Midday tide window sets the pace on cold Gulf of Alaska water
Water reads 48°F at NOAA CO-OPS station 9455500 and 47.3°F at station 9452210, both taken this morning, so the cold-water fall pattern is in place along this coast. The timing that matters is the midday high: 11:11 AM AKDT at 9452210 and 12:34 PM AKDT at 9455500. Build your plan around that window, since moving water around the high tide is when fish tend to be most active.

Over the next two to three days, the signal to watch is whether water temperature holds in the upper 40s as daylight keeps shortening. A steady or slightly cooler reading means the same tide-driven plan still works. A sharp drop would push fish toward deeper, steadier water and shorten the productive window.
Check the marine forecast for wind before launching, because wind running against the tide is the factor most likely to change conditions on the water.
Context
Early October sits in the normal cooling phase of the Gulf of Alaska fall transition, and water in the upper 40s is consistent with that stage. Feeding activity usually concentrates in the windows set by tide and light rather than a steady all-day bite, and the seasonal decline in daylight shortens the prime hours. This is pattern-level context; the conditions on the day should decide the trip.
