Black drum move into Delaware Bay as spring species stack up

What's Biting

What's Next

With winds easing to around 5 m/s and air temperatures near 61°F, the mid-week small craft advisory stretch that kept open-water boats docked should give way to more fishable windows heading into the weekend. Shore and inlet anglers who largely fished through the blow should see conditions continue to improve.

The new moon falling today (May 17) is a meaningful timing note. Spring tides bring larger tidal exchanges through inlet mouths like Indian River Inlet, concentrating bait and pulling stripers into prime feeding positions on the jetties and in the South Pocket. Old Inlet Bait and Tackle reported bucktails and plugs working well at the inlet early in the morning; the heightened new-moon tidal pull should sustain that window over the next several days. Fish the first couple hours of the outgoing tide for the best shots at quality fish.

Black drum, now well-established in their spring stations, should remain active through late May — 58°F water is squarely in their preferred spring range and the bite typically holds until the fish scatter ahead of summer. Clams and sand fleas remain the top baits; per Smith's Bait Shop (The Fisherman — DE/MD/Chesapeake), female blue crabs have also been producing at the drum spots.

Black sea bass season is now open in the region. Per The Fisherman (Northeast), New Jersey opened May 15 with a 12.5-inch minimum and 10-fish bag limit through June 21 — Delaware anglers with access to offshore structure can add sea bass to the target list. Check current DNREC regulations for Delaware-specific size and bag limits before harvesting.

The fluke bite is approaching. At 58°F, bay water temps sit just below the threshold where summer flounder activity typically picks up meaningfully. Once the bay creeps into the low-60s — possible within the next one to two weeks — expect flatfish to become a consistent option, particularly near inlet mouths on outgoing tides.

Hickory shad at Indian River Inlet should remain available through late May on shad darts, though this run is typically winding down by Memorial Day.

Context

Mid-May in Delaware Bay typically sits at the heart of the spring multi-species push, and this year appears to be running on schedule. Black drum historically arrive at the Coral Beds off Slaughter Beach in mid-May, migrating north from Chesapeake Bay and Florida wintering grounds; the current arrival reported by Smith's Bait Shop (The Fisherman — DE/MD/Chesapeake) is right on cue for the date.

The broader regional striper picture is strong this season. On The Water's Striper Migration Map (May 15, 2026) notes that migratory fish have pushed as far north as Maine — a sign of a robust coast-wide run that is giving Delaware Bay anglers consistent access to quality fish. The Fisherman — NJ/DE Surf described the same week as "another phenomenal week of surf fishing" for stripers, with fish ranging from slot to well overslot size along the Jersey shore just north of Delaware. That migration corridor runs directly through Delaware Bay, and the consistent action being logged at Indian River Inlet fits squarely within that pattern.

The 58°F buoy reading is typical for mid-May in this region, perhaps a degree or two behind a fast-warm-up year. Saltwater Edge Blog (RI) noted that prolonged wind events held back water temperatures across the Northeast this spring. The slower warm-up has likely pushed the reliable fluke bite back by roughly a week compared to an early-season year, but the overall fishery is healthy and tracking normally.

One regulatory note worth keeping in mind: the Delaware Surf Fishing blog reported that DNREC revised the recreational striped bass summer slot season, establishing a 20–24 inch slot size limit for the July 1 season start. That change is still weeks away, but anglers planning into summer should factor it into their targeting strategy. As always, verify current DNREC rules before retaining any fish.
