New moon springs load up the Hook — stripers on the sunset flood, fluke bail out of the bay

Last week the bay did what July bays do — it cooked. Raritan Bay proper sat warm and slack for stretches, especially on the afternoon high stands when there was barely a breath of wind to push any exchange through. That kind of stagnant, sun-baked water doesn't hold fluke like it does in May and June. It pushes them out. By the middle of the week I was hearing the same thing from three different guys at the ramp in Belford and at the Highlands marinas: the flats fish were gone. Not dead, gone — slid out through Chapel Hill and Sandy Hook Channel toward cleaner, cooler water on the ocean side. That's not a bad thing. It's just a different program, and if you were still soaking Gulp on the Flats this week wondering where everybody went, that's why.

This week the moon is the story. We're building into new moon springs, peaking July 11-13, and that means bigger tidal ranges than we've seen since the last full moon cycle — more water moving, faster, through the Chapel Hill and Sandy Hook Channels, over Flynn's Knoll, around Romer Shoal. The current lane sharpens, bait gets funneled harder against structure, and predators stack on the edges instead of spreading out. The other piece that matters: the PM flood is now lining up with sunset. That's the window that reopened this weekend for the first time since June's full moon, and it's the single best low-light bite window of the summer stretch when it works. High water meeting last light at the Rip at the Hook or off Romer is when the bass that have been sulking deep all day come up and feed hard for forty-five minutes to an hour. I'd plan around that tide, not around the clock.

Stripers: the bite has been real but it's a window fish right now, not an all-day fish. Guys working the Rip at the Hook on the last two hours of the flood into the top of the tide, right at dusk, have been putting bass in the 26 to 34 inch range in the boat on bunker chunks fished on fish-finder rigs in 15 to 25 feet, and on white bucktails with a curl-tail trailer worked slow along the rip line where the current folds back on itself. Flynn's Knoll has been more of a sunrise spot this week — the same tide logic in reverse, outgoing water meeting first light, bass working the edges where the Knoll drops into deeper water. Romer Shoal has given up some fish on live eels drifted along the rocks on the last of the ebb, but it's been hit or miss — two solid fish one evening, a skunk the next. That inconsistency is normal for this time of year in the bay proper; the real, reliable window is that sunset flood convergence, and with springs building through the weekend it should sharpen up, not fade.

Fluke: this is where the story changed hard. With bay water running warm and soft, the better fish have relocated into the channels and out toward the ocean side of the Hook, where upwelled water is running noticeably cooler and cleaner. That temperature break is doing the work for you — bait gets pushed and held against it, and the doormats follow. Sandy Hook Channel and the edges of Ambrose have been the better bets, working 4-inch white or pink Gulp Swimming Mullets on 3/4 to 1-ounce bucktails, dragged slow on the outgoing, right along the channel edges where the drop-off meets the flat. A doormat over 12 pounds crossed the scale at a Bayonne shop a few weeks back off this same channel system, and while a fish like that is the exception, it tells you the class of fish moving through when the conditions align. Keeper-size fluke, 19 to 22 inches, have been coming steadier than that, mixed with plenty of short fish you'll have to sort through — bring patience and expect to cull.

Bluefish have been the most dependable thing in the bay this week, honestly. Choppers in the 3 to 6 pound range are blitzing bunker schools inside Raritan Bay off Keyport and Union Beach on calm mornings, visible from a half mile off when they're up on top. Diamond jigs, no bait needed, worked with a fast retrieve through the melee — that's about as simple as fishing gets right now, and it's produced when everything else has been fussy.

Porgies are stacking on Romer Shoal and Flynn's Knoll in decent numbers on sandworms and clam on light tackle, bottom rigs in 20 to 30 feet — good action if you want steady bites for the kids or just want fish in the cooler without overthinking it. Weakfish, I'll be straight with you, remain a ghost in this system. Warm water alone hasn't brought them back in any real numbers, and I'm not going to pretend otherwise just because the temperature checked a box. If you want to try, the deep bend in the Navesink at dusk is still the spot, but don't build a trip around it.

Looking ahead: if the wind stays out of the southwest and lays down by evening — which is the typical July pattern here — I'd fish the sunset flood at the Rip at the Hook Saturday and Sunday, right through the new moon peak. That's where the tide, the light, and the moon all stack in the same direction. Plan B if the bass don't show: run out to the Sandy Hook Channel edge on the last two hours of the outgoing and drag bucktails for fluke in that cooler water. Between the two, something should be biting.
