Where Spanish mackerel are caught out of Galveston

Spanish mackerel fishing out of Galveston is a summer jetty fishery: live shrimp, free-lined along the rocks, with half-day boats running 10 to 40 mi when the fish spread out. The ground that matters most is the entrance channel to Galveston, flanked by the north jetty at Bolivar and the south jetty at Galveston Island. This page covers when the fish are around, the grounds by distance, how the jetty bite is fished, and which buoy to read before you run.
The jetties
The north jetty at Bolivar and the south jetty at Galveston Island both stand at the entrance channel and are the primary local ground for Spanish mackerel. Fish both of them.
Half-day range
According to Sea Ventures, half-day trips out of Galveston run 10 to 40 mi. That is the working range beyond the rocks when the fish are not on the jetties.
When Spanish mackerel are around Galveston

Summer is the season. An August Daily News report put Spanish mackerel at the jetties. Sea Ventures lists them spring through fall on half-day trips, so the charter window is wider than the summer core.
The Gulf-wide migration picture (see also the Gulf of Mexico fishing guide) is covered in our regional guide, which explains how the fish move along the coast.
Grounds and structure off Galveston

The grounds below are listed from nearest to farthest from the jetties.
| Ground | Direction / distance from the jetties | Depth |
|---|---|---|
| Galveston jetties (north at Bolivar, south at Galveston Island) | At the entrance channel | 24-28 ft where bull reds were taken |
| 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 | 30-60 mi | |
| Flower Garden Banks | 90-110 mi offshore | 200-1000+ ft |
| Nansen oil rig | 100-130 mi |
Galveston jetties
The jetties sit at the entrance channel. The 24-28 ft figure comes from where bull reds were taken, so use it as a depth reference for the rocks rather than a mackerel depth.
Big Man’s and Kate’s Nearshore Reefs
Both reefs lie roughly 20 mi southwest of the jetties. Plot exact numbers on a chart before you run; chart layers are not for navigation.
Cerveza rig
The Cerveza oil rig sits due south of the jetties.
Wrecks and rigs, 30-60 mi
Wrecks and rigs between 30 and 60 mi make up the structure band inside the half-day run range.
Seawall piers
The 61st Street and 91st Street piers are pay piers on the Galveston seawall, the land-based option on the same water.
Farther offshore
The Flower Garden Banks are 90-110 mi out, in 200-1000+ ft. The Nansen rig is 100-130 mi out and is a yellowfin night trip. Offshore boats go to these places for other species, not for mackerel, and they show how far the Galveston fleet can run. Those runs are covered under other coastal and offshore gamefish.
How Spanish mackerel are fished out of Galveston

At the jetties, Spanish mackerel are fished with live shrimp, free-lined, per guide reports. For general tackle and behavior, the species guide covers rigging.
Live shrimp at the jetties
Guide reports describe live shrimp as the jetty bait.
Free-lined bait
Bait is free-lined at the jetties, with no weight to pin it to the bottom.
Reading conditions before the run
NDBC 42035 sits 22 NM east of Galveston, at 29.235 N 94.410 W. Check wind, wave height and period on NDBC Station 42035 readings, then read the Houston/Galveston NWS marine forecast before you leave the dock.
The buoy sits 22 NM east of the jetties, not at them, so treat its numbers as a read on the nearby Gulf and check the water yourself once you clear the rocks.
Who fishes them from this port
Galveston Sea Ventures lists Spanish mackerel, and its Galveston Sea Ventures half-day trips run 10 to 40 mi. Capt. Shane is named in a Sea Ventures review.
FAQ: Spanish mackerel fishing out of Galveston
When are Spanish mackerel at the Galveston jetties?
Summer is the season. An August Daily News report had them at the jetties. Sea Ventures lists them spring through fall.
How far do boats run for Spanish mackerel out of Galveston?

What bait is used for Spanish mackerel at the Galveston jetties?
Guide reports describe live shrimp, free-lined.
Which buoy should I check before running out of Galveston?
Check NDBC 42035, 22 NM east of Galveston, for wind, wave height and period, alongside the NWS marine forecast. It is not at the jetties.
Can I fish from the Galveston piers instead of a boat?
The 61st Street and 91st Street piers are pay piers on the seawall, on the same water. They are the land-based option, and no catch is promised.
