Kona is grander country. At least 50 verified 1,000-pound marlin have come off this coast, most of them within sight of land. No long run. No continental shelf. Just a volcano dropping straight into the Pacific.
The Run
There is no run. Boats leave Honokohau Harbor and the bottom falls away almost immediately. Crews have described a quarter-mile run to start fishing, and trolling often begins as soon as the boats clear the harbor.
The water drops to 6,000 feet just a few miles offshore and keeps going. Most of Kona’s 1,000-pound marlin have been caught within 2 to 5 miles of shore.
Captains navigate by landmarks that track the twists of the offshore ledge: Kaiwi Point, Keauhou, Red Hill, Keei, Honaunau, Hookena and Milolii. Fish aggregation buoys anchored off the islands add another target, holding tuna, mahimahi, ono and billfish.
What Bites, When
Every month is blue marlin month. Fish over 1,000 pounds have been caught in every month of the year. The heaviest landings and the most consistent fishing come June through October.
May through September is prime for ahi, the yellowfin tuna. Ahi are caught year-round.
May through September is peak ono, with the run building from the full moon in May.
March through May and September through November are the two mahimahi peaks. The fish are around most of the year.
November through June brings the heaviest striped marlin landings. Spring is best for shortbill spearfish, the hardest piece of a royal billfish slam.
How to Fish It
Kona is the home of heavy-tackle lure trolling for blue marlin. Most boats run lures on 80- and 130-pound tackle. Spread geometry, teasers and a practiced hookup sequence are what convert a raised fish into a hooked one. Our blue marlin trolling spread guide breaks it down.
Ono are the speed play. A fast, wire-ready spread works the ledge and the buoys. Read high-speed wahoo trolling spreads.
Pack for This Port
The charter fleet supplies heavy tackle. Bring the charter day kit: the sun here is brutal, so a sun hoodie, polarized glasses and gloves earn their space. Check charter day essentials too.
Running your own boat? You need serious big-game gear. Compare lever-drag reels in our offshore trolling reels roundup, and start from the blue-water trolling starter kit. A fighting harness and standup rod matter when a fish that size eats.
Before You Go
Check the Hawaii Division of Aquatic Resources for state rules. The Atlantic HMS permit does not apply in Hawaii. Federal waters here fall under the NOAA Fisheries Pacific Islands Region, so check its non-commercial fishing pages for any federal requirements. This is not legal advice.
Deep water close to shore does not mean calm water. Watch the trades, carry safety gear, and file a float plan. The fish don’t negotiate.
