Climate and monthly weather forecast
Wallis and Futuna

Wallis and Futuna, a French island collectivity situated in the South Pacific, consists of two main islands and a number of smaller islets. Being located in the tropical region, it is dominated by the oceanic influences which bestow a tropical rainforest climate upon the country. The islands are just south of the Equator, causing year-round high temperatures and heavy precipitation.

The Af or tropical rainforest climate, as characterized by the Köppen climate classification, ensures that there is no dry season throughout the year. Temperatures usually do not dip below 18°C (64.4°F) even during the coolest months. Precipitation is uniformly distributed over the year, with annual rainfall often exceeding 2500mm (98.43"). The humidity is perpetually high, and the country is occasionally subjected to tropical cyclones.

Given the stable year-round high temperatures and constant rainfall, there is not a majorly distinct "best" time to visit Wallis and Futuna. However, the relatively drier period from June to October might provide a slightly more comfortable visit. During this time, temperatures range from 24°C (75.2°F) to 28°C (82.4°F), with slightly lower humidity compared to other times of the year. It should be noted that even during this period, the weather can be unpredictable with potential rain showers.

The period from November to April is typically the wettest, making it less ideal for visits. This is also the period when Wallis and Futuna is most susceptible to tropical cyclones which can bring extreme rainfall and high wind speeds. The temperature during this time fluctuates between 26°C (78.8°F) to 30°C (86°F), and the high humidity can make the heat feel more oppressive. Travellers who prefer less rain and lower humidity should avoid these months.

Given Wallis and Futuna’s tropical rainforest climate, traditional spring weather as understood in temperate regions does not apply here. However, during the period of September to November, which can be considered a relative equivalent, the rainfall starts to increase. Temperatures hover around a high of 29°C (84.2°F) and a low of 24°C (75.2°F). Despite the increase in rainfall, these months are still considered part of the slightly drier period of the year.

The period from December to February represents the height of the wet season in Wallis and Futuna. Rainfall is at its peak during these months, often exceeding 300mm (11.81") per month. The temperatures are also at their highest, fluctuating between 26°C (78.8°F) to 30°C (86°F). Due to its tropical location, daylight hours remain relatively constant, with about 13 hours of daylight each day.

Again, the concept of autumn does not traditionally apply to Wallis and Futuna due to its tropical rainforest climate. However, for the months of March to May, representing an equivalent period, the country continues to experience high temperatures between 26°C (78.8°F) to 29°C (84.2°F). Rainfall remains high but begins to taper off as the months progress. This period can still be quite humid and wet, although not as much as the peak of the wet season.

In Wallis and Futuna, the months of June to August can be thought of as the relative equivalent to winter, although it remains warm. This is the driest period of the year, though rainfall is still considerable compared to many other countries. Temperatures range from a comfortable 24°C (75.2°F) to 28°C (82.4°F). Even in this relatively drier period, the country experiences an average of 15 to 18 rainy days per month, showing the pervasive influence of the tropical rainforest climate.
