Your Guide to Diving in Ambon

Critter Heaven Scuba Adventure

...Highlights: great macro life/ marine diversity...
...Diving environment: advanced and beginner divers, off the beaten track...

Dutch Ichthyologist Peter Bleaker was probably the first to demonstrate that the diving in Ambon would be something very special when in 1863 he discovered 783 species of fish, just in Ambon Bay alone.

You can put this achievement into some kind of perspective when one compares that number with, for example, the less than 700 in the whole of Thailand. His technique of cataloguing fish species at that time was to catch them with a small net; if only he'd had scuba equipment or a liveaboard dive boat!

The bay of Ambon is 563 metres deep and 8 kilometres wide at its mouth, and cuts 23 kilometres back into the island. Modern history of the last century witnessed the battle of Ambon in 1942 between Japan and the Allied Forces. Since that event, the local people used coral to rebuild roads thus destroying the fringing reefs, and later dredged the bay's shallows to allow bigger ships, so what is left in the bay now is just some world class muck diving.

The eponymous Ambon scorpionfish is one of the rare creatures that divers find here with some frequency. This incredible critter comes in shades of pink, green, brown yellow or red, with variable skin flaps and filaments; but is characterised by its very long growths above each eye.

Also a rare find anywhere are Halimeda ghostpipefish. This cryptic creature has green-grey rounded fin lobes resembling leaf-like segments of Halimeda algae, where they shelter in pairs or solitarily. To spot this one, look closely at anything that resembles a twig!

Elsewhere along the outer coastline of the horseshoe shaped island of Ambon, you'll find some colourful soft coral wall diving, with many overhangs and several caves to explore. There are plenty of the reef fish here that are synonymous with Indonesia and the sites are a pleasant break from the muck dives of the bay.

How to Dive Ambon

Although there are some dive resorts on Ambon, we recommend you join a Banda Sea liveaboard trip. That way you can enjoy diving the Ambon region together with the amazing Banda Islands.

Set in splendid isolation in the heart of the Banda Sea, the Bandas are blessed with reefs bursting with life. Pelagics, huge schools of fish, and macro diversity are the main drawcards, including dogtooth tuna and mobula rays. At many sites you'll see enormous schools of fusiliers and thousands of redtooth tirggerfish. At the other end of the scale, there are native mandarinfish and Ambon scorpionfish.

The Diving Season

Dive conditions in Ambon are good all year round but our Banda liveaboards season runs only in the months of February to April and during the September to November period. The island is more sheltered than other areas of the Banda Sea and can therefore be dived all year round.

Visibility is variable around Ambon and seldom exceeds 20m. At some of the muck dive sites it can be very low but, when the subjects you are viewing are only a few centimetres in front of your mask, that shouldn't be a problem.

During the dry season of October to April there is less rain and the likelihood of better visibility. During the wet season of May to September the area can experience heavy rainfall and even typhoons, although it is unlikely you will experience them if you visit during the times the Indonesian liveaboards visit there. Visit the Weather & Climate website for more details on the climate of Ambon City.
