73°F Gulf Water Primes Mobile Bay for Peak May Fishing

What's Biting

What's Next

Our current readings — 73°F water at buoy 42012 and light 3–4 m/s winds at both nearshore stations — suggest a comfortable few days ahead for bay and inshore anglers. Wave-height data was unavailable from either buoy this cycle, so those planning longer offshore runs to the rigs should pull a current marine forecast on the morning of departure.

Cobia migration is the marquee story for early May in Alabama Gulf waters. Fish are typically moving through the nearshore zone now, tracking rays and other large marine life along channel edges and the shipping lanes approaching Mobile Bay Pass. Given the stable wind profile and comfortable water temperature, the next 2–3 days look favorable for sight-fishing cobia from the bow. Early mornings — before any afternoon sea breeze builds — will offer the clearest sight-fishing conditions and the best window for presenting a live bait or pitch-bait to a cruising fish.

Speckled trout on the grass flats should respond well to the waning gibbous moon, which drives moderate tidal movement overnight and into dawn. Coastal Angler Magazine advises shifting toward a second-shift pattern as the season transitions: load the boat in the late afternoon, hit the flats during the last two hours of daylight, and fish into the evening when trout move shallow to feed aggressively. This approach becomes increasingly productive as May advances and midday surface temps climb.

Spanish mackerel should also be rolling along the beaches and nearshore structure. Look for bird activity and surface breaks as mackerel push bait toward the surf zone; casting spoons or trolling a small feather in the top 10 feet has historically been effective during this window.

Redfish action in the back bays and along marsh edges typically holds steady through this period, with warming temps keeping fish active in the shallows during low-light hours. Field & Stream reported in late April that snook are expanding their range toward the Pascagoula Estuary just east of the Alabama border — a range expansion worth monitoring if it continues westward in future seasons.

Context

For Mobile Bay and the Alabama Gulf Coast, early May historically represents one of the strongest stretches of the fishing calendar. Water temperatures in the 70–75°F band — where we're sitting now at 73°F per NOAA buoy 42012 — are right on track for a normal seasonal progression. In a typical year, this temperature range signals the peak of the cobia migration, the height of the Spanish mackerel run along the beaches, and reliable speckled trout action before summer heat drives fish deeper and makes midday fishing less productive.

Cobia are Alabama's signature May target, and the timing of their nearshore migration is closely tied to water temperature. At 73°F, fish should be in full transit along nearshore structure, making this the window most experienced Gulf anglers plan their season around. Years when water temps reach the low-to-mid 70s by the first week of May tend historically to produce the strongest cobia numbers before fish scatter to offshore structure later in the month.

Field & Stream noted in late April that snook are establishing a presence in the Pascagoula Estuary east of Biloxi Harbor — a species historically absent from these waters. This northward range expansion is consistent with warming Gulf trend lines and worth tracking; it may represent future inshore opportunity along Alabama's western coast, though snook are not yet a reliable target in Mobile Bay.

No state agency or local charter reports were included in this cycle's intel feed specific to Alabama, limiting direct comparison to prior-season bite reports. On the environmental side, current conditions appear on schedule for a normal May pace — water temperature and wind patterns show no anomalies that would suggest early or delayed species arrivals. Treat species-status assessments here as seasonal baselines, and update them with local intel gathered at the ramp or from tackle shops before heading out.
