Geography of the Solomon Islands
The Solomon Islands form an archipelago in the Southwest Pacific about 1,900 kilometers (1,200 mi.) northeast of Australia. With terrain ranging from ruggedly mountainous islands to low-lying coral atolls, the Solomons stretch in a 1,450-kilometer (900 mi.) chain southeast from Papua New Guinea across the Coral Sea to Vanuatu.
The main islands of Choiseul, New Georgia, Santa Isabel, Guadalcanal, Malaita, and Makira have rainforested mountain ranges of mainly volcanic origin, deep narrow valleys, and coastal belts lined with coconut palms and ringed by reefs. The smaller islands are atolls and raised coral reefs, often spectacularly beautiful. The Solomon Islands region is geologically active, and earth tremors are frequent.
The islands' ocean-equatorial climate is extremely humid throughout the year, with a mean temperature of 27° C (80° F) and few extremes of temperature or weather. June through August is the cooler period. Though seasons are not pronounced, the northwesterly winds of November through April bring more frequent rainfall and occasional squalls or cyclones. The annual rainfall is about 305 centimeters (120 in.).
More than 90% of the islands is forested. The coastal strips are sheltered by mangrove and coconut trees. Luxuriant rainforest covers the interiors of the large islands. Soil quality ranges from extremely rich volcanic to relatively infertile limestone. More than 230 varieties of orchids and other tropical flowers brighten the landscape.
