Central Coast Chinook Season Surges as Upwelling Takes Hold

What's Biting

What's Next

The upwelling pattern that dropped nearshore temperatures four to five degrees over the past week is the key variable heading into the Memorial Day weekend. As northwest winds continue pushing surface water offshore and drawing cold, nutrient-dense water up from depth, the salmon bite should remain active along the Central Coast corridor from Half Moon Bay south to Monterey and Santa Cruz.

Western Outdoor News — Saltwater reports the temperature break off Pigeon Point has been the most productive zone, with the Salty Lady under Captain Jared Davis working those waters successfully. Look for edges where cooler upwelled water meets warmer surface water; these boundaries concentrate anchovies and sardines, and in turn Chinook. Slow-trolling whole or cut anchovies through the break is the proven approach. NOAA buoy 46028 is reading a noticeably warmer 61°F, pointing to a persistent warm pocket further offshore or along the southern coast reach. That contrast should help narrow down the productive temperature break on the water.

For the next two to three days, conditions should hold if the northwest wind stays in place. NOAA buoy 46026 at 53°F reflects the coldest upwelled water pressing in from the north; the sweet spot for Chinook will typically be where this cold mass transitions to the mid-50s, consistent with buoy 46042 at 55°F. Run a sea surface temperature layer on your chart plotter and troll along temperature breaks rather than fixed waypoints.

Rockfish should remain accessible on structure and reefs through the weekend. Halibut opportunities are typical on sandy flats this time of year, particularly on the incoming tide when bait pushes onto shallower edges. Neither species had direct catch reports in current intel; both are based on late-May seasonal patterns for Central Coast waters.

The first-quarter moon means moderate tidal swings rather than the stronger pushes around a full or new moon, generally manageable for offshore work. Salmon feed most aggressively in low-light windows, so plan to be on the water at first light. With Memorial Day weekend bringing heavier boat traffic out of Half Moon Bay and Monterey, launching early improves both access and your shot at the prime morning bite before the fleet spreads out.

Context

The Central Coast Chinook season has been an uncertain proposition in recent years, with closures and restrictions squeezing fishing in Northern and Central California. Western Outdoor News — Saltwater correspondent Allen Bushnell captures the mood directly: "Many of us almost forgot what it is like to have a real salmon season along the Central Coast," he writes in his Monterey dispatch. That framing underscores just how meaningful the current upwelling-driven improvement is for local anglers.

Late May has historically been a strong window for Central Coast salmon when seasonal upwelling kicks in. Water temperatures in the 53 to 58°F range are ideal for Chinook, which trail baitfish that thrive in cold, nutrient-rich upwelled water. The 53 to 55°F readings across our buoy network fit that textbook template closely. Years with persistent northwest winds through May tend to produce the strongest Central Coast salmon seasons, as sustained upwelling keeps cold water in the productive nearshore band.

Recent years brought headwinds: warm water anomalies, drought effects on river returns, and multiple seasons with reduced or closed salmon fisheries pushed expectations down and sent boats further offshore. The current thermal structure represents a return toward more typical late-spring conditions rather than anything anomalous.

No comparative escapement data or state agency reports were available in current intel to quantify how this year's returns stack up against prior years. What is available: two corroborating reports from Western Outdoor News — Saltwater, one from Monterey and one from Half Moon Bay, both noting a meaningful positive shift within the last two weeks. That convergence of on-the-water testimony points toward a late-May window shaping up better than many anglers had reason to expect.
