The Count

The chart above tells the whole story in one frame. Berkeley California halibut counts went 24 → 11 → 44 → 71 → 59 across the past five weeks — a sharp dip in early April, a clean 6× recovery off the mid-month low, and 59 fish already in the bag through April 29 with the current week still rolling.

The flip on California Dawn II (California Dawn Sportfishing) is the cleanest signal: on April 7 they ran 36 stripers and 2 halibut. By April 26, the same boat's count was 15 halibut and 11 stripers. Same dock, same captain, same skiff lanes — the fish changed.

Striper season isn't over, but it's no longer the headline. Berkeley striper counts went 216 → 176 → 170 → 51 over the same window — the big push spawned in early April; what's left in the Bay is scattered. If you're booking Berkeley this week, book it for halibut and treat any bass you catch as bonus.

A note on the leaderboard: California Dawn II, California Dawn, and Gatherer II report fish as "California Halibut" — that's the chart above. Happy Hooker and Pacific Dream report the same species as just "Halibut" in the dock count, so they don't show up in this view. Combined across both labels, Berkeley landed 82 halibut last week (71 + 11). It's a labeling quirk, not a data gap — both fleets are fishing well.

Conditions When the Bite Was Hot

The bite picked up exactly when the bait did. Capt. James Smith Jr. (California Dawn Sportfishing) flagged the first signs of anchovies in mass on April 10, and the Happy Hooker called out "a lot of bait" on April 15. Live anchovies out of Davey's Live Bait at Berkeley Marina K-Dock have been the standard offering — flatties pin themselves in the sand and ambush whatever drifts by.

Water in the Bay has warmed past 59°F at the SF Bay Bridge buoy this week — within striking range of the 60°F threshold where halibut start moving aggressively into the shallows to feed. Swell outside the Gate has bumped up to 4–5 feet at an 11-second period, but that's almost nothing on the Flats — Berkeley sits well inside the wind and swell shadow.

The tide swings have been doing the work. The full-moon week is bringing 6+ ft tidal sweeps with corresponding minus lows. Strong tide = strong drift = halibut feed hard on the moving water.

7-Day Forecast

Friday is the standout. Full moon, 5.6 ft tidal sweep from a -0.47 ft minus low at 06:48 to a 5.11 ft high at 13:25, and just 6–9 mph SW wind through the day. That's a lay-up. Thursday is nearly identical and gets you out a day earlier if your weekend is locked.

The weekend turns. Saturday and Sunday push 10–13 mph WSW with partly cloudy skies — drift speed picks up, you'll need to slide more weight to hold bottom in the chop. Still fishable, just harder. Monday has a slight chance of light rain and wind backs off to 8–10 mph SW; if your only window is Monday, it's not a no-go, but you'll be working for it.

Tide protocol: aim your drift to start about an hour before the high. Berkeley Flats works best on the back half of the incoming tide as the water pushes onto the shallow sand. The Thursday and Friday afternoon highs (12:36 and 13:25) line up perfectly with morning bait pickups out of K-Dock — load up, idle out, drift the back half of the flood.

Every condition box matches except the moon — and the upgrade from waxing gibbous to full moon means bigger tides, not worse fishing for Bay halibut. Use the moon as a tide multiplier, not a threat.

What Anglers Are Saying

A few patterns to read into the quotes above. First, "over 40 shorts thrown back" — that's a classic spring migration signal. Juvenile halibut moving in alongside the adults means the population is genuinely shifting into the Bay, not just a few resident fish. The shaker ratio will drop as keepers settle in over the next two weeks. Second, every captain mentions bait. Anchovies in mass = halibut on the feed. If the chovies hold, the bite holds.

Across the Bay, the freshest data point is from Fish Emeryville on April 29: Oakland Anglers II logged 12 stripers + 10 halibut with 9 anglers, and Scallywag posted 12 stripers + 7 halibut to 10 lb with 6 anglers. That's halibut at over a fish per rod across two boats on the same day — a clean validation that the Bay-wide bite is on, not just at Berkeley. The same week, Lovely Martha out of SF Wharf was filing limits of bass plus quality halibut — proof the bite spans the entire Bay.

One thing the dock counts won't show: salmon just reopened. California's recreational ocean salmon season opened April 11, 2026 south of Pigeon Point — the first meaningful season after total closures in 2023 and 2024 and just six open days in 2025. Some HMB-departing boats are already returning with kings. Halibut is the inside-the-Gate play; salmon is the outside-the-Gate play. If you've been waiting on the Bay, this week is also the strongest salmon window most anglers have had since the 2022 season ended.
