Lobster Season Overlaps with Spearfishing: San Diego’s Fall Opportunity
October 1st marks the opening of California’s recreational lobster season—and for San Diego spearfishers, it’s the signal to gear up. The overlap between prime spearfishing conditions and peak lobster availability creates a narrow but valuable window. Here’s what you need to know to make the most of it.
The Timing: Why October Matters
Recreational lobster season runs October 1st through June 15th, but the first three months are the most productive. Water temperatures in San Diego drop into the mid-60s by late September, triggering lobster migration from deeper waters into the shallows. Simultaneously, fall swells subside and visibility improves—conditions that favor spearfishing across the county’s best reefs.
This convergence doesn’t last. By mid-November, water temps stabilize and lobster distribution spreads. Early October is your sweet spot.
Where to Target: San Diego’s Prime Lobster Grounds
La Jolla Shores and the Caves The kelp forests and rocky outcrops around La Jolla Shores and the Caves hold dense lobster populations in fall. Depths of 20–40 feet offer the richest returns. The sandy approaches to the reefs are easy entries; the structure holds both lobster and quality rockfish.
Point Loma’s Kelp and Reefs The kelp forests off Point Loma—particularly around Sunset Cliffs and the Kelp Beds—concentrate lobster in October. Visibility often exceeds 30 feet this time of year. Target the edges of kelp, rocky transitions, and crevices. Boat access to deeper reefs (60–80 feet) yields fewer but larger lobster.
Coronado Islands The reefs around North Island and South Island hold aggressive lobster. These spots require boat access but reward prepared divers with consistent yields and often excellent visibility. Fall swells are manageable here compared to summer.
Torrey Pines and the Gully Shore-accessible spearfishing at Torrey Pines improves dramatically in October. The rocky gully and surrounding reefs see lobster move into 15–35-foot depths. This is a solid alternative when boat access isn’t an option.
Conditions to Watch
Water Clarity October typically delivers 25–40-foot visibility across San Diego’s reefs. This is ideal for both spotting lobster and identifying legal-sized animals before you approach. Poor visibility in early October (common after summer swells) can improve within days—check the Element app for real-time conditions.
Swell and Current Fall swells diminish through October, but north and west-facing breaks can still see 3–5-foot sets. Reefs on the leeward side of points—like the protected waters around La Jolla Cove’s approaches—offer calmer conditions. Currents accelerate as water temps drop; plan dives for slack periods around tide changes.
Water Temperature Mid-60s Fahrenheit in October means a 5mm or 7mm wetsuit is essential. Lobster activity peaks in cooler water, but prolonged exposure degrades your performance. Dress appropriately and limit bottom time.
Rules and Regulations
Know the limits before you go:
- Minimum size: 3.25 inches carapace length (the body, not including antennae)
- Bag limit: 6 lobster per day
- Closed areas: Marine Protected Areas (MPAs) including much of La Jolla and Torrey Pines—know the boundaries
- Licensing: You must have a California fishing license with a lobster report card
San Diego’s MPAs are enforced. Verify access before launching at La Jolla, Torrey Pines, or any protected area. The Element app provides updated boundary maps and seasonal restrictions.
Gear and Technique
Bring a lobster net or bag. Legal-sized lobster are strong; trying to hand-load them into your BC pocket results in lost animals. A small, rigid net works better than a mesh bag in kelp. Gloves protect your hands from sharp rock and spines.
Lobster hide in crevices during daylight. Approach reefs slowly, scan rocky transitions, and probe shallow caves. Early morning dives (first light) often produce better results than midday. Move deliberately; spooking lobster into deep crevices wastes time.
The Spearfishing Bonus
While targeting lobster, you’ll encounter quality rockfish, kelp bass, and calico bass in the same habitat. Bring a speargun and take fish when opportunities arise. October’s cooler water and improved visibility make it one of the year’s best months for all reef hunting.
Getting Started
October’s window is short. Plan your dives now—scout conditions with the Element app, check MPAs, and confirm licensing. Whether you’re shore-diving at Torrey Pines or boat-diving the Coronado Islands, the overlap of lobster season and spearfishing conditions is San Diego’s fall gift.
