In season (Oct)
SST 63°F in the prime band (59–66°F prime)
Charted 2585 ft suits this species (328–6560 ft ideal)
No strong temperature break nearby

No strong temperature break nearby
Deep-drop a rigged bait 350-500 m by day along canyon walls.
Sablefish (Black Cod) identification illustration
In season (Oct)
Bottom temperature unavailable here — surface water misreads a bottom fish, so temperature is not scored
Charted 2585 ft suits this species (984–2952 ft ideal)
Deep-drop bait on the slope in 1000-3000 ft — a long haul up for the best-eating fish out there.

SST 63°F in the prime band (63–72°F prime)
Charted 2585 ft suits this species (131–1640 ft ideal)

SST 63°F in the prime band (59–70°F prime)
Charted 2585 ft marginal for this species (98–1312 ft ideal)
No strong temperature break nearby
Slow-trolled bait or a chum slick where bait stacks on a break — they stun with the tail, so hook-ups run tail-first.
Mahi-Mahi identification illustration
In season (Oct)
SST 63°F outside preference (75–86°F prime)
Charted 2585 ft suits this species (131–6560 ft ideal)

Derived from the tide at MONTEREY, MONTEREY BAY — flow peaks near mid-tide, goes slack near high and low. No tidal-current station within 10 nm of this spot. Timing only — it never changes the habitat scores above.

Drag the graph for any hour — wind, gusts, seas & period, rain, predicted current. The pale band around the wind line is model disagreement; the day chips carry the verdict and the number that caused it; the moons are real phases.
