Diving in Alor in November

Conditions in November

November in Alor ushers in a subtle shift in the diving conditions, marking the transition away from the peak dry season. You’ll find the weather generally pleasant, with daytime temperatures hovering around a comfortable 30-32°C (86-90°F). While the occasional afternoon shower isn't uncommon as the inter-monsoon period approaches, these are usually brief and do little to disrupt your dive plans. The sea state remains largely calm, particularly within the sheltered straits and bays, offering smooth sailing for liveaboards and comfortable entries and exits from the water.

Water temperatures in November are a delight, with surface readings typically ranging from 27-29°C (81-84°F). However, Alor is renowned for its upwellings, so expect cooler thermoclines, especially on deeper dives or at sites exposed to stronger currents. These colder currents can drop the temperature by a few degrees, sometimes as low as 24-25°C (75-77°F), making a thicker wetsuit a wise choice. Visibility is generally excellent, often exceeding 20-30 meters (65-100 feet), providing crystal-clear views of the vibrant reefs and passing pelagics. While some localized areas might experience slightly reduced visibility due to particulate matter closer to shore after a heavy rain, the majority of dive sites boast spectacular clarity. Currents, a defining feature of Alor's diving, are still very much present in November. These can range from gentle drifts to exhilarating rides, dictating the best time to dive certain sites and offering thrilling experiences for advanced divers.

What you will see

November is a fantastic time to dive Alor, offering a potent mix of large pelagics and an incredible abundance of macro life. The cooler, nutrient-rich upwellings that characterize this period act as a magnet for a diverse array of marine creatures. You stand an excellent chance of encountering various shark species, including grey reef sharks, whitetip reef sharks, and even the occasional hammerhead or thresher shark patrolling the deeper channels. Keep your eyes peeled into the blue; schools of barracuda, trevally, and fusiliers are common sights, often forming massive, swirling tornadoes of silver. While manta rays are present year-round, November can see good numbers as they feed in the plankton-rich waters, particularly at cleaning stations.

But Alor isn’t just about the big stuff. Its pristine reefs are a haven for macro enthusiasts. November continues to deliver an astonishing parade of critters. You'll find a bewildering variety of nudibranchs in every imaginable color and pattern, pygmy seahorses clinging to gorgonian fans, and a plethora of frogfish, stonefish, and scorpionfish masters of camouflage. Look closely for robust ghost pipefish, various species of clownfish nestled among their anemones, and intricate communities of crabs and shrimp. The vibrant soft corals, sponges, and tunicates paint an underwater garden that provides shelter and sustenance for this incredible biodiversity. The combination of nutrient upwelling and relatively stable conditions makes November a truly rewarding time for both wide-angle and macro photography.

Practical tips for your trip

Considering the potential for cooler thermoclines, we highly recommend you pack a 5mm wetsuit for your Alor liveaboard trip in November. While the surface water temperature is warm, those upwellings can be quite refreshing, and a thicker suit will ensure your comfort, allowing you to fully enjoy longer dives. This month is particularly well-suited for advanced divers who are comfortable with currents, as many of Alor's most iconic sites feature them. However, there are still plenty of sheltered bays and calmer dives available for less experienced divers or those looking for a more relaxed pace. Always discuss your comfort level with your dive guides; they are experts at selecting sites appropriate for the group.

Liveaboard availability in November tends to be good, as it's just before the peak holiday season, but booking in advance is always recommended, especially for popular boats. Beyond your diving gear, remember to pack reef-safe sunscreen, a good hat, and sunglasses for surface intervals. A lightweight rain jacket might also be useful for those occasional afternoon showers. Bring an adapter for Indonesian power outlets (Type C or F) and consider a small medical kit for common ailments. Finally, Alor is a remote destination, so be prepared for limited internet connectivity in some areas, allowing you to truly disconnect and immerse yourself in the natural beauty surrounding you.
