PHUKET — 29 May 2026, Lifeguards have spotted Portuguese Man o’ War on several Phuket beaches, prompting warnings for tourists to stay vigilant along the Andaman coast.
A lifeguard at Kata Noi beach in Karon subdistrict first noticed the venomous marine creatures washed ashore on 28 May. Warning signs have since been erected along the beachfront.
Chaninton Nareepen, a lifeguard stationed at Kata Noi, said he spotted the creatures on 28 May and immediately put up warning signs along the full length of the beach.
Sightings have also been reported at Nai Harn beach, Yanui beach, and Racha Island, prompting authorities to step up monitoring across the area.
Despite resembling a common jellyfish, the Portuguese Man o’ War is a highly venomous marine organism with long tentacles that can deliver a painful sting even after the creature is dead. Contact can cause burning pain, swelling, rashes, nausea, difficulty breathing, or loss of consciousness, and can be fatal in some cases.
Authorities advise anyone who spots one not to touch it. Those stung should rinse the affected area with seawater — not fresh water — and seek medical attention immediately.
Tourists visiting Andaman coast beaches are urged to monitor official warnings closely before entering the water.
