King mackerel fishing out of Port Mansfield, on the Texas coast, has a documented starting point: a run out through Mansfield Pass when the water is flat, and a charter that lists kingfish among its offshore targets. The king evidence is limited to one older magazine article and that charter’s own listing, so this page says where it is solid and where it is not. For the port itself, start with the Port Mansfield port page. For the wider coast, see the king mackerel fishing in the Gulf of Mexico and the wider Gulf of Mexico guide.
When king mackerel are around Port Mansfield
The blue-water season here runs from spring into November, but that is general wording about the water rather than a king-specific figure. The same account says kings get bigger as the water reaches the 80s in summer, which points to the warm months as the window for the larger fish. No month-by-month king season is documented for the port, so treat the warm months as the working window and check the water temperature before you go.
Where boats run
Mansfield Pass is the launch point and the first trolling area for kings when the water is flat, which means two feet or less. The Port Mansfield public reef, a state artificial reef site, lies about 7 nautical miles southeast of the jetties in about 70 feet of water. No king link is documented for that reef.
The harbor is reached through Port Mansfield Channel, a jettied, dredged entrance. Maintenance dredging has restored the channel to about 17 feet deep and 125 feet wide from the jetties through the harbor. Shoals in a sand-bottom inlet rebuild over time, though, so controlling depths at the jetty mouth may differ from charted figures. Southeast to east wind and swell can stack up at the jetty mouth on an outgoing tide, and strong north winds can put a cross chop in the channel. Check conditions yourself, and check recent dredging news before a deep-draft run.
Grounds and structure
Named structure is limited. Mansfield Pass and the channel jetties are the close-in water, and the public reef is the one named offshore site with a depth. Offshore, no named king ground is documented. Bamm Bamm’s own site describes offshore runs for kingfish and other species, but it names no reefs, depths or seasons.
How king mackerel are fished out of Port Mansfield
The documented method is bump-trolling with plugs or ribbonfish, as described by Capt. Chad Kinney. Bump-trolling keeps the lures working through the strike zone while the engine is kept just above idle and bumped in and out of gear. For live bait, the general Gulf approach applies, with a wire leader and a stinger treble, since kings cut monofilament. The run out through Mansfield Pass when the water is flat is the approach described for the port.
Who fishes it
Bamm Bamm Fishing Charters, run by Capt. Chad Kinney, lists kingfish among its offshore targets, along with dorado, wahoo, cobia, billfish and tuna. Its website is bammbammfishing.com. The site names no reefs, depths or seasons, so ask for those directly.
No king mackerel tournament is documented for the port. The port’s fishing tournament has an offshore division, but its species are not documented.
FAQ
Is Port Mansfield a good king mackerel port?
The port has a documented starting point for kings: a stated run out when the water is flat, and a named charter that lists kingfish. The evidence is still one older article and one charter listing, so treat the season and grounds as a starting point rather than a forecast.
What water conditions do I need?
The documented threshold is flat water, two feet or less. Check the marine forecast for wind and swell before you run out through the pass.
What gear do charters use for kings?
Bump-trolling with plugs or ribbonfish is the method described for the port. For live bait, use a wire leader and a stinger rig.
When do kings get bigger here?
The documented pattern is that they grow as the water reaches the 80s in summer.
