Mississippi Sound shrimping opens wider as redfish stay in play
Mississippi Sound anglers get a notable change this week as MS DMR announced a conditional opening of additional Biloxi Bay waters to shrimping on October 15. The order covers waters south and west of a line running from Beacon 18 to Beacon 26 in the Biloxi Bay Channel, then on to Beacon 34 and Beacon 30, exclusive of the Biloxi Channel itself. It adds to the waters opened May 26, 2026, so check the full order and chart before running any gear. Water is warm for mid-October. NOAA CO-OPS station 8747437 read 80.4°F and station 8741533 read 79.7°F at 17:06 UTC today. That is summer-like temperature for the Sound, and it keeps bait and gamefish active in the shallows. On the fish side, the clearest redfish signal in this week's feeds comes from Coastal Angler Magazine, which carried a reader photo of a 28.5 inch bull redfish caught in the shallows on October 5. That catch was on the Gulf coast of Florida, not Mississippi, but it shows the fall shallow-water redfish pattern is underway across the Gulf. We would treat it as a pattern indicator for the Sound rather than a local report.

What's next
Expect the warm water to hold through the weekend, with readings staying near 80°F at both tide stations. That favors an early-morning and late-afternoon bite in the shallows, when redfish typically push onto flats and along marsh edges to feed. Midday heat tends to slow things down, so plan the best window around first light.
Tide timing matters today. Station 8741533 shows its next low at 17:59 UTC, which is 12:59 p.m. Central, and station 8747437 shows its next low at 19:51 UTC, or 2:51 p.m. Central. Falling water toward those lows can concentrate bait along channel edges and drop-offs, and the incoming tide that follows is a reasonable window for working shallow structure. Local timing at the second station runs about two hours behind the first, so adjust if you are fishing between the two.
The waxing crescent moon means darker evenings, so dawn will be the cleaner light window for sight casting. Anglers who also shrimp should note that the new conditional opening in Biloxi Bay is likely to put more boats on the water and more activity around the beacons named in the order. Give working boats room and keep clear of the Biloxi Channel itself, which the order excludes.
As always, confirm current rules before harvesting. Seasons, limits and area openings change by order, and the MS DMR notice is the authoritative reference for the shrimping boundary.
Context
Mid-October in the Mississippi Sound sits in the fall transition. Water that is still near 80°F is on the warm side of typical for this time of year, and cooling typically arrives gradually through November. Until it does, shallow-water fish tend to keep feeding aggressively, and the fall baitfish movement along the Gulf coast generally continues to draw predators close to the shoreline.
Redfish are a staple of this season. Fall is commonly considered one of the more productive stretches for them, as fish feed up ahead of colder weather. Over the coming weeks, a cooling trend usually shifts the pattern toward slower presentations and deeper holes, but that shift has not shown up in this week's water temperatures.
Shrimp season activity is also a seasonal marker. Additional waters opening after sampling signals that shrimp are sizing up inside the bay system, and where shrimp go, predators tend to follow. This is general seasonal context, not a report from any specific water.
