Palmyra Atoll

Palmyra Atoll, is an incorporated atoll administered by the United States government. The atoll is 4.6 square miles (12 km²), and it is located in the Northern Pacific Ocean at 5°53′N, 162°5′W. Geographically, Palmyra is one of the Northern Line Islands (southeast of Kingman Reef and north of Kiribati Line Islands), located almost due south of the Hawaiian Islands, roughly halfway between Hawaii and American Samoa. Its 9 miles (14.5 km) of coastline has one anchorage known as West Lagoon. It consists of an extensive reef, two shallow lagoons, and some 50 sand and reef-rock islets and bars covered with vegetation—mostly coconut trees, Scaevola, and tall Pisonia trees.

The islets of the atoll are all connected, except Sand Island in the West and Barren Island in the East. The largest island is Cooper Island in the North, followed by Kaula Island in the South. The northern arch of islets is formed by Strawn Island, Cooper Island, Aviation Island, Quail Island, Whippoorwill Island, followed in the East by Eastern Island, Papala Island, and Pelican Island, and in the South by Bird Island, Holei Island, Engineer Island, Tananger Island, Marine Island, Kaula Island, Paradise Island and Home Island (clockwise). Average annual rainfall is approximately 175 inches (4,445 mm) per year. Daytime temperatures average 85°F (29°C) year round.
