Bay water holds mild as fall halibut and yellowtail talk builds
Water in the Bay is sitting in the mid 50s this week. NOAA CO-OPS station 9418767 read 53.8°F at 11:12 UTC, while station 9416841 read 57.2°F at the same time. That spread of a few degrees is the story for planning: the warmer water is where bait and active fish are more likely to hold, and the cooler reading marks water that may fish slower. Western Outdoor News — Saltwater describes a strong fall bite to the south, with a San Diego half-day crew trip crushing yellowtail before turning to white seabass. That is Southern California, not our region, but it shows the warm-water fish are still feeding on the coast this October. Treat it as a regional signal, not a local report.

Tides set the schedule for the next day or two. At station 9418767 the next low is 15:41 UTC (8:41 AM PDT) and the next high is 21:37 UTC (2:37 PM PDT). At station 9416841 the low comes at 14:53 UTC (7:53 AM PDT) and the high at 20:50 UTC (1:50 PM PDT).
Halibut typically set up on moving water near the edges of channels and flats, so the push of incoming tide after the morning low is a sensible window to plan around. Redfish are a Gulf species and not a local target, so skip them here. Expect the tide windows to slide roughly 45 to 50 minutes later each day.
The waxing crescent moon gives darker evenings, and with only a thin sliver of light the overnight and dawn periods should fish on tide timing more than on moon pull. If the water stays above 57°F at the warmer station, expect any warm-water visitors to linger. A cooling trend would push fish toward deeper, steadier water.
Check current state regulations before keeping any fish, since seasons and size limits change.
Context
Mid October in Northern California is a transition period. Summer upwelling fades, water tends to calm and warm slightly, and fall brings some of the most comfortable conditions of the year for inshore anglers. Halibut fishing typically remains productive into autumn as fish feed up on baitfish before winter. Readings in the mid 50s are in line with what we typically see at this point in the season, so the pattern looks on schedule rather than early or late.
