King Salmon and Halibut Season Ramps Up Across the Gulf of Alaska

What's Biting

What's Next

The most pressing factor shaping the next two to three days is sea state. NOAA buoy 46066 recorded 16.4-foot waves and winds of 15 m/s (roughly 29 knots) as of this morning, placing the outer Gulf firmly in rough-water territory. Buoys 46001 and 46080 paint a calmer picture at 8.9 feet and winds of 8-11 m/s, suggesting sheltered inshore zones and protected bays remain viable for small craft. Anglers planning offshore halibut runs should monitor NOAA marine zone forecasts closely and look for windows when winds ease below 15 knots.

Water temperatures of 42-44°F are cold but consistent with late May in the Gulf. As the season pushes toward June, surface temps typically begin creeping upward, pushing baitfish like herring and capelin into shallower nearshore zones. When bait moves in, king salmon follow, and trolling with herring rigs or spoons near structure and river mouths becomes increasingly productive. Late May into early June is historically one of the most dynamic transitions in the Gulf, as the season shifts from shoulder-period fishing to full prime-time activity.

The waxing gibbous moon, approaching full over the next few days, typically brings stronger tidal swings across the Gulf. Larger tidal exchanges concentrate baitfish on outgoing tides, which can fire up halibut and salmon activity near channels, drop-offs, and rocky points. Anglers targeting halibut should time their drifts along depth transitions during peak ebb tides, when forage species stack in predictable corridors.

For those willing to wait out offshore chop, a calming trend over the weekend is possible depending on North Pacific weather system timing. Check updated NOAA marine forecasts the evening before any offshore run rather than relying on the current swell snapshot.

Lingcod and rockfish require no special seasonal trigger and hold up well in the 42-44°F range. Vertical jigging with heavy jigs over reef edges and kelp lines is the standard approach, and these species provide reliable action on days when outer Gulf conditions keep halibut grounds out of reach. They also tend to be less weather-sensitive than offshore halibut, making them the practical default when swell height climbs above 8 feet.

Context

Late May marks the cusp of prime Gulf of Alaska season. Water temperatures in the 42-44°F range recorded across our three monitoring buoys are right on schedule for this time of year, with the broader warming trend that drives summer productivity still a few weeks out.

King salmon are historically in the early approach phase during the last week of May, staging offshore and near river mouths before pushing inward as June arrives. This window, before the heaviest run pressure builds, can produce quality fish for trollers working nearshore reefs and channel edges. King salmon availability typically increases noticeably through the first half of June if sea state cooperates.

Pacific halibut fishing in the Gulf typically peaks between Memorial Day and mid-July, when fish are accessible in moderate depths before summer heat pushes them into deeper water. The current offshore swell is a seasonal normal for late May, when North Pacific storm systems still push residual swell through the region. Several consecutive calm days often arrive in the first weeks of June.

AK Sea Grant's current reporting reflects an engaged and active Alaskan fishing community heading into the peak season, including last month's ComFish gathering at Kodiak. No current-season catch data or charter reports are flowing through regional intel sources today, so the species outlook above is grounded in typical seasonal patterns for the Gulf rather than verified angler testimony from the current week. If you have current intel from a local shop or charter, weigh that heavily alongside this report.
