**Pack for Alor diving around water that swings from 25°C to 32°C: carry both a 3mm and a 5mm exposure layer, your own dive computer, a tall delayed SMB with reel, spare mask and fin straps, and proof of DAN-style dive-accident insurance. The nearest recompression chamber is in Bali, so redundancy is not optional.**
Why does packing for Alor differ from a Bali or Gili trip?
Alor sits at the eastern edge of East Nusa Tenggara, deep inside the Coral Triangle, and it does not run on the same logistics as Bali or the Gilis. Boats leave from Kalabahi Bay and reach 40-plus dive sites within 30 to 45 minutes, but the town itself is small, ATMs are limited, and the nearest recompression chamber is a flight away in Bali. What you forget, you generally dive without.
The Pantar Strait is also a marine protected area with real rules. Every diver attends a mandatory briefing by MPA officers, pays a marine park fee, and carries a permit before entering the water. Guides need special MPA certification on top of standard agency cards, dives are strictly no-decompression, and solo diving is not allowed. Operators typically want 50 to 100 logged dives before they are comfortable putting you in the current here, so keep your logbook and certification cards where you can reach them. If you are still weighing dates and logistics, our Alor diving holiday packages lay out how permits, briefings and boat schedules fit together across a typical week.
What exposure suit do you need for 25-32°C water?
Alor water temperature moves with the season, so a single wetsuit rarely covers a full trip. As of 2026, surface water runs about 25°C in March-April and October-November, then climbs to 31-32°C from May to September during the southeast monsoon. Thermoclines are the twist: some sites drop to 20°C or lower once you descend, which changes what “warm” Alor really means.
| Season | Typical surface temp | Suggested exposure |
|---|---|---|
| May–September | 31–32°C | 3mm full suit; hooded vest for thermoclines |
| March–April | ~25°C | 5mm full suit, or 3mm plus hooded vest |
| October–November | ~25°C | 5mm full suit; pelagic season, longer dives |
| Deep / thermocline (any month) | 20°C or lower | Add a hood; consider 5mm |
Bringing both a 3mm and a 5mm, or a 3mm paired with a hooded vest, is the flexible answer. Multi-dive days in current steal body heat faster than a single relaxed reef dive, so err warmer than the surface reading suggests.
Which safety and signaling gear is essential in the Pantar Strait?
Pantar Strait currents are strong. Descents are fast, equalising has to keep pace, and groups regroup around 5 metres before drifting as a unit. Solid signalling and redundancy are not accessories here — they are the difference between a clean pickup and a long float.
- Dive computer (bring your own): all dives are no-deco with a 60-minute or 50-bar limit; a personal unit you trust beats any rental.
- Tall delayed SMB plus reel or spool: boats need to spot you fast on a drift finish across open water.
- Audible signal and mirror: a whistle or air horn and a signal mirror help surface pickups in chop.
- Backup mask: a flooded or lost mask ends a dive you cannot easily repeat the next day.
- Reef hook (ask first): handy in current, but confirm with your operator, since MPA rules protect the reef and not every site permits it.
- Primary and backup torch: wall overhangs and muck sites reward good light even in daylight.
What remote-region and spares kit belongs in your bag?
This is where Alor separates prepared divers from stranded ones. DAN or equivalent dive-accident insurance is mandatory, not a suggestion: the nearest hyperbaric chamber is in Bali, and evacuation plus chamber costs are not covered by standard medical or travel insurance. Buy or renew it before you fly, and carry the membership details in writing.
Cash matters too. Kalabahi has few reliable ATMs, and the marine park fee, tips and incidentals are easier in rupiah you already hold. A compact save-a-dive kit rounds it out.
| Category | Pack this | Why it matters in Alor |
|---|---|---|
| Insurance & docs | DAN-style dive cover, logbook, cert cards, permit money | Chamber is in Bali; operators check experience |
| Save-a-dive kit | Mask/fin straps, o-rings, mouthpiece, zip ties, silicone grease | No dive shop nearby for spares |
| Health | Personal meds, seasickness tablets, rehydration salts, ear drops | Small boats, long transfers, warm humid days |
| Sun & skin | Reef-safe sunscreen, rash guard, wide hat, lip balm | MPA protects reefs; long surface intervals |
| Camera (muck) | Macro rig, focus light, spare batteries, memory cards | Kalabahi Bay black-sand muck is macro-rich year-round |
| Cash | Rupiah for marine park fee, tips, extras | Limited ATMs in Kalabahi |
Kalabahi Bay’s volcanic black sand is a muck-diving hotspot for macro shooters — Pegasus sea moths, mimic octopus, seahorses, nudibranchs and frogfish — and because those critters stay put, the muck stays good year-round. If you shoot, a focus light and spare batteries earn their space in the bag.
Frequently Asked Questions
Can I rent scuba gear in Alor, or should I bring my own?
Established Alor operators such as Dive Alor Dive and Alami Alor rent standard kit, but stock is finite and the region is remote. Bring personal-fit items you rely on — mask, computer, exposure suit and SMB — and treat rental as backup. Confirm sizes and availability in advance, because a shop restock is not a quick errand in Kalabahi.
Is a dive computer mandatory for diving in Alor?
Practically, yes. Alor dives are all no-decompression with a 60-minute or 50-bar limit, and strong-current profiles make tracking depth and time essential. Many operators expect every diver to wear a personal computer rather than share one. Bring your own model you know well, plus a spare battery, and log dives carefully across multi-dive days.
Do I need special insurance to dive in Alor?
Yes. DAN or equivalent dive-accident insurance is required because the nearest hyperbaric chamber is in Bali, and evacuation and chamber treatment are not covered by standard medical or travel policies. Arrange or renew cover before departure, carry written membership details, and check that your plan covers the depths and conditions you plan to dive.
