Across the Banda Sea's volcanic archipelago, liveaboard routes thread remote seamounts and channels where scalloped hammerheads appear in the blue during seasonal migration windows tied to monsoon shifts. This is expedition diving with long crossings between the Spice Islands and fewer boats than Komodo or Raja Ampat. Autumn from September through November marks the most cited hammerhead pulse on eastbound itineraries.

Up to 78% sighting chance in Banda Sea (Indonesia). Best months: October, September, November.
Two windows are cited: spring (March to May) and autumn (September to November), with autumn often preferred on liveaboard schedules.
Only liveaboard trips from Ambon, Saumlaki, or Maumere cover the Banda Sea hammerhead sites, typically 10 to 14 day itineraries costing 3,000 to 5,500 US dollars (2026 prices).
No. This is a migration corridor through the Spice Islands. Sightings are strong in season but depend on route, monsoon timing, and current.
Remote volcanic seamounts and channels see hammerheads during monsoon shift windows, with far fewer boats than Komodo or Raja Ampat.
Advanced open water and comfort in blue-water drifts and variable current are standard on Banda Sea expedition routes.
