What the Port Arthur jetties offer and how to fish them

The Port Arthur jetties—the north and south rock structures that frame the ship channel entrance—hold redfish, spotted seatrout, and Spanish mackerel within casting distance of the rocks themselves. The jetties are public and free to access, but they require different tactics than bay fishing because the current runs hard, the rocks are sharp, and the fish hold tight to structure. You can wade or fish from the rocks depending on tide and your comfort level, but most anglers bring a small boat to reach the outer sections where the larger fish congregate.

The jetties work best during incoming tide, when baitfish get pushed toward the rocks and predators position themselves to feed. The south jetty is more accessible to waders and produces consistent catches of redfish and trout in the 15- to 20-inch range. The north jetty is rockier, deeper, and better suited to boat anglers targeting Spanish mackerel and larger reds. Both structures hold fish year-round, though spring and fall bring the most reliable action.

Key Takeaways

  • The south jetty is wadeable at low tide and holds redfish and spotted seatrout within the first 100 yards of rocks.
  • Incoming tide concentrates baitfish and feeding fish at the jetty face, making it the best window for casting.
  • Bring a small boat or kayak to reach the outer rocks where Spanish mackerel and larger redfish hold, especially in summer and fall.
  • The rocks are sharp and the current runs fast; wear cut-resistant gloves and watch your footing on wet surfaces.
  • Live mullet, live shrimp, and topwater plugs all produce, but soft plastics on light jig heads work best in the current.

Wading the south jetty at low tide

The south jetty is the more forgiving of the two for waders. At low tide, you can walk out 80 to 120 yards on the rocks without needing a boat, and the water depth stays between 3 and 6 feet along the face. Wear felt-soled wading boots or shoes with good grip—the rocks are slick even when they look dry, and a fall into the channel current is dangerous. Bring a wading belt and keep your weight low; the rocks are uneven and the current will push at your legs.

Fish the first 50 yards of rocks hardest. Redfish and trout hold in the pockets and along the base where the rocks meet the sand. Cast parallel to the jetty rather than perpendicular to it; the fish are not in the deep water beyond the rocks, they are in the shallower zone where structure meets the bay floor. A 1/8-ounce jig head with a 3-inch soft plastic in pearl or chartreuse works in the current without snagging constantly. If you are using live bait, a small popping cork 18 inches above a live shrimp keeps the bait in the strike zone and lets you work it with movement.

Low tide is also when the rocks are most exposed and the current is slowest, making it safer to wade. High tide covers the rocks, deepens the water, and pushes the current harder—wading becomes risky and less productive because the fish spread out into deeper water. Plan your wade for the two hours before and after low tide.

Boat fishing the outer rocks and north jetty

A small boat or kayak opens up the outer rocks and the north jetty, where the larger fish hold. The outer section of the south jetty and the entire north jetty sit in 8 to 15 feet of water, and the current runs stronger there. Spanish mackerel patrol the outside edge, especially in summer and early fall. Redfish and trout hold in the deeper pockets along the north jetty face.

Anchor uptide of the rocks and cast downcurrent, letting your lure or bait drift past the structure. The fish are feeding into the current, so they face away from you; cast beyond the rocks and retrieve back toward them. Live mullet or live shrimp work well, but a 2-inch soft plastic on a 1/4-ounce jig head is easier to cast in the wind and current. Topwater plugs produce strikes in low-light conditions—early morning and late afternoon—especially on the north jetty where the water is deeper and the baitfish are more concentrated.

The north jetty is steeper and rockier than the south jetty. Do not attempt to wade it; the rocks are unstable, the water is deeper, and the current is faster. Boat anglers should keep a safe distance and watch for other vessels. The channel is active with commercial and recreational traffic, so stay alert and do not anchor in the main shipping lane.

Seasonal patterns and best times to fish

Spring (March through May) brings warming water and active redfish and trout. The jetties produce steady action on soft plastics and live shrimp. Incoming tide during the warming part of the day—late morning through early afternoon—is most productive. Spanish mackerel begin showing in late April and May, especially on the outer rocks.

Summer (June through August) is hot, but the jetties remain productive. Spanish mackerel are abundant and aggressive on topwater and small jigs. Redfish move deeper and hold tighter to the rocks; fish the early morning and late evening hours when the water is cooler and the light is low. Incoming tide is still the best window, but the bite can be slower during midday heat.

Fall (September through November) brings the most consistent action. Water temperature drops, baitfish concentrate, and redfish and trout feed aggressively. Spanish mackerel remain active through October. This is the best season for both waders and boat anglers. Incoming tide during the morning hours produces the most reliable catches.

Winter (December through February) slows the bite but does not stop it. Redfish and trout move to deeper water in the bay, but the jetties still hold fish, especially on warmer days when the sun warms the rocks. Incoming tide is still important, but the bite window is shorter. Expect fewer fish but larger average size.

Tackle and bait that work at the jetties

Light to medium spinning tackle is standard. A 6.5- to 7-foot rod with a 2500 to 3000 series reel and 15- to 20-pound braided line handles the current and the sharp rocks. Braided line cuts easier on the rocks than monofilament, but it is more visible to the fish; use a 2-foot fluorocarbon leader to reduce visibility. Bring extra line and leaders—you will lose tackle to the rocks.

Soft plastics on jig heads are the most versatile option. A 1/8-ounce head works in shallow water and light current; a 1/4-ounce head handles deeper water and stronger current. Pearl, chartreuse, and natural colors like mullet and shad patterns all produce. Keep a few topwater plugs for low-light conditions and calm water. Live shrimp under a popping cork works well for trout. Live mullet, either free-lined or under a cork, draws redfish and mackerel.

Avoid heavy sinkers and weighted rigs; they snag constantly on the rocks and waste your time. Keep your presentation simple: a jig head and soft plastic, or a cork and live bait. The current does the work for you.

Safety and practical details

The rocks are sharp and the current is strong. Wear cut-resistant gloves, long sleeves, and wading boots with good grip. Bring a first aid kit and know how to treat cuts from the rocks. The sun reflects off the water and rocks; wear sunscreen and polarized sunglasses to see the fish and protect your eyes.

The jetties are open to the public, but the area is active with commercial traffic and recreational boats. Stay aware of your surroundings and do not anchor in the shipping channel. If you are wading, stay close to the rocks and watch for boat traffic. The current can pull you away from the rocks if you lose your footing; a wading belt with a knife attached is good insurance.

Parking is available at the boat ramp near the jetties, but it fills quickly on weekends. Arrive early or plan to fish during the week. There are no facilities on the jetties themselves—bring water, snacks, and a headlamp if you plan to fish into the evening.

Frequently Asked Questions

Can I wade the north jetty?

No. The north jetty is steeper, deeper, and rockier than the south jetty. The current is faster and the rocks are unstable. Wading there is dangerous; use a boat instead.

What is the best tide for jetty fishing?

Incoming tide is best because it pushes baitfish toward the rocks and concentrates feeding fish. The two hours before and after low tide are safest for wading. High tide covers the rocks and spreads the fish into deeper water.

Do I need a boat to fish the jetties?

No. The south jetty is wadeable at low tide and produces redfish and trout. A boat lets you reach the outer rocks and the north jetty, where larger fish hold, but it is not required.

What size fish should I expect?

Redfish and trout average 15 to 20 inches on the south jetty. The north jetty and outer rocks hold larger fish, with redfish to 28 inches and trout to 24 inches. Spanish mackerel run 18 to 26 inches.

When is the slowest time to fish the jetties?

Winter (December through February) is slowest, but fish still bite on warmer days and during incoming tide. Fall and spring are most consistent. Summer is productive but requires early morning or late evening fishing to avoid the heat.
