About Bonto Reef

A reef dive. It goes down to 25 m. You get in from a boat. It suits Open Water divers and up, as a dive guide states it. The coast faces W: swell from the W reaches it, and wind from the E blows out to sea. No dive centre within 50 km on the map: book a liveaboard or a boat from further off. The sea is about 28°C in February, its coldest month (3 mm wetsuit), and 30°C in November, its warmest (rash vest or 1 to 2 mm). For Open Water divers the best months are usually April, May, August and September, with about 7 good days in 7; in January and February, about 5. From the weather of past years. No town nearby. No stay checked for this site yet: Bontoh, 2 km away, is the nearest town we list. Nearest airport: BMU (BMU), 50 km.
