Chinook salmon surge as NorCal coastal waters cool into prime range

What's Biting

What's Next

**Salmon and Nearshore Outlook — Next 2–3 Days**

With water at 51°F at buoy 46026 and northwest winds running at 3–6 m/s across both offshore stations, conditions look stable for coastal Chinook fishing near the SF Bay approaches and Bodega shelf. If the upwelling pattern holds — it historically tends to persist through late May and into June — the productive cool green water reported off Half Moon Bay should remain accessible, and may press further north toward the Bodega grounds.

The key daily window is first light through mid-morning. Afternoon northwest winds in this region routinely build and create uncomfortable chop offshore; plan your departure and return around the morning calm. Once the sea breeze pipes above 15–20 knots, the salmon bite typically shuts down and it's time to run for the harbor.

For offshore Chinook, trolling with anchovies or cut-plug herring in the cool, visibly distinct water remains the standard approach for this temperature band. Captain Davis (via Western Outdoor News — Saltwater) noted the color change in the water as a primary locator — that visible thermal break is worth working methodically when you find it.

The waxing crescent moon brings building tidal movement over the coming week as we approach first quarter. In the Bay, early-morning flood tides are a reliable trigger for striped bass pushing up into the shallows along rip lines near the Gate. California halibut should be staging on sandy bottom structure inside the Bay as water warms with the longer days — drift presentations with live bait or swimbaits over sand channels are the go-to approach.

No Bay or Bodega-specific field reports were available this cycle beyond environmental readings. Check in with local tackle shops before your trip for current bait availability — live anchovies and sardines for the Bay; fresh or frozen anchovies trolled for offshore salmon. Cold air temperatures near 10°C at buoy 46013 and persistent northwest winds are a reminder that NorCal coastal conditions can deteriorate quickly; file a float plan and check the marine forecast before departure.

Context

May is historically one of the top months for Chinook salmon along the NorCal coast, anchored by the annual upwelling cycle that drives cold, nutrient-rich water onto the shelf and concentrates baitfish within range of party boats and private anglers. The SF Bay bar and the Bodega shelf are classic spring salmon grounds, and conditions typically peak in May and June before stronger summer winds and heavier fog complicate access.

What makes this season worth watching is the early anomaly. Western Outdoor News — Saltwater reports that bonito — warm-water visitors not normally part of the NorCal spring picture — appeared briefly at the start of salmon season when temperatures ran near 58°F off Pigeon Point. That is well above the typical range for this coastline in April. The subsequent drop to 54°F, and now 51°F at buoy 46026 in mid-May, represents a return toward normal upwelling conditions — and the improving salmon bite Captain Davis described is the expected downstream effect of that correction.

A reading of 51°F in mid-May is at or slightly below the long-run average for this stretch of coast, suggesting the upwelling has been robust this spring. Salmon generally prefer water in the 50–56°F band; the current temperature is near the lower end of that window but historically productive for coastal trolling. The 10.1°C air temperature at buoy 46013 off Bodega is consistent with standard late-spring fog-belt conditions for the region.

No multi-year comparative data was available in this cycle's intel feeds to characterize the season as definitively early, late, or on schedule beyond what the Half Moon Bay report implies. The warm-then-cold pattern — an unusual early warmth followed by a cooling correction that improved the salmon bite — is a sequence NorCal regulars will recognize, even if its precise timing varies year to year.
