Tuna are the hardest-pulling fish in SoCal waters — and convincing one to eat an artificial lure instead of live bait is one of the most rewarding things you can do on the ocean. Bluefin and yellowfin both respond to lures, but they’re far pickier than species like dorado or yellowtail. The right lure, fished at the right speed and depth, puts fish on the deck. The wrong one gets ignored while the guy next to you on live bait goes tight.
Bluefin show up in SoCal when water temperatures hit 60–72°F, typically from late spring through fall, with the biggest fish arriving in summer. Yellowfin prefer warmer water — 68°F and above — and overlap with bluefin from midsummer through fall. Both species follow bait — sardine, anchovy, squid, and mackerel schools that stack up along temperature breaks and current edges. Use the SST chart and chlorophyll map to find productive water where bait is concentrating — that’s where the tuna will be.
⚡ Quick Picks
Best trolling lure: Cedar plugs — proven bluefin and yellowfin producer, run them behind every offshore spread.
Best trolling spread: Zuker feather jigs — run 4–6 at staggered distances in blue/white and black/purple.
Best casting lure: Tady 45 surface iron — the SoCal standard when tuna are crashing bait on top.
Best deep trolling: Rapala X-Rap Magnum — gets down 15–20 feet where tuna cruise below the surface.
Best surface lure: Poppers — when tuna are blowing up on bait, nothing beats a popper eat.
Trolling Lures
Trolling is how most tuna trips start — you cover ground until you mark fish on the meter, find temperature breaks, or run into birds working bait. A spread of 4–6 lures at staggered distances behind the boat works while you search, and a hookup on the troll often signals a school underneath that you can then stop on and fish with bait or casting lures. Run your spread at 6–8 knots for bluefin, 7–9 knots for yellowfin.
Cedar Plugs
Bluefin are notoriously boat-shy — they spook from hull noise and surface disturbance more than any other SoCal tuna. This is what makes cedar plugs the ideal bluefin trolling lure: run them 100–150 feet back and they’re out of the boat’s pressure zone entirely, working through clean, undisturbed water where nervous bluefin feel comfortable eating. For yellowfin, shorter leads (50–80 feet) work fine — they’re less cautious and will track a lure right into the prop wash. Natural cedar and blue/white are the standard daytime colors; black/purple silhouettes well from below when fish look up at the sky. Long-range boats running multi-day trips to the bluefin grounds put cedar plugs out every morning for a reason. Carry a dozen minimum — you’ll lose some to big fish, and a tuna doesn’t care that the finish is scratched.
Feather Jigs (Zuker / Tuna Feathers)
Feathers are built for reaction strikes — the bubble trail at trolling speed triggers tuna that aren’t actively feeding to bite anyway. This matters on bluefin specifically because they frequently go through lockdown phases where they’re present on the meter but refusing bait. A feather at speed looks like a fleeing baitfish and bypasses that lockdown instinct. Run a tuna spread longer than you would for dorado: two short positions at 30–50 feet, two long at 80–120 feet, and for bluefin add a fifth at 150+ feet for extra standoff distance. Blue/white, black/purple, and green/yellow are the top tuna colors — blue/white for clear conditions, black/purple for dawn and overcast, green/yellow when yellowfin are mixed in. Use 7/0–9/0 J hooks — larger than you’d need for dorado — and sharpen them before every trip. A dull trolling hook at 7 knots produces bumps instead of hookups. When skipjack or bonito crash a feather, don’t just reel it in — tuna are frequently following underneath, and that species activity is a signal to drop down or slow down and investigate.
Rapala X-Rap Magnum Series
Bluefin and yellowfin spend a significant portion of the day below the thermocline — below the 10–15 foot layer where cedar plugs and feathers are working. When you’re getting meter marks but not connecting on the troll, the X-Rap Magnum is the fix. At 10–20 feet of dive depth, it reaches fish that are present but holding below the surface zone. Cautious bluefin are also more willing to commit at depth than at the surface — the lure is farther from the boat’s noise and disturbance, and below the thermocline they’re more relaxed and feeding freely. Run the X-Rap on the outside or long positions of your spread at 5–7 knots, slightly slower than your feathers and plugs. The 15 and 20 sizes cover most SoCal depths. Bonito, sardine, and pilchard patterns work best on tuna. At $20–30 each they’re more expensive than cedar plugs — losing one to a big bluefin stings — but on days when everything else is getting ignored, the X-Rap is often the only thing in the spread getting bit.
Casting Lures
When tuna are on the surface — crashing bait, boiling, or chasing foamers — casting lures is how you get the most explosive strikes in SoCal fishing. The window is often short: tuna push bait to the surface, blow up on it for a few minutes, then go back down. You need to be rigged and ready to cast the moment you see the boil. Speed matters — the first lure in the water is the one that gets bit. For a deep dive on casting technique, see our surface iron guide and jigs vs irons vs poppers comparison.
Surface Iron (Tady 45 / Tady 4/0)
Surface iron is the SoCal standard for tuna on top. When bluefin or yellowfin are crashing bait, a long cast with a Tady 45 (2.9 oz) into the boil and a fast, high-speed retrieve is the play. The iron skips across the surface like a fleeing baitfish, and the flash draws strikes from fish already in a feeding frenzy. The heavier Tady 45 gets maximum casting distance — critical when you’re trying to reach a boil before it goes down. The lighter Tady 4/0 (2.6 oz) gives you a slightly slower, more erratic action that can trigger bites when fish are pickier. Critical upgrade: replace the factory trebles with Owner ST-66 trebles in 2/0–3/0 — factory hooks straighten on tuna instantly. For a complete breakdown, see our tuna jigs and irons guide.
Poppers
A tuna eating a popper off the surface is one of the most violent strikes in fishing — the kind of eat that makes your hands shake. Poppers create a commotion on top that imitates panicked bait, and tuna in feeding mode can’t resist it. For bluefin and yellowfin, you need heavy-duty poppers — 120–180mm in the 2–4 oz range — because these fish pull hard enough to straighten light-tackle popper hooks and break cheap split rings. Nomad Chug Norris and Yo-Zuri Bull Pop are both proven SoCal tuna poppers. Replace the stock trebles with Owner ST-66s immediately. Work them with aggressive pops — two to three hard rod sweeps, pause, repeat. The pause is often when the fish commits. Sardine, bone, and blue/white patterns are the top producers in SoCal clear water.
Big Hammer Swimbaits
A 5–7 inch soft plastic swimbait on a 1–2 oz jig head won’t be the first thing you throw at tuna — but it can be deadly in specific situations. When tuna are feeding on small bait (sardines, anchovies) and refusing larger iron and poppers, a swimbait matching the bait size gets bit. Cast it into the zone, let it sink to the depth the fish are holding, and retrieve with a moderate, steady pace — the swimming tail does the work. Sardine, blue/white, and mackerel patterns in 5–6 inch sizes match the most common SoCal tuna forage. The downside is durability — tuna teeth shred soft plastics fast, and you’ll go through multiple baits per fish. Pack a full bag of 20+. The upside is a natural presentation that can fool line-shy bluefin that have seen every iron jig on the boat. See our swimbaits guide for rigging details.
Dr Fish Casting Spoons
A heavy casting spoon (3–4 oz) in chrome or blue/chrome produces massive flash that tuna can see from a distance. Particularly effective when fish are scattered and you need to draw them to the boat, or when they’re feeding just below the surface and ignoring topwater presentations. Cast it out, let it flutter down 10–20 feet, then retrieve with a pump-and-wind action. The fluttering fall is the key — it imitates a wounded baitfish sinking, and tuna often eat on the drop before you even start your retrieve. Chrome is the go-to in clear water; blue/chrome and green/chrome work in slightly dirtier conditions. Spoons also produce well when jigged vertically under the boat when tuna are holding deep on the meter but won’t come up to the surface.
Color Selection
Tuna are more selective about color than most SoCal species — especially bluefin in clear water. Match the bait they’re eating and you’ll get bit. The top producers:
- Blue and white — sardine imitation, the universal SoCal tuna color. If you only carry one color, this is it.
- Chrome / silver — maximum flash in clear water. Deadly on surface iron and spoons when tuna are chasing bait on top.
- Black and purple — the classic long-range trolling color. Silhouettes well against the sky from below, which is how tuna see trolling lures.
- Sardine / natural — realistic finishes for clear water and picky fish. Top choice for hard-body trolling lures like the Rapala X-Rap.
- Green and yellow — dorado color that also catches yellowfin. Works best in warmer, slightly off-color water south toward Baja.
- Bone / white — clean, subtle profile for bright days in clear water. Excellent on poppers and surface iron.
When in doubt, start with blue/white for casting and black/purple for trolling. Bluefin in particular key on matching the forage — if they’re eating sardines, blue/white and chrome dominate. If they’re on squid at night, darker colors (black/purple, root beer) produce better at dawn. Check the chlorophyll map for water clarity — in cleaner blue water, go natural or chrome. In greener water near upwelling zones, brighter colors get more attention.
When to Throw What
| Situation | Lure Type | Top Pick |
|---|---|---|
| Searching for fish / covering ground | Trolling spread | Cedar plugs + feathers |
| Fish on the meter but not on top | Deep-diving troller | Rapala X-Rap Magnum |
| Tuna boiling / crashing bait on surface | Surface iron | Tady 45 — long cast, high-speed retrieve |
| Fish blowing up on top, staying up | Popper | 120–180mm popper, bone or blue/white |
| Fish feeding on small bait, refusing iron | Soft plastic swimbait | 5–6″ paddle tail, sardine pattern |
| Fish holding deep, scattered | Casting spoon | 3–4 oz chrome spoon, flutter and jig |
| Picky bluefin, clear water | Light casting jig | Tady 4/0 (2.6 oz) chrome or bone |
Working a Tuna Stop
When the captain calls a stop — whether from a troll strike, meter marks, or a visual on foamers — how the boat fishes the stop determines whether you catch a few or load up. Here’s the playbook:
- Be rigged and ready before the stop. Have your iron or popper rod in hand with the bail open before the boat gets to the fish. The first 30 seconds of a stop are the most productive — tuna that are already feeding will eat the first thing they see.
- Match what’s happening on the surface. If fish are boiling, throw iron or poppers. If they’re deep on the meter, drop a spoon or swimbait. If bait is in the water, match the bait size with your artificial.
- Speed sells on surface fish. When tuna are up and eating, retrieve as fast as you can crank. They’re keyed on fleeing bait — slow lures get ignored. Burn the iron back and don’t stop reeling until the jig is at the boat.
- Keep lures in the water. Dead time between casts means the school moves. Reel in, cast again immediately. If you’re fighting a fish, someone else should be casting.
- Downsize if they’re picky. If tuna are boiling but refusing the Tady 45, drop to the lighter Tady 4/0 or switch to a swimbait. Bluefin in particular get lure-shy after seeing the same jig from every angler on the boat.
- Don’t forget the chum. Toss handfuls of sardines or anchovies while casting to keep the school interested. The combination of live chum and a lure swimming through it is hard for any tuna to resist.
Gear for Tuna
Tuna require heavier gear than dorado or yellowtail — especially SoCal bluefin, which regularly run 30–80 lbs with fish over 100 lbs every season. Undersized gear means pulled hooks, broken line, and lost fish.
Casting / iron setup: A spinning reel in the 6000–10000 class — Shimano Saragosa 6000 or Saragosa 8000 — on an 8-foot heavy rod. Spool with 50–65lb braid and a 30–40lb fluorocarbon leader connected with an FG knot. This is your iron and popper rod — it needs backbone to launch a 3 oz jig and stopping power to turn a bluefin before it spools you.
Trolling setup: A 30–50lb class conventional reel — Shimano Talica 12 or Penn Squall II 25N — on a 7-foot medium-heavy rod. Spool with 50–65lb braid or 40lb mono. Set the drag at strike around 12–15 lbs for bluefin — light enough to prevent pulled hooks on the initial run but firm enough to stop the fish eventually.
Hooks: Owner ST-66 trebles on every iron jig and popper — non-negotiable. Factory trebles will straighten on tuna. Pre-rigged J hooks on trolling feathers and cedar plugs. For live bait between lure sessions, Owner Mutu Light Circle (5114) in 2/0–4/0 for fly-lining. See our hooks guide for specific sizes by species and technique.

Frequently Asked Questions
What is the best all-around lure for tuna?
For trolling: cedar plugs — they’ve caught more tuna than any other artificial lure and they cost a few dollars each. For casting: a Tady 45 surface iron in blue/white or chrome with Owner ST-66 trebles. If you could only bring two lure types on a tuna trip, those would be them.
What color lure is best for tuna?
Blue and white is the #1 tuna color in SoCal — it imitates sardines, which are the primary forage. Chrome and silver are close behind for surface iron and spoons. For trolling, black and purple silhouettes well from below. Match the bait the fish are eating and you’ll get bit more consistently.
How do I find tuna in SoCal?
Start with the SST chart — bluefin want 60–72°F, yellowfin want 68°F+. Look for temperature breaks where warm and cool water meet — bait stacks up along these edges and tuna patrol them. The chlorophyll map shows bait concentrations, and the fleet tracker shows where boats are finding fish. Read our bluefin temperature guide and yellowfin temperature guide for seasonal patterns.
Can I use the same lures for bluefin and yellowfin?
Yes — surface irons, poppers, cedar plugs, and feathers all work on both species. The main difference is bluefin are more line-shy, so you may need longer trolling leads, lighter fluoro, and more natural color patterns. Yellowfin are more forgiving — brighter colors and shorter leads still get bit. Gear-wise, size up for bluefin since they average larger and pull significantly harder.
What rod and reel do I need for tuna?
For casting iron and poppers: Saragosa 6000 or 8000 on an 8-foot heavy rod with 50–65lb braid. For trolling: Talica 12 or Squall II 25N on a 7-foot medium-heavy rod. Tuna require heavier gear than dorado — a 40lb class setup is the minimum for SoCal bluefin. See our bluefin reel guide for complete recommendations.
What water temperature do tuna need?
Bluefin: 60–72°F, with the sweet spot around 62–68°F in SoCal. Yellowfin: 68°F and above, with the sweet spot around 72–78°F. Check our bluefin temperature guide, yellowfin temperature guide, and the SST chart to find productive water.
Do I need to replace treble hooks on my lures?
Absolutely — this is the single most important thing you can do before a tuna trip. Factory trebles on iron jigs and poppers are made from soft wire that straightens instantly on a hard-pulling tuna. Replace every treble with Owner ST-66 trebles — 4X strong construction that won’t bend or break. Takes 2 minutes per lure with split-ring pliers. See our hooks guide for the right treble size for each jig.
