Month-by-Month Guide to Southeast Asia’s Most Incredible Marine Encounters 🐠🌊
Planning the perfect dive trip in Southeast Asia is all about timing. While the region offers fantastic diving year-round, certain months bring spectacular wildlife events, optimal conditions, and unique photographic opportunities that every diver should experience at least once. This guide takes you through January to December, highlighting the top destinations, the marine life you’re most likely to encounter, and tips for capturing those moments on camera.
A Beautiful Golden Sunset in Raja Ampat
January – Raja Ampat, Indonesia
Why Go: The heart of the Coral Triangle and one of the most biodiverse places on Earth. January offers calm seas and crystal-clear waters, perfect for exploring the region’s iconic reefs.
Key Encounters: Pygmy seahorses, manta rays at cleaning stations, wobbegong sharks, and vast schools of fusiliers.
Photography Tip: Mix macro lenses for tiny critters with wide-angle for mantas and reefscapes. Early morning dives bring the best natural light.
February – Similan Islands, Thailand
Why Go: Peak season for Thailand’s west coast. Visibility often exceeds 30 meters, and the reefs are teeming with life.
Key Encounters: Leopard sharks, giant trevallies, and the occasional manta ray.
Photography Tip: Use a dome port for split shots of crystal bays and underwater scenes. Keep your strobe arms wide to reduce backscatter in clear water.
March – Tubbataha Reefs, Philippines
Why Go: The UNESCO-listed Tubbataha only opens from mid-March to mid-June, offering pristine conditions and no permanent human settlement.
Key Encounters: Whale sharks, hammerhead sharks, and massive schools of jacks.
Photography Tip: For pelagic shots, get low in the water column and shoot slightly upward to include the blue water background.
Labuan Bajo - The gateway to scuba diving in Komodo
April – Komodo National Park, Indonesia
Why Go: April marks the start of calmer conditions and excellent visibility before peak season.
Key Encounters: Manta rays, reef sharks, turtles, and colourful soft corals.
Photography Tip: Use wide-angle lenses for drift dives; position yourself downcurrent for dramatic shots of mantas as they glide toward cleaning stations.
May – Cenderawasih Bay, Indonesia
Why Go: This remote bay offers some of the most unique whale shark encounters on the planet.
Key Encounters: Juvenile and adult whale sharks lingering around fishing platforms (bagans).
Photography Tip: Shoot in natural light with a wide-angle lens; try an upward angle for scale against the sun’s rays.
June – Gili Islands, Indonesia
Why Go: Great weather and calm seas make it a turtle paradise.
Key Encounters: Green turtles, hawksbill turtles, and reef fish galore.
Photography Tip: Experiment with split shots in shallow water, capturing both the turtle and the island backdrop.
July – Wakatobi, Indonesia
Why Go: Incredible coral gardens with unmatched health and colour during this time of year.
Key Encounters: Anthias, nudibranchs, pygmy seahorses, and reef sharks.
Photography Tip: Use a mid-range zoom for flexibility between coral close-ups and fish portraits.
August – Lembeh Strait, Indonesia
Why Go: Year-round muck diving heaven, but August offers excellent visibility and critter activity.
Key Encounters: Rhinopias, flamboyant cuttlefish, mandarinfish, and frogfish.
Photography Tip: A snoot is great for highlighting unusual shapes and colours in the black sand background.
September – Banda Sea, Indonesia
Why Go: It’s hammerhead season! Remote and spectacular, with pelagic action at its peak.
Key Encounters: Schooling hammerhead sharks, mobula rays, and Napoleon wrasse.
Photography Tip: Keep your profile low and be patient; let the school come to you for the cleanest composition.
October – Alor, Indonesia
Why Go: Shoulder season means fewer divers and thriving marine life.
Key Encounters: From macro nudibranchs to large pelagics like mola mola.
Photography Tip: Bring both macro and wide-angle setups if on a liveaboard, as conditions can vary dramatically dive-to-dive.
November – Bali, Indonesia
Why Go: Excellent diving conditions in Tulamben, Nusa Penida, and Padang Bai before rainy season peaks.
Key Encounters: Mantas, macro critters, and sometimes mola mola at depth.
Photography Tip: For shallow reef shots, use a red filter to balance colours; strobes for deeper wreck or muck dives.
December – Sipadan, Malaysia
A Split Shot Showing a School of Bumphead Parrotfish & the Famous Sapidan Island, Malaysia
Why Go: One of the world’s most famous dive sites, December brings good visibility and warm waters.
Key Encounters: Barracuda tornadoes, bumphead parrotfish, turtles, and reef sharks.
Photography Tip: Use fast shutter speeds to freeze schools of fish in motion and keep the background blue.
Travel Tips for Underwater Photographers
Packing Gear: Keep cameras, lenses, and housings in carry-on where possible. Use padded dividers.
Humidity Control: Silica gel packs and airtight dry boxes are essential between dives.
Battery & Memory: Charge between dives on liveaboards; bring multiple memory cards to avoid mid-trip data issues.
Corrosion Prevention: Rinse gear thoroughly in fresh water after each dive and dry before storage.
