Yellowfin tuna combine speed, strength and endurance in a way few offshore fish can match. Once hooked, a tuna can make powerful runs and settle into a deep, stubborn fight below the boat.
Costa Rica’s Central Pacific offers yellowfin opportunities throughout the year, with particularly good tuna fishing often occurring during the green season from May through October.
Tuna commonly travel with bait, birds and certain dolphin schools. When the captain finds the right combination of activity on the surface, the fishing can change very quickly.

Yellowfin Tuna Season in Costa Rica
Tuna can appear throughout the year. Water conditions, bait, currents and dolphin activity are often more important than a single calendar date.
Tuna remain possible offshore while sailfish are a major focus of the Central Pacific fishery.
Tuna opportunities often become increasingly important as the offshore seasonal mix begins changing.
The green season can provide excellent yellowfin opportunities, together with mahi-mahi and marlin.
Tuna remain part of the offshore mix as Costa Rica transitions back toward peak sailfish season.
Look for Dolphins, Birds and Bait
Yellowfin tuna are mobile predators. Finding them often means reading everything happening above and below the surface rather than simply heading to one fixed fishing spot.
Costa Rica tuna are frequently associated with active dolphin schools, especially when birds are also working bait around the same area.
Certain active dolphin schools can be an important indicator that yellowfin tuna may be feeding below or around them.
Birds feeding aggressively often indicate bait being pushed toward the surface by predators below.
Breaking tuna, flying fish and nervous bait can help the crew quickly identify an active feeding zone.
Yellowfin Tuna Fishing Techniques
The best technique can change quickly depending on the size of the fish, how they are feeding and what bait is available.
Presenting a lively bait near actively feeding tuna can be one of the most exciting and effective approaches.
Casting a large surface popper toward feeding tuna can produce explosive visual strikes.
Vertical and butterfly jigs can reach tuna feeding below the surface when fish are not staying on top.
Cedar plugs and small offshore lures can be particularly effective for smaller and medium-size tuna.
Real Offshore Fishing
Yellowfin fishing can range from fast surface action to long, determined battles directly below the boat.

Tuna at the Boat
The Fight Usually Gets Harder Near the Boat
Yellowfin are built for speed. The first run can be explosive, but experienced tuna anglers know that the hardest part of the fight can come later.
As the fish gets below the boat it may begin swimming in deep circles. The angler has to maintain pressure and slowly gain line until the crew can bring the tuna alongside.
More Than Just Another Offshore Fish
Yellowfin are among the strongest gamefish pound for pound that you can encounter offshore.
Poppers and live bait can create aggressive strikes that happen right in front of the angler.
Yellowfin is highly prized as fresh seafood and is one of the offshore species anglers may retain when appropriate.
Tuna fishing can occur on the same offshore day as mahi, marlin or sailfish opportunities.
What Boat Is Best for Tuna Fishing?
Yellowfin can be caught from several boat sizes. For offshore tuna, speed, range, fishing space and your group’s desired comfort are usually more important than simply choosing the biggest yacht.

Common Questions
When is the best time for yellowfin tuna in Costa Rica?
Yellowfin tuna can be encountered throughout the year. The green-season months, particularly from roughly May through October, often provide strong opportunities along Costa Rica’s Central Pacific.
How big are yellowfin tuna in Costa Rica?
Fish in the 20- to 100-pound range are commonly discussed in Costa Rica fishing reports and much larger yellowfin are possible. Actual size varies significantly from trip to trip.
Why do you look for dolphins when tuna fishing?
Certain dolphin schools can travel in the same areas as feeding yellowfin. When active dolphins, diving birds and bait are together, the captain may investigate the area for tuna.
Do you troll for yellowfin tuna?
Yes. Cedar plugs and other small offshore lures can be used, particularly for smaller and medium-size tuna.
Can we catch tuna on poppers?
Yes. When yellowfin are feeding near the surface, casting poppers on spinning tackle can produce very exciting strikes.
Do you use live bait for tuna?
Yes. Live bait can be very effective when tuna are actively feeding around dolphin schools, bait concentrations or surface activity.
Can we keep yellowfin tuna?
Yellowfin tuna are an edible pelagic species and may generally be retained subject to current regulations and the captain’s guidance. Your crew can clean the fish you plan to keep.
Is tuna fishing good for beginners?
Yes. The captain and mate can assist with the tackle and fighting technique. Be prepared, however: even moderate-size yellowfin are very strong fish.
Should I book a full day for tuna?
A full day is usually the better option when yellowfin is your primary target because tuna schools move and the captain may need additional range to locate them.
