Tuna fishing in Baja runs the full spectrum of Pacific sportfishing — from 20-pound yellowfin tuna caught on light spinning gear within sight of the Coronado Islands to 300-pound bigeye hauled up from the deep on the offshore banks south of Cabo. The species are different, the techniques diverge significantly, and the locations span the entire 1,000-mile peninsula. What they share is the kind of fishing that fills ice chests with the finest eating fish in the Pacific and leaves anglers calculating the soonest possible return trip.
This guide covers all three tuna species found in Baja waters, where and when to find them, and the gear and techniques that produce.
Tuna Species in Baja Waters
Yellowfin Tuna
The most widely distributed and most commonly caught tuna in Baja. Yellowfin appear throughout the Sea of Cortez from summer through fall, with the most consistent action in the La Paz, East Cape, and Cabo areas. They also push north into Pacific waters off the Coronados and San Diego in warm-water years. Average size in Baja: 20–80 pounds, with larger fish on the offshore banks.
Bluefin Tuna
The heavyweight of the tuna world and the primary target of the San Diego long-range fleet. Bluefin move through northern Baja Pacific waters seasonally — sometimes in extraordinary numbers. School fish of 30–80 pounds are most common; larger fish (100–300+ pounds) appear regularly and occasionally produce exceptional trophy fishing. The Coronado Islands area and the offshore banks near San Diego see the most consistent bluefin action in warm-water years.
Bigeye Tuna
The deepest-dwelling and least commonly targeted tuna in Baja. Bigeye prefer deeper, cooler water than yellowfin and are typically encountered on extended offshore trips working canyon structure. Average size exceeds yellowfin. They’re excellent table fish — possibly the best eating tuna available — and a trophy catch on any Baja trip.
Where to Find Tuna in Baja
The Coronado Islands and Northern Baja (Bluefin)
In warm-water years, bluefin tuna move north from Baja into San Diego-area waters, staging around the Coronado Islands and the offshore banks beyond. When this happens the San Diego long-range fleet pivots entirely to bluefin, and the fishing can be extraordinary. The bite is typically available from spring through fall in good years.

La Paz and East Cape (Yellowfin)
The offshore banks south of La Paz produce consistent yellowfin tuna from July through November. Boats run 20–40 miles offshore to find schools staging around temperature breaks and underwater structure. The East Cape similarly provides yellowfin access for anglers at the fishing camps. See the La Paz guide →
Cabo San Lucas (Yellowfin and Bigeye)
The offshore banks beyond Cabo’s “Finger” canyon produce yellowfin tuna year-round and bigeye tuna in deeper water. The Cabo fleet targets tuna as a secondary species alongside marlin and wahoo — dedicated tuna trips require longer runs but are productive for serious anglers. See the Cabo guide →
Tuna Season in Baja
| Species | Season | Peak |
|---|---|---|
| Yellowfin | June–November (south Baja) | August–October |
| Bluefin | April–October (north Baja) | May–August in good years |
| Bigeye | Year-round (deep offshore) | Summer–Fall |
Tuna Gear
Light Tackle (Yellowfin and School Bluefin)
Light-tackle tuna fishing — 30–50lb class gear on spinning or conventional outfits — is the most exciting way to target school yellowfin and smaller bluefin. These fish fight well above their weight class on appropriate tackle.
Shimano Saragosa SW 8000 — a powerful spinning reel with capacity for the long runs tuna make. [IMAGE: spinning reel]
Penn Spinfisher VII 8000 — sealed body, smooth drag, handles 65lb braid capacity for yellowfin. Good value alternative.
Spool with 65lb braid and 40–50lb fluorocarbon leader. Tuna in clear water can be leader-shy — keep the fluorocarbon leader as short as practical (4–6 feet).
Seaguar Blue Label 40lb fluorocarbon
Heavy Tackle (Large Yellowfin and Bluefin)
Large yellowfin over 100 pounds and big bluefin require heavier setups — lever-drag conventionals with 80lb line and fighting belts for extended battles.
Shimano Talica 20 — excellent two-speed reel for large tuna work. The low gear provides power to pump large fish from depth.
Braid Products Fighting Belt — essential for fights with large tuna that may last 45+ minutes. Protects your abdomen and provides rod leverage. [IMAGE: fighting belt]
Tuna Lures and Baits
Cedar Plugs
The simplest and one of the most effective tuna lures ever made. A cedar plug trolled at 8–10 knots produces yellowfin, bluefin, and bigeye across all Baja destinations. Inexpensive, nearly indestructible, and effective in multiple colors.
Cedar Plug Assorted Colors — natural cedar, blue/white, and green/yellow are the most productive Baja colors. [IMAGE: cedar plug lure]
Trolling Feathers
Trolling Feathers Assorted — work at slower trolling speeds than cedar plugs and produce well on yellowfin in particular. Run them in combination with cedar plugs for a mixed spread. [IMAGE: trolling feather lure]
Offshore Jigs
When tuna are visible on the surface or marking on the sounder, vertical jigging produces results that trolling cannot match.
Shimano Butterfly Flat-Fall 200g — a precision offshore jig that flutters on the drop to imitate injured baitfish. Deadly on tuna when worked at the right depth. [IMAGE: Shimano butterfly jig]
Nomad Design Gypsea 200g — an excellent flutter jig for yellowfin and bluefin. The slow-pitch jigging action produces when standard jigging doesn’t.
Surface Iron
When bluefin or yellowfin are crashing bait on the surface, heavy surface iron retrieved at maximum speed produces explosive strikes.
Tady A-1 Surface Iron — the classic San Diego surface iron for tuna. Cast into breaking fish and reel as fast as possible. [IMAGE: Tady A-1]
Live Bait
Live mackerel and sardines are the most effective tuna bait available. Drop a live bait to the depth where tuna are marking and let it swim naturally. Circle hooks reduce deep hooking and facilitate release of smaller fish.
Owner Mutu Light Circle Hooks 3/0–4/0 — standard live bait hook for yellowfin and school bluefin.
Frequently Asked Questions
What is the difference between yellowfin and bluefin tuna in Baja?
Yellowfin are the more common southern Baja species — abundant in the Cortez from summer through fall. Bluefin are the northern Baja species that push into Pacific waters seasonally and are larger on average. Yellowfin are more approachable for most anglers; bluefin fishing attracts dedicated long-range anglers with specialized heavy gear.
How far offshore do I need to go for Baja tuna?
Varies by location and season. In good years, bluefin come within 10–20 miles of the Coronados. Yellowfin south of La Paz typically require 20–40 miles. Bigeye and larger yellowfin may be 60+ miles offshore. Ask your charter captain about current conditions before booking.
Are Baja tuna good eating?
Outstanding — yellowfin and bigeye tuna are among the finest eating fish in the ocean. Fresh sashimi, grilled, seared rare, or canned — the quality far exceeds anything available commercially. Bleed the fish immediately and keep well-iced for best results.
What pound test for yellowfin tuna?
65lb braid with 40lb fluorocarbon leader covers most yellowfin situations in Baja. For large fish over 100 pounds, 80lb braid with 60lb fluorocarbon. For leader-shy fish in clear water, drop to 30lb fluorocarbon on light spinning gear.
What is the bag limit for tuna in Mexico?
10 tuna per angler per day, combined across species (yellowfin, bluefin, bigeye). See our Baja fishing regulations guide.
Do I need long-range gear for Baja tuna?
For day trips targeting school yellowfin near La Paz or Cabo, standard medium-heavy offshore gear is sufficient. For large bluefin or extended offshore trips, heavier two-speed conventional gear (50–80lb class) is appropriate. Talk to your charter captain about gear requirements for your specific trip.
