Cooler upwelling fires up Chinook salmon below Pigeon Point

What's Biting

What's Next

The cooling trend below Pigeon Point is the dominant story heading into mid-May. Northwest winds at buoys 46042 and 46028 are holding at 8–10 m/s — levels consistent with active upwelling that draws cold water up along the Central Coast shelf. As long as this pattern persists, Chinook salmon should remain in productive range below Pigeon Point. Per Western Outdoor News — Saltwater, the current 54°F window is where the action is; significant re-warming would need to happen before bonito reclaim the grounds.

The waning crescent moon is shrinking toward a new moon around May 19. Darker nights suppress surface baitfish activity overnight, concentrating anchovies and sardines tighter to structure by first light. The pre-dawn window — roughly 30 minutes before sunrise to an hour after — is worth prioritizing for salmon trollers working flasher-and-hoochie rigs or sardine-wrapped lures along the 60–180 foot depth contours.

Rockfish and lingcod should remain reliably active on offshore pinnacles and kelp-edge structure through the week. Cooler bottom temps keep these species tight to cover. Pacific halibut haven't featured in this week's reports, but mid-to-late May is historically when flatties begin moving onto sandy nearshore flats across the region — worth a prospecting drift if rockfish limits fill early.

Pacific bonito retreated with the cooling water, per Captain Davis's account. A return to 58°F-plus surface temps would be required to draw them back inshore. Early bluefin and yellowfin activity was reported by Western Outdoor News — Saltwater well south off San Diego, but those fish have not yet reached Central Coast range as of mid-May.

Weekend anglers planning May 16–17 trips should note that northwest winds along the Central Coast commonly ease Saturday morning before rebuilding Sunday afternoon. An early Saturday launch will typically be the safer bet. Always confirm bar and offshore conditions with local landings before departure when winds are running above 8 m/s.

Context

Mid-May is traditionally prime time for Chinook salmon along the California Central Coast. The spring salmon season typically opens in early-to-mid April out of Half Moon Bay, and the first weeks often feature warmer surface water — exactly what Captain Davis described at season's opening, with 58°F readings on April 11. The subsequent drop to 54°F by mid-May aligns with the classic upwelling cycle: as northwest winds strengthen in late spring, cold water wells up from depth along the shelf, suppressing warm-water species like bonito while concentrating the baitfish schools that attract Chinook.

Western Outdoor News — Saltwater separately noted that California coastal waters were running unusually warm earlier this spring, with surface temperatures approaching the high 60s in some offshore areas — roughly 10°F above historical April norms, fueling El Niño speculation. The Pigeon Point area sitting at 54°F despite that backdrop suggests localized upwelling is keeping a productive cold-water corridor intact for the Central Coast salmon fishery, even as broader warm anomalies persist offshore.

No direct year-over-year comparisons were available in this week's intel feeds. That said, a 54°F mid-May reading near Pigeon Point is on the cooler end of recent warm-year ranges, which historically correlates with better Chinook concentration and bite quality. The season is young enough that a sustained cold-water window through the end of May could set up an above-average run for the Central Coast fleet. Regulatory note: the salmon fishery operates under annual state season announcements and can include area-specific closures — verify current openings and bag limits before launching.
