Scuba Diving the Raja Ampat Islands

It’s hard to find a scuba diving magazine that doesn’t feature or extol the virtues of Raja Ampat diving. Raja Ampat is on the bucket list of seasoned divers from around the world – and for good reasons. This unique region has the highest known concentration and diversity of marine life on earth.

This is a region where whale sharks breed, manta rays dance, sperm whale migratory routes pass through, turtles lay eggs on the pristine white sand beaches, and jewel-like tropical fish glimmer beneath the surface. It’s hard not to be mesmerized by the sheer abundance of fish and the incredible marine biodiversity that is on display at every dive site.

Raja Ampat diving showcases numerous species of sharks and rays in addition to the whale sharks and mantas. Other species commonly spotted here include wobbegong sharks, black and white tip reef sharks, epaulette sharks, eagle rays, and huge marble rays. It’s not only the sharks and rays that impress, the reefs are adorned with tiny jewel-like reef fish, dense schools of silvery fish occupy the blue, and for those who prefer macro life, there is no shortage of intriguing critters such as pygmy seahorses, colorful nudibranch, harlequin and emperor shrimps, flamboyant cuttlefish, flasher wrasses, frogfish and everything in between.

For many divers, Raja Ampat is the final frontier of diving. Located in the East Indonesia/West Papua region of the coral triangle, Raja Ampat is also a top global priority for marine conservationists.

Beautiful sunset ocean for raja Ampat diving.When is the Best Time to Dive the Raja Ampat Islands?

Here at el Aleph, we are frequently asked when the best time to dive the Raja Ampat Islands is during the calendar year. One of the beauties of this region is that it is a year-round destination, however, there are marine life seasons so it may depend on what you are hoping to see.

One constant is the water temperature, which remains at a consistent 28°C-30°C throughout the year.


Indonesia’s weather patterns ensure that no matter what time of year you choose to enjoy Raja Ampat diving, you’ll experience tropical temperatures. For your comfort, all of el Aleph’s cabins are air-conditioned to guarantee a comfortable night’s sleep. Being out on deck also means enjoying the cooling sea and cruising breezes.

Indonesia has an equatorial climate which generally means a wet and dry season. However, in Raja Ampat, there are also very specific micro-climates that vary according to the proximity of an area to land masses and their elevation. We usually enjoy bright sunny days with occasional tropical rainfall showers consistently throughout the year.


For Raja Ampat diving, the season is generally considered to run from September through to the beginning of April as this is when the manta rays are present at the cleaning stations and enjoying the plankton-rich waters. However, the high levels of plankton can affect visibility. For the very calmest waters and best visibility, visit during the main diving season which is between November and March.


The summer months in Raja Ampat are windier, which can make the sea choppy on the surface, it does not interfere with diving. Cruising is rarely affected due to El Aleph’s unmatched stability and highest level of specifications to ensure the comfort you would expect when enjoying a luxury cruise.

Our experienced crew are experts at navigating the Raja Ampat Islands to provide you with the best possible cruising conditions – at any time of year.
