Truk Lagoon, Chuuk, Micronesia · 9–34m · intermediate · sheltered

Wartime freighter upright on the lagoon floor, holds still loaded. The barrier reef blocks the ocean swell, which is why Truk dives in most weather; wind chop across the lagoon is the limiting factor.

Ranges span today's hours. Wave height here is the raw sea state — the rating scales it for how exposed the site is. Sheltered — reef or lagoon protection, so swell is scored at half its open-water height.

Dive briefing

AI-generated

Conditions are marginal today. Short-period chop across the lagoon is making for choppy water despite the barrier reef's shelter from ocean swell. The rating reflects 0.5m effective waves compounded by that short-period sea state. Water temperature sits between 28.8 and 29.1°C. You'll need intermediate certification to dive here.

The wreck sits upright on the lagoon floor between 9 and 34 metres, with holds still loaded. Divers commonly log peacock damsels, bluefin trevally, barcheek trevally, masked rabbitfish, bleeker's parrotfish, and pink skunk anemonefish around the site. Bigeye trevally and threadfin butterflyfish are also often recorded.
