Where gag hold off Galveston and how far boats run

Gag grouper fishing out of Galveston means running past the jetties to deeper structure. Every distance on this page is measured from the Galveston jetties, the zero point for the run. Get Hooked names gag among the groupers it fishes and places them on reefs, wrecks and artificial structure in deeper water. Other Galveston charters list "grouper" without naming the species. The same fishery along the rest of the coast is in the Gulf of Mexico offshore fishing guide.
The working band is the wrecks and rigs at 30 to 60 mi. The Flower Garden Banks, at 90 to 110 mi, mark the far ceiling. The jetties and the seawall piers are where the port starts, and they are not gag grounds. For the wider Gulf picture, see our reef fish guides.
- Structure type: reefs, wrecks and artificial structure in deeper water
- Working band: 30 to 60 mi from the jetties
- Far ceiling: 90 to 110 mi, the Flower Garden Banks
Named grounds from the jetties out

The grounds below run from closest to farthest, measured from the jetties.
| Ground | Distance and bearing from the jetties | Depth |
|---|---|---|
| Galveston jetties (north at Bolivar, south at Galveston Island) | At the entrance channel | 24 to 28 ft |
| Big Man’s Nearshore Reef | Roughly 20 mi southwest | |
| Kate’s Nearshore Reef | Roughly 20 mi southwest | |
| Cerveza oil rig | Due south | |
| Wrecks and rigs | 30 to 60 mi | |
| Flower Garden Banks | 90 to 110 mi (Get Hooked) | 200 to 1000+ ft |
| Nansen oil rig | 100 to 130 mi | |
| 61st Street and 91st Street seawall piers | On the Galveston seawall |

Galveston jetties
The north jetty is at Bolivar and the south jetty is at Galveston Island. Both flank the entrance channel, in 24 to 28 ft, where bull reds have been taken. Every run out of the port starts here.
Big Man’s and Kate’s Nearshore Reefs
Both reefs sit roughly 20 mi southwest of the jetties and are the first named structure on the way out.
Cerveza rig
The Cerveza oil rig sits due south of the jetties.
Wrecks and rigs, 30 to 60 mi
This band matches where gag hold: wrecks and artificial structure in deeper water. It is the realistic run distance for this kind of structure out of Galveston, and it answers the question of how far to go.
Flower Garden Banks
The Flower Garden Banks lie 90 to 110 mi offshore in 200 to 1000+ ft, per Get Hooked. They are the ceiling on run distance from this port.
Nansen rig
The Nansen rig sits 100 to 130 mi out and is a yellowfin night run.
Seawall piers
The 61st Street and 91st Street piers are pay piers on the Galveston seawall. They are shore-side context for the port.
How gag are fished here
Locally, gag are fished by bottom fishing over the deeper structure covered above. For biology, tackle, depth and behavior, read our gag grouper guide.
Reading conditions before the run

Whether a run goes depends on wind, wave height and period, not on a date. The nearest buoy is NDBC 42035, 22 NM east of Galveston at 29.235 N 94.410 W. Check the NDBC station 42035 readings for those three numbers before you leave the dock.
The 30 to 60 mi and 90 to 110 mi runs put more water between you and the jetties, so those numbers decide how far you go. Read them against the Houston/Galveston coastal marine forecast. The forecast tells you what is expected, while the buoy shows what the water is doing at the moment you read it.
- Wind: read the speed and direction at the buoy
- Wave height: read it at the buoy, then check it against the forecast
- Period: read it alongside height
Who fishes for gag out of Galveston
Get Hooked is the Galveston charter that names gag. Other Galveston charters list grouper without naming the species, so most grouper listings will stop at that word.
FAQ about gag grouper fishing out of Galveston
How far do boats run for gag from Galveston?
Boats run 30 to 60 mi to wrecks and rigs, measured from the jetties. The Flower Garden Banks, at 90 to 110 mi, are the far end of the range.
Do the nearshore reefs or the jetties hold gag?
The sources tie gag to reefs, wrecks and artificial structure in deeper water. The jetties, at 24 to 28 ft, are port context, and bull reds are the fish taken there. Big Man’s and Kate’s reefs sit roughly 20 mi southwest of the jetties.
How far are the Flower Garden Banks?
They lie 90 to 110 mi offshore in 200 to 1000+ ft of water, per Get Hooked, which makes them the longest run named for gag from this port.
Which buoy should I check?
Check NDBC 42035, 22 NM east of Galveston at 29.235 N 94.410 W. Read wind, wave height and period, then compare them with the official marine forecast.
Which charters target gag?
Get Hooked names gag. Other Galveston charters list "grouper" without naming the species.
