Wallis & Futuna Weather in May

May in Wallis and Futuna marks the beginning of slightly more comfortable conditions as humidity starts to ease, though the climate remains distinctly tropical. Daytime temperatures typically reach around 30°C (86°F), while nights stay warm at about 24°C (75.2°F), ideal for beach days and relaxed evenings.

Outdoor activities such as lagoon swimming and village exploration often feel more pleasant as conditions moderate, but staying hydrated and seeking shade during the hottest parts of the day is still recommended.

Sea Temperature in May

The surrounding South Pacific waters remain beautifully warm at roughly 29°C (84.2°F) in May, making them excellent for snorkelling, swimming and other marine activities.

Coral-rich lagoons and sheltered beaches provide outstanding opportunities to enjoy the islands' marine environment as the tradewinds begin to strengthen later in the season.

As Wallis and Futuna moves into the drier part of the year, May still offers plenty of daylight for outdoor adventures. Expect around 12 hours of daylight with several hours of sunshine, giving ample opportunity for beach trips, lagoon activities and scenic exploration between occasional tropical showers.

UV Levels During May

UV levels remain very high in May with a 9 UV index, so sun protection is essential. High-SPF, reef-safe sunscreen, hats and sunglasses help protect your skin while you enjoy the tropical outdoors. Seeking shade during peak midday hours is also recommended when spending extended time outside.

Rainfall in May in Wallis and Futuna decreases compared to the wetter months, though showers remain part of the tropical climate.

Around nine days of rain are typical, with approximately 273 mm (10.7 in) of rainfall overall.

Showers are often brief and heavy, clearing quickly to make way for sunshine, so outdoor activities and lagoon visits are still very much possible.

The islands remain lush and green, with waterfalls flowing and landscapes vibrant, but with fewer prolonged downpours than earlier in the year. May offers a good balance of tropical warmth and slightly more comfortable conditions for exploring the islands.

Tropical storms in May in Wallis and Futuna are highly unlikely, as the South Pacific cyclone season typically ends in April. Historical records show minimal cyclone activity during May, making it one of the more stable weather months for travel.

While the risk of tropical storms is very low, it is always sensible to monitor weather updates when travelling in the tropics, as isolated disturbances can occasionally form.

For travellers seeking the most predictable conditions, the mid-year drier months generally offer calmer and more consistent weather.

Be prepared for Wallis and Futuna in May by packing these few seasonal essentials:

• Swimwear
• Rash vest (we like the UV-protecting Sharkskin rashies)

• Flip-flops/jandals/sandals
