Bluefin fishing out of Morro Bay means a long run north up the Big Sur coast and then a turn offshore, and the length of that run sets the day. This guide covers when the fish are around, how far boats go, the grounds that hold them, the local method, and who fishes the port. Harbor entrance, ramp and conditions detail is in the Morro Bay port guide.
When bluefin are off Morro Bay

Peak bluefin season out of Morro Bay is June through September, according to a FishingBooker guide. The same guide says bluefin turn up outside those four months too, but those are the months to plan around.
For how bluefin move along the coast and the biology behind the timing, see the Pacific bluefin tuna guide and the Pacific Southwest bluefin guide (see also the wider Pacific Southwest guide).

How far boats run from Morro Bay

The standard bluefin day from Morro Bay is a long run north, then a turn offshore. Check the official NWS marine forecast for wind, wave height and period before committing to the run, since those numbers decide whether the day happens.
The 60-mile run north
Central Coast Fishing Charters runs a 12-hour Lopez Point / Offshore private trip. The boat goes 60 miles up the coast for groundfish in the morning, then offshore for tuna in the afternoon. That is the template for a combo day, and you can follow the same sequence on your own boat.
Cape San Martin, on the Big Sur coast, is also about 60 miles north of Morro Bay, according to FishingBooker.
The offshore leg
The afternoon tuna leg turns offshore from the coastal grounds and passes beyond state waters. The Regulations section below covers what that means for the rules.
Grounds and structure that hold fish

The grounds run from the bottom you already fish in Estero Bay north to the Big Sur coast.
| Ground | Direction from harbor | What it is |
|---|---|---|
| Hazard Canyon Reef | South | Near Montaña de Oro State Park, just south of Morro Bay |
| Piedras Blancas Lighthouse area (San Simeon / "Jurassic Park") | North | Lighthouse area off San Simeon |
| Cape San Martin (Big Sur) | North | About 60 miles north, per FishingBooker |
Estero Bay bottom spots
This is the nearshore bottom at the harbor’s door, used for the groundfish or fallback leg of the day.
Hazard Canyon Reef
Hazard Canyon Reef is nearshore structure on the south side of the harbor, near Montaña de Oro State Park, just south of Morro Bay.
Piedras Blancas and San Simeon ("Jurassic Park")
"Jurassic Park" is the name for the Piedras Blancas Lighthouse area off San Simeon, north of Morro Bay. Chart Contours shows the bottom around Piedras Blancas and Cape San Martin. Chart layers are not for navigation.
Lopez Point
Lopez Point, on the Big Sur coast, is the named destination of the 12-hour Lopez Point / Offshore trip. The morning groundfish leg ends here and the turn offshore begins.
Cape San Martin
Cape San Martin sits on the Big Sur coast, about 60 miles north of Morro Bay, according to FishingBooker.
How bluefin are fished locally

A FishingBooker Morro Bay guide says slow trolling is often the technique of choice for bluefin out of Morro Bay. For broader technique and tackle, see our tuna fishing guides.
Slow trolling
Anglers trail baited lines behind a moving boat and cover water until something eats.
Fish size and gear
Bluefin here often run well over 100 pounds, per FishingBooker, so gear has to match fish that size.
Bonito on the same trips
Reports mention bonito as bycatch on the same trips as bluefin.
Who fishes for bluefin out of Morro Bay
Charters and private boats follow the same pattern: groundfish up the coast early, tuna offshore later.
Charters and the combo day
Central Coast Fishing Charters runs the 12-hour Lopez Point / Offshore private trip. It shows most clearly how the port is fished: a long run north, bottom fish first, tuna later.
Private boats
If you run your own boat, you can follow the same sequence, with coastal grounds in the morning and the offshore leg in the afternoon. The go or no-go call rests on the run length and the NWS forecast numbers. We don’t promise fish; we help you decide where to look.
