Wallis and Futuna is located about two-thirds of the way from Hawaii to New Zealand. It is 13°18′S 176°12′W Coordinates: 13°18′S 176°12′W, 360 km (220 mi) west of Samoa and 480 km (300 mi) northeast of Fiji.

The territory includes the island of Uvéa (also called Wallis), which is the most populous; the island of Futuna; the virtually uninhabited island of Alofi; and 20 uninhabited islets. The total area of the territory is 274 square kilometres (106 sq mi), with 129 kilometres (80 mi) of coastline. The highest point in the territory is Mont Puke, on the island of Futuna, at 524 metres (1,719 ft).

The islands have a hot, rainy season from November to April, when tropical cyclones passing over them cause storms. Then they have a cool, dry season from May to October, caused by the southeast trade winds that predominate during those months. The average annual rainfall is between 2,500 and 3,000 millimetres (98–118  in), and rain is likely on at least 260 days per year. The average humidity is 80%. The average annual temperature is 26.6 °C (79.9 °F), rarely falling below 24.0 °C (75.2 °F); during the rainy season, it ranges between 28.0 °C (82.4 °F) and 32.0 °C (89.6 °F).

Only 5% of the islands' land area consists of arable land; permanent crops cover another 20%. Deforestation is a serious problem: Only small portions of the original forests remain, largely because the inhabitants use wood as their main fuel source, and, as a result, the mountainous terrain of Futuna is particularly susceptible to erosion. The island of Alofi lacks natural freshwater resources, so it has no permanent settlements.

Volcanic activity during the mid-Pleistocene created numerous volcanic crater lakes on Uvea (Wallis Island). The names of some of them are: Lalolalo, Lano, Lanutavake, Lanutuli, Lanumaha, Kikila, and Alofivai.

Wallis and Futuna is part of the Fiji tropical moist forests terrestrial ecoregion.
