Geology and Climate
The archipelago consists predominantly of pre-Tertiary continental islands primarily of quartzites and shales covered by basaltic lava. Geologically, the islands are part of Sundaland. The islands have extensive fringing and patchy reefs coral reefs.
The best time to visit the islands is during the dry season, generally from April to October. The islands are influenced by the northwest monsoon during which winds from the west-northwest predominate and ocean currents are in an easterly direction. During the monsoon, rainfall averages 40 mm/day. During the southeast monsoon, dry winds from the east-southeast predominate and the ocean currents are in a westerly direction bringing water masses from the Flores Sea. Upwelled water masses during the southeast monsoon from the Flores and Banda Seas provides lower sea surface temperatures than during the northeast monsoon. The shallow slopes (5° to 15°) of the island shelves in the Java Sea (which rarely exceeds a depth of 55 m), provide environments for extensive reef development.

Famous quotes containing the word climate:
“The question of place and climate is most closely related to the question of nutrition. Nobody is free to live everywhere; and whoever has to solve great problems that challenge all his strength actually has a very restricted choice in this matter. The influence of climate on our metabolism, its retardation, its acceleration, goes so far that a mistaken choice of place and climate can not only estrange a man from his task but can actually keep it from him: he never gets to see it.”
—Friedrich Nietzsche (1844–1900)
