Louisiana Gulf Hits 78°F: Inshore Bite Building Under Full Moon Tides

What's Biting

What's Next

The headline concern for the next 48–72 hours is the 6.2-foot wave heights logged by NOAA buoy 42001. Offshore anglers should monitor the marine forecast closely before committing to a run — seas at that height make bottom work on snapper and amberjack marks uncomfortable and potentially unsafe for smaller vessels. If the swell moderates to 3 feet or under (typical for the northern Gulf shelf as late-spring weather patterns stabilize), a window for nearshore and offshore action should open. At 78°F, Gulf surface temps are warm enough to hold cobia along floating structure and rig legs, king mackerel over hard-bottom humps, and early-season Spanish mackerel along nearshore color lines.

Inshore, the picture is more immediately accessible — and arguably more productive right now. Water at 78°F sits squarely in the comfort zone for speckled trout and redfish across Louisiana's bay systems and marsh complexes. Full Moon tidal flow running tonight through the weekend will push baitfish through tidal creeks and bay pass cuts, concentrating predators on the edges. These high-current exchange points are among the most reliable spots to find speckled trout on topwater plugs at first light.

Cobia are a legitimate weekend target. May is the peak window for sight-fishing cobia near Louisiana structure — channel markers, rig legs, and floating debris all concentrate them as surface temps climb. Full Moon conditions can trigger strong topwater feeding aggression. The pitch-baiting principle detailed by Saltwater Sportsman applies directly here: keep a rod rigged with monofilament (mono absorbs the shock of close strikes) ready at all times, and when a cobia surfaces near the boat or structure, pitch the bait and react immediately. Hesitation costs fish.

For the weekend overall: prioritize the two hours after first light and the two hours before dark for speckled trout on topwaters, using tidal current direction as your primary location indicator. For redfish, afternoon high tides pushing onto grass flats and oyster edges are historically productive. If seas calm by Sunday, a nearshore structure run to check for cobia is well worth planning around the morning tide window.

Context

For Louisiana's Gulf Coast and Mississippi River Delta complex, early May is traditionally among the most productive months of the year. Water temperatures in the central Gulf typically climb into the mid-to-upper 70s°F between late April and mid-May — the 78°F reading from buoy 42001 is right on schedule, neither running anomalously warm nor behind the seasonal curve.

Speckled trout are typically in a pre-spawn feeding push through May, staging in bays and along nearshore structure before moving to cleaner offshore water to spawn in late May and June. This window historically produces some of the largest trout of the year on surface lures worked in low-light conditions. Redfish follow a complementary pattern — flats-abundant and aggressive through May before summer heat disperses them into deeper, shadier channels and shell ridges by July.

The snook expansion documented by Field & Stream near Pascagoula Bay fits into a multi-year Gulf trend that Louisiana anglers on the state's eastern coast should note. Snook have historically been limited to Florida and Texas waters, but warming Gulf baseline temperatures are steadily pushing their range northward and westward along the northern coast. This is a trend to track, not a reason to target snook specifically — and anglers should verify current Louisiana state regulations before keeping any unfamiliar catch.

No year-over-year comparative data from Louisiana charters, state agencies, or local shops is available in today's feeds to benchmark this May against recent seasons with any precision. The species statuses in this report reflect seasonal norms and real-time buoy conditions rather than confirmed on-water catches. Local intel from coastal marinas and tackle shops will provide a sharper read before you launch.
