Thailand's Tourism Authority issues an elevated safety advisory for Phuket and Krabi coastal areas effective June 12 2026 due to strong rip currents and box jellyfish sightings. Authorities recorded 47 swimmer rescues and three fatalities in May prompting the update. Red flags now indicate no-swim zones at 18 popular beaches including Patong and Railay.
Local lifeguard teams increase patrols to 24 hours with new drone surveillance covering 12 kilometers of coastline. Tour operators must brief guests on safety protocols before water activities. The advisory aligns with monsoon season patterns lasting through October.
Background context includes similar warnings issued annually but intensified this year after climate-driven current changes. Phuket received 2.8 million visitors in the first quarter of 2026. Neighbouring Malaysia maintains standard yellow flag protocols on its east coast beaches.
What this means for you
Check daily flag status via the Thai Beach Safety app before entering water and swim only in green or yellow zones. Wear full-body rash guards to reduce jellyfish sting risk during snorkeling tours. Book hotels with private beach access for supervised swimming areas.
Avoid alcohol before swimming and never enter water after 1800 hours when lifeguards end shifts. Purchase travel insurance covering medical evacuation costing from 45 USD per week.
Conditions expected to improve by November with seasonal wind shifts.
