Sea bass limits and stripers still churning as Sandy Hook enters summer mode

What's biting

What's next

The first quarter moon on June 21 brings moderate tidal movement — manageable current through the Sandy Hook rips and outer Raritan Bay channels rather than the ripping exchanges of a full or new moon. That rhythm typically creates reliable feeding windows at the turn of each tide, particularly at dawn and dusk, when stripers push up into the rips to ambush bait swept by the current. Plan your sessions around those transitions rather than committing to midday hours.

Water temperatures near Atlantic Highlands are running at 61°F per Capt Ron's most recent report — a welcome rebound from mid-50s readings that were slowing the fluke bite just a couple of weeks ago. As temperatures continue ticking toward the mid-60s over the coming week, expect summer flounder to spread more aggressively from the back bays to the ocean-facing beaches. Capt Ron's has been targeting keepers on rocky ocean bottom with heavier rigs, noting that Gulp has been the standout bait and that six-to-ten-ounce sinkers are necessary to stay connected in the current. That approach should remain productive through the weekend.

Striped bass are the main event right now, and the bite should hold through at least the early part of next week. On The Water's June 19 migration map puts bigger fish on sand eels, squid, bunker, and herring — all available off Sandy Hook and in the outer bay. Grumpys Tackle names clam as the consistent surf producer, while OTW Northern New Jersey's June 18 report confirms that stripers are also hitting plugs and bunker chunks. Dawn and dusk on a moving tide are the money windows; midday fishing will be tougher as surface water warms through the afternoon.

Sea bass limits remain within reach on nearby reef structure. Blue Chip Sportfishing has been limiting out on nearly every trip, and that production should continue as long as water temperatures on the reefs stay below the mid-60s. Bluefin tuna activity is picking up to the south per OTW Northern New Jersey's June 18 report, and Blue Chip describes mako sharks as "busted wide open" offshore — anglers pushing past the 20-mile mark this weekend may find big-game bonus targets on top of their bottom-fishing plans.

Context

Late June in Raritan Bay and off Sandy Hook historically marks the hinge between spring migration and summer resident fishing. The classic pattern sees striped bass that pushed through Delaware Bay and up the coastline from April through May begin to thin and concentrate on offshore structure and canyon edges by early July, leaving behind a resident population of schoolie-to-slot fish in the bay and along the Hook's beaches through summer.

What sources are reporting this week is consistent with that transition being in progress rather than complete. Blue Chip Sportfishing and Grumpys Tackle both describe active striper fishing, and On The Water's June 19 migration map confirms the run has not yet fully dispersed northward — bigger fish are still keyed on local bait concentrations. This suggests the window for quality spring-run bass is narrowing but still open, making the next ten days an important period for anglers who want to intercept migrating fish before they slide offshore.

Fluke season in Raritan Bay typically comes fully online during the third week of June, when water temperatures settle into the low-to-mid 60s. Capt Ron's reports of improving keeper counts on rocky ocean bottom at 61°F fit the expected seasonal arc. A cold snap in early June pushed readings into the mid-50s and briefly slowed the bite, but conditions are now tracking normally for this date — on schedule rather than notably early or late.

Sea bass on the reefs is a reliable mid-summer staple in this corridor, and Blue Chip's near-daily limits suggest the fishery is at or slightly ahead of a typical year. The mako shark activity and bluefin tuna bite noted to the south by OTW Northern New Jersey both align with late-June arrivals of warmer pelagic water off the mid-Atlantic shelf. NOAA Fisheries adjusted 2026 bluefin retention limits effective June 1, so offshore anglers should confirm current possession rules before keeping any tuna, per NJ Saltwater Fisherman. Overall, the Raritan Bay and Sandy Hook corridor is right on the seasonal calendar, with the spring-to-summer transition well underway and multiple fisheries firing simultaneously.
