The climate is 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.
