.

What to do if you are stung

If you are stung, experts recommend leaving the water immediately and rinsing the affected area with seawater rather than fresh water, which can trigger more venom release. Any visible tentacles should be carefully removed using tweezers or another object, avoiding direct skin contact.

Medical advice should be sought if the pain is severe, spreads beyond the sting site, or if symptoms such as difficulty breathing, dizziness or chest pain develop. Folk remedies such as vinegar or urine are not recommended for Portuguese man o’ war stings and may make the injury worse.

With warm summer seas continuing to attract beachgoers across Spain, authorities are reminding people to pay attention to warning flags and lifeguard advice. A quick glance along the shoreline before entering the water could help prevent a painful encounter with one of the Mediterranean’s most dangerous marine visitors.

Families were still waiting at Girne port on Monday after a high-speed ferry bound for Turkey rolled over over off northern Cyprus, killing at least eight people. Search teams and Turkish divers were combing water more than 500 metres deep for passengers still unaccounted for.

The Filo Jet, a privately run Turkish-flagged catamaran of about 40 metres, left Girne (Kyrenia) for Tasucu in Mersin on Sunday, August 30, with 259 passengers and eight crew: 267 people in all. Most on board were Turkish citizens. Saturday’s sailing had already been held back because of poor weather. Departure on Sunday came at about midday.

How the ferry went down

Trouble started about 15 minutes out, roughly four nautical miles off Girne near Diana Beach. Officials say successive waves struck the double-hulled craft. Survivors later said the boat slammed onto the sea, the bow burst open and water poured in. A distress call followed. Passengers in lifejackets clung to the upturned hull or jumped into the water.

Coastguard boats, helicopters, the passenger ship Akgunler 3 and civilian craft pulled people off the wreck. By late afternoon Filo Jet had gone down, settling on the seabed at 514 metres. None of those brought ashore were described as critically injured in later briefings. Officials put the rescued at about 237 to 242. Missing tallies still differ, with some saying 18 and others 19.

At the port, relatives sat in silence or scrolled news sources on phones for names.

Crew held as search goes on

The captain and seven crew are in custody. Northern Cyprus authorities declared three days of mourning and cancelled August 30 Victory Day events. Weather, the decision to sail and the condition of the vessel are all under inquiry. Divers from Turkey have joined night searches with helicopters, drones and extra ships.

Girne–Tasucu is one of the daily sea shuttles between northern Cyprus and the Turkish mainland.
