Fall Lobster and Spearfishing Season Overlap: San Diego’s Golden Window
Every October, San Diego spearfishers know what’s coming: the convergence of peak lobster season, cooling water temps, and improved visibility that makes fall the year’s most productive hunting window. If you’re not in the water during this overlap, you’re leaving serious protein on the table.
When the Window Opens
California’s recreational lobster season runs October 1 through mid-March, but the real gold is September through November. Water temperatures drop from summer’s 72°F to the mid-60s by November, which triggers lobster movement and makes them more active in shallower waters. For spearfishers, this means the shallow reefs and rocky points that were dormant in summer suddenly hold both lobster and quality fish.
The timing is deliberate: September storms clear the water, September swells push baitfish into deeper zones, and by early October the ocean has settled into that sweet spot—manageable conditions, clear visibility, and motivated prey.
Where to Focus: San Diego’s Prime Lobster Zones
La Jolla Reefs and the Gully The Gully and surrounding reefs off La Jolla Shores are textbook lobster habitat. Rocky outcrops and kelp edges hold resident lobsters year-round, but fall brings migration from deeper water. Visibility here typically runs 25–40 feet in October, and the shallow rocky terrain (15–35 feet) is ideal for breath-hold hunting. Hunt the edges of the reef where rock meets sand—lobsters stage there before moving in.
The Wreck and Kelp Zone (Bird Rock) Off Ocean Beach, the deeper wreck and surrounding kelp beds attract spearfish and lobster alike. October swells can make access tricky, but on calm days the 40–60 foot zone here holds quality calicos, sheephead, and legal-sized lobster. The kelp forest provides cover, which means lobsters are more confident and less skittish.
Torrey Pines Artificial Reef Calico bass and lobster congregate around the pilings and structure. Fall conditions here are typically mild, and the 45–55 foot zone is accessible for most divers. Lobster density here rivals natural reefs, and the bonus is the variety of spearfish—sculpin, sheephead, and smaller calicos in the structure.
Point Loma and Sunset Cliffs The rocky points and kelp forests off Point Loma are less crowded than La Jolla but equally productive. Fall swells can make entry and exit challenging, but the payoff is consistent lobster and fewer hunters. The 30–50 foot zone is optimal.
Conditions to Watch
Water Temperature and Visibility Track Element’s real-time conditions. When water temps hit 66–68°F and visibility exceeds 30 feet, you’re in the window. October typically delivers this 3–4 times per week; November sustains it more consistently. Avoid hunting the day after heavy rain—runoff clouds the water for 24–48 hours.
Swell and Current Fall swells are common, but they clear the water. Hunt the day after a swell when visibility peaks but the water is still energized. Morning dives are safer—afternoon swells build, and currents intensify. Check Element’s swell forecast before committing.
Moon Phase Lobster are more active during darker nights. Hunt the new moon and waning moon phases when lobster forage more aggressively. Full moons see lobster tucked deeper in holes, making them harder to extract.
Technique: Lobster-Specific Approach
Fall lobster hunting differs from summer. Lobsters are more confident and less tentative. Use a long, sturdy pole spear (not a gun) to maintain control when extracting from rocks. Approach slowly and deliberately—sudden movement triggers retreat into inaccessible crevices.
Look for antennae extending from holes and rocks. Work the reef methodically, checking every shadow. Bring a good light and a mesh bag that keeps lobster secure without tangling. Gloves protect against urchins and sharp rock.
Pair lobster hunting with opportunity spearfishing. If calicos, sheephead, or scorpion fish appear, you’re armed to take them. This dual approach maximizes every dive.
Legal Notes
Ensure your lobster are minimum legal size (3.25 inches carapace length). Bag limit is six per day. Spearfishing regulations vary by zone—check CDFW regs for your specific break. No lobster traps for recreational hunters; pole spear, hand, or net only.
The Bottom Line
October and November represent San Diego’s spearfishing sweet spot. Conditions align, prey is motivated, and lobster are accessible. Plan your dives around Element’s forecast, hunt the reefs you know, and commit to consistent early-morning sessions. The overlap doesn’t last forever.
Use Element to track real-time water temps, visibility, and swell forecasts—then get in the water while the window’s open.
