About Rollercoaster
A reef dive. It goes down to 30 m. You get in from a boat. It suits experienced divers only, as a dive guide states it. The coast faces N: swell from the N reaches it, and wind from the S 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 29°C in January, its warmest (rash vest or 1 to 2 mm). For experienced divers the best months are usually January, February, March and April, with about 7 good days in 7. From the weather of past years. No town nearby. No stay checked for this site yet: Bontoh, 35 km away, is the nearest town we list. Nearest airport: BMU (BMU), 67 km. Within 5 km we also list 1 dive site.

Day scores are the conditions out of 80, from the two best daylight readings: a morning and an afternoon dive. Sea is the open water's waves near the site, in metres, halved for a sheltered site. Wind and gusts are in knots (10 kn is about 19 km/h); "boats in" marks gusts that keep dive boats in. This week's visibility, the current and the life no free forecast gives.
