Alor is defined by its intensity: strong currents, volcanic topography, and a cryptic species list that rewards patient, observant divers. Sites range from muck slopes and black-sand bays, such as Ampera, to dramatic walls and drift dives like Bama Wall and Biatabang off Ternate Island. Scorpionfish, Ribbon Eel, Mandarinfish, and Spanish Dancer are regularly encountered. Most diving is boat-accessed and suits intermediate to advanced divers, though beginner-friendly muck sites are available.
Monthly water temperature across Alor's sites, from satellite sea-surface data corrected for depth. The band shows the site-to-site spread.
Water temperature stays consistently warm throughout the year, with a slight dip mid-year and peaks in the final months of the year. The best conditions cluster around April and November, when visibility tends to be strong and currents are most reliably manageable. Mid-year diving remains worthwhile but can bring more challenging conditions, particularly at exposed drift and wall sites.

Most sites in Alor are pitched at intermediate or advanced level, with strong currents and deeper profiles at walls such as Bama Wall and Biatabang. However, Bakalang Jetty is listed as beginner-friendly, offering a muck and reef environment at accessible depths. Ampera also provides a gentler entry point with shallow options available. Beginners are best placed with an operator who knows current conditions.
The vast majority of sites in Alor require boat access, including all the major drift and wall dives. Ampera is the notable exception, where both shore and boat entry is available. Alor Divers Housereef also offers a shore entry option. With a good number of operators based in the area, including Alami Alor Dive and Snorkel Resort, Alor Divers, and Lazy Turtle Dive, boat trips are straightforward to arrange.
Alor offers a real contrast between site styles. Drift and wall sites such as Heaven Alley, Biatabang, and Bama Wall deliver fast-paced diving along coral-covered vertical topography. Muck sites including Ampera and Bakalang Jetty reward slower, macro-focused dives on sandy and volcanic slopes. Pasir Merah adds geological interest with bubbling gas vents on a volcanic red sand slope near Pura Island.
