Spring Halibut and Salmon Seasons Open in the Gulf of Alaska

What's Biting

What's Next

**Conditions over the next 2–3 days**

With buoy 46080 already nudging 44°F and the two outer-Gulf stations sitting at 40°F, a modest warming gradient appears to be in place from nearshore to offshore. Light winds of 2–5 m/s across all three NOAA buoy stations suggest a relatively settled early-May weather pattern, though the Gulf of Alaska can shift quickly—always pull a current NOAA marine forecast before departure, particularly if running more than a few miles from port. Wave height data was unavailable at all three stations at report time, which limits sea-state assessment; check buoy 46001 and 46080 in real time for an updated swell picture before committing to an offshore run.

**What should turn on soon**

Pacific halibut is the primary focus for Gulf anglers this time of year. As bottom temps stabilize in the low-to-mid 40s, halibut feeding activity typically picks up on sand-and-mud transition zones in the 200–400 ft range. Whole herring on large circle-hook rigs fished on the bottom remains the traditional and reliable approach; drift-fishing over known offshore flats tends to be most productive when tidal current is minimal.

Rockfish and lingcod remain available on nearshore structure throughout spring regardless of temperature swings. Lingcod in particular can be aggressive as water eases into the low 40s—heavy jigs and large swimbaits worked along rocky drop-offs are standard producers this time of year and worth targeting on any trip that ventures near structure.

King salmon (Chinook) returns to Gulf drainages are the wildcard of the spring. Early-season kings often stage near river mouths and offshore reefs in May, but run timing and open areas vary significantly by drainage and management unit. Verify current area-specific openings before targeting them.

**Weekend planning windows**

Light winds and relatively calm conditions point to a potentially fishable offshore weekend. The waning gibbous moon produces moderate tidal exchanges—target the two hours before and after each major tide swing for the most active bite windows on halibut and bottom species. Early-morning departures ahead of afternoon sea-breeze development remain the safest and most productive practice in the Gulf of Alaska throughout May.

Context

Early May in the Gulf of Alaska typically marks the transition from the slow late-winter period into the most productive inshore and nearshore season of the year. Buoy readings of 40–44°F are consistent with historical norms for this region at this time—surface temps in the Gulf generally run between 38°F and 46°F through May, slowly trending upward toward the mid-50s by midsummer. There is nothing in the current buoy data to suggest conditions are running notably early or late; the thermal picture looks on-schedule for a standard spring startup.

The Pacific halibut season, set annually by the International Pacific Halibut Commission, typically opens in spring and runs through late fall, with the busiest charter activity concentrated from May through September. Early-season halibut are often found slightly deeper than midsummer fish as they follow baitfish schools moving up from winter holding depths—an important tactical distinction for anglers transitioning from shallower summer structure.

King salmon return timing in the Gulf varies considerably by drainage. Some systems see early-run kings beginning to stage nearshore in April and May; others peak in June or July. In several Gulf drainages in recent years, run forecasts have come in below long-term historical averages, making current-season management advisories especially important before planning a dedicated Chinook trip.

No angler-intel sources in our current feeds contained Gulf of Alaska–specific field reports for this period, so no direct comparison to how this season is tracking relative to prior years is possible from the available data. The environmental readings alone—light winds, cold but seasonally normal surface temps, no anomalous thermal signals—suggest a routine early-May opening rather than anything that would cause concern or excitement on the seasonal-timing front.
