Full Moon Tides Reshape SF Bay and Bodega as Stripers Show South
Both NOAA CO-OPS stations covering San Francisco Bay and Bodega Bay are reading water in the mid-50s (55.8°F at station 9418767, 55°F at 9416841), with a high tide moving through late this evening ahead of a swift ebb toward a low near dawn. That swing lands on a full moon, so expect a stronger-than-usual push between high and low water. To the south, Western Outdoor News reports Allen Bushnell finding shoreline stripers holding tight to the Santa Cruz beaches this week, working the surf line behind bait and diving birds, the same fall pattern anglers working NorCal's inshore structure should be watching for.

The full moon's bigger tidal exchange should keep bait pushed tight against beach and rock structure through the overnight high and into the early low, making the pre-dawn ebb the window worth building a session around this week.
If the pattern Bushnell described near Santa Cruz holds, expect shoreline striper activity to keep tracking with the bait while water stays in the mid-50s; a sustained warm-up or cool-down would be the first sign that's shifting.
Weekend planning should center on the low-tide hours around dawn, with a tide swing of similar strength repeating on the same lunar cycle.
Context
Mid-to-upper 50s water in San Francisco Bay and Bodega Bay is typical for late September, as the region moves through its fall transition. Striper activity building along nearby beaches lines up with that shift, since baitfish push inshore ahead of cooling water and stripers follow them into the surf. Nothing here reads early or late for the calendar; it's an on-schedule fall pattern.
