Best Time to Dive in Indonesia
Dive into Indonesia anytime! One of the archipelago’s greatest appeals for divers is its year-round accessibility.
The dry season, between May and September, is ideal for visiting most parts of the archipelago, with the rainy season lasting from October to April. You’ll usually find that March to October is generally the peak season for diving.
Meanwhile, the average water temperature across Indonesia’s dive sites ranges from 26°C to 29°C (82 to 85F).
An exception to this general guideline applies to some dive sites, including those in Raja Ampat, which is best dived during its warmer period from November to April.
Now, let’s splash straight into the fin-tastic spots for diving in Indonesia!
Top 12 Diving Sites in Indonesia
Weh Island
Location: Sumatra
Difficulty: Intermediate to advanced
Pulau We, or Weh Island, is a must-visit among the top Indonesian dive destinations. Perched off the northern edge of Sabang, Aceh Province in Sumatra, this inhabited island hides away in a remote location with strong currents, giving Pulau Weh’s dive spots some amazing glimpses into aquatic life. Discover its underwater volcano, one of the very few safe volcanic dive spots on the planet! Whilst the temperature gently rises at this spot, a chilled vibe remains, with pufferfish often greeting divers among the sulphur bubbles at this jaw-dropping hot spring site. With an average visibility of around 30 metres, Weh explodes with coral reefs, stingrays and large coral reef fish like giant trevallies, parrot fish, angel fish and butterfly fish. The Sophie Rickmer Wreck, a German cargo ship that sank during World War II, is a notable site for tech diving. Weh is a good destination all year-round, although if you’re hoping to have a manta ray encounter, it’s best to go at the end of the year.
How to get to Weh Island’s diving sites?
To begin, fly to Banda Aceh using a local airline, with popular starting points being Kuala Lumpur, Jakarta, or Medan. Once you arrive, head to Ulee Lheue Port and hop on the fast ferry to Weh, taking around an hour. On the island, local taxis or motorbike taxis (ojek) are available for transport.
Menjangan Island
Location: West Bali
Difficulty: Beginner to intermediate
Think you’ve seen all of Bali? Perhaps you just need to head west next time you visit! When it comes to underwater wonders, Menjangan Island in West Bali should definitely be on your radar. The pace here is slower, making it an enjoyable spot for relaxed coral wall dives where you can observe sharks, moray eels, angel fish, nudibranchs and sea turtles up close. Located in a protected marine area, Menjangan’s dive spots are less touristy and offer a rich macro display. It’s also an excellent area for those just getting into diving, thanks to the surrounding gentle currents. However, skilled divers will find Menjangan just as rewarding with its underwater photography opportunities – don’t forget to snap some pics of the underwater temple garden! Scuba diving in Bali combines the unique charm of slow travel, along with the discovery of underrated spots that will certainly make a splash in your heart!
How to get to Menjangan’s diving sites?
To travel to West Bali’s top diving spots, the first step is to fly into Bali’s Ngurah Rai International Airport. If you’re staying in the more touristy areas of South Bali, it will take around 4-hours to reach the Pemuteran region in West Bali – you can drive yourself or join a tour. Next, you will need to take a 30-minute boat ride to Menjangan Island. Please note that visiting the Menjangan National Park requires an entrance fee of IDR 200,000 on weekdays and IDR 300,000 on weekends/public holidays.
Tulamben
Location: North Bali
Difficulty: Beginner to intermediate
This quaint Bali fishing village is iconic for its vast marine life and local traditions, making your visit truly magical. It’s come a long way from its rustic beginnings, and you can now find heaps of comfy oceanfront resorts, making Tulamben a top-tier scuba diving paradise. You can easily dive to the USAT Liberty wreck, a site of great historical significance, thanks to a 1942 volcanic eruption bringing the vessel to just off Tulamben’s shores. Typical magical underwater encounters include turtles and bumphead parrotfish, as well as tiny creatures darting beneath the corals, like ghost pipefish and nudibranchs. If you’re a keen photographer, early morning and sunset dives offer plenty of snappy-happy opportunities, set against the majestic backdrop of Mount Agung.
How to get to Tulamben’s diving sites?
It’s easy to reach Tulamben by car, especially from the south of Bali. Hiring a driver for the day gives you total flexibility, or another easy option is using ride-hailing apps like Grab. If you’re travelling straight from the Ngurah Rai International Airport or from Denpasar, the travel time takes about 3-hours.

Crystal Bay, Nusa Penida
Location: Nusa Penida Island, Bali
Difficulty: Intermediate to advanced
As its name suggests, Crystal Bay, one of the most popular Nusa Penida dive sites, features clear waters that often give divers visibility down to an impressive 30 metres. Lose yourself in the underwater beauty of diverse coral plateaus and slopes, making this site perfect for spotting larger marine mammals. Crystal Bay is also known for the peculiar-looking Mola Mola, which can be spied during deeper early morning dives at certain times of the year. What’s more, you can expect to see reef sharks, turtles, various reef critters, and manta rays as you explore the crystal-clear waters. Whilst the outer edges of the bay can have strong currents, the inner areas offer a safe playground for intermediate divers. You can dive in Nusa Penida any time of the year, but if you want to glimpse Mola Mola, then a visit between June and October might be your best bet.
How to get to Crystal Bay’s diving sites?
This underwater paradise in Nusa Penida is just a breezy boat ride from Sanur on mainland Bali. Head to Sanur Harbour by car, taxi, or Grab to take a 45-minute speedboat ride to Nusa Penida (ticket price usually varies between IDR 280,000 and IDR 540,000). You can get around Nusa Penida by hiring a scooter, however due to the island’s uneven roads, we would only recommend doing this if you already have scooter riding experience. Hiring a private car with a driver is the most hassle-free way to safely enjoy your diving trip there.
