Bonito and Spanish Mackerel Push Into Sandy Hook as Fluke Holds

What's biting

What's next

Look for the current pattern to hold and likely intensify over the next two to three days. Grumpys Tackle (NJ) notes that Spanish mackerel and false albacore are just starting to show, which typically means bigger, more consistent schools work into the inlets and rips around Sandy Hook and Raritan Bay as the week progresses — keep epoxy jigs and small metals rigged and ready for blitzes that can appear and vanish fast.

Fluke fishing should stay steady rather than blow up. Capt Ron's Atlantic Highlands reported a slow start with several unproductive drifts before finding quality fish, a pattern typical once bay water holds in the upper 60s to low 70s — working multiple areas and searching through the tide change remains the key, since Capt Ron's own reports note much better life after the tide turned. Anglers fishing bucktails tipped with strip bait or Gulp should keep grinding through marginal drifts rather than staying put on one spot.

Bluefish should stay aggressive into the weekend. The Fisherman — Northern NJ reports boats like the Golden Eagle mixing slammer-class blues with bonito and Spanish mackerel, and that kind of mixed-bag action tends to hold as bait schools stack up along the beachfront and inlet mouths through late August.

Offshore, expect the tuna bite to stay in play for boats running out of the Highlands and Belmar area. OTW Northern New Jersey's latest report describes yellowfin tuna mixed with midshore bluefin off the beaches and inlets, a combination that typically firms up through late August as offshore water temperatures peak — weekday runs may see less pressure and better shots at the mid-range grounds.

With the moon in First Quarter, expect moderate tidal swings rather than the extremes of a new or full moon, a good window for working structure and rips methodically instead of racing a fast-moving current. Weekend anglers should plan around the morning tide change for the best shot at both the fluke and mackerel bites, and watch for the false-albacore push Grumpys flagged to build through the week as water continues to warm along the beachfront.

Context

Mid-to-late August is the classic transition window for Raritan Bay and Sandy Hook: summer flounder fishing typically holds steady but unspectacular as bay water peaks in the upper 60s to 70s, while the first true influxes of Spanish mackerel, bonito, and false albacore usually arrive on roughly this timeline as baitfish schools of peanut bunker and spearing stack up along the beachfront. Grumpys Tackle (NJ) flagging false albacore "starting to make a showing" alongside Spanish mackerel lines up with a fairly typical seasonal calendar for this stretch of coast — not early, not late.

Bluefish activity described by The Fisherman — Northern NJ, with boats like the Golden Eagle and Miss Belmar Princess putting anglers on slammer-class blues mixed with bonito and mackerel, is also consistent with larger bluefish schools pushing bait against the beach in August before the fall run further concentrates everything in September and October.

The one soft spot in this week's intel is striped bass — none of the available reports from Sandy Hook or Raritan Bay-adjacent sources specifically flagged a striper bite this week, which isn't unusual for mid-August when bass often sit deeper or further offshore until water starts cooling toward the fall run. NJ Fish & Wildlife News' note on the nearby Shark River Access WMA confirms striped bass remain a regular part of the catch mix in this general area, just not this week's headline bite.

No buoy or gauge readings were available this cycle, so this note leans entirely on angler and shop intel rather than logged water-temperature trends.
