What You'll Find in Rehoboth Bay

Rehoboth Bay is a shallow, productive estuary that holds striped bass, bluefish, flounder, and weakfish depending on the season. The bay runs roughly north-south between the Delaware Bay inlet and the Atlantic, with depths ranging from 2 to 12 feet across most of it. Unlike the open ocean off Rehoboth Beach, the bay is calmer, warmer in summer, and easier to fish from smaller boats, kayaks, or the shore.

The bay's character changes dramatically with water temperature and season. Spring brings stripers moving in from deeper water. Summer heats the shallows and pushes fish to deeper channels and the inlet. Fall is the most productive time—baitfish concentrate, predators follow, and the water cools. Winter thins out the action, though some stripers stay in the deeper holes.

Key Takeaways

  • Rehoboth Bay holds striped bass, bluefish, flounder, and weakfish, with the species and size changing by season and water temperature.
  • Spring (April–May) and fall (September–October) are the most reliable times to fish, with summer requiring deeper channels and early morning or evening trips.
  • The inlet at the bay's southern end and the deeper holes along the channel hold fish year-round, but shallow flats produce in spring and fall.
  • Access from shore is possible at several public ramps and beaches, but a small boat or kayak opens up the productive middle and northern sections of the bay.

Spring: Stripers and Shad Moving Through

April and May bring striped bass into Rehoboth Bay as they migrate north from wintering grounds. Water temperatures climb from the mid-50s to the low 60s, and shad begin their spawning run up the Delaware River. Stripers follow the baitfish, and the bay becomes a feeding corridor.

Fish the deeper channel that runs north from the inlet—roughly 8 to 12 feet of water—with live shad, herring, or bunker. Early morning and late afternoon produce better than midday. The area around the inlet mouth itself holds fish all day, especially on the incoming tide. Casting small white bucktails or swimbaits along the channel edges works well from a boat; from shore, the public ramps at Dewey Beach and Indian River Inlet give you access to deeper water without a long wade.

Spring stripers in the bay run 18 to 28 inches on average, with occasional fish in the 30-inch range. The action peaks in mid-May as water temperature reaches the upper 60s and baitfish abundance peaks.

Summer: Deeper Water and Tidal Timing

By June, water temperature climbs into the 70s and stays there through August. Shallow flats warm up and become less attractive to stripers and bluefish. Fish move to the deeper channel, the inlet, and the cooler water near the mouth where the bay meets the Atlantic.

Early morning and evening trips produce far better than midday. Fish the channel with live bait or slow-moving swimbaits, focusing on the hour before sunrise and the two hours after sunset. Bluefish become more active than stripers in summer, and they'll chase topwater plugs and small spoons in the early light. Flounder move onto the shallow flats at night and early morning; fish the edges of the channel with live mullet or squid.

Summer also brings weakfish into the bay. These fish are smaller than stripers (12 to 16 inches typical) but abundant and willing. Fish the flats with small soft plastics or live shrimp at dawn and dusk. The inlet mouth holds fish all day, but the bite is most reliable in the first and last hours of light.

Fall: Peak Abundance and Consistent Action

September through October is the best time to fish Rehoboth Bay. Water temperature drops from the 70s into the 60s, baitfish concentrate, and stripers, bluefish, and weakfish move in to feed heavily before winter. The shallow flats become productive again, and you can fish them throughout the day.

Stripers in fall run larger than spring fish—expect 24 to 32 inches regularly, with 35-inch-plus fish possible. Fish the flats with live shad or herring, or cast small white and chartreuse bucktails. The channel holds fish too, but the flats are more forgiving and more fun. Bluefish are aggressive and abundant; they'll hit topwater plugs, metal spoons, and nearly any moving lure. Weakfish school up in fall and respond well to small soft plastics and live bait.

Tidal timing matters less in fall than in spring or summer—the bite is good throughout the day, though early morning and late afternoon still edge out midday. The action remains strong through mid-October, then begins to thin as water temperature drops below 60 degrees.

Winter: Holding Fish in Deep Holes

November through March is slow but not empty. Water temperature drops into the 40s and 50s. Most fish move to the deepest holes in the bay or out to deeper offshore water. Stripers that stay are lethargic and eat less frequently. Bluefish largely disappear. Flounder move to the inlet and deeper channels.

If you fish winter, focus on the deepest holes—around 10 to 12 feet—and fish slowly with live bait. Early morning is better than afternoon. The bite is sporadic, and you may go hours without action. Many local anglers shift to the inlet or the ocean during winter rather than spend time in the bay.

Access Points and Boat Ramps

The Dewey Beach public ramp (Rehoboth Avenue at the bay) is the most convenient launch for Rehoboth Bay. It has parking, a concrete ramp, and direct access to the bay. Indian River Inlet, just north of Rehoboth Beach, has a state-managed ramp and is busier but also productive—the inlet mouth itself holds fish year-round.

Shore access is limited but possible. The Rehoboth Beach Boardwalk overlooks the bay, and while you won't catch large fish there, small stripers and bluefish are taken by anglers fishing the pilings. Dewey Beach has public beach access, and you can wade the shallows at low tide. The Indian River Inlet bridge allows foot traffic, and anglers fish from the rocks and pilings, though the current is strong and footing is tricky.

Kayak fishing is popular in Rehoboth Bay because the water is shallow and calm. Launch from Dewey Beach or the Indian River Inlet ramp, and you can reach productive flats and channels that are hard to access from shore. Stay aware of boat traffic, especially near the inlet.

Tides, Currents, and Reading the Water

Rehoboth Bay is tidal, and the inlet at the south end drives most of the flow. Incoming tide pushes water into the bay and concentrates baitfish along the channel edges. Outgoing tide pulls water and baitfish toward the inlet, concentrating fish there. The strongest current runs in the inlet itself; the bay proper has gentler flow.

Water clarity varies. After heavy rain, the bay turns murky from freshwater runoff. Clear water is better for sight-fishing and lure casting, but fish feed in stained water too—they just rely more on vibration and smell. Baitfish are the best indicator of where to fish: where you see mullet, shad, or bunker schooling, stripers and bluefish are usually nearby.

The bay's shallow depth means it warms and cools quickly. A warm spell in April can trigger a strong bite; a cold snap in May can shut it down for a few days. Pay attention to the forecast and water temperature trends rather than fishing by calendar alone.

Frequently Asked Questions

What's the difference between fishing Rehoboth Bay and the ocean off Rehoboth Beach?

The bay is shallower, calmer, and warmer in summer, making it easier to fish from small boats and kayaks. The ocean has larger fish and stronger currents but requires more experience and better weather. The bay is better for learning and for consistent action in spring and fall.

Do I need a boat to fish Rehoboth Bay?

No. You can fish from shore at Dewey Beach, the inlet, and the boardwalk. A boat or kayak reaches more productive water and gives you access to the flats and deeper channel, but shore fishing works, especially in fall when fish move into shallower water.

What's the best bait for Rehoboth Bay?

Live shad and herring work year-round for stripers. Live mullet and squid work for flounder. Live bunker (menhaden) works for bluefish and large stripers. If live bait is hard to find, small white bucktails and swimbaits catch fish in spring and fall.

Can I fish Rehoboth Bay in winter?

Yes, but the action is slow. Fish move to the deepest holes and eat less frequently. Most anglers shift to the inlet or ocean in winter. If you fish the bay in winter, focus on deep water and live bait, and expect long stretches without a bite.

What size fish should I expect to catch?

Stripers run 18 to 28 inches in spring, 24 to 32 inches in fall. Bluefish are typically 12 to 20 inches. Flounder run 14 to 20 inches. Weakfish are smaller, usually 12 to 16 inches. Fall produces the largest fish overall.
