Palau in December — Full Picture
December sits in Palau's drier season but is dominated by the year-end holiday peak, with the steady 31°C/25°C heat and generally good conditions on the water. It is the busiest, priciest time to visit.
Seas tend to be settled and visibility good, so the Rock Islands and the signature dives are dependable — but flights, hotels and dive days fill up around the holidays, and Palau's limited capacity means you must book well ahead.
This is firmly peak season: expect higher prices and fuller boats. If you want the holiday window, reserve everything early; if you want similar conditions for less, the surrounding dry-season months can be better value.
Showers still occur and humidity is high. The Jellyfish Lake experience varies year to year — confirm conditions before buying the permit.
What to Wear & What to Pack
Dry-season warmth around 31°C/25°C, busy with year-end travel. Light clothing, swimwear, a rash guard and reef-safe sunscreen. UV is extreme (11) on every boat day.
