Bluefin in 1-Day Range as Warm Water Jumpstarts the SoCal Season

What's Biting

What's Next

The combination of above-normal sea surface temperatures and early pelagic arrivals sets up one of the more promising early-season offshore windows in recent years. Per Western Outdoor News — Saltwater, bluefin, yellowfin, and at least one albacore are already reachable on 1-day trips from San Diego-area landings, with 2- and 3-day runs extending south turning up denser concentrations, yellowtail, and early dorado. If surface temps hold in the 61–63°F range noted at our buoys — or tick warmer with any southerly influence over the next few days — the yellowtail bite around the Channel Islands should continue to build. This is a development that typically arrives in mid-to-late May but appears to be running ahead of schedule this season.

For offshore targeting, live sardine fly-lined or slow-trolled remains the go-to approach once marks appear, with yo-yo irons productive for bluefin and yellowfin when fish are seen foaming or tracking baits. Yellowtail on island kelp beds respond well to surface irons and live bait pitched to boiling fish or worked tight to structure. The early dorado mixing in on southern runs suggests warm-water eddies are already forming — worth watching for color changes and floating debris lines if running south.

Inshore and surf conditions look favorable across the week ahead. The 3-foot swell at buoy 46221 is workable for most setups, and any further easing toward the weekend would improve access to sandy-bottom surf zones. Surf Fishing in So Cal identifies corbina as the signature spring surf target — best approached with a small sand crab or ghost shrimp on a minimal-weight Carolina-style rig fished in the wave wash during early morning or evening hours. Leopard shark activity also builds through May along sandy-bottomed flats; the waning crescent moon produces darker overnight windows this week, which typically pushes sharks shallower and more active. Per Surf Fishing in So Cal's shark-targeting breakdown, squid or mackerel on a heavier leader soaked near deeper sand troughs after last light is a proven setup.

White seabass are not specifically reported in the current intel cycle but typically stage near Channel Islands and Catalina kelp beds through late spring — check landing counts before making the run. Separately, Western Outdoor News — Saltwater flagged a California Fish and Game Commission public comment session focused on potential MPA expansion set for San Clemente on May 19. Confirm your target grounds remain open under current regulations before heading out.

Context

For most years, early May in the LA Bight and Channel Islands sits in the transition between late-winter rockfish patterns and the summer pelagic run. Sea surface temperatures typically hover in the mid-to-upper 50s°F through April — historically the coldest ocean month along this coast — before climbing toward the low 60s°F by mid-June. This spring has broken sharply from that template.

Western Outdoor News — Saltwater correspondent Merit McCrea reported from San Clemente in late April that offshore temperatures had pushed into "the very high 60s," representing a departure he describes as exceeding 10 degrees above normal — a swing that dwarfs even the peak of the 1983 El Niño event. Whether a formal El Niño or a separate warm-water pattern, the biological response is unmistakable: bluefin and yellowfin in 1-day range, the first San Diego fleet albacore in years gaff'd April 30, and dorado already appearing on southern runs. These are pelagic arrivals that typically don't materialize until June or later in most years.

Warm early seasons off Southern California — particularly El Niño years — have historically correlated with strong summer yellowtail runs around the Channel Islands, closer-to-shore tuna, and occasionally wahoo working farther north than usual. Anglers who fished the 2015–16 warm-water event will recognize the setup: species showing up weeks ahead of schedule, bait concentrations pulling pelagics that normally require a longer run. Our buoy readings of 61–63°F confirm that inshore water is also above typical early-May levels, even if not yet at the offshore anomaly peak noted by WON.

Surf species — corbina and leopard shark — appear to be arriving on a fairly normal spring schedule per Surf Fishing in So Cal's April season preview, suggesting the warm-water anomaly is primarily an offshore phenomenon so far. No state agency reporting is available in the current intel cycle for a more granular comparison.
