Polynesia in December: Weather, Crowds & What to Expect

Hawaii (Big Island, Maui, Oʻahu, Kauaʻi, Molokaʻi)

Holiday travel peaks and much of the state sees increased visitors; warm, wet spells alternate with clear trade-wind days on leeward beaches. Kona storms and occasional heavy showers on windward sides can complicate hiking plans, so carry rainproof gear and allow extra travel time between islands. If you prefer calmer, drier weather, target leeward beaches and book the popular attractions well in advance.

Equatorial & Low Atoll Belt (Tuvalu, Tokelau, parts of Kiribati & the Line Islands)

By late autumn the islands are shifting back toward the more stable trade-wind pattern, though heavy showers still occur and the risk window for cyclones is approaching. November typically requires travel flexibility and attention to weather bulletins, particularly when booking small inter-island flights. Expect communal resilience - emergency shelters and plans are familiar - but personal preparation is still essential.

Samoa & American Samoa

Late in the wet season showers gradually lessen in frequency, though the landscape remains saturated and lush; coral visibility improves as seas calm toward May. April often provides a quieter travel window before the main winter season, with fewer visitors and lower prices. Keep basic rainy-season precautions in mind and enjoy the island hospitality - villages and hosts remain welcoming year-round.

Tonga & Niue

By late autumn trades are re-established and the islands return to a stable rhythm of warm, breezy days and mild nights - a great time for coastal walks and exploring limestone coasts on Niue. May is a transition month toward the drier season; plan early bookings for whale-watching if visiting mid-year. Pack sun protection, reef footwear, and a lightweight windproof layer.

Central & Southern Polynesia (Cook Islands: Rarotonga, Aitutaki; Tahiti & the Society Islands; Austral Islands)

By late autumn the drier trade-wind pattern grows stronger and beach days become reliably sunny on most leeward shores; this is prime time for diving and island cruises. May is generally comfortable and less crowded than the peak mid-year months, offering good value on inter-island charters and guided hikes. Pack reef shoes, a windproof layer for evenings, and sunscreen for long days outdoors.

Eastern French Polynesia & Atoll Chains (Tuamotus, Marquesas, Gambier)

As the wet season starts to subside, brighter periods grow longer and calmer seas return - perfect for those who timed a late shoulder-season visit. April sees the Marquesas and Gambier islands offering good hiking conditions and clearer waters for snorkeling where runoff is minimal. Plan for rustic comforts on many atolls and pack gear to protect personal items from intermittent heavy rain.

Remote Eastern Outliers (Rapa Nui / Easter Island & Pitcairn)

Peak warmth and longest daylight happen during this month, with warm daytime temperatures that make dawn moai photography and cliff-top sunsets especially pleasant. December is a popular month for holiday visitors to Rapa Nui; book accommodations early and expect cultural events and higher local activity. Pitcairn stays extremely remote with limited berths for visiting yachts - plan with long lead times and accept simple conditions.
