Bali is in the Coral Triangle, which is the most biodiverse maritime area in the world. It has over 76% of the world's coral species and more than 2,000 reef fish species. Because of this, scuba diving in Bali is an amazing experience. You can do anything from dramatic wreck diving and muck diving to seeing manta rays and the rare Mola mola.
This article talks about Bali's six main diving areas: Nusa Penida, Tulamben, Amed, Padang Bai, Menjangan Island, and the Gili Islands, all as the best places to scuba dive in Bali. It goes into detail on the best dive sites, the certifications you need, the best times of year to dive, and what kinds of marine life you can expect to see. The information is useful for qualified divers of all levels, from Open Water to advanced, who are planning a dive vacation to Indonesia.
Nusa Penida is the best place to scuba dive in Bali because you can see manta rays and Mola mola. Tulamben is great for shore diving and the famous Liberty Wreck. Amed is great for relaxing reef diving and macro creatures. Padang Bai has a wide range of sites, from novice bays to shark point dives. Menjangan Island and the Gili Islands are great places to go if you want to view coral walls that are still in good shape or waters full of turtles. They are also great for divers who have already been to Bali and want to try something different.

Understanding The Dive Sites in Bali
There are different areas for diving in Bali, and each one has its own distinctive underwater environment. And this is what scuba divers visiting Bali need to know.
The northeast coast of Tulamben and Amed is volcanic and has black sand slopes, easy shore diving, and calm waters. The limestone landscape in the southeast islands of Nusa Penida and Nusa Lembongan is very spectacular, with strong currents and big fish encounters. The east coast of Padang Bai has a combination of calm coves and fast-moving channels. Menjangan Island in the northwest is protected by West Bali National Park and has beautiful coral cliffs.
On Bali's northern and eastern coasts, water temperatures usually stay between 27 and 30 degrees Celsius. However, places affected by deep-water upwellings, like around Nusa Penida, can drop to 18 to 24 degrees Celsius during the dry season. At muck diving areas, visibility ranges from 10 to 15 meters, while at iconic sites like Crystal Bay, it ranges from 30 to 40 meters.
Diving Conditions and Seasonality
From April to November, the dry season has the best diving conditions in all dive sites in Bali. The seas are usually calmer, visibility is better, and dive operators can get to more spots more easily. This time of year is also Mola mola season at Nusa Penida, when chilly upwellings attract these oceanic sunfish to cleaning stations. The peak season is usually from July to September.
The wet season, which lasts from December to March, brings more rain, possible runoff that makes it harder to see near shore, and sometimes rougher seas. But the northeast coast locations at Tulamben and Amed are frequently still very diveable even during the monsoon months, so they are good backup alternatives.
Water temperature expectations by region:
- Tulamben and Amed: 27–30°C year-round
- Padang Bai: 26–29°C, colder during Mola season July - October
- Nusa Penida: 26–28°C surface, dropping to 18–24°C at depth during Mola mola season
- Menjangan: 27–30°C year-round
Experience Level Categories
To standardize site recommendations throughout this guide, the following experience categories apply for Bali scuba diving:
Beginner sites (Open Water certified, 5–20 logged dives): Calm conditions, depths within 18 meters, minimal current. Suitable for recently certified scuba divers and those building confidence.
Intermediate sites (Advanced Open Water, 25–50 logged dives): Moderate currents, depths to 30 meters, requires good buoyancy control and some drift dive experience.
Advanced sites (Deep/Drift specialties, 50+ logged dives): Strong currents, potential downcurrents, depths beyond 30 meters. Requires excellent buoyancy, current management skills, and comfort with challenging conditions.
Nusa Penida: Manta Rays and Mola Mola Capital
Nusa Penida is the best scuba diving in Bali to see huge animals up close. This big island and its neighbors Nusa Lembongan and Nusa Ceningan are south of the mainland and across deep canals. Scuba divers come here to witness manta rays, Mola mola, reef sharks, and big pelagic fish.
The underwater environment here is very different from Bali's other dive spots. The canals are full of strong tidal currents, and cold upwellings deliver nutrient-rich water from the depths. The complicated terrain makes walls, slopes, and cleaning stations. These conditions make it quite easy to see things, typically up to 25–40 meters away, and they bring in the marine species that makes this location famous among expert divers.
General conditions:
- Water temperature: 26–28°C surface, 18–24°C at depth during upwelling season
- Visibility: 15–40 meters depending on site and conditions

Seasonal Diving and Marine Life Calendar
If you know how Bali's seasons work, you can arrange your vacation to see certain marine life and have the best diving conditions.
Optimal Diving Seasons by Location
| Location | Peak Season | Off-Season Notes |
|---|---|---|
| Nusa Penida | April–November; Mola mola July–October | Rougher seas June–August at Manta Point |
| Tulamben | Year-round | Reliable even during wet season |
| Amed | Year-round; April–November optimal | Slightly reduced visibility December–March |
| Padang Bai | April–November | Some sites affected by monsoon swell |
| Menjangan | April–November optimal | Diveable year-round; boat access best in dry season |
| Gili Islands | April–November | Year-round diving possible |
Dry Season (April–November): Conditions that are the same in all areas most of the time. The seas are calmer, the visibility is better, and getting to the spot is easier. During the peak tourist months of July and August, rates go up and diving spots get crowded.
Wet Season (December–March): More rain and possibly less visibility along the shore. The northeast shore sites (Tulamben, Amed) are still very good. Fewer visitors and lower prices.
No matter what time of year it is, Bali scuba diving is a one-of-a-kind spot in the globe because diving is good all year. Rain isn't always there, even during the wet season. Just because the weather is poor for weeks or months doesn't indicate it will be bad every day.
Marine Life Seasonal Patterns
Mola mola (Oceanic Sunfish):
- Peak sightings: July–October at Crystal Bay (Nusa Penida) and offshore Padang Bai sites
- Trigger: Cold upwellings dropping water temperature to 18–24°C
- Best visibility: 30–40 meters during upwelling events
Manta Rays:
- Year-round presence at Nusa Penida cleaning stations
- Access limitations: Manta Point may be inaccessible during heavy swell, particularly June–August
- Best conditions: Calm days with plankton-rich water
Bumphead Parrotfish:
- Reliable sightings: Liberty Wreck at sunrise, year-round
- Best timing: Early morning dives before 7 AM
Reef Sharks:
- Year-round: White tip sharks at Shark Point (Padang Bai), reef sharks at Menjangan
- Conditions: Better visibility in dry season improves encounter quality
Common Diving Challenges and Solutions
Dive sites in Bali are diverse, each with its own set of problems that proper preparation might help with.
Strong Current Management
Around Nusa Penida, Tepekong, and Blue Corner, there are currents that can easily sweep away divers who aren't ready. Inexperienced divers have had problems at Crystal Bay because to downcurrents.
Solutions:
- Complete Drift Diver specialty certification before attempting current-exposed sites
- Follow dive guide briefings precisely regarding entry points and abort procedures
- Carry appropriate equipment: reef hooks (where permitted), surface marker buoys, audible signaling devices
- Monitor tide tables and discuss current predictions with dive operators
- Maintain conservative depth limits when currents are running
Seasonal Visibility Variations
Rainfall during the wet season causes runoff that makes it harder to see nearshore, especially in the south and west.
Solutions:
- Focus wet season diving on northeast coast sites (Tulamben, Amed) less affected by runoff
- Choose offshore sites like Menjangan where water clarity remains more stable
- Schedule flexibility allows waiting for conditions to improve
- Morning dives often offer better visibility before wind and weather develop
Experience Level Mismatches
Many scuba divers underestimate the advanced dive sites in Bali, particularly around Nusa Penida where conditions change rapidly.
Solutions:
- Honest self-assessment of current experience and recent dive activity
- Start with easier sites (Tulamben, Padang bai) before progressing to challenging locations
- Complete appropriate specialty training (Deep, Drift, Nitrox) before attempting advanced sites
- Work with reputable dive operators such as haha, who enforce experience requirements
- Build skills progressively across multiple diving days rather than rushing to signature sites
Cold Water at Depth
Thermoclines at Nusa Penida can decrease temperatures from 28°C to below 20°C in just a few seconds. This can cause thermal shock and make air consumption go up. This is something that needs to be thought about. We also suggest that you dive in Nusa Penida from June to October while wearing a 5mm wetsuit, a sweatshirt, and gloves.
Solutions:
- Wear appropriate exposure protection: 5mm full wetsuit minimum, 7mm or hooded vest for Mola mola dives
- Carry backup thermal protection for unexpected temperature drops
- Monitor air consumption closely during cold water exposure
- Plan shorter bottom times when diving deep cold water

It is perfect for experienced divers who wish to see all of Indonesia's aquatic life.
These itineraries are made to fit different skill levels and interests, so every scuba diver who goes to Bali may customize their trip to their liking while still having access to some of the best diving in the world.
Conclusion and Trip Planning Next Steps
Bali has some of the best diving in the world in a wide range of habitats, all in a small region. Nusa Penida has exciting big-animal encounters for experienced divers, while Tulamben's Liberty Wreck is great for beginners because they can dive from the shore. Amed is a laid-back community with great macro chances, and Padang Bai is easy to get to and has a lot of different sites. Menjangan and the Gili Islands give people more choices if they want to view beautiful walls or turtles for sure.
Immediate planning steps:
- Assess your current certification level and logged dive count against site requirements
- Identify your primary diving goals (big animals, wrecks, macro, relaxed reef diving)
- Select your primary region based on experience level and interests
- Plan arrival timing around seasonal marine life priorities (Mola mola season if applicable)
- Book accommodations near your chosen diving area—proximity reduces transfer time and maximizes diving days
