Fluke pay off in the bay, bass push to the dark hours as July heat settles in

We're officially into the grind-it-out part of the summer. Last week the bay sat under that hazy July sky, wind mostly light out of the south and southwest in the afternoons, which is exactly the kind of pattern that lets the shallow flats bake. Water in the back bay — Grassy Bay, the flats off Ruffle Bar, the JFK side — has been noticeably warmer than the main channel, and that temperature split is dictating where everything's holding. Bigger tides have been running through the week, pushing good current under the Marine Parkway and Cross Bay bridges, and that current is the difference between a dead afternoon and a solid bite window. As we roll through this week the moon's building toward the next full phase, which means the swings get bigger before they ease off — expect stronger flow at the bridges and inlet, shorter true slack windows, and fish bunching up tighter to structure to save energy against the push.

What that means practically: the bite windows are compressing into the edges of the day. Dawn and dusk are where the quality has been, and the middle of the day has gotten tougher as the sun climbs and that shallow water heats up fast. I'm not going to sell you on a blazing hot bite across the board this week — it's been a mixed week, good in spots, quiet in others, and you have to move to find it.

Stripers are still around but they've gone nocturnal on us in the bay proper. The better fish have been coming off the Marine Parkway Bridge on the last two hours of the outgoing, right in that seam where the current pulls off the fenders into deeper water — 15 to 20 feet under the span. Bucktails in white or chartreuse, 1 to 1.5 ounce, tipped with a strip of squid, worked slow along bottom, have out-produced everything else there. A few guys drifting live bunker on a fish-finder rig through that same stretch at first light have had better luck with size — one report of a fish pushing 30 inches on a snagged bunker fished just off bottom. Outside at Breezy Point and along the Rockaway surf, the bass have mostly been a dawn-patrol proposition. Wading guys throwing darters and needlefish in the dark hour before sunrise have had some quality, but once the sun's up and that surf water warms, it shuts down fast. If you want stripers this week, set your alarm — this isn't an afternoon fish right now.

Fluke are the more consistent story. The bay drift has been paying off nicely in 12 to 20 feet off the Cross Bay Bridge flats and down through the channel edges toward Beach Channel. Four to five inch white and chartreuse Gulp Swimming Mullets on 3/4-ounce bucktails, dragged slow on the drift with the outgoing, have been the go-to. Fish are running mostly 16 to 19 inches with a few keepers mixed in over 20 — nothing giant, but steady enough that a couple hours of drifting will put fish in the cooler if you keep moving and don't marry one drift too long. Live killies and spearing on a standard fluke rig, fished tight to the bottom in the deeper holes off Ruffle Bar, have also been worth the extra bait money.

Bluefish have shown up in fits and starts along the Rockaway surf, mostly in the early morning blitzes that don't last long — fifteen, twenty minutes of chopper blues tearing into whatever's left of the bait pods, then gone. Metal — a Deadly Dick or a Kastmaster — thrown fast and worked through the wash has been the play when they show. You have to be out there watching the water, because by the time you hear about it from someone else on the beach, it's usually over.

Porgies have been steady but unspectacular off Canarsie Pier and the deeper holes near the Bridge — small hooks, clam or worm, patience required, decent for a family trip but not a numbers bonanza right now. Weakfish have been a whisper more than a bite — a few caught incidentally by fluke guys on bucktails in the channel, nothing you can plan a trip around yet. Blackfish are off-season here through the summer, so leave that rod home.

Looking ahead, the bigger tides tied to the building moon should keep pushing good current through the bridges into the weekend, which favors the dawn and late-day bass bite holding pattern. If the wind stays out of the south and light like it has been, I'd expect the back bay to keep warming and push the fluke bite a little deeper as fish look for cooler water — watch the channel edges over the flats rather than the flats themselves as the week goes on. My plan for the next few days: first light at the Marine Parkway seam for bass, then swing into the bay for a fluke drift once the sun's up and the current's still moving well on the tail of the outgoing. If the bluefish show again at Rockaway, that's a bonus stop, not the main event. It's a week where showing up at the right hour matters more than anything else — fish the edges of the day and you've got a real shot; fish the heat of the afternoon and you're mostly just getting a tan.
