Sea bass carry Raritan Bay while fluke bite goes see-saw

What's biting

What's next

The last several days of captain reports out of Atlantic Highlands show a pattern worth watching: strong mid-week fishing (Tuesday's "top ten day," Wednesday's improved life on the bottom) sandwiched around a slower weekend, per Capt Ron's Atlantic Highlands NJ. If that rhythm holds, the next weekday trips are the better bet for limits, with weekend crowds and pressure likely softening the bite again. Sea bass should keep providing the floor — Capt Ron's has described the bottom as loaded with sea bass on nearly every recent trip, sometimes to the point of beating fluke baits down.

Further south in Belmar, several captains are already talking about the shift toward fall. Skylarker and Ol' Salty II both describe the second half of August as a turning point, with the Skylarker's captain saying "the good fishing is going into overtime in September," and Ol' Salty II noting "it's reasonable to think we will have a good September." Golden Eagle points to sand eels holding in the area as the likely driver of stronger fishing into September. None of these reports are from directly inside Raritan Bay or off Sandy Hook, but they describe the same stretch of north Jersey coast and are a reasonable read on where the season is heading regionally.

Expect the fluke-to-striper handoff to start showing up soon. Miss Belmar Princess's captain has already said he'll switch over to striped bass once fluke season wraps, "if the stripers show up like they did last season" — a signal to watch rather than a confirmed bite yet. Grumpys Tackle's shop reports also flag bonito and Spanish mackerel activity on epoxy jigs while water stays warm, which should continue into the Labor Day weekend before any real cooldown.

No live buoy or gauge data is available for this cycle, so plan tides and current around your own local chart. With the moon in a waning gibbous phase, tidal swings are moderate rather than the extremes you'd see around new or full moon — worth factoring into drift-fishing plans for fluke and sea bass over the next few days. Check local marine forecasts before heading out, since no wind or sky data is available here.

Context

Late August into early September is a well-known transition window on the north Jersey shore, and the reports gathered here are broadly consistent with that: fluke fishing described as "winding down" or getting "tougher" (Capt Ron's Atlantic Highlands NJ), sea bass staying strong on the bottom, and captains starting to talk about striped bass and sand eels as the next act (Miss Belmar Princess, Golden Eagle). NJ Fish & Wildlife News' note on the Shark River Access WMA underscores that this stretch of Monmouth County water is typically a mixed bag through the season — winter flounder, blowfish, tautog, bluefish, summer flounder, and striped bass are all normally part of the local catch rotation, which lines up with the variety showing up in this week's reports.

Whether this year's turnover is running early, on-schedule, or late isn't something the available intel can confirm — none of the sources in this feed offer a direct year-over-year comparison for Raritan Bay or Sandy Hook specifically. Multiple captains characterizing the last two weeks of August as "finally" improving after a slower stretch suggests this season may have been a bit behind typical pace, but that's an inference from tone rather than a stated fact, so it should be treated as a soft read rather than a confirmed trend.
