June produced exactly the kind of fishing that keeps anglers coming back to Costa Rica year after year.

Yellowfin tuna were plentiful, sailfish continued to light up offshore spreads, and inshore waters delivered steady action for roosterfish, snapper, grouper, and jacks.

But one fish stole the spotlight

.

Fishing aboard Geax Fly, an angler connected with a black marlin estimated at nearly 900 pounds—the kind of fish most fishermen spend a lifetime hoping to encounter. After an unforgettable battle that tested both angler and crew, the fish was successfully released, creating one of the most memorable catches of the season so far.

Combined with productive offshore and inshore conditions throughout June, it was another reminder of why Los Sueños Marina remains one of the world's premier sportfishing destinations.

Key Takeaways

• A rare 900-pound black marlin was successfully released aboard Geax Fly.
• Yellowfin tuna remained one of the most consistent offshore species throughout June.
• Sailfish, blue marlin, striped marlin, and mahi-mahi provided excellent offshore action.
• Roosterfish, snapper, grouper, and jacks highlighted the inshore bite.
• Full-day offshore charters produced the best opportunities for pelagic species.
• Several marina restaurants can prepare your fresh catch after a successful day on the water.

Catch of the Month: A 900-Pound Black Marlin

Every fishing season produces memorable catches.

Very few produce a black marlin approaching 900 pounds.

Heading offshore aboard Geax Fly, the crew was focused on one thing: finding a black marlin.

Patience paid off.

Suddenly, a massive fish appeared behind the spread. The marlin lit up with electric colors, charged the bait, and exploded from the water in a spectacular aerial display that instantly left no doubt about its size.

The fish was estimated at approximately 900 pounds, placing it among the largest black marlin encounters seen in recent memory around Los Sueños.

What followed was a battle that tested everyone on board.

The angler settled into a fight that demanded patience, endurance, and determination. The crew worked flawlessly, adapting to every run and change in direction while the fish used every ounce of its strength.

Black marlin of this size are rare in our waters. Even in a destination known worldwide for billfishing, opportunities to encounter a fish approaching the 1,000-pound mark remain extraordinarily uncommon.

After a hard-earned battle, the fish was brought alongside the boat and successfully released in excellent condition.

The marlin swam away strong.

It's the kind of moment anglers dream about—and one that will undoubtedly be talked about around the marina for years to come.

Offshore Conditions: June Starts Strong

The first half of June delivered exactly the kind of offshore conditions anglers hope for on Costa Rica's Central Pacific Coast.

Current movement, floating debris, bait concentrations, and productive color changes combined to create excellent opportunities for pelagic species.

Boats working these areas found a healthy mix of yellowfin tuna, sailfish, mahi-mahi, blue marlin, and striped marlin throughout the month.

The offshore bite remained dynamic, rewarding crews that stayed mobile and adjusted to changing conditions.

When birds, bait, and dolphins appeared, opportunities often followed shortly afterward.

Offshore Species Report

Yellowfin Tuna

Yellowfin tuna continued to be one of the most reliable species throughout June.

Schools ranged from football-sized fish to triple-digit bruisers capable of testing even experienced anglers.

Many of the most productive days occurred when captains located feeding birds and spinner dolphins, both classic indicators of active tuna schools.

Pacific Sailfish

Sailfish remained a consistent presence offshore.

Boats working productive current lines and water color transitions regularly raised fish, providing exciting opportunities for catch-and-release anglers.

Blue and Striped Marlin

Blue and striped marlin continued to show along the same productive offshore corridors that held tuna and sailfish.

While not every boat encountered marlin, crews putting in full days offshore consistently reported opportunities throughout the month.

Mahi-Mahi (Dorado)

Mahi-mahi remained a welcome addition to many offshore trips.

Floating debris and current lines continued to attract fish, providing both exciting action and excellent table fare for anglers choosing to keep legal catches.

Offshore Bite Quality

Strong overall.

Many crews reported multiple opportunities during a single day, particularly when they remained focused on active signs of life, including:

• Diving birds
• Spinner dolphins
• Floating debris
• Current breaks
• Water color changes
• Concentrated bait schools

The Techniques Producing Results

The most successful crews combined traditional trolling methods with a willingness to adapt throughout the day.

Captains typically started by covering water with rigged ballyhoo and offshore lures while searching for productive conditions.

Once tuna schools were located, many switched to live bait or surface poppers to maximize opportunities.

Most Productive Methods

• Trolling rigged ballyhoo
• Pulling skirted lures
• Live bait fishing
• Casting poppers to feeding tuna
• Working current lines and debris fields

The ability to adjust techniques based on changing conditions remained one of the biggest factors separating good days from exceptional ones.

Inshore Fishing Remains Productive

While the offshore action grabbed much of the attention in June, the nearshore fishery continued to produce excellent results.

Roosterfish remained one of the most popular targets for visiting anglers.

Fish were active around rocky points, beaches, and current seams, responding particularly well to slow-trolled live baits and carefully worked surface poppers.

Several quality roosterfish were reported throughout the month, reinforcing Costa Rica's reputation as one of the world's best destinations for anglers pursuing this iconic species.

Snapper and Grouper

Boats fishing reefs, rock piles, and deeper structure found productive action for snapper and grouper.

Cubera snapper remained a prized catch, delivering powerful strikes and unforgettable fights around heavy structure.

Jacks and Trevally

Jacks and trevally provided consistent action and aggressive strikes throughout the month.

These hard-fighting fish kept rods bent and added plenty of excitement to inshore trips.

Other Species

Depending on the conditions, anglers also encountered:

• Snook
• Wahoo
• Various snapper species
• Seasonal visitors moving through the area

Ideal for Families and Mixed Groups

Half-day and three-quarter-day charters continued to be a popular option for families and groups looking for steady action without the longer offshore run.

For many visitors, inshore fishing provided the perfect balance between excitement, scenery, and convenience.

From the Water to the Marina Table

One of the most rewarding parts of fishing out of Los Sueños Marina happens after the boat returns to the dock.

Restaurants at the marina can prepare your fresh catch for dinner, turning a successful day on the water into an unforgettable dining experience.

There's something uniquely satisfying about sitting down with family and friends to enjoy fish that was swimming in the Pacific only hours earlier.

For many guests, it's every bit as memorable as the fight itself.

Watching the boats return to the marina while enjoying your own catch is one of those experiences that perfectly captures what a fishing vacation in Los Sueños is all about.

Looking Ahead to July

If June is any indication, anglers can look forward to continued opportunities for yellowfin tuna, sailfish, mahi-mahi, and marlin as the season progresses.

Current lines remain active, bait concentrations continue to attract pelagic species, and the inshore fishery shows no signs of slowing down.

While every day on the water is different, conditions remain favorable heading into July.

And somewhere offshore, another fish of a lifetime may already be waiting.

Plan Your Next Fishing Adventure

Whether you're chasing trophy marlin, searching for your first sailfish, targeting roosterfish along the coastline, or simply hoping to enjoy fresh tuna at the marina after a successful day on the water, June once again demonstrated why Los Sueños remains one of the most respected sportfishing destinations in the world.

From record-worthy billfish to family-friendly inshore action, every trip offers the possibility of an unforgettable story.
