Koh Wai Beach
You'll step from the boat onto sand so fine it squeaks underfoot, the entire beach stretching barely three hundred meters between fishing stakes and coconut palms. Moored longtails bob in the shallows, their captains napping in hammocks strung beneath deck canopies.

Questions people actually ask about Koh Wai Beach.
Is Koh Wai Beach safe for swimming and snorkeling?
Koh Wai Beach offers safe swimming and excellent snorkeling during the dry season from November to April when waters are calm, clear, and visibility is high. The reef areas near the shore provide good snorkeling but watch for sharp coral and sea urchins—reef shoes are recommended. During monsoon season (May-October), conditions become rough and potentially dangerous. There are no lifeguards on this small island, so swim within your abilities and stay aware of boat traffic. Always snorkel with a buddy and avoid touching or standing on coral.
When is the best time to visit Koh Wai Beach?
The best time to visit Koh Wai Beach is November through March, when weather is dry, seas are calm, and underwater visibility is excellent for snorkeling. December to February provides the most comfortable conditions with lower humidity and gentle breezes. April can be hot but still offers good beach weather. May to October brings monsoon rains, rough seas, and most accommodations close completely as boat access becomes unreliable. For the clearest water and best snorkeling, visit January through March when marine life visibility peaks.
