April is when Charleston's inshore system wakes up — redfish, trout, and sheepshead are all fishing well at the same time. Here's how to decide which to target based on conditions, bait, and what's actually producing right now.
April is the month Charleston's inshore system wakes up. Water temps are pushing through the low-to-mid 60s, bait is flooding back into the creeks, and three of the most popular inshore species are all fishing well at the same time. The question isn't whether to go — it's what to target.
Here's how redfish, speckled trout, and sheepshead stack up in April, what's actually driving the bite for each one, and how to decide which to chase on any given day.
Redfish: The Safe Bet
April redfish in Charleston are in full spring transition mode. The tight winter schools that stacked up on deep dock lines and channel edges through January and February have broken apart. Fish are spreading out across flats, creek mouths, and marsh edges — and they're hungry.
Water temperature is the trigger. Once creek water pushes past 62°F consistently, redfish shift from sluggish bottom-hugging behavior to active, aggressive feeding. By the time water hits 68–72°F — which most of the Charleston system sees by mid-to-late April — the spring pattern is fully locked in.
The tide stage matters more now than it did in winter. On incoming water, reds push up onto flooded grass edges and oyster flats to feed. On outgoing, they stack at creek mouths and drain points where bait gets funneled off the marsh. The first and last hours of tide movement are almost always more productive than slack water.
Bait selection in April is straightforward. Brown shrimp are the dominant live bait right now — they fill the gap between March and the white shrimp arrival in June. A live brown shrimp under a popping cork on incoming tide over a grass flat is about as close to a guaranteed eat as April fishing gets. On outgoing, a cut mullet or mud minnow on a Carolina rig near a drain point is hard to beat.
Fiddler crabs are just starting to become active as ground temperatures climb above 65°F. They're not the dominant bait yet — that comes in May and June — but they're worth having in the bucket if you're fishing oyster edges or marsh banks on a low tide.
If you want the highest probability of putting a fish in the boat, redfish are your April answer. They're the most abundant, most spread out, and most forgiving of the three species right now.
April Redfish Gear

Speckled Trout: The Momentum Pick
Trout fishing in April is improving fast, and the DNR captain reports confirm it. After a slow winter in the creeks, warming water is pushing trout into more predictable feeding patterns on moving water.
The key difference between targeting trout and targeting reds in April is structure preference. Reds will eat on an open flat. Trout want an edge — a grass line next to a drop, a creek mouth with current pushing through, a channel shoulder where the flat breaks into deeper water. They're ambush feeders that stage where current delivers food to them.
Live shrimp under a popping cork remains the single most effective trout rig in Charleston, and it's not particularly close. The sound of the cork draws fish from distance, and a live shrimp dangling 18 inches below it is almost impossible for a feeding trout to resist.
For artificial anglers, April is when topwater starts working again during low-light periods — first hour of daylight and last hour before dark. A soft twitch bait on a slow retrieve along a grass edge at dawn can produce some of the biggest trout of the spring. As the sun gets higher, switch to a jig head with a paddle tail and work channel drop-offs with a count-down-and-retrieve.
Trout are the momentum pick for April because the bite is trending upward every week as water warms. The fish you catch in early April will be creek residents that overwintered. By late April, the larger migratory fish start showing up in the main rivers. If you're willing to work edges and moving water, trout can outproduce reds on the right days.
April Trout Gear
- Popping cork rig: Cajun Thunder popping cork, 18" of 20-pound Seaguar Blue Label fluorocarbon, 1/0 Owner Mutu Light circle hook, live shrimp
- Topwater: Heddon Super Spook Jr in bone or silver — work it slow with a walk-the-dog retrieve during low light
- Twitch bait: MirrOlure MirrOdine in natural colors — cast along grass edges, twitch-twitch-pause
- Jig: 1/4-ounce Z-Man Trout Eye jighead with a Z-Man DieZel MinnowZ in opening night or chartreuse
Sheepshead: The Technical Challenge
April sheepshead fishing in Charleston is legitimately good — and most anglers completely overlook it. The larger fish that moved offshore to spawn in late winter are returning to inshore structure right now. Combined with the smaller resident fish that never left, there are solid numbers of sheepshead around docks, bridge pilings, jetties, and oyster bars throughout the harbor system.
The DNR captain report for April rates sheepshead as "good" with a strong bite expected around inshore structure. Fiddler crabs are the number one bait — collect them from soft-bottom marsh edges at low tide and fish them on a small circle hook with minimal weight, tight to pilings.
The challenge with sheepshead is the bite itself. These fish don't hit like a redfish. They compress the bait against structure with their flat, crushing teeth, and what you feel in your rod is a subtle pressure or weight — not a strike. If you wait for a hard pull, you'll miss them every time. The technique is to keep your bait within inches of structure, feel for any change in weight or tension, and set the hook on anything that feels different.
Fresh oyster pieces and shrimp chunks also work, especially if you crush a few live oysters against the piling as chum first. The key is vertical presentation — you want your bait falling right alongside structure, not drifting away from it in the current.
Sheepshead regulations in South Carolina are 14-inch minimum and 10 fish per day with no closed season. They're excellent table fare — firm, white, mild flesh that's often compared to crab meat. Verify current regulations at scdnr.sc.gov before heading out.
If you're a patient angler who likes technical fishing and wants to bring home dinner, sheepshead are the play. If you need action and bites to stay interested, pick one of the other two.
April Sheepshead Gear
- Primary rig: 1/0 Gamakatsu Octopus circle hook, one or two split shot for weight, fiddler crab hooked through the back of the shell
- Backup bait: Fresh shrimp pieces or oyster chunks on the same hook — crush live oysters against the piling as chum
- Leader: 15-pound Seaguar Blue Label fluorocarbon — sheepshead are line-shy around clear water pilings
- Rod tip: A sensitive rod tip matters more than power for sheepshead. You need to feel the compression bite, not overpower the fish.
So Which One?
Here's the decision framework.
If the wind is light and the tide is moving through a flat or creek system — fish redfish. They're the most accessible and forgiving species in April. You don't need perfect conditions or perfect technique. Get in the right area at the right tide stage and they'll eat.
If you want to challenge yourself with finesse and timing — fish trout on moving water with artificials, or target the dawn topwater window. The bite is trending upward every week and the fish are getting more aggressive as water warms.
If you want to bring home the best meal of the three — find a dock line or bridge with oyster growth, bring fiddler crabs, and fish sheepshead. It's slower, it's harder, and the bite is subtle. But a limit of sheepshead is arguably the best eating fish in the Charleston inshore system.
Or do what the smartest anglers do: check the conditions first. Tide stage, water temperature, wind direction, and bait availability change the equation every day. What's best on a calm incoming tide Tuesday morning is different from what's best on a windy outgoing tide Saturday afternoon. The species that matches the conditions is always the right answer.
