Central Coast Chinook salmon bite improving as upwelling and cool temps align
Water temperatures off Monterey have pulled down to 54°F (NOAA buoy 46042), and that cold-water shift is already paying off for Central Coast salmon anglers. Captain Jared Davis of the Salty Lady, working out of Half Moon Bay Sport Fishing, reported that temps fell from 58°F to 54°F below Pigeon Point — and per Western Outdoor News — Saltwater, the bonita cleared out with that temperature drop while salmon conditions reached their best point of the season. A separate Monterey-dateline report in Western Outdoor News — Saltwater echoes this, noting that an increase in northwest winds has triggered productive upwelling along the Central Coast, drawing cold, nutrient-rich water to the surface — the exact setup Chinook need to stage and feed. Buoy 46028 at Cape San Martin reads warmer at 60°F with waves near 5.6 feet, suggesting a thermal gradient worth exploring between those stations. Rockfish and halibut remain seasonally present but drew no direct field reports this cycle.

What's Next
The upwelling engine driving these conditions shows no signs of stalling. Northwest winds registered at 3–5 m/s on buoys 46028 and 46026 overnight, and as long as that pattern holds, cold upwelled water will continue to funnel toward the surface and push baitfish — and the Chinook that follow them — into reachable depths. Western Outdoor News — Saltwater's Monterey report described this as a turning point in a season that was slow to develop, and the current thermal profile bears that out: the four-to-five-degree temperature drop documented in recent weeks is precisely the trigger that pulls salmon into a productive feeding posture along this stretch of coast.
Waves running 4.9 to 5.6 feet at offshore stations (buoys 46042 and 46028) mean conditions will suit boats that can handle a moderate swell. The lighter 3.9-foot reading at buoy 46026 suggests some relief closer to shore or in the lee of headlands. Plan departure times around early-morning windows when northwest winds typically lay down before rebuilding mid-day — that window often delivers the most comfortable run and the best surface bite.
The First Quarter moon puts us in an intermediate tidal range, neither the strong spring pull of a full or new moon nor the slackest neap water. For salmon, that can actually work in anglers' favor: moderate current keeps baitfish moving without creating the chaotic churn that scatters a bite. Target early-morning and late-afternoon tide transitions when anchovies and sardines tend to school tight and stay in the strike zone.
If the upwelling holds through the weekend, look for rockfish to stack along the same cold-water breaks that are holding Chinook. Nearshore structure along the Central Coast — kelp edges, rocky reefs, submarine canyon rims — comes alive when nutrient-rich upwelled water pushes krill and baitfish toward the surface. Halibut should be findable on sandy bottom adjacent to those structures, though no direct field reports put them in the spotlight this week.
Watch the northwest wind forecast closely over the next two to three days. A sustained blow deepens and widens the upwelling zone; a flat calm allows surface temperatures to rebound and can push the salmon bite offshore or deeper. Check NOAA marine forecasts before departure — conditions can shift significantly between a 15-knot and 25-knot northwest wind, both in sea state and in where the fish are holding.
Context
The Central Coast typically enters its Chinook salmon season in earnest as spring upwelling intensifies through April and May. In a normal year, northwest winds and California Current dynamics push cold, baitfish-rich water close enough to shore that anglers can reach productive salmon grounds within a reasonable run from Monterey Bay ports.
What makes this moment stand out, per Western Outdoor News — Saltwater, is the contrast with recent lean years. The outlet's Monterey correspondent noted that "many of us almost forgot what it is like to have a real salmon season along the Central Coast of California," framing the current conditions as a genuine departure from a difficult stretch. Chinook populations on the Pacific Coast have faced compounding pressure from warm-water anomalies, reduced snowpack affecting river spawning habitat, and shortened or closed seasons in some recent years — making this spring's upwelling-driven improvement particularly welcome for anglers who have been waiting it out.
At 54°F off Monterey (NOAA buoy 46042), the water sits squarely in the productive salmon temperature range for late May. Historically, the low-to-mid 50s on the Central Coast concentrate Chinook and keep anchovies and sardines at fishable depths. The 60°F reading at Cape San Martin (NOAA buoy 46028) is on the warmer edge for this stretch but likely reflects that station's position south of the main upwelling plume rather than a system-wide warming trend.
On balance, the current setup — cool inshore temperatures, active upwelling, northwest winds pushing bait toward the surface — is ahead of where the Central Coast fishery has been in several recent springs. If the upwelling pattern persists into early June, this could shape up as one of the more productive late-May Chinook windows the region has seen in a while.
