Salmon Surge as NorCal Coast Cools Into Prime Conditions

What's Biting

What's Next

The northwest wind pattern driving coastal upwelling shows no sign of breaking in the near term. With buoy 46026 registering 53°F and buoy 46013 recording 10 m/s sustained northwest winds, surface temps along the outer coast should hold in the 53–55°F band that Chinook salmon prefer, keeping baitfish concentrations productive around thermal breaks. Captains working the waters below Pigeon Point and the Half Moon Bay corridor — as described by Western Outdoor News — Saltwater — have been targeting the cooler, greenish-blue color change offshore, and that defined temperature break should stay in place heading into the first days of June. If winds briefly ease midweek, expect a temporary flush of warmer surface water before the next northwest event re-establishes the upwelling pattern.

Full moon conditions this weekend generate the largest tidal exchanges of the month. In San Francisco Bay, the outgoing tide accelerating through the Gate produces current seams and rip lines where striped bass traditionally concentrate. Outgoing tide at first light is the window to prioritize — work the points and channel edges where current accelerates. Full moon typically pushes bass feeding into the early-morning and late-evening hours; midday midtide windows tend to go quiet. Larger tidal swings also benefit halibut anglers drifting live anchovies or sardines over the sandy flats in the shallower reaches of the Bay.

For salmon heading offshore, trolling cut-plug herring or spoons in the 30–60 foot range is a sound starting depth when surface temps are running in the low-to-mid 50s. Work temperature breaks rather than fixed GPS waypoints — upwelled water moves targets daily, so follow your sonar and watch for bird activity over bait schools. Early-morning departures from Half Moon Bay and Bodega Bay typically reach productive grounds before afternoon winds kick up. If northwest winds ease below 8 m/s this week, the nearshore reef structure from Bodega Head south to Point Reyes should open up for quality rockfish action. Verify current Rockfish Conservation Area boundaries and depth limits before departing, as restrictions apply broadly in this zone.

Context

Late May typically marks the transition into the most productive stretch of Northern California's salmon season. Once consistent northwest winds establish the upwelling cycle — usually by mid-May — water temps along the outer coast fall from spring highs into the 50–55°F band that concentrates baitfish and draws Chinook to workable depths. The current 53°F reading at buoy 46026 puts conditions squarely on that historical schedule.

What makes 2026 notable is the contrast with recent seasons. Western Outdoor News — Saltwater contributor Allen "Bushy" Bushnell notes from Monterey that many local anglers had "almost forgot what it is like to have a real salmon season along the Central Coast" — a candid acknowledgment that recent seasons underperformed relative to historical norms, likely tied to warmer ocean conditions. The upwelling-driven cooling now underway represents a meaningful course correction, and current buoy readings combined with the Half Moon Bay charter reports suggest this year is trending ahead of those recent warm-water benchmarks.

For striped bass in San Francisco Bay, full moon in late May has historically aligned with the peak spring push. Bass that staged through the Delta and Central Valley river systems during winter typically concentrate in the Bay's main channels and around the Golden Gate through April and May, with trophy-class fish accessible through June. This report lands squarely in that window. Halibut are also seasonally consistent in the Bay during late spring, though no direct intel is available this week to confirm current bite conditions — treat them as a standard late-May option rather than a confirmed hot target until fresh reports emerge from local captains or tackle shops.
