Wilmington's warm-water wall holds together — yellowfin and a few whites reward the run

We're a few days off the full moon now, sliding into that waning gibbous phase that always makes me want to fish the pre-dawn bite harder than the midday troll. By midweek we'll be pushing toward last quarter, and that matters out here more than people think — the bigger tidal push around the full moon stirs current through the canyon heads, and as that current eases into the neap stretch, the edges tend to tighten up instead of smearing out across five miles of ocean. Last week the wall held its shape pretty well through the bigger tides, which tells me the eddy sitting on the canyon isn't just a passing feature — it's dug in. That's the good news. The bad news is the same warm water that's held things together has also spread the fish out along a long stretch of structure instead of pinning them to one honey hole, so you're doing some running to connect.

Wind's been the story more than temperature the last ten days. We had a stretch of light southwest breeze that let boats sit out past the 100-fathom curve and actually work the color change without getting bounced around, and that's when the trolling bite came together. This week looks like more of the same to start — light and variable through the weekend, with the usual afternoon sea breeze filling in out of the south. If that holds, Friday and Saturday morning look like your window before it turns sloppier out toward the shelf break by Sunday. Watch the forecast close on that — a stiff southwest wind against the Gulf Stream edge can turn glass into a washing machine in about four hours out here.

As for what's biting: yellowfin have been the backbone of the week, and it's a solid bite, not a stacked one. Boats working the temperature break along the eastern wall of the canyon, roughly out around 38°28'N/74°32'W where the bottom drops from 100 fathoms into the canyon proper, have been picking up yellowfin in the 25 to 45-pound class trolling a mixed spread — green machines and small Ilanders in the pattern, ballyhoo skirted behind the boat, cedar plugs way back in the shotgun. Green-and-yellow and pink-and-white have both worked depending on the day, which tells me the fish aren't locked onto one color as much as they're keying on the edge itself. When the trolling bite goes quiet mid-morning, guys are switching to chunking butterflied bunker over that same break and picking away at fish through the slack tide — not a stacked chunk bite, more of a steady pick, two or three fish over a couple hours if you're patient and keep a clean chum slick going.

White marlin have shown, but it's spotty. A handful of releases came off the northern edge of the canyon where a warmer tongue of water was pushing bait up against the 60-fathom line — that's classic early-July stuff, whites riding the inside edge of the eddy before the core water pushes further offshore later in the month. If you're targeting whites specifically, I'd troll smaller ballyhoo and spreader bars tight to that inshore break rather than running all the way out to the canyon face. Mahi have been mixed in with the yellowfin around any floating structure — a few boats found decent-sized dolphin, some pushing 15 to 20 pounds, holding under scattered sargassum lines drifting off the edge. Nothing consistent enough to call it a mahi bite on its own, but if you're already trolling the break and you see grass, it's worth a pass with a naked ballyhoo or small skirted lure.

Bigeye and wahoo have been quieter this week, and I'll be honest about that instead of dressing it up. The bigeye chunk bite at night needs a cleaner, more settled current than we've had, and with the tide still working through that post-full-moon push, the drift chunk sets weren't holding as tight as I'd like. A couple of night boats got into bigeye around the canyon's deep water, working butterflied bait on 50 to 80-pound circle hooks well back in a dark slick, but it wasn't the kind of consistent bite where I'd tell you to plan a whole trip around it yet. Wahoo have been mostly a bycatch story — a fish here or there on a deep-diving lure run well back in the pattern, nothing to suggest they've set up in numbers.

Looking ahead, if the wind stays light through the weekend like it's shaping up to, I'd run straight for that eastern wall break again and work it top to bottom — troll it early, chunk it through the midday lull, and be ready to switch back to trolling as the afternoon thermocline tightens up the edge. If the sea breeze builds harder than expected by Sunday, I'd rather shift north toward that warmer tongue where the whites have been showing — smaller swells, calmer troll, and a bite that doesn't need glass to work. Either way, the canyon's holding fish right now; you just have to run the wall instead of parking on one number and hoping. That's been the theme all week, and I don't expect it to change much until this moon cycle rolls over.
