Rainfall is a defining feature of Wallis and Futuna’s tropical marine climate, and showers are possible in all seasons.

The islands receive more than 3,000 mm (118 in) of rain annually, spread across the year, reflecting their lush and verdant landscapes. While there is a relatively wetter period from November to April and a slightly drier period from May to October, neither constitutes a true dry season.

During the wetter months, monthly rainfall often exceeds 300 mm (12 in), with short but intense tropical downpours common. In the drier months, precipitation typically decreases but still averages over 100 mm (4 in) per month, meaning showers remain a regular part of island life.

These bursts of rain are often brief and followed by sunshine, contributing to the region’s vibrant vegetation.

Microclimates across the islands mean rainfall can vary from one location to another, it might be raining in one village while conditions remain dry just a short distance away.

This variability is typical of Pacific island climates and adds to the dynamic natural beauty of Wallis and Futuna.

Wallis and Futuna enjoys long daylight hours year-round thanks to its equatorial location.

Around 13 hours of daylight are typical during the wetter months from November to February, while daylight shortens slightly to about 11-12 hours during the mid-year period when the south-east trade winds are more prominent.

Sunshine hours vary with the seasons. The sunniest conditions generally occur between August and October, when the islands receive roughly 5-6 hours of bright sunshine per day on average.

During the wetter months of December and January, cloud cover is more frequent, reducing sunshine hours somewhat, though sunny intervals remain common between tropical showers.

Overall, Wallis and Futuna’s climate provides abundant daylight throughout the year, making it well suited for outdoor exploration and lagoon activities in most seasons.

Wallis and Futuna lies within the South Pacific cyclone belt and can be affected by tropical cyclones during the wetter months from November to April.

The highest likelihood of severe weather generally occurs between December and March, particularly during years influenced by regional climate patterns such as El Niño.

While the overall risk of major cyclones is low to moderate, storms can bring heavy rainfall, strong winds and coastal swells.

Historically, the territory has experienced impacts from tropical cyclones, including flooding, temporary disruptions to infrastructure and storm-related damage. However, such events are relatively infrequent, and local authorities maintain established emergency response systems to manage severe weather situations.
