About Broadbill Swordfish
The broadbill swordfish is a different tier of fishing than anything else in SoCal. Where bluefin are technically demanding and dorado are accessible, swordfish fishing sits at the intersection of serious deep-water gear, long-range boats, and a significant amount of waiting.
Swordfish are not reef or nearshore fish — they're open-ocean deepwater predators. Daytime, they sit at 1,000 to 2,000 ft below the surface following the deep scattering layer (the dense band of squid and small fish that migrates vertically through the water column). At night, they surface-feed under low light. The FishBase species max is around 455 cm and 650 kg; the IGFA all-tackle world record stands at 1,182 lbs. Off San Diego, most recreational fish are 60 to 200 lbs.
The California swordfish fishery has two modes: night drift (the traditional method) and daytime buoy-drop jigging (the newer program that's brought more anglers into the fishery since around 2012). Both produce fish.
How to Catch
Night squid drift is the classic method. The boat anchors up offshore after sunset, crew rigs 1 to 2 lb live squid on 11/0 to 12/0 circle hooks, attaches a light stick to the leader, and floats the bait under a balloon at 60 to 100 ft. Swordfish come up to feed in the dark. The bite typically comes 2 to 5 hours after sunset. When the balloon disappears, you're on. The fight on a large swordfish is a grinding hour of slow, heavy resistance — nothing acrobatic, just power and weight.
Daytime buoy-drop works differently. The boat deploys a buoy rig that suspends a rigged bait or heavy jig at depth — 500 to 2,000 ft — during the day. Multiple buoys can be deployed. When a swordfish takes the bait, the buoy goes under. This method requires patience (watching buoys for hours) but allows day-trip access to the fishery. Heavy slow-pitch jigs (500 to 800g) are also used in the daytime program, dropped to depth and worked vertically.
Gear is heavy by necessity. A 200-lb broadbill at the end of a 1,500-ft drop is a technical fight.
Eating Profile
The best eating fish in the offshore SoCal program, by many anglers' reckoning. Swordfish flesh is white, firm, mild, and has a slight sweetness with no fishiness whatsoever. A 1-inch steak grilled over hardwood at high heat — 3 to 4 minutes per side — is the standard preparation. The firm texture holds up well to grilling; swordfish steaks don't fall apart.
Unlike tuna, swordfish benefits from a brief soy-and-citrus marinade. Keep it out of the freezer if possible — it's best fresh. The bloodline in swordfish is not strongly flavored the way tuna's is; many anglers leave it in.
Common Mistakes
- Under-rigged for the fish. A 60-lb class rod with 50 lb line is undergunned for a 150-lb swordfish at the end of 1,500 ft of water. Go 80–130 lb class standup with a large 2-speed reel and 2,000+ yards capacity.
- Wrong hook style. Circle hooks are standard for swordfish bait fishing — the fish swims away from the pressure and self-sets. J-hooks require a hard swing; many anglers miss the bite or gut-hook the fish.
- Assuming a permit is required. Recreational rod-and-reel swordfish fishing off California requires no HMS permit. That's a commercial longline requirement. Fish away.
- Night timing too early. The swordfish bite on night drifts typically doesn't develop until 2 to 5 hours after dark. Anglers who pull the bait at midnight and go to sleep miss the 2 AM bite. The overnight program exists for a reason.
Month-by-Month
- Jan–May: Cold water, no swordfish program. Boats are running for bluefin and other species.
- Jun: Season starts for dedicated swordfish programs. Early fish on deeper overnight runs.
- Jul–Sep: Peak. Night drift and daytime buoy-drop both producing. Best window for bigger fish.
- Oct: Tailing off. Water cools, fish move deeper or farther offshore.
- Nov–Dec: No swordfish program from SoCal. Long-range boats occasionally pick up fish deeper south.
