Tourists visiting Thailand’s island of Phuket have been warned to avoid contact with jellyfish after a dozen venomous specimens were found washed up along a popular beach, prompting safety concerns among local authorities.
The alert was issued after around 20 to 30 moon jellyfish were spotted floating near the surface and stranded along the shoreline at Siam Bay on Ko Racha Yai, just off Phuket. Officials from Thailand’s marine authorities urged beachgoers to exercise caution and not touch the creatures, even though they are not considered highly dangerous.

Experts from the Department of Marine and Coastal Resources (DMCR) identified the species as moon jellyfish, or Aurelia sp, which are commonly found in Thai waters. While their venom is relatively mild and not life-threatening, it can still cause discomfort. Contact with the jellyfish may result in skin irritation, red rashes or a burning sensation, particularly for people with sensitive to their sting.
Authorities stressed that visitors should remain vigilant and avoid direct touch, adding that anyone experiencing unusual symptoms after contact should seek immediate first aid and medical attention, as reactions can vary.
While most stings from moon jellyfish are mild, symptoms such as persistent pain, swelling, or signs of an allergic reaction may require prompt treatment, and early medical care is recommended to prevent complications.
The appearance of the jellyfish has been linked to natural environmental factors, although authorities did not specify an exact cause. Such occurrences are not unusual in coastal regions, where changing sea conditions can bring marine life closer to shore.
Visitors who are stung are advised to clean the affected area and seek medical attention if symptoms persist or worsen. Officials also encouraged tourists to report sightings to local authorities to help monitor the situation and ensure public safety.

Authorities also issued first-aid advice for travellers exposed to jellyfish venom:
- Get out of the water immediately if a severe reaction occurs, as symptoms may worsen and increase drowning risk.
- Pour vinegar over the affected area, or rinse with seawater if vinegar is not available (avoid fresh water or other liquids).
- Do not rub or touch the area, as stinging cells may remain on the skin.
- Monitor for at least one hour, even if symptoms are mild, due to possible delayed reactions.
- Call emergency services on 1669 if severe symptoms such as breathing difficulties occur, and seek urgent hospital care.
- Begin CPR immediately if the person becomes unconscious or suffers cardiac arrest, until help arrives.
The warning comes as Phuket continues to attract large numbers of international tourists, particularly during peak travel seasons. Beaches in the region are known for their clear waters and marine biodiversity, but officials emphasised that awareness of potential hazards is crucial.
While the moon jellyfish do not pose a severe threat, authorities reiterated that avoiding contact is the safest course of action, as even minor stings can disrupt holiday plans and require medical care.
