Cooling water sets up fall transition around SF Bay and Bodega
Water temperatures along the SF Bay and Bodega stretch are sitting in the mid-50s this week, with our two tide stations reading 54.9°F and 56.3°F as of late morning today (October 10). That's typical cooling for the shift into mid-fall, arriving alongside a new moon, which tends to sharpen tidal exchange and current speed through the Bay's channels and around Bodega Head. High tide builds through late morning into early afternoon at both stations, roughly 11:11 AM and 12:03 PM respectively, giving anglers a clean window to work the push before the afternoon ebb sets in.

Expect water temps to hold steady or ease slightly over the next few days as the region settles into its typical fall rhythm; the current readings don't point to a sharp swing either way. The new moon phase through the weekend means stronger-than-average tidal flow, which is worth building a trip around: the last two hours of the incoming tide and the first hour of the outgoing tend to concentrate activity around current seams and structure. With high tide landing close to midday at both stations, late-morning starts line up well with the strongest push this weekend.
As cooling continues into late October, anglers working the Bay and the open coast near Bodega should watch for water to ease further into the low 50s, the kind of shift that typically marks the next seasonal turn along this stretch.
Context
This tracks right on schedule for Northern California's fall pattern, when water in the Bay and along the open coast near Bodega steadily cools from summer highs into the low-to-mid 50s through October and November. New-moon tide cycles like this one are a reliable seasonal marker for stronger current days. Nothing in the current readings suggests an early or late transition compared with a typical year for this stretch of coast.
