Bluefin tuna charge into range early as SoCal waters run hot

What's Biting

What's Next

With water temperatures running 5–10°F above historical averages for mid-May — a pattern Western Outdoor News — Saltwater suggests may reflect El Niño-driven warming — the near-term outlook favors continued offshore pelagic action as long as no strong upwelling event disrupts the warm surface layer.

**Pelagic fishing**: Bluefin and yellowfin tuna are the headline act right now, with Western Outdoor News — Saltwater confirming fish within 1-day range southwest of San Diego. That puts the grounds accessible to LA- and OC-based boats willing to make the run south. If the warm water holds through the weekend — and current buoy readings show no cooling signal — the bite should remain on. Early morning trolling or topwater during the first hour of light is the traditional go-to when fish are this active near the surface. Two- and three-day boats are already reaching yellowtail and scattered dorado farther south, per Western Outdoor News — Saltwater.

**Albacore watch**: The single albacore gaff'd April 30 aboard the Tribute out of Mission Bay (per Western Outdoor News — Saltwater) is a lone data point — don't plan a trip around one fish — but it signals the water is warm enough to pull them in. Watch fleet reports closely over the coming week; if offshore temps continue to climb, a broader albacore show becomes plausible.

**Surf and inshore timing**: Buoy 46221 reads 65°F in Santa Monica Bay, which is squarely in the window where corbina activity picks up. Surf Fishing in So Cal's April season preview indicates the surf season is gaining real momentum. With tonight's Last Quarter moon producing moderate tidal movement, the best surf windows will be the two hours on either side of the incoming tide — typically late afternoon into dusk — when corbina push into the wash to feed on sand crabs. Leopard sharks follow the same tidal rhythm and are an excellent shore target throughout this temperature range.

**Access note**: Western Outdoor News — Saltwater flags a California Fish and Game Commission meeting scheduled for May 19 in San Clemente on potential MPA expansion along the Southern California coast — anglers who fish the Bight and Channel Islands should be aware that access boundaries may be under active review. Check current state regulations before targeting rockfish or bottomfish, as California's 2026 rules include multiple zones and seasonal windows.

Context

For the Southern California Bight in mid-May, water temperatures of 62–65°F represent a meaningful departure from historical norms. Offshore SoCal temps in May typically average closer to 56–60°F, with the warmest inshore readings usually arriving in the low 60s by late May at the earliest. Western Outdoor News — Saltwater put it plainly: April and early May 2026 have seen departures of 10°F or more above normal — comparable in magnitude, WON notes, to conditions not seen since the 1983 El Niño, when the single biggest departure on record was around 7°F above normal. By that benchmark, this year's anomaly is even more extreme.

The practical fishing consequence is a season running several weeks ahead of schedule. Bluefin tuna arriving within 1-day range in early May is typically a June-or-later phenomenon in most years. Albacore appearing off San Diego in late April is even more unusual — Western Outdoor News — Saltwater describes the April 30 gaff as "the first San Diego fleet albacore in years," underscoring just how out-of-season the fish felt to local skippers accustomed to a late-summer albacore calendar.

Surf species are closer to their normal timing. Corbina in Southern California typically peak May through September as sand crab populations build along sandy beaches, so their imminent arrival on area shorelines — flagged in Surf Fishing in So Cal's April season preview — tracks with normal patterns, though above-normal water temps may pull them in a couple of weeks earlier than usual. Leopard shark fishing is similarly a spring-through-fall pattern that aligns naturally with current conditions.

The key uncertainty is persistence. Strong coastal upwelling events can crash surface temps by 5–8°F in under 48 hours, pushing pelagics back out of 1-day range without warning. If El Niño-driven warmth holds through summer, SoCal could be positioned for a banner offshore season; if upwelling reasserts, the early tuna and albacore window may be brief. Either way, conditions right now are as favorable as many local anglers have seen in a decade, and the bite is happening ahead of the crowds.
