Seasonal Guide to Target Fish in Harbor Island

Harbor Island, San Diego, is home to an incredible variety of inshore and offshore fish species, offering anglers world-class fishing opportunities throughout the year. Whether you're chasing trophy Bluefin Tuna, Yellowtail Amberjack, or Mahi Mahi, each season brings its own set of exciting fishing conditions.

Spring and summer are prime times for offshore fishing, as warmer waters attract migratory species like Yellowfin Tuna, Dorado (Mahi Mahi), and Wahoo. These months also bring excellent opportunities for surface action with topwater lures and live bait. In the fall, the tuna bite remains strong, while Rockfish, Halibut, and Lingcod dominate the bottom fishing scene. Winter offers some of the best inshore fishing, with Calico Bass, Sheephead, and Halibut providing steady action along the coastal reefs and kelp beds.

These species are typically found in deeper waters, requiring techniques like trolling, kite fishing, and drifting with live bait.
