Alor
Alor, at the far eastern end of the Lesser Sunda chain, faces Pantar across a strait swept by cold, nutrient-loaded currents rising from the Savu Sea. The payoff for its remoteness is dramatic: fish-smothered seamounts, walls that drop into whale migration corridors, anemone fields covering entire slopes, and world-class muck in Kalabahi Bay. A handful of small resorts and seasonal liveaboards serve divers willing to travel this far.
Waarom hier duiken
Alor is what Indonesian diving looked like before crowds: villages that still greet visitors as an event, reefs that see a handful of boats a week, and water that can swing from bathtub-warm to jacket-cold inside one dive as upwellings push through the Pantar Strait. Those cold pulses are the engine. They feed schooling fusiliers, jacks, and dogtooth tuna at sites like Kal's Dream, keep coral cover dense, and draw deep-water visitors; molas, hammerheads, and passing whales all appear here without being promised. Clown Valley's slope disappears under carpets of host anemones on a scale few divers have seen anywhere. And when the strait blows, Kalabahi Bay's dark-sand muck produces rhinopias, frogfish, and octopus to rival Lembeh. Currents, thermoclines, and thin infrastructure make it an experienced diver's destination, best treated as an expedition rather than a resort holiday.
Maand voor maand
Operators run mainly from about March or April through November or December; the northwest monsoon of roughly December to February brings rain and wind that complicate the strait's crossings. Upwellings occur in all seasons and are strongest around the mid-year trades, so cold thermoclines are part of the experience rather than an anomaly, and many regulars rate September to November the sweet spot.
| Maand | Water | Zicht | Hoe het voelt |

| January●●○○○ | 24–28 °C / 75–82 °F | 10–20 m | Northwest monsoon; wind, rain, and limited operations. |
| February●●○○○ | 24–28 °C / 75–82 °F | 10–20 m | Low season continues; some resorts close or run reduced schedules. |
| March●●●○○ | 24–28 °C / 75–82 °F | 10–25 m | Season restarts as seas ease. |
| April●●●●○ | 24–28 °C / 75–82 °F | 15–25 m | Settled conditions; strait sites come back into rotation. |
| May●●●●○ | 23–28 °C / 73–82 °F | 15–30 m | Good diving; thermoclines begin to sharpen. |
| June●●●●○ | 21–27 °C / 70–81 °F | 15–30 m | Trades and upwelling build; cool, fish-rich water. |
| July●●●●○ | 20–26 °C / 68–79 °F | 15–30 m | Coldest pulses of the year; exposure protection earns its keep. |
| August●●●●○ | 20–26 °C / 68–79 °F | 15–30 m | Cool and lively; strong currents on the famous sites. |
| September●●●●● | 21–27 °C / 70–81 °F | 15–30 m | A favorite month: seas calm while the water stays rich. |
| October●●●●● | 23–28 °C / 73–82 °F | 15–30 m | Often the best all-around window; liveaboard traffic peaks. |
| November●●●●○ | 24–28 °C / 75–82 °F | 15–25 m | Late season remains reliable before the monsoon turns. |
| December●●●○○ | 24–28 °C / 75–82 °F | 10–20 m | Weather window closes; early-month trips can still work. |

Hoe kom je er & verblijf
Hoe kom je er: Fly to Kupang in West Timor, then take the short onward flight to Alor's Mali airport outside Kalabahi; ferries from Kupang and Flores exist for the patient. Resorts transfer guests by boat or road from Kalabahi.
Waar verblijven: A small cluster of owner-run dive resorts sits on the Alor and Pantar shores of the strait, plus simple guesthouses in Kalabahi town. Rooms are few; in season, book months ahead or come by liveaboard.
Kosten: The few resorts here mostly sell room-and-diving packages, and remoteness keeps prices above what the simple infrastructure might suggest; liveaboards visit on Banda Sea and Flores routes. Bring cash for Kalabahi, as payment infrastructure is limited.
Tussen de duiken door: Visit the traditional hilltop village of Takpala, browse Kalabahi's market and its famous ikat weaving, walk black-sand beaches, and watch for dolphins and pilot whales on crossings; kayaking and snorkeling fill calm afternoons.
Veiligheid & praktische zaken
Gevaren: Fierce, fast-switching tidal currents with down-current and washing-machine behavior at the strait's seamounts; cold thermoclines that shorten comfortable bottom time; extreme remoteness from medical care. Local guiding is not optional at the exposed sites.
Treat the strait like a tidal river: dive slack windows chosen by local guides, carry an SMB and audible signal, and keep group discipline tight. Pack exposure protection warmer than the tropics suggest, and hold conservative profiles given evacuation distances.
Dichtstbijzijnde recompressiekamer: There is no recompression chamber on Alor, and reaching one involves long-distance evacuation; carry insurance that covers air evacuation and route any incident through EMS and DAN immediately.
