When mahi are around South Padre Island
Reel Madness runs its shrimp-boat trips for mahi July through November. Osprey lists mahi in the warmer months. Dorado is a category in the September SPI Wahoo Classic.
These are operator schedules and a tournament category, so they show when local boats target dorado but say nothing about what any given day will deliver. The Gulf-wide pattern behind this window is covered in the Gulf of Mexico mahi pattern (see also the Gulf of Mexico region guide) guide.
Planning signals at a glance:
- July through November: Reel Madness shrimp-boat trips
- Warmer months: Osprey’s listing for mahi
- September: dorado category in the SPI Wahoo Classic
Where boats run and the structure along the way
Mahi-mahi fishing out of South Padre Island starts with a run through Brazos Santiago Pass to three targets: deep-water shrimp boats, blue water off the shelf and the Texas FADs. The mahi-mahi species guide carries the general biology and tackle. This page covers what is specific to the South Padre Island port: when the fish are around, the named structure, how locals fish it and who runs these trips. It lists places to look and makes no promises of fish.
The continental shelf starts to drop around 30 miles offshore, and the blue water past it is mahi water. That makes this a long-range trip for anglers running their own boat. The nearshore reefs are waypoints on the run, and we make no catch claims for them.
| Ground | Depth | Distance |
|---|---|---|
| Brazos Santiago Pass jetties (North and South) | Flank the pass entrance | |
| Port Isabel Reef | 75 ft | |
| Texas Clipper | 134 ft | About 17 nm |
| RGV Reef | ||
| Continental shelf edge | Starts to drop around 30 miles | |
| Texas FADs (Hilton / HBGFC buoys) | About 1,300 ft | |
| Deep-water rigs, incl. Perdido |
Charted positions are for planning, not for navigation. Read wind, wave height and period at BZST2 before the run, then check the NWS Lower Texas coastal forecast.
Brazos Santiago Pass jetties
The North and South jetties flank the pass entrance to the Gulf. Every run from this port starts here.
Port Isabel Reef
Port Isabel Reef sits in 75 ft and is a waypoint on the run.
Texas Clipper
The Texas Clipper sits in 134 ft, about 17 nm off South Padre Island.
RGV Reef
RGV Reef is named structure off the port.
Continental shelf edge
The shelf starts to drop around 30 miles offshore. Blue water lies past it, and that is where boats troll.
Texas FADs
The Texas FAD network is the Hilton and Houston Big Game Fishing Club buoys, in about 1,300 ft.
Deep-water rigs and Perdido
Deep-water oil rigs, Perdido among them, are structure for longer runs.
Deep-water shrimp boats
Deep-water shrimp boats are a local mahi target. The drifting method is described in the next section.
How mahi are fished from this port
Two methods carry the local fishery: trolling the blue water and drifting around shrimp boats. Rigging and baits are in the species guide.
- Trolling the blue water: Boats cover ground off the shelf, past the drop around 30 miles out, and look for fish.
- Drifting around shrimp boats: Boats work deep-water shrimp boats by drifting around them. Reel Madness schedules this method July through November.
Who fishes for them out of South Padre Island
Five South Padre Island charters list mahi-mahi among their targets:
- South Padre Island Sportfishing (REEL Madness): 38 ft sportfisher, up to 6 passengers, Captain Todd Lohry
- Texas Sportfish charters (Miss Directed / Miss Guided)
- SaltWalker Sport Fishing Charters: Captain Michael Walker, based at Sea Ranch Marina
- Epic Charters Unlimited: Captain Roy Songy
- Osprey Cruises deep-sea trips (Osprey II): 70 ft
The same boats target wahoo and other offshore gamefish.
