Why should visitors take red flags at Karon Beach especially seriously during the rainy season?

Karon can develop powerful surf and rip currents during the southwest monsoon. Phuket provincial figures reported in June 2026 identified Karon as the island's deadliest beach over the 2024-2026 period, with 20 drowning deaths. That history is a strong reason to treat every red flag as a no-swimming instruction, not a general suggestion.

Use lifeguarded sections where available, keep children out of breaking surf when conditions are uncertain and do not assume another person in the water proves it is safe. Strong swimmers are also vulnerable to rip currents. When red flags are flying, choose a hotel pool, an indoor activity or a sheltered alternative rather than trying to find a gap between waves.
