Located a little more than 10 degrees below the equator in the western Indian Ocean the islands have a maritime tropical climate with wet and dry seasons. The wet season is from October to April. During this time, northerly winds bring moist, warm air from the Indian Ocean to the islands. Heaviest rainfall occurs during December to April and amounts can reach as high as 390 mm (15 inches) in a month. The mean temperature during the wet season is approximately 25 degrees celsius (77° F). The hottest month is March with temperatures averaging around 30 degrees celsius (86° F). From May to September southerly winds dominate the region. These are cooler and drier and temperatures in the islands average around 19° C (66° F).
Rainfall and temperature vary from island to island during any month. They also vary from place to place on an island primarily due to the topography. The central, higher areas of an island are often cooler and more moist than the coastal regions and the windward side of an island will receive more rainfall than the leeward side. The variations in temperature and rainfall result in microecological differences on the islands with distinct regions of flora and fauna.
