Tuna Creep Into 1-Day Range as Warm SoCal Waters Come Alive for May

What's Biting

What's Next

With today's new moon, tidal swings over the next 48–72 hours will be among the strongest of the month. For surf anglers, that translates to productive feeding windows at the trailing edge of low tide and during the first hour of the incoming push — the moment baitfish and invertebrates flush across the sand flats and predators key in. New moon tides are historically among the more consistent producers for corbina and leopard shark in the surf zone, and with water already at 65°F, both species should be dialed in through the weekend.

Offshore, the warm-water window looks to have more room to run. NOAA buoy 46025 is reading light winds alongside 5.2 ft swell — manageable for most sportfishing vessels heading to the Channel Islands or the bluefin grounds. The slightly calmer swell at buoy 46221 (4.3 ft) suggests better conditions closer to the inner Islands. If the typical late-May afternoon seabreeze sets up, lee-side anchorages on east-facing Island passages will be key; plan to be on structure before 10 a.m. to work the cleaner morning window.

Western Outdoor News describes the current bluefin and yellowfin spread as "extensive," with fish spread across a wide zone that makes both 1-day and 2–3-day trip options viable. If the warm eddy nudging surface temps above seasonal norms continues its northward push toward the Channel Islands, yellowtail activity around island kelp and offshore structure could escalate noticeably heading into the weekend. Live bait and iron are the standard plays once fish are located.

For the beach, early mornings remain the highest-percentage window before wind and swell build. Corbina respond well to sand crabs and ghost shrimp worked through the wash, while leopard shark — per technique guidance from Surf Fishing in So Cal — are best targeted on sandy flats near bay and estuary mouths as water temps hold in this 65°F range. The new moon tidal cycle runs strong Friday through Sunday, making this coming weekend an ideal window to commit a session to either the surf or the offshore grounds.

Context

By mid-May, SoCal surface temps typically run in the 59–62°F range, with bluefin tuna generally a 1.5- to 2-day-trip proposition from most LA Bight and San Diego departures. Albacore rarely show up inside 1-day range before June or July in a normal year, and dorado — when they appear at all — are usually a late-June or July arrival. This season is running meaningfully ahead of that baseline on all three counts.

Western Outdoor News frames the anomaly directly, noting that in April — typically the coldest water month off California — surface temps were pushing into the high 60s in some areas, running more than 10°F above normal. Their coverage floats El Niño and even super El Niño as possible drivers, though the causal picture is still developing. What's clear from the buoy data and fleet reports is that the fish have responded: bluefin and yellowfin on the grounds by early-to-mid May, a first albacore for the San Diego fleet in several years at the end of April, and early dorado already appearing on 2–3-day trips south.

For surf species, Surf Fishing in So Cal acknowledged a "strange start" to the season in their April recap, but their May report strikes a decisively more optimistic tone. Corbina and leopard shark typically peak from late May through August when surf water reliably crosses the 63–65°F threshold. The fact that our buoys are already reading 65°F in the third week of May puts both fisheries a couple of weeks ahead of a typical seasonal schedule — welcome news for surf regulars.

If warm conditions hold, this season has genuine potential to rank among the stronger pelagic years the region has seen in some time. That said, SoCal offshore fishing is famously variable — upwelling events can flip surface temps several degrees in a matter of days, and early-season promise doesn't always carry through the full summer. Monitor sea surface temperature charts closely before committing to multi-day offshore travel.
