Red snapper fishing out of Biloxi means running past the Mississippi barrier islands to artificial reefs, wrecks and oil rigs, with local trips typically falling in June and July. This guide covers when the fish are around, how far boats run, the grounds and structure that hold snapper, how snapper are fished locally and who fishes these waters. It is written for anglers running their own boat. Ship Island, Horn Island and Cat Island shape the route, and state waters end 9 nautical miles south of the islands. For the whole coast, see the Gulf of Mexico fishing guide.
When red snapper are around Biloxi
Fish-On says its snapper trips are typically June and July, so that is the window to plan around.
Spring has its own barrier-island fishery. Cobia work the Cat Island and Horn Island grounds in late April and early May, ahead of the snapper trips. That pattern belongs to cobia and doesn’t apply to snapper.
For the species itself, see our guide to red snapper in the Gulf.
| Fishery | Where | Timing |
|---|---|---|
| Red snapper | Reefs, wrecks and rigs past the barrier islands | Typically June and July (Fish-On) |
| Cobia | Cat Island and Horn Island grounds | Late April and early May |
How far boats run from Biloxi

Fish-On says boats run past the barrier islands to artificial reefs. SYL lists wrecks and oil rigs off Biloxi. The Biloxi port page has the passes, ramps and local conditions notes for getting out.
The Mississippi DMR places state waters 9 nautical miles south of the barrier islands. For-hire boats with state permits fish inside that line.
The runs fall into three tiers:
- Barrier-island structure. Horn Island Bar is a short boat trip from Biloxi.
- 15 to 20 miles out. The wrecks around Ship Island and the Camille Cut tanks and barges sit about 15 to 20 miles offshore.
- Long range. The Horseshoe rigs and salt domes south of the Mississippi River mouth, and the Ram Powell rig off Louisiana.
Check buoy 42040 before the run

NDBC notes that station 42040 was re-established about 60 NM south of 42007’s nominal position. Its readings describe water far offshore of the barrier islands, not the passes or Mississippi Sound.
Read wind, wave height and dominant period at 42040 alongside the official marine forecast, then compare both with what you expect in the Sound and at the pass.
Grounds and structure off Biloxi

Biloxi snapper structure falls into four groups: barrier-island structure, MDMR reef sites, wrecks and tanks 15 to 20 miles out, and deep long-range rigs. Chart layers such as Chart Contours help you locate structure but are not for navigation.

| Katrina Reef | Inshore, Biloxi area | – |
| Horn Island Bar | South side of Horn Island, a short boat trip from Biloxi | – |

| Ship Island wrecks, Camille Cut tanks and barges | Offshore | About 15 to 20 miles |
| Horseshoe rigs and salt domes | South of the Mississippi River mouth | 300 to 400 ft |
| Ram Powell rig | Oil rig off Louisiana | – |
| Offshore ledge | – | – |
