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.
