When to go (wind & weather)

Koh Tao is sail-able year-round, but expect the steadiest light winds and calmer seas most often from December–June. The NE monsoon (roughly Nov–Jan) can bring rain and choppier seas; operators switch routes to sheltered sides or reschedule for safety.

What to bring

  • Reef-safe sunscreen, hat, light cover-up, and a reusable water bottle (plastic disposables are discouraged on nearby islands).
  • Swimwear & towel; shoes you can kick off onboard.
  • Motion tabs if you’re sensitive to swell.

Good to know

  • Private sails are typically BYOB for alcohol; soft drinks/water often included.
  • Multi-day trips: confirm exact inclusions (meals, snorkel/SUP gear, park fees, hotel transfers).
  • For learning: consider a dinghy lesson first—quicker feedback loop and super fun in Sairee Bay.
