What the Wilmington River Offers

The Wilmington River is a tidal estuary that flows into the Atlantic near Savannah, Georgia, and holds a mix of saltwater species that shift with the seasons. You'll find redfish, spotted seatrout, flounder, and tarpon depending on the month and tide. The river runs roughly 20 miles from its headwaters south of Savannah down to Tybee Island, with access points scattered along its length—some public, some requiring permission or a boat launch fee.

The river's character changes as you move downstream. Upper sections near Savannah hold more brackish water and attract redfish and trout year-round. The middle and lower river, closer to Tybee, are fully saltwater and draw larger species, especially tarpon in summer. Mud flats, marsh grass, and deeper channels all hold fish, but each requires different tactics and timing.

Tides control everything here. The Wilmington River has a tidal range of 6 to 8 feet, and fish move with the water. High tide pushes them into shallow marsh edges; low tide concentrates them in deeper channels. Checking tide tables before you go is not optional—it determines where fish will be and whether you can even reach certain areas.

Key Takeaways

  • Redfish and spotted seatrout are the most reliable targets year-round, with tarpon arriving in summer and fall.
  • Public boat launches exist at Savannah, Thunderbolt, and Tybee Island, though some charge a daily fee and parking can fill quickly on weekends.
  • Tides control fish location and water access—plan your trip around tide tables, not just daylight hours.
  • Georgia saltwater fishing requires a saltwater license unless you fish from a licensed charter or public pier, and bag limits vary by species.
  • Wading is possible in many areas, but mud flats and marsh grass require shallow-draft boats or kayaks for the best access.

Seasons and What Fish Are Present

Spring (March through May) brings warming water and active redfish and trout in the shallows. Spotted seatrout spawn in April and May, and they concentrate in deeper holes and channels during this period. Water temperatures climb from the 50s to the low 70s, and fish feed heavily. Mullet runs begin in late spring, which draws larger predators.

Summer (June through August) is tarpon season. These large, hard-fighting fish move into the Wilmington River from June onward, especially in the lower river and around Tybee. Redfish remain active but move deeper during the hottest parts of the day. Early morning and late evening are most productive. Trout bite slows in peak heat but returns in late August as water temperatures begin to moderate.

Fall (September through November) is arguably the best overall season. Water cools, fish become aggressive, and both redfish and trout feed heavily. Tarpon remain present through October. Mullet runs peak in September and October, drawing everything that eats fish. Conditions are comfortable, and the river is less crowded than summer.

Winter (December through February) slows the bite but does not stop it. Redfish and trout move to deeper channels and holes. Cold snaps can shut down fishing for a few days, but mild spells bring brief windows of activity. Winter is the quietest season on the water, which appeals to anglers who prefer solitude.

Public Access and Boat Launches

The main public boat launch on the Wilmington River is at Savannah Riverfront Park in downtown Savannah. It has multiple ramps, parking, and restrooms, but it fills quickly on weekends and holidays. There is no launch fee, but parking can be tight. This launch puts you in the upper river, which is good for redfish and trout but requires running downstream to reach tarpon water.

Thunderbolt Marina sits on the river south of Savannah and offers a public launch for a daily fee (typically $5 to $10, though this varies). Parking is more available than at Savannah Riverfront, and you're closer to the middle and lower river. Several private marinas in Thunderbolt also offer launch access if you're willing to pay.

Tybee Island has public access at the north end, near the pier and lighthouse. The Tybee Island Boat Ramp is free and puts you in the lower river and near the inlet, which is prime tarpon and larger trout water. Parking fills on summer weekends, and the ramp can be crowded. Arrive early or fish on weekdays if you want a smoother launch.

Wading is possible in many areas, particularly the upper and middle river where mud flats and marsh edges are accessible. You do not need a boat to fish these areas, though a kayak or shallow-draft skiff gives you more range. Wear wading boots—the bottom is soft mud and oyster shells, and the mud can be slippery.

Regulations and Licensing

Georgia requires a saltwater fishing license for anyone 16 and older who fishes in saltwater, with limited exceptions. You do not need a license if you fish from a licensed charter boat or from a public pier (like the Tybee Pier). Licenses are available online through the Georgia Department of Natural Resources website, at tackle shops, and at some sporting goods stores. A three-day license costs less than an annual one if you're visiting briefly.

Bag limits and size restrictions vary by species. Redfish have a 27-inch minimum and a daily bag limit of 3 fish per person. Spotted seatrout have an 18-inch minimum and a 10-fish daily limit. Tarpon is catch-and-release only—you cannot keep them. Flounder have a 14-inch minimum and a 10-fish daily limit. Check the current Georgia saltwater regulations before you fish, as rules can change year to year.

Closed seasons apply to some species. Spotted seatrout have a spawning closure in April and May in some areas, though this varies by zone. Redfish have no closed season in the Wilmington River area. Always verify current rules with the Georgia DNR or a local tackle shop, as regulations shift and local knowledge is worth the phone call.

Tactics for Redfish and Spotted Seatrout

Redfish respond to live bait and artificial lures. Live mullet, shrimp, and pinfish work well, especially on incoming tides when fish move into shallow marsh edges. Cast near the grass line and let the bait sit or move slowly. Redfish are not shy about hitting a meal, so patience and the right location matter more than finesse. Artificial lures—spoons, soft plastics, and topwater plugs—also draw strikes, particularly in clear water and on sunny days.

Spotted seatrout are more finicky. They prefer live shrimp under a popping cork, which creates noise and movement that triggers strikes. Cast near deeper holes and channel edges, especially during slack tide or early in the tide change. Trout have softer mouths than redfish, so lighter tackle and a steady hand on the hook set reduce break-offs. Artificial lures work too, but live bait is more consistent in the Wilmington River.

Tide timing is critical for both species. Fish move into shallow water on rising tide and retreat to deeper channels as the tide falls. Plan to fish the shallows during the last two hours of incoming tide and the first hour of high tide. As the tide drops, move to deeper water and channel edges where fish concentrate. Slack tide—the brief period between tide changes—can be slow, so use it to move to a new spot.

Tarpon in Summer and Fall

Tarpon arrive in the Wilmington River in June and remain through October, with peak numbers in July and August. They are large, powerful fish that require heavy tackle and patience. Most tarpon fishing in the river is sight-casting—you spot the fish cruising in shallow water and cast ahead of it. Mullet and mackerel are the preferred baits, though large artificial lures also work.

The lower river and areas near Tybee Island hold the most tarpon. Fish the incoming tide in the early morning when the water is calm and visibility is best. Tarpon are spooky and will flee if they see the boat, so approach slowly and quietly. When you hook one, expect a long fight—tarpon are acrobatic and can jump repeatedly, and they often break free. Bring heavy rod, strong line, and a lot of patience.

Tarpon is catch-and-release only in Georgia, so the goal is the fight and the memory, not the meal. Many anglers hire a guide for tarpon fishing because spotting and approaching these fish requires skill and experience. If you're new to tarpon, a half-day guide trip is worth the cost to learn the technique.

When to Fish and Weather Patterns

Early morning and late afternoon are most productive year-round. Fish feed actively during low-light hours, and the water is often calmer. Midday can be slow, especially in summer when heat drives fish deeper. Overcast days often produce better bites than bright, sunny days, though tarpon fishing benefits from clear water and good visibility.

Wind affects fishing more than most anglers expect. Strong wind makes sight-casting difficult and pushes water around, which can disrupt feeding patterns. A light breeze is fine; sustained winds above 15 knots make the river choppy and fishing harder. Check the forecast before you commit to a trip, and be prepared to fish different areas if the wind picks up.

Rain does not stop fishing and often improves it. Fish feed more actively when barometric pressure drops before a storm. However, heavy rain can reduce visibility and make navigation tricky, especially in shallow areas. Afternoon thunderstorms are common in summer—start early and be off the water by mid-afternoon if storms are forecast.

Frequently Asked Questions

Do I need a guide to fish the Wilmington River?

No, but a guide is valuable if you're new to the river or targeting tarpon. Guides know where fish concentrate by season, how to read tides, and how to approach fish without spooking them. For redfish and trout, local knowledge helps, but you can learn the river yourself by fishing it multiple times and keeping notes on what works.

Can I fish from shore or do I need a boat?

You can fish from shore in some areas, particularly around Tybee Island and at the Savannah Riverfront. However, a boat or kayak gives you access to more water and better positioning for tides. Wading is possible in the upper and middle river, but you'll be limited to shallow areas. A kayak is a good middle ground—affordable, quiet, and effective for redfish and trout.

What's the best time of year to visit?

Fall (September through November) offers the most consistent fishing, comfortable weather, and fewer crowds. Spring is also good, with active redfish and trout. Summer is best if you want to target tarpon, but heat and afternoon storms can make it challenging. Winter is quiet and can be productive, but cold snaps shut down fishing temporarily.

Are there tackle shops near the river where I can get local advice?

Yes. Savannah and Thunderbolt have several tackle shops that cater to Wilmington River anglers. Staff can tell you what's biting, where fish are concentrated, and what regulations are current. They also sell live bait and can point you to the best launch for your target species. A quick phone call before you fish saves time and improves your chances.

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

Bring plenty of water, sunscreen, and a hat—the sun reflects off the water and burns quickly. Wading boots or shoes with good grip are essential if you plan to wade. A tide table or tide app on your phone is mandatory. Bring more bait than you think you'll need, a net, and a cooler if you plan to keep fish. A first aid kit and a headlamp are good backups, especially if you fish early or late.
