The Short Answer: Late Spring Through Fall
Atlantic croaker (named for the grunting, croaking sound they make when you catch them — yes, really) aren't in the Chesapeake year-round. They spend the winter offshore in the warmer, deeper waters of the Atlantic Ocean, then migrate back into the Bay once things warm up. You can generally expect them to start showing up in late April to mid-May, with numbers building through June and peaking in summer.
Why Water Temperature Is Everything
Croaker are cold-blooded, which means the water temperature basically controls their whole calendar. They get uncomfortable in water below about 55°F and really get active once it climbs past 60–65°F. In the Chesapeake, that usually happens in the shallower tributaries — the smaller rivers and creeks that feed into the Bay — before the main Bay itself warms up. This is a useful thing to know: in early spring, target the tributaries first, not the wide-open Bay. The shallower water heats up faster, and the croaker find it first.
Month-by-Month Breakdown
- April: Still pretty early. Water temps are usually 50–58°F. A few early croaker might show up in the warmest, shallowest spots on a warm stretch of days, but don't count on it yet.
- May: This is when things get interesting. Water crosses that 60°F mark, especially in tidal creeks and river mouths (where rivers meet the Bay). Croaker start moving in and biting.
- June–August: Prime time. Croaker are spread throughout the Bay and its tributaries. They're feeding hard and relatively easy to catch — great for beginners.
- September–October: Still solid fishing, but croaker start staging near the Bay mouth (the southern opening toward the ocean) as they prepare to head back offshore.
- November onward: Most croaker have left. A few stragglers hang around into early November in mild years, but don't plan a trip around it.
Where They Hang Out When They Arrive
Croaker love soft, muddy or sandy bottoms — think channel edges (the deeper, sloping sides of underwater channels where boats navigate), dock pilings, and the mouths of tidal creeks. They're bottom feeders, meaning they root around near the floor looking for worms, small crabs, and clams. That's why they're almost always caught with bait fished right on the bottom rather than up in the water column.
A Simple Setup to Get Started
Once you know croaker are in the area, the go-to rig is a bottom rig (also called a fish-finder rig) — basically a weight that sits on the bottom with a short line and hook above it. Size 1 to 1/0 hooks work well; croaker have smaller mouths than they look. Bloodworms, cut squid, and peeler crab (a blue crab that's in the process of shedding its shell, making it extra soft and smelly) are the classic baits. Croaker find food mainly by smell, so fresh, smelly bait outperforms almost anything artificial.
The Bottom Line
If you're planning your first croaker trip in Maryland, aim for late May through August for the most reliable action. Watch the water temps if you can — most fishing apps and weather sites list Bay water temperatures — and once you're seeing consistent readings above 62°F, it's game on. Croaker are forgiving, social fish that bite pretty readily, which makes them one of the best species to cut your teeth on in the Chesapeake.
