Costa Rica Fishing Company August 4, 2026 ## Quick Answer - Blue marlin are caught off Quepos mainly in the green season, from May through September, with June to August usually the strongest months. They live far offshore in deep blue water, so the best chance comes on a Full-Day or 3/4-Day Offshore charter. Most fish run roughly 200 to 500 lbs, much larger fish are possible, and every marlin is released alive. ## Why Blue Marlin Are the Ultimate Trophy For many offshore anglers, a blue marlin is the fish of a lifetime. It is one of the largest and fastest fish in the ocean, and the first run after the hookup can strip line off the reel at a pace few other species come close to. Hooking one is never routine, which is exactly why it sits at the top of so many bucket lists. Quepos has a real advantage here: deep offshore water lies within charter range of Marina Pez Vela, so you spend less of the day running and more of it fishing the blue water where marlin feed. ## Blue Marlin Season in Quepos Blue marlin are most active off Quepos during the green season, roughly May through September, and June, July and August are usually the strongest months. Warmer water and more bait offshore draw marlin within reach of a day charter, often alongside big schools of yellowfin tuna. Outside that window marlin are still possible on offshore trips, just less consistently. If a marlin is the main goal of your trip, plan around the green season and book as much time offshore as your schedule allows. ![Blue marlin in deep blue water off Quepos, Costa Rica](https://costaricafishingcompany.com/wp-content/uploads/2026/10/costa-rica-fishing-company-43.webp) Blue marlin hunt far offshore in deep blue water, where bait and tuna gather — Costa Rica Fishing Company ## Where Blue Marlin Are Found Off Quepos Blue marlin are a true blue-water species. Captains look for the same signs that hold all offshore predators: temperature breaks, current edges, color changes in the water, birds working bait and schools of tuna. On our Full-Day Offshore charter the productive grounds are typically 20 to 40 miles out, where deep water meets the surface currents. ## How We Target Blue Marlin Trolling is the classic approach: a spread of large lures or rigged baits pulled at speed covers miles of water and draws marlin up from below. When a fish shows behind the spread, the crew works fast to get a bait in front of it. Circle hooks and heavy tackle help land the fish quickly and release it in good condition. ## Size and the Fight Most blue marlin encountered off the Central Pacific run roughly 200 to 500 lbs, and fish of more than 800 lbs have been recorded in these waters. Females grow far larger than males. Expect explosive jumps, long runs and a fight that can last well over an hour — a real test of teamwork between angler, captain and crew. ## Catch and Release: Every Marlin Goes Back Costa Rica's Fishing Law (Law 8436) classifies blue marlin as a species of tourist and sport-fishing interest, and INCOPESCA rules require sport anglers to release billfish alive. On our charters every marlin is released: the crew keeps the fish in the water, removes the hook or cuts the leader close to it, and you get photos boatside before it swims away. ## Which Charter Is Best for Blue Marlin? Our Full-Day Offshore charter (9 hours, 7:00 AM to about 4:00 PM) is the strongest choice for marlin: it gives your captain the most time to reach and work the best water. The 3/4-Day Offshore charter (7 hours, back by 2:00 PM) still reaches blue water and suits anglers who want a shot at marlin with a free afternoon. ## Blue Marlin at a Glance Here are the key facts, at a glance: - Peak season: May–September (green season) - Strongest months: June, July, August - Typical size: about 200–500 lbs, larger fish possible - Best charter: Full-Day or 3/4-Day Offshore - Technique: offshore trolling with lures or rigged baits - Catch policy: 100% catch-and-release More local fishing guides on our partner site: [manuelantoniodeepseafishing.com](https://manuelantoniodeepseafishing.com/) Ready to Book?
