Budget at least five diving days for Alor, which usually means a seven-day trip door to door. Alor sits far out in East Nusa Tenggara, so two days vanish to flights and the mandatory marine-park briefing. Five diving days at two to three dives each lets you cover walls, muck, and a real shot at pelagics.
That is the short version. The longer answer depends on how you reach Alor, how many dives your body can handle in current, and whether you are chasing macro in Kalabahi Bay or wide-angle drift in the Pantar Strait. Here is how to size your trip honestly.
Why does Alor eat more days than Bali or Komodo?
Distance. Alor is not a quick hop. Most divers fly Bali to Kupang, then Kupang to Alor’s Mali Airport, and the connections do not always line up on the same day. Plan one full day to arrive and one full day to fly home.
Then there is paperwork that Alor takes seriously. Alor’s waters are managed as a marine protected area, and as of 2026 every diver, snorkeller and marine tourist must attend a mandatory briefing by MPA officers, pay a marine park fee, and hold a permit before any in-water activity. Guides need special certification to lead inside the MPA on top of standard agency cards, and diver numbers per site are capped by a WWF-determined carrying capacity. None of this is a formality you can skip.
So a “seven-day Alor trip” is not seven days of diving. It is two travel days, a lighter first day for the briefing and a check dive, and four to five real diving days.
How many dives can you actually do per day?
Two to three. Alor is an advanced destination — typical dives run 15 to 25 metres, the Pantar Strait throws strong surface currents that demand a fast descent and a regroup around five metres, and every dive is no-decompression. Operators generally cap bottom time at 60 minutes or when a diver hits 50 bar, and solo diving is not allowed. That physical load, plus real surface intervals, keeps most people at two or three tanks a day.
| Trip length | Travel days | Diving days | Approx. dives |
|---|---|---|---|
| 5 days | 2 | 3 | 6-8 |
| 7 days | 2 | 4-5 | 10-14 |
| 10 days | 2 | 7-8 | 16-22 |
Arrive comfortable, too. Most Alor operators ask for a minimum PADI Open Water card but suggest 50 to 100 logged dives before you tackle Alor-Pantar currents. If you are freshly certified, a shorter, gentler trip is the honest call.
What does a seven-day Alor trip look like?
Seven days is the sweet spot for a first visit. You get enough water time to mix muck and wide-angle without rushing, plus a small weather buffer. If you want that rhythm tuned to your certification level, target species and travel dates, a custom Alor diving expedition can shuffle the diving days around weather and your pelagic priorities rather than forcing a fixed schedule. A typical land-based plan from a Pantar resort — many sit within 30 to 45 minutes by boat of 40-plus dive sites — runs like this:
- Day 1 — Fly in, settle, gear check, MPA briefing and permit.
- Day 2 — Check dive plus two easy Kalabahi Bay muck dives.
- Days 3-5 — Two to three dives daily across Pantar Strait walls and macro sites.
- Day 6 — Morning dives, then a mandatory dry afternoon before flying.
- Day 7 — Fly home.
One rule nobody at Currentline Alor will bend: never dive on the day you fly. The nearest hyperbaric chamber is in Bali, DAN or equivalent dive-accident insurance is mandatory here, and standard medical insurance does not cover chamber or evacuation costs. Build the dry buffer in and treat it as non-negotiable.
Is ten days better for Alor diving?
If pelagics are the point, yes. Blue-whale and hammerhead encounters in Alor are possible but never predictable, and the more days you spend in the water, the better your odds. The Pantar Strait favours wide-angle — schooling fish, mola mola, dolphins, pilot whales and the occasional orca — while one documented scalloped-hammerhead site drops to around 32 metres in very strong current and asks for real fitness. You want spare days to wait for the right window.
| Factor | 7-day trip | 10-day trip |
|---|---|---|
| Real diving days | 4-5 | 7-8 |
| Weather buffer | Thin | Comfortable |
| Pelagic odds | One or two tries | Several tries |
| Best for | First visit, macro focus | Wide-angle, hammerhead, mola mola |
September is the standout month to look for mola mola, so if that sunfish is on your list, a longer trip built around the September-October shoulder gives you room to keep trying. Mainstream liveaboards such as a Seven Seas Alor Sea itinerary run their seasonal Alor-Pantar trips in that same window, boarding at Kalabahi Bay.
What if you only have one week total?
Then treat the week as five diving days maximum and protect them. Fly in on the first possible connection, do not over-schedule the arrival day, and accept that one week means either macro-heavy Kalabahi Bay diving — which stays good year-round because the critters don’t travel far — or Pantar wide-angle, not an exhaustive tour of both. Trying to cram everything into six water days in strong current is how tired divers make mistakes.
A one-week trip also leaves almost no slack for weather. If a plankton bloom drops visibility below 15 metres in the May-to-September months, or currents turn heavy in October and November, you cannot simply push a lost day to next week. Go in with a flexible site plan and a guide who reads conditions daily.
How do seasons change the day count?
Conditions are best from April to November, with October and November bringing the most prevalent — and strongest — currents. The roughly November-to-March rainy season brings unsettled surface, rain and reduced visibility, so trips in that window benefit from an extra buffer day. Water sits near 25°C in March-April and October-November, warms to 31-32°C from May to September, and thermoclines can push some sites down to 20°C or lower.
- April-June — Warming water, building visibility (up to about 40 m in the dry June-October stretch); 6-7 days comfortable.
- July-September — Warm, occasional plankton blooms dropping viz toward 15 m; September best for mola mola, so lean 8-10 days.
- October-November — Strongest currents and prime pelagic odds; 8-10 days rewards patience.
- December-March — Wetter, less settled; add a buffer day and keep plans loose.

Frequently Asked Questions
Can I dive Alor over a weekend?
Realistically, no. Two of any short trip’s days go to flights between Bali, Kupang and Alor, and the mandatory MPA briefing and permit eat into your arrival day. A weekend leaves barely one diving day for an advanced, current-swept destination — not enough to justify the travel. Give Alor five days minimum.
How many days should a first-time Alor diver book?
Seven days is the sweet spot for a first visit. It yields four to five real diving days, a lighter briefing-and-check-dive start, and a small weather buffer. That is enough to sample both Kalabahi Bay muck and Pantar Strait walls at a safe two-to-three dives per day, without rushing your surface intervals or your nerves.
Do I need extra days to see blue whales or hammerheads?
Yes, build in spare days. Blue-whale and hammerhead sightings in Alor are possible but never predictable, and more water time simply improves your odds. A 10-day trip with seven or eight diving days gives you several tries at wide-angle Pantar sites and the deep, high-current hammerhead site, rather than a single roll of the dice.
