December is generally one of the wetter months with frequent tropical showers and high humidity; outdoor plans should remain flexible. Some visitors avoid the wettest months, while others find good local experiences between storms.

urban atolls
December’s weather is often unsettled with alternating clear breaks and intense tropical showers; temperatures remain warm and nights are muggy under cloud cover. Holiday travel picks up-families move between islands and ferry spaces fill-so book ahead if visiting South Tarawa during local festivities. Be mindful of rougher lagoon conditions during storms and the occasional coastal flooding on high tides.
Butaritari, Makin and surrounding islets
December is generally wet and humid with intense tropical showers and occasional gale‑force squalls; the atoll vegetation looks renewed but travel logistics are less predictable. Christmas and New Year see higher local travel as people return to family, which can crowd scarce transport options - book early. Bring waterproof gear, mosquito protection and patience for delays in this season.
Canton, Nikumaroro and the protected area
December is wetter and warmer with frequent squalls, though there are still clear intervals that reward those on patient voyages; expect wet decks and damp tents or station lodging. Services on Kanton are minimal and most visitors come as part of conservation or research trips; careful packing and flexible scheduling are essential for a successful visit. Bring waterproof gear for gear and electronics and anticipate sea transit delays.
Kiritimati/Christmas, Tabuaeran/Fanning, Teraina/Washington
December is warm, humid and often stormy with intermittent heavy downpours across the Line group; holiday travel to Kiritimati spikes, and accommodations can be hard to find without advance booking. The reefs can be murkier after rain, but birdlife and shorebirds are active in flooded flats which can be spectacular for observers. Factor in possible transport cancellations and bring multiple days of supplies when visiting remote atolls.
There are no major festivals or events in Kiribati during December to be aware of.
