Cape May sits at the bottom of New Jersey, and that geography is a weapon. The southern tip means shorter runs to the canyons, with the whole mid-shore playground in between. Billfish, four tunas, mahi under every pot buoy. There’s no small version of this.

The Run

Mid-shore first. About 15 to 25 miles out, lobster pots, buoys and weed lines hold mahi through the back half of summer. That is small-boat territory with blue-water payoff.

The Lobster Claw is about a 50- to 60-mile run from Cape May and Great Egg inlets. It is ridge structure that pulls bluefin and yellowfin in the summer, with makos and the occasional wahoo in the mix.

Then the edge. Wilmington Canyon sits about 70 nautical miles off southern New Jersey, with yellowfin and bigeye working the 100- to 200-fathom zone. Baltimore and Poor Man’s are also on the menu, and the best canyon action out of Cape May generally starts 80-plus miles out. Marlin crews range north to the Spencer and Lindenkohl area as well. Early season, fish the temperature breaks. Later, when the water blends, chlorophyll edges tell the story.

What Bites, When

May brings the first yellowfin and the first inshore bluefin. June and July are prime for bluefin. The first white marlin of the year usually show in early June.

July turns everything on. Blue marlin bite best July through September. White marlin build through July toward their August peak. Yellowfin settle in on the edge and inshore ridges, and mahi start building.

August is loaded. By late July finding mahi is usually a sure bet, and they hold well into September.

September is the white marlin crescendo. Numbers peak before the season fades.

October keeps bluefin and yellowfin in play when the weather allows.

How to Fish It

Bluefin on the inshore grounds and ridges reward a smart trolling spread and good temperature intel. Our canyon run guide covers SST charts, fuel range and the spread. When the yellowfin are deep and stubborn, stop and chunk. Jigs dropped on marked fish are another way in.

For marlin, discipline wins. Run the spread right and execute the hookup sequence every time with the blue marlin trolling spread guide. Mahi are simple: run the pot lines, find the one with fish under it, and pitch.

Pack for This Port

Start with the blue-water trolling starter kit. A two-speed reel earns its spot for tuna on the edge: see the offshore trolling reels roundup. Pack quality braid, fluorocarbon leader, a few speed jigs, and a real gaff from the boatside tools roundup.

Before You Go

New Jersey requires free saltwater registry enrollment for anglers 16 and up. Check current rules at NJ Fish & Wildlife. Tunas, billfish, swordfish and sharks are federal Highly Migratory Species with their own vessel permit. Bluefin rules change in-season: check the NOAA bluefin status page before you go. Not legal advice.

Canyon runs from Cape May are long. Do the fuel math, carry a reserve, and let the forecast make the call.
