Warm Water Pulls Tuna and Yellowtail Into SoCal Range Well Ahead of Schedule

What's Biting

What's Next

Over the next two to three days, conditions look favorable for both offshore and inshore pursuit. NOAA buoy 46221 is registering 4.6-foot swells — manageable for most sportboats but worth checking before running to the islands. Winds at NOAA buoy 46025 are light, around 4 meters per second (roughly 8 knots), suggesting calm morning windows before typical afternoon sea breezes build.

The offshore opportunity is the headline. Western Outdoor News — Saltwater reports that the warm-water push has put bluefin and yellowfin tuna within one-day range of SoCal-area ports, with yellowtail active on multi-day trips pushing south and some early dorado mixed in. The warm band of water confirmed by our buoy readings is likely to hold or strengthen through late May. If the thermal edge pushes northward, the northern Channel Islands and Catalina could come into play for day-trip yellowtail and potentially bluefin within the next week or two. Anglers running to the islands should be scouting kelp paddy lines and surface temperature breaks — this is exactly the type of early-season warm-water year where an opportunistic mid-May trip can deliver something unexpected.

The New Moon creates some of the month's strongest tidal exchanges, and that movement matters inshore. Surf anglers targeting corbina and leopard sharks should time outings to the first two hours of an incoming tide, particularly in the early morning hours. Surf Fishing in So Cal highlights sandy beach breaks as the prime zone for both species — corbina work the wash as sand crabs tumble in the swash, while leopard sharks cruise the shallows for squid and small fish on the push.

Looking a few days farther out: if swell drops below three feet and light winds persist, calico bass and sheephead on kelp-edge structure inside the Channel Islands become productive secondary targets while the offshore tuna bite consolidates farther out. Water at 62–64°F sits squarely in the comfort zone for those species in shallower structure.

Dorado remain a longer shot for the LA Bight proper at mid-May, but the pace of this warm-water season has surprised nearly everyone. Anglers running offshore should keep a high-speed trolling lure in the spread when crossing blue-water edges — where there is warm water and flying fish, dorado tend to follow. The window is open; move on it.

Context

A typical mid-May in the LA Bight finds surface temperatures in the upper 50s to low 60s Fahrenheit, with winter upwelling giving way to slow seasonal warming. In an average year, offshore anglers still have weeks to wait before tuna reach practical range, and the corbina and leopard shark surf season is just barely flickering on as water edges toward 60°F.

This year is tracking meaningfully ahead of that curve. Western Outdoor News — Saltwater devoted a detailed feature to the anomaly under the headline "Hot Water! Is it El Niño?" — noting that April waters off Southern California were running 10 or more degrees above normal for the season, with temperatures reaching the very high 60s. The piece, filed from San Clemente, frames the departure as extraordinary even by El Niño standards, noting that the biggest positive anomaly recorded in the 1983 event was roughly 7 degrees above normal and that what's been observed this spring exceeds that benchmark. By mid-May, buoy readings have moderated to 62–64°F, but those numbers still represent significantly above-normal conditions for this date.

The practical consequence: species that typically don't appear in practical range until June or July are here now. The first San Diego fleet albacore in years, caught April 30, is the kind of early-season milestone that anglers remember for decades, per Western Outdoor News — Saltwater. Yellowtail inside one-day range in May is also ahead of the typical calendar.

For the surf angler, above-normal water temperatures this early tend to compress and accelerate the corbina and leopard shark windows — both species become active earlier when the water heats ahead of schedule. Surf Fishing in So Cal covers both extensively as core SoCal warm-water targets, and the current temperature setup should support a longer and more productive active window than most years provide.

The caveat worth noting honestly: California warm-water anomalies can collapse quickly when an upwelling pulse pushes cold sub-thermocline water up the shelf. Anglers should monitor sea-surface temperature charts alongside buoy readings rather than assuming the warmth holds — and move on offshore windows when the conditions align rather than waiting for a more convenient weekend.
