As expected in early January, water temperatures have dropped into the mid to high 50s, prompting both boat captains and anglers to adjust their strategies and target species that are more active in cooler waters. During this time of year, common target species include sculpin, ocean whitefish, sand dabs, and halibut. While sand bass and calico bass remain viable options, their availability varies depending on specific locations along the Southern California coast.
One of the primary catches for the sportfishing fleet during the cooler months is the California scorpionfish, commonly known as sculpin. These prized fish are often found in large numbers over deep, hard-bottom areas, making them a staple for both charter boats and private anglers. Anchoring over these hard-bottom zones allows anglers to target sculpin effectively. The recommended setup involves a rubber lure rigged on a heavy sinker using a dropper loop configuration, which ensures the bait reaches the bottom quickly where sculpin are actively feeding. As of 2025, the possession limit for sculpin is five fish per angler, with a new regulation eliminating the minimum size requirement. Although size limits are no longer enforced, anglers are encouraged to practice conservation by harvesting only larger specimens.
Ocean whitefish, another key species during this season, are frequently caught alongside sculpin in hard-bottom areas. Due to their smaller mouths, downsizing to a No. 2 or No. 4 hook can improve catch rates. Strips of squid are highly effective bait for whitefish, although occasional bycatch of rockfish can occur. Since rockfish must be released, charter captains make a concerted effort to avoid areas where rockfish are prevalent while focusing on zones rich in whitefish.
In recent years, targeting sand dabs has become an increasingly popular alternative during the cooler months. These flatfish thrive in open, muddy-bottom areas at depths of 200 to 300 feet. Using pre-made rigs with 5 to 10 hooks provides a fun and efficient way to catch these tasty fish. With no size or possession limits, sand dabs offer a great opportunity for anglers looking to fill their coolers and enjoy delicious table fare.
Halibut also remain a sought-after species in cooler waters. Drifting over open areas near the edges of hard-bottom reefs and muddy bottoms can yield productive results. Key factors in targeting halibut include locating large baitfish schools, such as sardines, anchovies, and squid, as well as drifting bait along the bottom beneath these schools. Live mackerel or sardines make excellent bait, and using appropriately sized hooks is crucial when fishing with large live bait. Since halibut can be challenging to target, anglers should remain mobile, searching for favorable conditions such as current and water movement.
While bass fishing is traditionally associated with summer, winter bass fishing remains possible with some adjustments. Cooler water slows down the metabolism of sand bass and calico bass, making them less likely to strike bait compared to warmer months. However, fishing over deep structures in the 60- to 100-foot range can still yield results. Live bait presented on dropper loops or sliding sinker setups tends to be effective. Some anglers opt for artificial lures, using heavier lead-head jigs and swimbaits to entice bites from both sand and calico bass. Tube jigs have also gained popularity as an effective lure. Observing the location of lobster traps, often set near hard-bottom or rocky areas, can help identify productive spots for winter bass fishing.
Despite the cooler water temperatures, fishing during the winter months can still be highly rewarding. With a few tactical adjustments, anglers can enjoy a fun and productive trip even in these challenging conditions.
