California Halibut

Paralichthys californicus. Prime water reaches San Francisco in California right now (54°F on the bottom). Fish it 16–52 ft down — that is where 59–57°F water sits off San Francisco.

The strip is the water itself, coloured by temperature from the surface down to the 52 ft surveyed bottom at that spot — one band per RTOFS model level. The outlined stretch is where California Halibut's temperature band (54–72°F) and the depth it holds actually overlap. That thickness is the number that matters: it is how much water you can work, not just whether the spot is warm enough somewhere. One model cycle, not a weekly archive — this holds still while the surface map scrubs.

How it's fished

Drift live bait or swimbaits over sand flats adjacent to structure.

"Fish it at" is where this species' temperature band and its holding depth overlap in the water column, from the RTOFS profile (13 levels, 0–300 m) — the depth to actually put a bait, not just the place. "Prime water" is the furthest sampled station on the 10-fathom lane whose seabed temperature sits inside this species' band. It is water, not a sighting report.
