Power, speed and exceptional table fare make yellowfin tuna one of the most exciting offshore targets near Jacó and Los Sueños. Learn when to go, how the crew finds them and which charter setup fits your group.
Yellowfin tuna (Thunnus albacares) are built for speed. Their streamlined bodies, powerful tails and long yellow finlets allow them to cover open ocean and make deep, sustained runs after the hook-up.
A tuna fight is often less aerial than a sailfish battle but far more demanding below the surface. The fish may circle deep beneath the boat, forcing the angler to maintain steady pressure while the captain and mate keep the line clear.
Tuna size varies widely, and the largest fish are never guaranteed. Even a modest yellowfin can produce an intense fight on appropriate tackle.

How tuna are targeted
Techniques depend on what the fish are doing
A good crew adapts to bait, birds, dolphin activity, current and the depth at which tuna are feeding.
Live Bait
Presenting a lively bait near active tuna can produce decisive bites when fish are feeding close to the surface.
Poppers & Casting
Surface lures create a visual, high-energy strike when tuna are breaking water within casting range.
Vertical Jigging
Metal jigs reach fish holding below visible surface activity or around deeper bait concentrations.
Trolling
Lures or rigged bait can cover water while the crew searches for birds, bait and productive conditions.
Chunking
Small pieces of bait create a controlled trail that may draw tuna closer and keep them around the boat.
Dolphin Association
Yellowfin may travel beneath spotted dolphins. Crews target the tuna while avoiding contact with or harassment of dolphins.
Fishing season
When is the best time for yellowfin tuna?
Yellowfin can appear in Costa Rica’s Pacific waters throughout the year. The Central Pacific often sees stronger and more consistent opportunity from late spring through fall, with additional productive periods possible later in the year.
Ocean conditions do not follow a fixed calendar. Bait, currents, water temperature and moving dolphin schools influence the bite, so the most useful information comes from recent local fishing reports.
Yellowfin tuna are commonly retained for food. Responsible fishing means keeping a reasonable amount, respecting current rules and releasing fish that the group does not need.

Tuna questions
Yellowfin tuna fishing FAQ
Can you catch yellowfin tuna year-round in Jaco?
Yellowfin are possible throughout the year, but abundance and location vary. Late spring through fall often provides stronger opportunity in the Central Pacific, although recent reports matter more than a fixed calendar.
Should we book a half day or full day?
A full day is recommended. Tuna move through offshore water, and the crew may need significant time to locate dolphins, birds, bait or visible feeding activity.
How far offshore are the tuna?
There is no fixed distance. Tuna may be encountered closer or farther depending on currents and bait. Ask for an updated estimate immediately before your trip.
Are yellowfin tuna released?
They can be released, but yellowfin are also legally retained as food when current regulations allow. Selective harvest and careful handling are more accurate conservation guidance than treating tuna like mandatory-release billfish.
Can beginners catch tuna?
Yes. The mate can explain fighting technique and help manage the tackle. Guests should still expect a physically demanding fight, especially with larger fish.
Is catching tuna guaranteed?
No. Tuna are wild, highly mobile fish. A reputable operator can provide suitable equipment and local knowledge but cannot guarantee any species or catch.
