Geography, Weather, & Wildlife of Nauru


The nation of Nauru consists of only one island, the island of Nauru, which sits in the Pacific Ocean between Micronesia and Melanesia. The island is very small and made of coralline. The entire island is little more than a coral reef, which doesn't raise much above sea level; the highest point on Nauru is only 200 feet (60 meters) above sea level.

There is little rain on Nauru and due to the coral base, the soil is poor. There are no rivers or lakes on the island and little to no fresh water exists. The island is also surrounded by coral reefs.

Nauru sits directly on the equatorial ocean current that runs almost directly from east to west. It was with the ocean currents that people first arrived to Nauru and have stayed, despite the difficult soil and geological conditions. However, these ocean currents aren't enough to attract regular visitors so over time the people on Nauru became almost completely isolated and developed a unique culture.


Nauru's weather is hot, humid, rainy, and fairly predictable and consistent. This climate makes the weather ideal for crop growth and human settlement, although the island's soils are poor. At the very least these rains provide fresh water for the people.

There are two basic seasons in Nauru: the dry season, which runs from about November to January and the wet season, which runs from about May to October. Since temperatures are fairly constant year round, the real difference in seasons is rainfall, which is also fairly negligible. Year round, daily lows average about 77° F (25° C), while daily highs average 88° F (31° C).

During the dry season months of November to January there is almost no rain. The shoulder seasons, including the months of February, March, April, September, and October, still average less than 2 inches (40 mm) per month.

The humidity tends to rise from about May to August and the rains slightly increase. However, these months still average less than 2 inches (40 mm) per month, other than July, which spikes with average rainfall of 3 inches (75 mm) that month. The months of about December to April are also cyclone season in the South Pacific, but Nauru is not in the cyclone zone.


As an island nation the number of native plants and animals on Nauru are severely limited. The native land life is nearly non-existent and the native plant life was also very limited; only the migrating birds and sea life had any significant presence in historic Nauru. Most of what is found on the island today was introduced in pre-historic times by the migrating people, birds, winds, and ocean currents.

As an island nation that rose from the sea floor there were no native mammals in Nauru, although a few bat species arrived thousands of years ago. Other than this, no land mammals existed on Nauru until the arrival of the earliest people, who likely came from the region of New Guinea and brought with them pigs, dogs, mice, and rats by the 1200s, if not earlier.

The other historic mammals connected with Nauru are in the sea as dolphins and whales are present in the waters surrounding the island. These waters are also filled with thousands of fish, shellfish, and other forms of sea life. In these waters you can find surgeonfish, clownfish, sailfish, puffer fish, butterfly fish, grouper, barracuda, tuna, bonito, mackerel, marlin, mahi-mahi, shrimp, krill, crab, seahorses, manta rays, sharks, jellyfish, starfish, and sea urchins among many others.

The water and the land have attracted more than just fish though, they have also attracted numerous birds, including many that feed off the animals in the sea. The bird life in Nauru includes doves, scrub fowls, terns, frigate birds, and heron among others.

Like the mammalian life, the reptilian and amphibious life is fairly limited. The most common of these animals are those adapted to the water and swimming as sea turtles can be found in the nearby waters. Land species have again made their way to the islands in numerous methods and today lizards are among the most common of these animals.

The insect and other small animal life is fairly diverse as many insects can fly or float and have made their way to Nauru. These animals include butterflies, ants, flies, and spiders among others.

Like the animal life, which is limited due to the geography of Nauru, the plant life is also very limited. It is doubtful any plants originated in the country itself other than a very limited number of local varieties. However the winds and water currents have taken seeds to the island and in other cases birds have transported seeds to the island. Because of this many of the most common plants on the island today are native to the nearby islands of New Guinea and those further west. Plants from these nearby islands that now thrive in the country include coconuts, taro, breadfruit, bananas, yams, arrowroot, lemons, and sugarcane among others.

There is also a substantial presence of other trees and plants, including orchids, hibiscus, eucalyptus, frangipani, ferns, mosses, tamanu trees, mangrove trees, and pandanus trees.
