April 2026 — San Francisco / Bay Area: Halibut Opens in Bay, Striper Strong, Rockfish in Season. April is a spring month with water in the 62-66°F range — yellowtail building; white seabass arriving with squid spawn; calico bass. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics.
What’s Biting — April 2026
Primary targets this month: Halibut, Striped Bass, Rockfish, Lingcod.
Halibut
California halibut on SF Bay (California halibut — 30 ft to 80 ft depths), Berkeley flats, the South Bay flats, San Pablo Bay, and the open ocean off Half Moon Bay. Live bait (anchovy, smelt) on Carolina rigs slow-trolled along sandy bottom; soft plastic swimbaits hopped along the bottom. 20-30 lb tackle.
Striped Bass
Striper around the SF Bay-Delta system (one of the largest west-coast striper populations), the Sacramento and San Joaquin Rivers, Suisun Bay, the Carquinez Strait, the Bay Bridge area, and the Berkeley flats. Live and chunked bait; bucktails and soft plastics on lighter tackle.
Rockfish
Rockfish on the offshore rocky bottom — the Farallon Islands, the Pacifica reef, Half Moon Bay rocky bottom, Cordell Bank — black, blue, vermilion, copper, and yelloweye. Drop 6-10 oz iron jigs or shrimp flies on a multi-hook rig to the bottom in 100-300 feet. Multiple species in a drop — vermilion, chili pepper, copper, china, and the occasional lingcod.
Lingcod
Lingcod on the rocky bottom of the Farallons, Pacifica, Half Moon Bay, and Bodega — 100-300 ft depths. Large swimbaits (8-10″), live bait (small rockfish, mackerel), or big iron jigs. They hammer baits aggressively. Stout tackle (60-80 lb braid) to lift fish off structure.
Water Conditions & Patterns
Water temperatures are running 62-66°F. Yellowtail building; white seabass arriving with squid spawn; calico bass. SF Bay has massive tidal flow (6-7 ft on big tides) — the entire Bay-Delta is tide-driven. Halibut bite best on the moving tide; striped bass at the Carquinez Strait push hard on outgoing tide. The Farallons and offshore rockfish/lingcod fishing is driven by ocean conditions and current rather than tide; check Cordell Bank for wind windows.
Check the NOAA marine forecast and tide charts before launching. Wind direction often matters more than wind speed for inshore fishing — clean water beats churned water nine times out of ten.
Tactics & Tackle for This Month
- Water temperature is everything. Yellowtail like 64°F+, white seabass like 60-65°F squid spawns, bluefin tuna 68-72°F.
- Live bait priority. Bait quality determines success — buy active anchovies and sardines from the bait barge, use them quickly.
April Outlook
Peak spring migrations — cobia (Gulf/SE), striped bass (mid-Atlantic), spawning movements everywhere.
Regulations Reminder
Striped Bass: Federal slot typically 28-31″ with state variations; verify ASMFC and state rules annually. Rockfish/Lingcod: CA seasons highly variable by depth zone — verify CDFW current rules. Lingcod 22″ minimum. Always verify current state regulations before each trip — slots, bag limits, and seasons change.
