Yellowfin and Dorado Stack Up on SoCal Kelp Paddies as Surf Finally Settles
Warm water is pulling yellowfin tuna, dorado, and yellowtail into range along the Orange County coast, with Dana Wharf Sportfishing's Sum Fun landing 43 yellowfin in the 30- to 40-pound class for 26 anglers off San Clemente Island, captain Brian Woolley reported via Western Outdoor News — Saltwater. Sea surface temps hit 80°F near San Clemente and held in the upper 70s from Oceanside to Newport, with boats picking dorado and yellowtail off kelp paddies as far north as Santa Cruz Island. Our nearshore buoy reading came in a touch cooler at 76°F. Sand bass are drawing attention too — the Pfleger Institute for Ecological Research has tagged over 1,000 fish at and below the border this season, per Western Outdoor News. Surf anglers, meanwhile, are finally catching a break: after a brutal, rough-surf stretch through July, Surf Fishing in So Cal calls August "the best opportunity we've had all year."

What's next
Water temperatures in the mid-to-upper 70s — and reportedly touching 80°F near San Clemente Island per Western Outdoor News — Saltwater — suggest the warm-water pulse pushing yellowfin, dorado, and yellowtail into local range should hold over the next few days if the mild wind pattern at buoy 46025 (around 4 m/s) persists. Light wind typically keeps kelp paddies intact and drift conditions fishable, both of which matter for the live-bait tuna bite Dana Wharf described off San Clemente.
If the pattern holds, expect the yellowfin and dorado bite to keep pushing along the kelp lines toward the Channel Islands and beyond — Western Outdoor News already noted boats finding fish as far north as Santa Cruz Island. Anglers working local waters should watch for kelp paddies holding bait; that's typically where the school-sized yellowfin and dorado are stacking up right now.
The sand bass fishery is worth watching as well. With PIER's tagging program past 1,000 fish tagged at and below the border this season, that's a signal of solid sand bass presence in the region — SoCal has historically seen strong sand bass bites develop through late summer when numbers run this heavy, though that isn't guaranteed to repeat this year.
For surf anglers, the picture is cautiously optimistic. Surf Fishing in So Cal reports August has finally delivered a break after what the site calls the most consistently elevated surf in over a decade, tied to this year's El Niño pattern. If that settling trend continues into the weekend, surf conditions should keep improving — but check local surf forecasts before heading out, since swell can turn quickly this time of year.
The Full Moon this week typically means stronger tidal swings and current, which can concentrate bait and gamefish around structure and kelp — worth factoring into timing for both boat and shore trips over the next few days. With buoy 46221 showing a moderate 3.9 ft swell, conditions look fishable but not glassy; plan accordingly for boat comfort and safety.
Context
Late August is peak warm-water season for the Southern California Bight, and this year's pattern reads as on-schedule to slightly ahead for the offshore tuna and dorado bite — sea surface temps in the upper 70s to 80°F near San Clemente Island are typical of a strong late-summer warm-water push, and Western Outdoor News — Saltwater's report of a 43-fish yellowfin day for Dana Wharf's Sum Fun is consistent with a healthy August kelp-paddy season rather than an outlier.
The surf fishery tells a different story. Surf Fishing in So Cal describes 2026 as an outlier year on the negative side, pointing to a sustained rough-surf stretch tied to El Niño that ran from roughly May through July — by the site's account, the most consistently elevated surf conditions in over a decade of fishing the San Diego coast. That the same source is calling August "the best opportunity we've had all year" suggests the surf fishery is only now recovering toward something closer to a normal seasonal pattern, running behind where a typical year would sit by late summer.
The sand bass tagging effort from PIER, now past 1,000 fish tagged at and below the border this season, doesn't give a direct year-over-year comparison on its own, but the scale reflects sustained interest in the summer sand bass schools that periodically show up in bigger-than-expected numbers in SoCal waters.
Overall: offshore pelagics look to be running a normal-to-strong late-summer program, while the surf fishery is playing catch-up from an unusually disrupted spring and early summer.
