Comoros Geography: The Comoros archipelago consists of four main islands aligned along a northwest-southeast axis at the north end of the Mozambique Channel, between Mozambique and the island of Madagascar. Still widely known by their French names, the islands officially have been called by their Swahili names by the Comoran government. They are Njazidja (Grande Comore), Mwali (Mohéli), Nzwani (Anjouan), and Mahoré (Mayotte). The islands' distance from each other--Njazidja is some 200 kilometers from Mahoré, forty kilometers from Mwali, and eighty kilometers from Nzwani--along with a lack of good harbor facilities, make transportation and communication difficult. The islands have a total land area of 2,236 square kilometers (including Mahoré), and claim territorial waters of 320 kilometers.
Comoros Climatet: Marine tropical, with two seasons: hot and humid from November to April, the result of the northeastern monsoon, and a cooler, drier season the rest of the year. Average monthly temperatures range from 23° C to 28° C along the coasts. Although the average annual precipitation is 2,000 millimeters, water is a scarce commodity in many parts of Comoros. Mwali and Mahoré possess streams and other natural sources of water, but Njazidja and Nzwani, whose mountainous landscapes retain water poorly, are almost devoid of naturally occurring running water. Cyclones, occurring during the hot and wet season, can cause extensive damage, especially in coastal areas. On the average, at least twice each decade houses, farms, and harbor facilities are devastated by these great storms.
