Sint Eustatius · Caribbean
St. Eustatius Marine Park
Best weather usually falls outside the late-summer storm season.
Sint Eustatius (Statia) is Saba's sister Dutch Caribbean island — historic colonial wrecks, healthy reefs, and even fewer divers than Saba. The marine park is strictly protected.
Good season
Year-round; May–October is calmest.
Trip duration
5–7 nights.
Dive style
Wreck and reef diving on volcanic topography; mild current.
Dive level
Open Water.
Reef health
What you’ll actually findThis reef is losing coral faster than it's recovering. If it's on your list, go sooner — and manage expectations on coral colour.
Coral reef health
How is this calculated?On current trend, no live coral by ~2044. Losing about 1.1% cover per year — roughly 20 years of reef left to see if nothing changes.
Heat stress right now
No abnormal heat right now. Corals stay coloured.

What to expect on a dive
Volcanic reef and wreck diving. Cover has thinned; macro and structure remain the draw.
Sources, methodology, and the raw numbers
Raw observed numbers
- Coral cover: 22% (survey Sep 2024, NCRMP Caribbean biological transect)
- Bleached: 20%
- Recent mortality: 8%
- Caribbean post-2023 — observed condition reflects the declining regional pattern.
Raw thermal numbers
- NOAA CRW alert level: No stress
- Degree Heating Weeks: 0 °C-wk
- SST anomaly: +0.4 °C
How we summarise this
Observed coral cover, bleaching, and mortality come from named in-situ surveys with a stated date and method — they describe one snapshot of one reef and do not extrapolate to neighbouring sites. Current thermal stress is satellite-derived from NOAA Coral Reef Watch at ~5 km resolution; it indicates risk, not observed coral damage. We deliberately separate observed condition, current thermal stress, and projection — and we never publish a projection without a documented model and uncertainty.

What you can do
STENAPA manages the Statia National Marine Park. Caribbean MPAs (Cayman, Saba, Bonaire, Bonaire, Cuba JdR) are some of the world's best-managed. Pay the conservation tag fee at entry and join a lionfish cull if offered.
Protection status sourced from Protected Planet / WDPA and refined with Marine Protection Atlas. Fishing pressure proxy is Global Fishing Watch AIS data. See the methodology for what these sources can and can’t prove.

Some dive sites here call for extra gear. Check the individual site page for full context.
- Primary dive light — The superstructure swim-through and the wreck's interior compartments are dark even at midday; a torch reveals the cup coral, sponges and moray eels colonising the steel. · Charles L. Brown Wreck
- Nitrox and dive computer — With most of the structure sitting between 20 and 30 m, enriched air meaningfully extends bottom time on this deep wreck while a computer tracks the multi-level profile. · Charles L. Brown Wreck
What divers say
“Statia is Saba's quieter sibling. If 'fewer divers' is your priority, you've found it.”
