Mackerel Runs in San Diego: Timing, Locations, and Quick-Strike Techniques
San Diego’s mackerel runs are among the most predictable and explosive fishing events on the California coast. When conditions align—water temperature, baitfish availability, and seasonal migration patterns—the kelp forests and shallow reefs transform into feeding frenzies that reward prepared spearfishers with fast-paced action and full stringers.
The San Diego Mackerel Season
Pacific mackerel (Scomber japonicus) typically peak in San Diego waters from May through October, with the most consistent runs occurring June through August. Water temperature is the primary trigger: mackerel move inshore and feed aggressively when the Pacific reaches 62–68°F.
April often marks the beginning of the season, particularly around La Jolla Shores and Mission Beach, where warmer nearshore water attracts early arrivals. By July and August, the runs intensify as larger schools establish feeding patterns along the county’s entire kelp belt. September and October remain productive but less predictable as schools begin their offshore migration.
Winter (November–April) is generally a dead zone for mackerel spearfishing in San Diego. Water temperatures drop, and fish move to deeper, offshore structure that’s inaccessible to most shore and boat-based spearfishers.
Prime Mackerel Locations
La Jolla Cove & Point
The cove itself is off-limits to spearfishing, but Point La Jolla’s outer reefs—just north of the reserve boundary—consistently hold mackerel during peak season. The rocky structure and kelp create ideal hunting grounds. Expect 30–50-foot visibility during summer runs, and fish typically feed in 15–35 feet of water.
Torrey Pines Kelp Forest
South of La Jolla, the Torrey Pines kelp is a reliable mackerel destination, especially on morning dives (6–9 AM) before boat traffic intensifies. The dense kelp creates ambush opportunities, and the shallow relief (20–40 feet) makes this accessible even in moderate swell.
Pacific Beach Point
PB Point offers exposed reef structure that attracts roaming mackerel schools. The area is best dived on calm, clear days when swells are under 3 feet. Visibility can exceed 40 feet in summer, and mackerel hunt along the rocky shelves at 25–45 feet.
Ocean Beach Kelp
The extensive kelp forest off Ocean Beach holds mackerel throughout the season, but the area is crowded and has heavy boat traffic. If you dive here, go early and stay deep (40+ feet) to avoid conflict with recreational divers and snorkelers.
Coronado Islands & Kelp
North Island and Middle Island at the Coronado Islands are premium mackerel destinations, though they require a boat. The kelp and rocky structure host schools of quality fish, and the area sees less pressure than mainland breaks. Visibility often exceeds 50 feet.
Quick-Strike Spearfishing Techniques
Read the School’s Movement
Mackerel rarely hold still. They hunt in loose, fast-moving schools that patrol kelp edges and reef structure. Position yourself upwind or upcurrent of where you expect the school to pass. Mackerel have excellent eyesight but poor upwind detection. Wait in ambush rather than chasing.
Use the Kelp
Dense kelp at Torrey Pines and PB Point is your ally. Mackerel hunt along kelp edges where baitfish shelter. Hide in heavier kelp and watch the edges. When a school appears, move deliberately toward the edge without sudden movements. Your first shot opportunity often comes within seconds.
Timing Your Shot
Mackerel are fast and unpredictable once they’re aware of you. Aim for the lead fish in a school—it’s often the largest and most committed to feeding. Use a 5–6mm gun with a sharp, barbed point. Headshots are difficult at speed; aim for the lateral line or gill plate for reliable penetration. At 20–30 feet, you’ll have less than 2 seconds after the school spots you.
Dive During Peak Feed Times
Early mornings (sunrise to 9 AM) and late afternoons (4 PM onward) are when mackerel feed most aggressively. Midday dives, especially in July and August, can be slow. Overcast days often produce better results than bright, sunny conditions.
Work the Thermocline
In summer, a thermocline often forms at 35–45 feet. Mackerel frequently hunt just above this boundary where baitfish congregate. If shallow kelp is slow, drop deeper and look for the thermal transition.
Gear Essentials
A 5–6mm gun with 18–20 feet of float line and a large float is standard. Mackerel runs are short and violent—adequate float gear prevents line tangles and fish loss. Use a quality power head or shaft tip for reliable penetration. A 7mm wetsuit and hood are mandatory year-round in San Diego; water temperatures can cool quickly, especially on morning dives.
Final Notes
Mackerel runs demand patience, positioning, and quick reflexes. Success comes from understanding seasonal timing, scouting locations beforehand, and executing clean shots. The payoff—fast action, quality fish, and consistent results—makes San Diego’s mackerel season essential for serious spearfishers.
