Dili Bay and the North Coast sit along the Ombai Strait, where nutrient-rich upwellings from deep-water channels feed a varied mix of fringing reefs, walls, drop-offs, muck sites, and an artificial reef. The area spans sites from Maubara Town in the west to the bay itself, with shore entry the dominant access method. Water stays warm year-round, and the dry season from April to November brings the calmest conditions and best visibility. The site roster suits beginners and intermediate divers, with species ranging from dwarf pipehorse, painted frogfish, and seamoth to coral grouper and cleaner shrimp.
