Long Beach Offshore Fishing

Long Beach sits at the northern edge of the San Pedro Channel, with Catalina Island just 26 miles to the southwest — making it one of the most accessible offshore fishing ports in Southern California. The Long Beach and San Pedro sportfishing fleet is one of the largest on the West Coast, running everything from half-day local trips to multi-day offshore runs. Catalina Island provides a protected fishery with kelp forests, rocky structure, and blue-water access on the backside. The Horseshoe Kelp, an artificial reef complex closer to shore, offers local fishing year-round. Beyond Catalina, the deep-water grounds of the outer Bight — including the 14 Mile Bank to the southeast and the 277 Spot — come into play when warm-water conditions develop.

The Long Beach fishing calendar revolves around seasonal warm-water arrivals. Barracuda and bonito are among the first arrivals, pushing into the area from March through May. Yellowtail show up by April, with peak fishing from May through July around Catalina Island and the kelp edges. Bluefin tuna have become a major fishery in the outer Bight from January through July, with fish from 20 to over 200 pounds feeding on the banks and ridges offshore. Yellowfin tuna arrive in summer when water temperatures reach 68 degrees, typically from July through October. White seabass provide a prized spring target along the kelp line, with peak action from March through June. Calico bass are a year-round staple around Catalina's kelp forests and rocky structure, keeping anglers busy when pelagic conditions are slow.

Long Beach anglers need to monitor two distinct zones: the inner channel between the mainland and Catalina, and the outer Bight beyond the island. In the channel, SST charts reveal how warm water is moving through the San Pedro Channel — when temperatures at Catalina's backside reach 65 degrees, yellowtail and bonito fishing improves noticeably. For the outer grounds, track the warm-water boundary south and west of Catalina. When 68-degree water pushes to the 14 Mile Bank, yellowfin tuna become a realistic target. For bluefin, which tolerate cooler water, look for bait concentrations along temperature gradients on the outer banks. Kelp paddies drifting in warm water south of Catalina are worth investigating for dorado and yellowtail. Current flow through the channel, which Rigline tracks, affects bait movement and fish positioning around the island.

Rigline helps Long Beach captains navigate the diverse options in the Southern California Bight. Our SST analytics show water temperature at Catalina, across the outer banks, and along the warm-water edge, helping you decide between a local island trip and a longer offshore run. Trend data reveals whether warm water is advancing or retreating through the Bight, which directly affects species availability. For the bluefin tuna fishery on the outer banks, Rigline's precision SST data identifies exactly where fish are staging relative to bait and structure.
