Fishing score 74/100

How this score is calculated

Water temperature16.6 / 18

66°F against a 58–85°F band for redfish.

Tide movement7.0 / 20

Slack low at 0.5 ft, moving 0.1 ft/hr. Near slack — expect fish to reposition and the bite to pause.

Wind6.6 / 11

16 mph out of the N. Workable wind with useful chop.

Swell & surf10.0 / 10

2.3 ft at 14 seconds. Good working surf for beaches and inlets.

Water clarity9.0 / 9

Good working clarity with some colour for cover.

Barometric pressure7.4 / 9

29.86 inHg and steady.

Moon & solunar4.1 / 8

56% illumination — neap tides with a smaller exchange.

Seasonal pattern13.1 / 15

Fall pattern is fully established for this zone.

WhySlack low at 0.5 ft moving 0.1 ft/hr, water at 66°F, 16 mph N wind and 2.3 ft of swell. Top two hours of a flood tide over 5.8 ft is when this zone fishes best, and today's next tide change lines up with that window.

Backup pattern

Speckled Trout — popping cork with a soft plastic in 3–15 ft. Hold on creek mouth drops and deeper oyster edges, especially on the last of the falling tide.

  • Redfish: Tail on the flooded grass on spring tides above about 5.8 ft, then stack in creek mouths on the fall.
  • Speckled Trout: Hold on creek mouth drops and deeper oyster edges, especially on the last of the falling tide.
  • Flounder: Ambush points at the downstream side of oyster bars and dock pilings.
  • Tarpon: Roll through the harbor and along the beaches from July into September, keyed on menhaden pods.

Structure

Habitat and structure that holds fish

  • Spartina marsh
  • Oyster bar
  • Creek mouth
  • Harbor jetty
  • Deep hole
  • Charleston jetties
  • Wando River oyster bars
  • Shem Creek mouth
  • Morris Island cut
  • Folly River flats

Surf and beach notes

Folly and Sullivan's beaches fish best on a small 1–2 ft swell; the fishing here is far more about tide than surf.

Bait in the zone

Live shrimp is the universal bait; fiddler crabs for flood-tide reds and mud minnows for flounder.

Patterns

Season-by-season patterns

Spring

62–74°F

Redfish break into smaller groups and spread across the flats; trout move back up the creeks as water passes 62°F.

Summer

80–86°F

Early morning and flood-tide windows only; mid-day heat pushes fish to deep shade and moving water.

Fall

68–80°F

The best season — shrimp flush out of the marsh, trout fire up and redfish school in big schools on the flats.

Winter

50–58°F

Redfish form tight schools of 50-plus fish in shallow mud basins and are visible on calm sunny afternoons.

The water

About Charleston Harbor & Lowcountry

Charleston's 5.5 ft tide range floods thousands of acres of spartina grass twice a day, and redfish follow the water in to root fiddler crabs out of the mud. When the tide is out, the same fish stack on oyster bars and in the creek mouths. Nothing about fishing here works without reading the tide chart first.

Local knowledge

Expert notes

  • Flood-tide redfish need a predicted tide above roughly 5.8 ft in Charleston Harbor. Below that, the grass never floods deep enough for fish to get in.
  • Tailing fish give away their position with a wagging tail and moving grass stems — watch the grass, not the water.
  • In winter, the schooled-up reds in shallow mud basins spook from a pushed wake. Pole or wade the last 100 feet, and cast well past the school.
