- Thousands of people are injured or killed every year on Phuket’s highways. If you must rent a motorbike, make sure you at least know the basics and wear a helmet. Rental rarely includes insurance.
- Take special care on the roads from Patong to Karon and from Kata to the Rawai–Hat Nai Han area, where we've had reports of late-night motorbike muggings and stabbings.
- Women should think twice before sunbathing topless (a big no-no in Thailand anyway) or alone, especially on isolated beaches, as random sexual assaults can also happen.
- Avoid running alone at night or early in the morning.
During the May–October monsoon, large waves and fierce undertows can make swimming dangerous. Dozens of drownings occur every year on Phuket’s beaches, especially Laem Singh, Kamala, Karon and Patong. Heed the red flags signalling serious rips.
At any time of year, keep an eye out for jet skis when you're swimming. Although the Phuket governor declared jet skis illegal in 1997 and they were re-banned again in 2014, enforcement of the rule is another issue. Long-tail boats can also be hazardous as they come in close to shore. Do not expect the boatman to see you!
