Striped Bass
Morone saxatilis
Season: May – October
Baits: Anchovies, Topwater plugs, Swimbaits
Work troughs and rip currents on a moving tide. Dawn topwater in flat surf is the classic bite.

California Halibut
Paralichthys californicus
Season: April – September
Baits: Live anchovies, Swimbaits, Hair raisers
Drag baits slowly along sandy bottom near structure edges. Slow retrieve — halibut ambush from below.

Rockfish
Sebastes spp.
Season: April – December (check regs)
Baits: Shrimp flies, Metal jigs, Squid strips
Fish vertically over reef and kelp. Keep the bait just off bottom to dodge snags and hook quality grade.

Leopard Shark
Triakis semifasciata
Season: May – October
Baits: Squid, Mackerel chunks, Midshipman
Soak fresh bait on the flats during an evening incoming tide. Steel or heavy mono leader, circle hooks for a clean release.

Barred Surfperch
Amphistichus argenteus
Season: Year-round, best in winter–spring
Baits: Sand crabs, Gulp! sandworms, Motor oil grubs
Carolina rig in the first trough behind the shorebreak. Follow the tide in — perch feed where sand crabs wash out.

Rod & Reel Combos
Daiwa D-Wave Saltwater Spinning Combo — 8 ft, 2-Piece Medium
Eight feet is the honest middle: long enough to keep line above the wash on a gentle beach, short enough to fish from a pier or a boat without apologising to anyone.

Line & Leader
Sufix 832 Advanced Superline Braid — 20 lb, 300 yd
Seven HMPE fibers plus one GORE Performance Fiber, braided at 32 picks per inch. The GORE fiber is what makes this line quiet through the guides and stubborn…

Terminal Tackle
Eagle Claw Lazer Sharp Offset Circle Sea Hook — 4/0, 50-Pack
The circle hook does the work for you: no strike, just let the rod load and the hook finds the corner of the jaw on its own.
Terminal Tackle
MO's Bank Sinkers — 4 oz, 20-Pack
Four ounces is the weight most 9 to 11 foot surf rods are built to throw, and the one to reach for when the water is moving hard enough that a 3 oz starts walking.
