Yellowfin Tuna Fishing in Los Sueños
A yellowfin tuna fishing charter in Los Suenos is an offshore sportfishing trip targeting one of the most powerful and prized pelagic fish in the Pacific Ocean. Yellowfin tuna (Thunnus albacares) — also called ahi — range from 30-pound school fish to 200-pound-plus cow tuna at the deepwater FADs (Fish Aggregating Devices) 70 to 140 miles offshore. They don't jump. They circle. And they pull harder, longer, and deeper than almost anything else we chase out of Los Suenos Marina.
Dream Boats CR runs yellowfin tuna charters in Los Suenos year-round from Herradura Bay on Costa Rica's Central Pacific coast. Tuna are available offshore every month, with the strongest numbers from June through September when warm blue water pushes north along the continental shelf. For trophy cow tuna over 100 pounds, multi-day FAD expeditions from May through October put you in range of fish that will test every angler on the boat.
Best Season for Yellowfin Tuna in Los Suenos
Peak season runs from June through September, when warm blue water from the west drives large schools of yellowfin along the continental shelf edge 22 to 35 miles offshore. During these months, standard full-day charters regularly encounter mixed schools of tuna, dorado, and wahoo in the same offshore zone.
For cow tuna, the FAD fishery is the target. The FADs are permanent buoy systems moored 70 to 140 miles from Los Suenos Marina, maintained by INCOPESCA and the Costa Rican fishing cooperative. These structures attract massive concentrations of baitfish, which draw large yellowfin, big-eye tuna, wahoo, and dorado. Multi-day trips departing overnight reach the FADs at first light, when surface feeding activity peaks.
Year-Round Access Other Destinations Can't Match
Most top yellowfin fisheries in the world have a window: 6 to 8 weeks when conditions align, then it's over. Los Suenos fishes tuna all 12 months. The Central Pacific's nutrient-rich Humboldt Current influence, consistent bait concentrations, and a network of FADs deployed 70 to 140 miles offshore create a fishery that doesn't shut down when the calendar turns.
Other destinations charge premium prices for a narrow window. Dream Boats CR departs Los Suenos Marina year-round. School tuna are available on standard full-day offshore runs. Cow tuna over 100 pounds are accessible on multi-day FAD trips throughout the prime May-through-October window.
Why Los Suenos Is One of the Best Places to Catch Yellowfin Tuna
The Spinner Dolphin Signal — Captain Knowledge You Won't Read Anywhere Else
In the Pacific offshore zone, yellowfin tuna and spinner dolphins share the same food source. Tuna and dolphins both feed on the same baitfish schools. When bait gets pushed to the surface, you see spinner dolphins in the air first.
Our captains watch for spinner dolphin pods from the bridge and run toward active aerial activity. Below those spinning dolphins, there are almost always yellowfin. This visual reading of the offshore environment is what separates captains with 20 years in these waters from GPS coordinates and lucky guesses. It's also why experienced anglers who've fished these waters before specifically request a captain who knows the dolphin-tuna connection.
Heavy Tackle and Deep Fights for FAD Cow Tuna
Cow tuna at the FADs require a different approach. These are 100 to 250-pound fish in 600 to 1,200 feet of water. The fight is not on the surface — it's 300 feet down, circling, pulling line off a stand-up rod for 45 minutes to an hour on a single fish.
Our FAD setup uses 80-wide and 130-wide reels loaded with 130-pound monofilament, rigged with circle hooks and heavy-duty swivels. Circle hooks are mandatory under INCOPESCA regulations and are also the right call for deep tuna — they produce higher hookup retention rates on fish that circle and change direction during the fight.
A multi-day FAD trip is not a relaxing offshore cruise. It is one of the most physically demanding fishing experiences available in Central America. If you're targeting a personal best tuna and you're willing to do the work, we'll put you on the right water.
High-Speed Trolling for School Tuna
School yellowfin (30 to 80 pounds) are found along current edges and temperature breaks 22 to 35 miles offshore. Our crew trolls a spread of cedar plugs, jet heads, and rigged ballyhoo at 8 to 12 knots — faster than dorado trolling, slower than wahoo speeds. The goal is to cover water quickly until we mark fish on the sonar or locate surface activity.
When tuna are found balling bait near the surface, we switch from trolling to live bait. Our crew deploys live sardines or mackerel on circle hooks, freelines and flat lines from the stern. Active schooling tuna in feeding mode will strike anything moving near the bait ball, producing fast, multiple-hookup action.
How We Target Yellowfin Tuna on Dream Boats CR Charters
Yellowfin respond differently based on depth, school size, and whether you're fishing nearshore edges or deep FADs. Our captains match the technique to the target.
Yellowfin Tuna vs. Other Offshore Species in Los Suenos
Yellowfin are one of several high-value offshore targets out of Los Suenos. Here's how they compare.
Unlike billfish (catch and release only under Costa Rica law), yellowfin tuna can be kept. Our crew bleeds and ices every fish immediately at boatside to preserve sashimi-grade quality. Local restaurants in Herradura and Jaco will prepare your catch for dinner the same evening. If you want to bring fish home, we pack fillets for travel on request.
Hook to Table — Handling Sashimi-Grade Tuna
The difference between good tuna and great tuna is what happens in the first five minutes after the fish comes over the gunnel. Our crew bleeds every fish immediately by cutting the gill arch, then packs it in an ice slurry to bring the core temperature down fast. This preserves the deep red color and firm texture that make yellowfin tuna worth eating raw.
When you get to the dock, your fish is filleted on the spot. Take the fillets to any restaurant in Herradura or Jaco and they'll prepare them as sashimi, poke, seared ahi, or grilled with garlic butter. This hook-to-table experience is what separates a tuna trip from every other offshore charter.
What the Fight Actually
Feels Like
Yellowfin don't jump. That's the first thing experienced anglers notice. Sailfish tail-walk, dorado cartwheel, marlin go airborne. Yellowfin go down. They circle in wide arcs 200 to 400 feet below the surface, using their weight and the hydrodynamics of that broad, streamlined body to resist every pump of the rod.
A 60-pound yellowfin will tire most first-time offshore anglers before it comes to color. A 150-pound cow tuna at the FAD will test everyone on the boat. The fight is measured in pump-and-crank cycles, lower back endurance, and mental patience. There's no dramatic aerial display to break the tension — just the drag screaming and the line angle telling you how far down the fish is circling. When you finally get color on a cow tuna and see that broad yellow-finned body below the surface, it's a moment every serious angler remembers.
What to Expect on a Yellowfin Tuna Fishing Trip
2026 Season Update: Yellowfin Tuna in Los Suenos
We're heading into the transition period from dry season to green season, and offshore conditions are building well. Scattered yellowfin have been showing up on full-day offshore charters, with school fish in the 30-60 pound range hitting trolled lures and live bait along current edges 25 to 35 miles out.
As water temperatures rise through May and June and the first green season rains begin, expect tuna numbers to increase significantly. FAD reports from the regional fleet indicate good populations of both yellowfin and big-eye at the offshore buoys. Multi-day FAD trips from June through September are booking now — if you want a shot at cow tuna this season, locking in your date early is the move.

Frequently Asked Questions
Yellowfin tuna are available year-round from Los Suenos Marina, with peak season from June through September when warm blue water pushes large schools along the continental shelf edge. For cow tuna over 100 pounds at the offshore FADs, May through October produces the strongest results. School tuna in the 30-80 pound range are accessible on standard full-day offshore charters throughout the year.
A standard full-day offshore charter runs 22 to 35 miles from Los Suenos and targets school yellowfin (30 to 80 pounds) along current edges and bait concentrations. A FAD trip is a multi-day expedition running 70 to 140 miles offshore to permanent fish aggregating devices maintained by INCOPESCA. FAD trips target cow tuna (100 to 250 pounds), require overnight travel, and involve significantly heavier tackle and longer individual fights.
Yellowfin tuna is sashimi grade when handled correctly. Our crew bleeds every fish immediately after landing and packs it in an ice slurry to preserve quality. The result is the same deep red, firm-textured ahi you find at high-end restaurants. Local restaurants in Herradura and Jaco will prepare your catch as sashimi, poke, seared ahi, or grilled. The hook-to-table experience on a tuna trip is one of the best meals you'll have in Costa Rica.
Full-day offshore tuna charters from Los Suenos vary based on boat and group size. Dream Boats CR trips include all tackle, bait, food, drinks, and crew. Multi-day FAD trips are priced separately based on duration and logistics. Contact us for current rates and to discuss whether a standard offshore trip or a FAD expedition best fits your goals and budget.
Yes. Costa Rica requires a fishing license for all anglers, including non-residents fishing on sport charter boats. INCOPESCA tourist fishing licenses cost $15 per week or $30 per month. Dream Boats CR handles license procurement for all charter guests as part of the trip booking process. The license covers all species targeted during your trip, including tuna, dorado, wahoo, and billfish.
Yes. Offshore tuna trips from Los Suenos regularly encounter dorado, wahoo, and billfish in the same water. June through September offshore runs frequently produce mixed bags of yellowfin tuna, mahi-mahi, and wahoo on the same outing. If a sailfish or marlin shows up on the spread, we'll always take that bite — billfish are catch and release only under Costa Rica law, but the fight is one of the best in offshore fishing..
School tuna in the 30-60 pound range are manageable for most anglers with basic offshore experience. Cow tuna at the FADs — fish over 100 pounds — are a different category. Expect 30 to 90 minutes per fish, standing at the rod in a fighting harness, pumping and cranking against sustained deep pressure. It is one of the most physically demanding fishing experiences in Central America. Our crew coaches every angler through proper technique to avoid injury and maximize stamina.
