When Blue Marlin Are Off Corpus Christi
Blue marlin are an offshore summer fish out of Corpus Christi, running July to September. Fishing for them means planning around those three months and a long run past the shelf structure. This page covers when to go, where the named structure sits on the run out, and where to read the rules. For the regional picture, see blue marlin across the Gulf of Mexico (see also the wider Gulf of Mexico guide).
Running Offshore From Corpus Christi
The run to marlin water goes past the nearshore reefs and the mid-shelf structure before it reaches bluewater. The Corpus Christi port page covers getting out of the port and the wider species picture.
The structure stacks up in a rough order as you leave the barrier islands:
- Nearshore reefs a few miles out
- Oil rigs in about 200 ft
- A mid-shelf bank
- Ranzels Rock, about 65 miles southeast
No NOAA buoy reports off Corpus Christi. Read the official National Weather Service marine forecast for wind, wave height and period before the run. Chart layers are not for navigation.
Named Grounds and Structure Off Corpus Christi
None of these is a named marlin ground. They are structure on the way out.
| Spot | Position | Depth |
|---|---|---|
| Corpus Christi Reef Site (TPWD nearshore reef) | State waters between Packery Channel and Port Aransas | 70 ft |
| Lonestar Reef | A few miles out from the barrier islands | |
| Boatmen’s Reef | A few miles out from the barrier islands | |
| Mustang Island-775 | Backup spot | |
| Ant Hills area oil rigs | Offshore rigs | about 200 ft |
| 29 Fathom Bank | Mid-shelf | |
| Ranzels Rock | About 65 miles southeast of Corpus Christi |
Corpus Christi Reef Site (TPWD nearshore reef)
This 160-acre TPWD nearshore reef sits in 70 ft of water, in state waters between Packery Channel and Port Aransas. Plot it on the TPWD Interactive Reef Locator.
Lonestar Reef
A nearshore reef a few miles out from the barrier islands. Treat it as a waypoint on the run.
Boatmen’s Reef
A nearshore reef a few miles out from the barrier islands.
Mustang Island-775
A backup spot only.
Ant Hills Area Oil Rigs
The rigs are fished in about 200 ft of water. They are rig structure on the way to bluewater.
29 Fathom Bank
A mid-shelf bank between the nearshore reefs and the deeper water beyond.
Ranzels Rock
About 65 miles southeast of Corpus Christi, it is the farthest named structure in the set.
How Blue Marlin Are Fished and Who Fishes for Them Here
Blue marlin from this port are an offshore summer target for anglers running bluewater. The blue marlin species guide covers trolling, tackle and biology.
Who Fishes for Them Here
Owner-operators running bluewater from this port. If you mix in other billfish, the billfish guides cover the rest of the group. The named structure here sits short of marlin water, so the main decision is how far past it to run.
