Main Hub
December settles into the more pleasant northeast trade-wind pattern with steadier weather, lower humidity and calm seas that suit day trips to the Rock Islands and snorkeling excursions. Holiday crowds increase around mid-December; book rooms early if you plan to visit over Christmas/New Year. Lightweight long-sleeve shirts for sun protection and a light rain jacket for an occasional squall will cover most needs.
Interior & North
December brings more stable weather with northeast trades returning, making Babeldaob’s interior comfortable for treks and cultural sightseeing. Rivers settle to normal levels and most secondary roads are easily passable-ideal for self-drive exploration of archaeological sites and waterfalls. Mosquito activity lessens compared with the wettest months, but a modest repellent and quick-dry clothing remain sensible.
Diving, Kayaking & Snorkeling
December frequently settles into calm, sunny weather with excellent lagoon clarity and steady northeast trades that keep conditions pleasant for multi-day boat trips. The Rock Islands see an uptick in visitors around the holidays, so plan ahead if you want early departures from Koror or a specific private anchorage. Lightweight reef-safe sun protection, a waterproof camera, and bookings for boat tours will serve you well.
Southern Historic Islands
December settles into a steady northeast-trade pattern with pleasing temperatures and calmer seas-ideal for visiting WWII sites and combining history with snorkeling on whichever shore you choose. Holiday travel increases slightly, so secure lodging ahead if you need specific dates. A sun hat, reef-safe sunscreen and comfortable walking shoes will cover most needs on these islands.
Kayangel, Ngarchelong
December’s steady trade winds and lower humidity make the northern atolls an appealing escape for remote snorkeling and uncrowded beaches, with stable boat schedules from Koror when sea conditions are average. Days are sun-drenched and winds help keep insects at bay, but pack a windbreaker for cooler mornings on exposed cays. If you want solitude, this month balances accessibility with comfortable weather.
Palau observes Independence Day on October 1; major national events are typically most active in the October period.
