The nation of Solomon Islands consists of an extensive archipelago: Choiseul, the Shortland Islands, the New Georgia Islands, Santa Isabel, the Russell Islands, the Florida Islands, Malaita, Guadalcanal, Sikaiana, Maramasike, Ulawa, Uki, Makira (San Cristobal), Santa Ana, Rennell, Bellona and the Santa Cruz Islands.

The distance between the most western and most eastern islands is about 1,500 km (930 mi). Especially the Santa Cruz Islands, north of Vanuatu, (of which Tikopia is part) are isolated at more than 200 km (120 mi) from the other islands. The total land size is 28,896 km2 (11,157 sq mi). It has the 22nd largest Exclusive Economic Zone of 1,589,477 km2 (613,701 sq mi).

Bougainville is geographically part of the Solomon Islands archipelago, but politically an autonomous region of Papua New Guinea.

Geology and ecologyEdit

Volcanoes with varying degrees of activity are situated on some of the larger islands, while many of the smaller islands are simply tiny atolls covered in sand and palm trees.


The climate is tropical, though temperatures are rarely extreme due to cooling winds blowing off the surrounding seas. Daytime temperatures are normally 25 to 32 °C (77 to 90 °F), falling to about 13 to 15 °C (55 to 59 °F) at night. From April to October (the dry season), the southeast trade winds blow, gusting at times up to 30 knots (55 km/h) or more.

November to March is the wet season—the northwest monsoon—typically warmer and wetter. Cyclones arise in the Coral Sea and the area of the Solomon Islands, but they usually veer toward Vanuatu and New Caledonia or down the coast of Australia.
