Is the tap water safe for kids?

No. Never drink tap water. Use bottled water for drinking and even for brushing teeth to avoid stomach bugs.

Are there lifeguards on every beach?

No. Major tourist beaches in Phuket have them, but many remote islands in Krabi or Koh Samui do not. Always check before your children enter the water.

Safely enjoy Thailand beaches with kids

Prioritize islands with lifeguard-patrolled beaches like Kata or Karon in Phuket to ensure water safety. Always use high-SPF sunscreen, provide shade during peak UV hours (11:00 AM to 3:00 PM), and stay hydrated with bottled water.

Check the flag system. Before letting kids enter the water, look for the flag on the beach. A red flag means no swimming due to dangerous currents; yellow means swim with caution; green means the water is safe. If you don't see a flag, ask a local vendor before wading in.
Identify jellyfish zones. Look for warning signs or netting in the water. If you see signs about box jellyfish, stay out of the ocean entirely. Keep a bottle of white vinegar in your day bag, as it is the standard first-aid treatment for stings while waiting for medical help.
Protect against high UV. The tropical sun is intense. Use SPF 50+ water-resistant sunscreen and dress children in UV-protective long-sleeved rash guards. A sun hat with a chin strap is essential to prevent heatstroke.
Manage local transport safely. Most tuk-tuks and songthaews (shared trucks) lack seatbelts. If traveling with small children, hold them firmly on the side away from traffic or bring a lightweight travel booster seat if you are taking private taxis.
