Minister Suchart Chomklin Expresses Concern for Tourist Safety, Orders Coastal Monitoring Following Bluebottle Jellyfish Wash-Up at Karon Beach in Phuket

On 28 May 2026, Mr. Suchart Chomklin, Minister of Natural Resources and Environment, instructed the Department of Marine and Coastal Resources (DMCR) to closely monitor, conduct surveillance, and issue warnings regarding marine hazards that may affect the public and tourists, particularly during the monsoon season, in order to enhance safety and reduce risks from marine-related dangers.

The Department of Marine and Coastal Resources, through the Upper Andaman Marine and Coastal Resources Research Center, received reports from local monitoring networks and beach lifeguards regarding the presence of Bluebottle jellyfish (Physalia sp.) washed ashore at Karon Beach on the western coast of Phuket. Officials immediately deployed teams to inspect the area.

The inspection found that strong winds and waves measuring approximately 2–3 meters were present at the time of the incident. Bluebottle jellyfish with umbrella sizes of around 2–3 centimeters were found scattered along the beach. Surveys conducted from the high tide line to the low tide line recorded an average density of 0.5 jellyfish per 100 square meters.

Bluebottle jellyfish are venomous marine creatures that can cause severe stinging pain upon contact. In some cases, victims may experience chest tightness and breathing difficulties. However, no injuries related to the incident have been reported so far.

Authorities have issued warnings to residents, tourists, and tourism operators along Phuket’s western coastline to exercise caution and avoid contact with the jellyfish. Officials are also coordinating with local networks and lifeguards to strengthen surveillance and preparedness in assisting people affected by jellyfish stings, while also promoting public awareness of basic first-aid measures. Increased sightings of washed-up jellyfish are possible during the monsoon season.
