Free tool · Data from Freediving Koh Samui

Ocean conditions — Thailand.

Live wind, tide, wave, and visibility data for popular Thai dive sites. Use this to plan which days to head out — not which sites to hunt at.

Important — read before using

The sites shown in this widget are popular scuba diving sites. Almost all of them sit inside Thai national marine parks where spearfishing is banned. Use the wind, tide, and visibility data to plan your day — not to pick a hunting location.

For legal spearfishing waters near these sites, read our legality guide or message me with your coast and I will point you at legal alternatives with similar conditions.

Live ocean data

Sister brand · Apnea Total

Good days are wasted without the skill to use them.

Perfect conditions do not make you a hunter. Dive training does. When the wind drops and visibility opens up, the spearos who land fish are the ones who put the training in before the window arrived.
