Gulf of Alaska water cools as fall pattern takes hold
Water across the two NOAA tide stations tracking this stretch of the Gulf of Alaska reads in the upper 40s this morning, 48.6°F at station 9455500 and 47.3°F at station 9452210, consistent with the seasonal cool-down now underway. Both stations are tracking toward an early-morning low and building to a midday high, the kind of window worth planning a trip around as daylight shortens into October.

Expect water temperatures to keep sliding through the week as nights lengthen and the Gulf moves deeper into its fall pattern. At station 9455500, the next low lands around 7:34 AM with high tide following near 1:53 PM; station 9452210 runs a touch earlier, low near 6:06 AM and high near 12:30 PM. That midday high window is the better bet for working structure before the tide starts dropping again in the afternoon.
With the moon in its waning crescent phase, tidal swings are moderate now but will build toward the new moon later this month. Anglers planning a weekend trip should watch for a stronger tidal push and more water movement as that approaches.
Context
Early October sits squarely in the Gulf of Alaska's transition from summer to winter patterns. Water temperatures in the upper 40s are typical for this point in the season as surface layers cool and mix toward winter stratification. This reads as an on-schedule seasonal shift rather than an early or late one for the region.
