The seasonal pattern for Palau — what each stretch of the year tends to bring, and what to plan around. Guidance, not a forecast.
Seasonal pattern, not a forecast — conditions vary; verify tides, weather and visibility locally before you go.
Palau sits just north of the equator, so the water stays warm all year and temperature is rarely the deciding factor. The drier, calmer stretch is broadly December to April, when the trade winds settle and boat days are most reliable; the wetter months, broadly July to October, bring more rain and more unsettled weather, and the country sits near the edge of the western Pacific typhoon belt. Tides decide the good sites more than the month does: the channels work on a specific flow, and the wrong tide means no snorkel there at all, while the sheltered Rock Islands bays are workable in most conditions. Verify current conditions, permits and any closures locally before you commit a boat day.

Palau packs an unusual range into a small island group: drowned limestone Rock Islands with shallow, sheltered bays inside them, a marine lake you can snorkel among golden jellyfish, and channels where the tide carries sharks and mantas past. Almost all of it is reached by boat, and Palau manages its water seriously — permits, a conservation pledge and local rules are part of the trip, not an afterthought.
