What You'll Find on the May River

The May River is a tidal estuary in Beaufort County that flows through salt marsh and maritime forest before emptying into Calibogue Sound near Daufuskie Island. It's a shallow, meandering system where freshwater from inland swamps mixes with saltwater from the Atlantic, creating habitat for redfish, spotted seatrout, flounder, and tarpon. The river runs roughly 20 miles from its headwaters near Bluffton south to the sound, and most fishing happens in the lower half where tidal influence is strongest.

The May River is known for sight-fishing in clear, shallow water — you can often see redfish tailing in the marsh grass or cruising the flats. The river also holds good numbers of spotted seatrout in deeper holes and channel edges, especially during fall and winter. Flounder are present year-round but concentrate in the main channel during colder months. Tarpon show up in summer and early fall, typically in the deeper holes and near the mouth.

Key Takeaways

  • The May River is a shallow tidal estuary best fished by boat, with redfish and spotted seatrout as the primary species.
  • Tides control fishing success here — incoming tides push fish onto the flats and into the marsh, while outgoing tides concentrate them in channels and deeper holes.
  • Access is limited to boat launch at Calibogue Cove near Daufuskie Island or private marinas in Bluffton; there is no public bank fishing.
  • A South Carolina saltwater fishing license is required for anyone 16 and older, and redfish have a slot limit of 18 to 27 inches.
  • Summer water temperatures exceed 85 degrees and fishing slows; fall and winter (October through March) are the most productive seasons.

Seasons and Water Conditions

Fall and winter (October through March) are the best times to fish the May River. Water temperatures drop into the 50s and 60s, and fish become more active and predictable. Redfish school in the deeper channels and holes, spotted seatrout move into the main river from the sound, and flounder concentrate in the deepest sections. October and November are particularly strong because water is still warm enough for sight-fishing on the flats, but fish are feeding aggressively before winter.

Spring (April through May) can be productive but inconsistent. Redfish move back onto the flats as water warms, and spotted seatrout are still present, but the transition period means fish are scattered. Summer (June through September) is slow. Water temperatures exceed 85 degrees, fish move to deeper holes and the sound to find cooler water, and sight-fishing becomes difficult because of algae blooms and reduced visibility. Tarpon arrive in July and August and can be caught in the deeper holes near the mouth, but they require specialized tackle and patience.

How Tides Shape the Fishing

The May River is a tidal system, and tides control where fish are and how they feed. Incoming tides push water into the marsh, flooding the shallow flats and grass edges where redfish hunt for shrimp and small baitfish. Outgoing tides drain the flats and concentrate fish in the main channel, deeper holes, and the mouth of the river. Most anglers fish the incoming tide on the flats for redfish and the outgoing tide in the channels for spotted seatrout and flounder.

Slack tide — the brief period when water stops moving between incoming and outgoing — can be slow because fish stop feeding. Plan your trip around the tide tables, which change daily. The difference between high and low tide on the May River is typically 6 to 8 feet, which is significant in a shallow system. A tide table for Beaufort or Daufuskie Island will tell you when the May River tides occur; the river follows the same pattern as the sound.

Species and What to Target

Redfish are the signature fish of the May River. They range from 15 to 40 pounds and are caught year-round, but fall and winter are most reliable. Sight-fishing for tailing redfish in the marsh grass is the classic method — you pole or drift quietly and cast to fish you can see. Redfish also respond to live shrimp, mullet, or crab fished in the channels and around oyster bars. South Carolina has a slot limit: redfish must be between 18 and 27 inches. Fish outside that range must be released.

Spotted seatrout (called "specks" locally) are abundant in the May River, especially in fall and winter. They school in the deeper holes and channel edges and respond well to live shrimp or small mullet. Spotted seatrout are also caught on artificial lures — small spoons and soft plastics work well. They have a 12-inch minimum size limit and a 10-fish daily bag limit.

Flounder are present year-round and concentrate in the main channel and deeper holes, especially from November through March. Live shrimp or mullet fished on the bottom near structure — oyster bars, drop-offs, pilings — is the standard approach. Flounder have a 12-inch minimum size limit.

Tarpon arrive in summer and early fall, typically in July through September. They are large (50 to 150 pounds) and require heavy tackle, wire leaders, and live mullet or large shrimp. Tarpon fishing on the May River is specialized and best done with a guide who knows where they hold.

Access and Launch Points

The May River is accessible only by boat. The primary public launch is at Calibogue Cove, located on Daufuskie Island near the mouth of the river. To reach it, you must take the Daufuskie Island ferry from Hilton Head Island (operated by Calibogue Cruises) or launch from a private marina in Bluffton and run south. Calibogue Cove has a small ramp, parking, and a dock. Arrive early during peak season because parking fills quickly.

Several private marinas in Bluffton offer launch facilities and sometimes rent boats. These include marinas along the May River itself and on the Calibogue Sound. Call ahead to confirm launch fees, hours, and whether rentals are available. If you don't have a boat, hiring a guide is a practical option — guides know the tides, the fish, and the shallow water intimately and can often put you on redfish or seatrout more reliably than you could alone.

Regulations and Licensing

Anyone 16 years old or older must have a South Carolina saltwater fishing license to fish the May River. You can purchase a license online through the South Carolina Department of Natural Resources website, at most tackle shops, or at sporting goods stores. A three-day license is available if you're visiting; a full-year license is also an option. Licenses are inexpensive and the money funds habitat management and access improvements.

Redfish have a slot limit of 18 to 27 inches — only fish within that size range can be kept, and you may keep one per day. Spotted seatrout have a 12-inch minimum and a 10-fish daily bag limit. Flounder have a 12-inch minimum and a 10-fish daily bag limit. Tarpon are catch-and-release only in South Carolina. Check the current regulations before you fish because rules can change; the South Carolina Department of Natural Resources website has the most current information.

Tackle and Techniques

For redfish, use a 7- to 8-foot medium-power spinning rod with 15- to 20-pound braided line. Live shrimp under a popping cork is effective, as is sight-casting with soft plastics or small topwater plugs. For sight-fishing, polarized sunglasses are essential — they cut glare and let you see fish in the water. A shallow-draft boat (18 to 22 feet) or a poling skiff is ideal because the May River averages 3 to 6 feet deep and has shallow flats.

For spotted seatrout, use similar tackle — a 6.5- to 7-foot medium spinning rod with 12- to 15-pound line. Live shrimp or small mullet work well, as do soft plastics and small spoons. Fish the deeper holes and channel edges, especially on the incoming tide. For flounder, use a slightly heavier setup (15- to 20-pound line) and fish live shrimp or mullet on the bottom near structure. For tarpon, you'll need heavy tackle (8- to 9-foot rod, 30- to 50-pound line, wire leader) and should fish with a guide.

Frequently Asked Questions

Do I need a guide to fish the May River?

A guide is not required, but the May River is shallow, tidal, and easy to run aground if you don't know the channels. If you have boat experience and access to a tide table, you can fish it on your own. If you're new to the area or don't have a boat, a guide is a practical choice and often results in more fish.

What's the best time of day to fish?

The tide matters more than the time of day on the May River. Fish the incoming tide on the flats in the morning or afternoon, and the outgoing tide in the channels. If the tide is right, you can catch fish at any hour. Check the tide table and plan your trip around it rather than around sunrise or sunset.

Can I fish from shore on the May River?

There is no public shore access on the May River. The banks are private property or protected marsh. You must fish from a boat. If you don't have one, you can rent from a marina in Bluffton or hire a guide.

What should I bring for a day on the May River?

Bring plenty of water, sunscreen, polarized sunglasses, a tide table or tide app, your fishing license, and a cooler with ice. The sun reflects off the water and marsh, and dehydration happens fast. Wear light-colored, long-sleeved clothing to reduce sun exposure. Bring a first aid kit and a headlamp if you plan to fish into dusk.

Are there restrictions on where I can fish?

Some areas of the May River are closed to fishing or have special rules — check with the South Carolina Department of Natural Resources or a local tackle shop before you go. Daufuskie Island has private property, and some marshes are protected. Stick to the main river and sound unless you know an area is open.
