Wallis & Futuna Weather in December

December in Wallis and Futuna brings full tropical warmth, with daytime temperatures typically reaching around 31°C (87.8°F) and evenings remaining mild at about 24°C (75.2°F).

Humidity is high, creating that classic island atmosphere, but ocean breezes and abundant opportunities to cool off in the lagoon help keep conditions comfortable.

Sea Temperature in December

The surrounding sea stays beautifully warm at roughly 29°C (84.2°F), making December an excellent time for swimming, snorkelling and other water-based activities despite the wetter conditions.

December in Wallis and Futuna still offers long, warm days with plenty of daylight for outdoor exploration. With around 13 hours of daylight and several hours of sunshine, it remains a good time for lagoon visits, coastal walks and cultural sightseeing.

Early mornings are often ideal for outdoor activities before humidity builds later in the day.

UV Levels During December

UV levels are extremely high in December, typically reaching 11+ on the UV index at midday.

Sunscreen is a non-negotiable; apply a high-SPF, reef-safe formula every couple of hours or after swimming. Lightweight, UV-protective clothing and a wide-brimmed hat are also smart for extra protection.

Sunrise and Sunset During December

December in Wallis and Futuna offers balanced daylight hours:

• Sunrise: Around 5:08 am at the start of the month, shifting to about 5:21 am by the month's end

December in Wallis and Futuna falls within the wetter part of the year, bringing humid tropical conditions and more frequent showers. Rain typically arrives in short bursts rather than prolonged downpours, so there are still plenty of opportunities to enjoy sunny intervals and outdoor exploration.

The islands receive around 347 mm (13.7 in) of rainfall during the month across roughly 12 days, which makes December one of the wetter periods but also one that enhances the lush, vibrant landscapes.

Despite the increased rain, the tropical climate remains warm and inviting for lagoon activities and cultural sightseeing when conditions allow.

Tropical storms in December in Wallis and Futuna are possible, as the South Pacific cyclone season runs from November through April.

While cyclones are not an everyday occurrence, the risk is higher during this period due to warmer sea temperatures and increased atmospheric moisture.

The territory has experienced significant storms in the past, including historical cyclones in 1946, 1957, 1986 (Cyclone Raja), 1991 (Cyclone Val), 2001 (Cyclone Waka) and 2012 (Cyclone Evan), demonstrating that severe weather events can occur during the wet season.

Travellers should stay informed about weather updates and follow local guidance during periods of heightened storm activity.

While direct hits are rare, it's wise to monitor local advisories and familiarise yourself with Cyclone & Hurricane Safety in Wallis & Futuna.

If you're visiting Wallis and Futuna in December, travel insurance and a flexible itinerary are highly recommended, just in case Mother Nature decides to stir things up.

December's lush landscapes and warm lagoon waters make it a rewarding time to explore the islands at a relaxed pace, especially with the added excitement of the Grand Christmas Fair in mid-December, a two-day celebration that brings together Pacific guests for a vibrant cultural exchange.

Other than Christmas Day (25th) and New Year's Eve (31st), it's business as usual on Wallis and Futuna.

Nature lovers should head to Lake Lalolalo, whose steep volcanic cliffs look especially vibrant during the wetter season. For history and sweeping coastal views, explore Talietumu (Kolo Nui), an important archaeological site reflecting the islands' history of Tongan occupation.

On Futuna, the Saint-Pierre-Chanel Basilica remains a significant cultural and spiritual landmark, while hidden gems like the Vainifao Cascade provide freshwater spots to cool off.

If you need to escape the rain, indoor attractions like Le Petit Musée des Fagāna and the Uvea Museum Association (American WW2 Museum) are well worth a visit, along with the 10 Things to Do in Wallis & Futuna on a Rainy Day.
