Wolf Island
Cooler current season is favored for whale sharks and schooling sharks.
Wolf is Darwin's sibling and the other half of every northern Galápagos itinerary — hammerheads, Galápagos sharks, dolphins and the occasional orca patrol the points, with a hard-bottom plateau that lets you hook in and watch the show. Many divers consider Wolf the more consistent of the two.
Good season
Same seasons as Darwin: June–November is cool and pelagic-rich; December–May is warm with bigger hammerhead schools.
Trip duration
Visited as part of a 7-night Darwin/Wolf liveaboard.
Dive style
Negative entries, reef hooks, blue-water safety stops. 3–4 dives per day.
Dive level
Advanced + 50–100 logged dives.
Reef health
What you’ll actually findSome loss since the 2010s, but the reef still has plenty to dive. Pick depth and shoulder-season carefully.
Coral reef health
How is this calculated?On current trend, no live coral by ~2078. Losing about 0.5% cover per year — roughly 54 years of reef left to see if nothing changes.
Heat stress right now
Mild warmth. Worth watching — no bleaching yet.
NOAA Coral Reef Watch · updated May 2026 · 15.6 °C-week heat dose
What to expect on a dive
Galápagos reefs are naturally sparse — pelagic mass aggregation is the entire experience. Hammerheads, whale sharks, mobulas.
Sources, methodology, and the raw numbers
Raw observed numbers
- Coral cover: 27% (survey Sep 2024, Eastern Tropical Pacific reef survey)
- Bleached: 12%
- Recent mortality: 4%
- Eastern Tropical Pacific — observed condition reflects the thinning regional pattern.
Raw thermal numbers
- NOAA CRW alert level: Watch
- Degree Heating Weeks: 15.6 °C-wk
- SST anomaly: +1.5 °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 to bringSite-specific add-ons
Some dive sites here call for extra gear. Check the individual site page for full context.
- Coldwater wetsuit + hood — Humboldt upwellings drop temp to 19°C in season — third dive of the day is the cold one. · Shark Bay (Wolf Island)
- Reef hook — Hooking is the only way to hold the line while hammerheads pass. · Shark Bay (Wolf Island)

What divers say
“If Darwin is the headline, Wolf is the album. More dives, more variety, fewer crowds in the water column.”
