Mississippi Sound Hits 76°F With Spanish Mackerel Push Imminent

What's Biting

What's Next

**Conditions over the next 2–3 days**

With surface temps at 76°F and light wind today, the Mississippi Sound should remain hospitable through the coming weekend barring an unseasonal front. The temperature stack — air at 75°F, water at 76°F — suggests any passing front would be mild at worst. If winds stay near today's 3 m/s reading from buoy 42067, glass-calm mornings on the Sound are possible, which opens up sight-casting opportunities along the shallower grass-flat edges.

The waxing gibbous moon reaches full phase in roughly two days, pushing tidally driven feeding windows to their monthly peak. For inshore anglers, that means stronger outgoing and incoming rips through the barrier-island passes and around oyster-reef edges. Target the 90-minute windows on either side of a tide peak for the most reliable shots at speckled trout and redfish holding current seams.

**What should turn on**

Spanish mackerel are the headline event to watch. These fish typically stage near the Chandeleur Islands and the barrier island chain once Sound surface temps clear 73–75°F, and today's 76°F reading puts conditions squarely in that trigger window. Saltwater Sportsman's pitch-baiting coverage is worth revisiting before you launch: when mackerel push baitfish to the surface, pitching a topwater popper or a lightly rigged live cigar minnow into the breaking fish outperforms dragging a trolling spread — faster presentation, cleaner hookups in close quarters.

Flounder should be transitioning along near-shore sandy drop-offs as spring movement picks up. A slow-rolled soft-plastic paddletail worked along bottom transitions produces consistently when water clarity is good.

**Weekend timing**

Plan a pre-dawn departure to catch first light alongside an incoming tide. With the moon nearing full and light winds in the forecast, a two-to-three-hour morning window before midday heat builds will be the prime slot Saturday and Sunday. Bring sun protection — mid-70s air temps under open Gulf sky feel considerably hotter on the water, and the UV index this time of year is high by 9 a.m.

Context

Late April in the Mississippi Sound typically sees water temperatures in the 68–74°F range, so today's 76°F reading from buoy 42067 sits on the warm end of the historical envelope for this date. An early-warming spring like this accelerates several key patterns: speckled trout that ordinarily peak on grass flats in early May can show up a week or two ahead of schedule, and the Spanish mackerel migration — normally a mid-May story across the central Sound — may arrive earlier if the warmth holds into the first week of May.

No comparative signals from Mississippi charter captains or local tackle shops appear in this week's angler-intel feeds to confirm or contradict the pace-of-season read, so the assessment above is temperature-based inference rather than direct on-the-water testimony. That gap is worth flagging honestly: if you hit the Sound this week, your own report is more current than any aggregated source available here.

Historically, the late-April Mississippi Sound bite organizes around three rhythms: speckled trout staging along Biloxi Marsh grass edges before summer heat pushes them to deeper structure; the first flush of Spanish mackerel arriving off the barrier islands; and resident redfish that hold bridges, passes, and oyster reefs year-round. All three patterns are consistent with a 76°F water reading. The waxing gibbous moon is seasonally normal for late April and adds a favorable tidal-activity layer on top of the warming trend — a combination that, in a typical year, marks the unofficial start of the Sound's most productive inshore window.
