May 2026 — San Francisco / Bay Area: Halibut Peak, Striper Strong, Salmon Opener Talk. May is a late spring month with water in the 64-68°F range — PEAK yellowtail; white seabass; calicos active; first bluefin. Here’s the full breakdown of what’s biting, where to fish, and the most productive tactics.
What’s Biting — May 2026
Primary targets this month: Halibut, Striped Bass, Rockfish, Salmon.
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
Striped bass at 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 bait (eels, bunker), trolled tubes and parachutes, or surface plugs at the rips. Peak season — fish actively feeding.
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.
Salmon
Salmon on the Golden Gate area and Pacific Ocean off SF (May-October Chinook season, verify CDFW dates), Half Moon Bay, and Pacifica — when ocean salmon seasons are open (recent years have seen closures, verify). Mooching with anchovies/herring, trolled spoons/plugs on downriggers, or fly-lining bait. Verify CDFW current ocean salmon season — recent years have seen closures or short windows in California.
Water Conditions & Patterns
Water temperatures are running 64-68°F. Peak yellowtail; white seabass; calicos active; first bluefin. 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.
May Outlook
Late spring — tarpon arriving, snook moving, summer pelagic season building offshore.
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.
