The Andaman Islands offer one of the world’s most pristine and biodiverse underwater environments, making it a premier destination for liveaboard diving enthusiasts. Situated in the Bay of Bengal, these remote islands feature crystal-clear waters, vibrant coral reefs, and an astonishing variety of marine life that can only be fully explored through a dedicated liveaboard expedition. Whether you’re an experienced diver seeking new underwater frontiers or an adventure traveler looking to discover the extraordinary marine ecosystem of the Andamans, this comprehensive guide will help you plan the ultimate liveaboard diving adventure.
Why Choose the Andaman Islands for Liveaboard Diving
The Andaman Islands stand out as a world-class liveaboard diving destination for several compelling reasons. Unlike more commercialized diving locations, the Andamans remain relatively untouched, offering an authentic underwater experience away from crowds. The archipelago’s remote location has preserved its marine ecosystem, resulting in exceptional biodiversity and healthy coral reefs that thrive in these nutrient-rich waters.
Unparalleled Marine Biodiversity
The Andaman Sea hosts over 560 varieties of coral and 1,200 fish species, creating one of the richest marine ecosystems on the planet. The convergence of the Bay of Bengal and the Andaman Sea creates unique conditions that support an extraordinary range of marine life, from tiny macro creatures to large pelagics.
Exclusive Access to Remote Sites
Many of the best dive sites around the Andaman Islands are only accessible via liveaboard vessels. These remote locations offer pristine diving conditions, with visibility often exceeding 30 meters and the opportunity to explore untouched reefs and underwater formations without other divers in sight.
“The Andaman Islands offer some of the most diverse diving I’ve experienced in 20 years of exploration. The combination of healthy reefs, abundant marine life, and minimal diving traffic makes it a true underwater paradise.”

Best Time for Andaman Islands Liveaboard Diving
The Andaman Islands have a tropical climate with distinct seasons that affect diving conditions. Understanding these seasonal variations will help you plan your liveaboard trip for optimal experiences:
| Season | Months | Water Temp | Visibility | Marine Life Highlights | Conditions |
| Peak Season | December – April | 26-29°C (79-84°F) | 20-40m (65-130ft) | Manta rays, whale sharks, eagle rays | Calm seas, minimal rainfall |
| Shoulder Season | October – November, May | 25-28°C (77-82°F) | 15-30m (50-100ft) | Reef sharks, schooling fish | Variable, occasional rain |
| Monsoon | June – September | 24-27°C (75-81°F) | 5-15m (15-50ft) | Macro life, crustaceans | Rough seas, heavy rainfall |
Most liveaboard operators run trips only during the peak and shoulder seasons (October to May), as monsoon conditions make diving challenging and many areas inaccessible. For the best combination of calm seas, excellent visibility, and marine life encounters, the period from January to March is often considered ideal.
Pro Tip: Book your Andaman Islands liveaboard trip at least 6-8 months in advance for peak season (December-April), as berths fill quickly during this popular period.

Essential Preparation Tips
Proper preparation is key to enjoying your Andaman Islands liveaboard experience to the fullest. Here are essential tips to help you prepare for your underwater adventure:
Certification & Experience Requirements
Most Andaman liveaboards require at least an Open Water certification with 20-30 logged dives. However, for maximum enjoyment, an Advanced Open Water certification is recommended as many premier sites feature depths of 18-30 meters and occasionally challenging conditions.
Important: Some operators require certification to 30 meters depth. If you don’t have this, consider taking an Adventure Deep Dive or Advanced Open Water course before or during your trip.
Essential Gear to Bring
- 3-5mm wetsuit (water temperatures range from 25-29°C)
- Dive computer (mandatory on most liveaboards)
- Surface marker buoy and reel (for safety in areas with boat traffic)
- Reef-safe sunscreen and hat (for between-dive sun protection)
- DIN adapters if your regulator uses DIN fittings
- Spare mask and fin straps (difficult to replace in remote areas)
Health & Safety Considerations
- Ensure your dive insurance is current and covers remote locations
- Bring basic medications (seasickness pills, antibiotics, pain relievers)
- Consider malaria prophylaxis (consult your travel doctor)
- Stay well-hydrated between dives to reduce decompression risk
- Respect no-fly times (24-48 hours) after your last dive
Medical Resources: The nearest hyperbaric chamber is located in Port Blair. Some remote itineraries may be 12+ hours from medical facilities, so comprehensive dive insurance with evacuation coverage is essential.
Travel Logistics
Most Andaman liveaboards depart from Port Blair, which is accessible via flights from major Indian cities like Chennai, Kolkata, and Delhi. Allow at least one day before your liveaboard departure to account for potential flight delays and permit processing.
Permit Requirements: Foreign nationals require a Restricted Area Permit (RAP) to visit the Andaman Islands. Most liveaboard operators will assist with obtaining this, but you’ll need to provide passport details well in advance.
