NorCal Salmon Push Strengthens as Upwelling Cools Coastal Waters

What's Biting

What's Next

**Salmon: The Main Event**

The four-degree water temperature drop below Pigeon Point is the most actionable signal heading into the weekend. Captain Jared Davis of the Salty Lady told Western Outdoor News — Saltwater that the cooler 54°F water has meaningfully upgraded Chinook prospects compared to the slower bite at season opening in mid-April, noting that the water visibly "looks different" at that lower temperature. If the northwest wind pattern sustains through Sunday, expect the upwelling to continue refreshing coastal surface layers, keeping baitfish concentrated near thermocline edges and along the coast where Chinook stack up to feed.

For timing, the First Quarter moon produces moderate tidal movement rather than extreme swings, which can make for more consistent bite windows throughout the day rather than compressed feeding bursts around peak tidal transitions. Early mornings and late afternoons remain the standard salmon windows along this stretch; watch for bird activity over bait schools as a locating signal.

**SF Bay and Bay Mouth**

Striped bass in San Francisco Bay are moving into their late-May feeding patterns. No direct captain or shop intel surfaced this cycle for the Bay itself, but the seasonal window historically runs strong through June. Work structure edges, bridge pilings, and current seams at slack water on both incoming and outgoing tides. Live anchovy and sardines are the standard approach when available; swimbaits and topwater cover the dawn and dusk runs.

**Nearshore Rockfish and Bay Halibut**

We're seeing the kind of cooler, upwelled water column that generally produces for nearshore rockfish around Bodega Bay. Lingcod and cabezon hold tight to rocky structure; drift jigs and soft plastics work well across the 50 to 150-foot range. Check current state regulations for depth and species restrictions before targeting rockfish, as closures and bag limits vary by area and season. Bay halibut typically push onto sandy flats inside SF Bay and near the bay mouth through late May and June; drift presentations with live bait over sandy bottom are the standard go-to.

**Weekend Window**

Buoys 46026 and 46013 are both registering 3.6-foot seas with relatively light winds this morning, which represents workable conditions for offshore runs to the salmon grounds. Seas and wind can build through the afternoon as the coastal sea breeze fills in, so plan an early departure and monitor conditions before committing to a longer run south toward Pigeon Point.

Context

Late May sits at the heart of the spring Chinook salmon window along the NorCal coast, with the SF Bay area and Bodega Bay corridor historically among the most productive stretches on the West Coast from May through early July when upwelling is active and baitfish are abundant.

What makes this May notable is the broader context. Western Outdoor News — Saltwater reports that many Central Coast anglers "almost forgot what it is like to have a real salmon season," reflecting the cumulative weight of several restricted or closed seasons tied to low Sacramento River Chinook returns in recent years. The current improving picture, driven by the kind of northwest-wind upwelling event that historically concentrates salmon along the coast, represents a meaningful departure from that recent pattern. The four-degree cooling at Half Moon Bay mirrors the type of event that charter captains have long pointed to as the trigger for the spring bite.

The air temperature of about 51°F logged by buoy 46013 near Bodega Bay and the 3.6-foot swell across both nearshore buoys are consistent with typical late-May ocean conditions for this region: persistent northwest swell, cool marine air, and the afternoon sea breeze that characterizes late spring here. These are the surface expressions of an upwelling cycle that historically coincides with peak coastal salmon activity.

For SF Bay striped bass, late May is a transitional period in a typical year. Fish moving in from the Delta and Sacramento system push toward the bay mouth as water temperatures edge upward, and the surface bite on topwater and live bait generally peaks through June. No comparative data was available in current intel feeds to assess year-over-year variance in striper timing for this specific window.

No direct comparative data was available in current sources for local halibut or nearshore rockfish trends this cycle. The seasonal window and active upwelling align with conditions typical for this time of year, but specific year-over-year context for those fisheries would require additional local reporting.
