Where to fish tomorrow,
before you leave the dock.

Tuna and striper heat-map predictions from Long Island Sound out to the offshore canyons. Built by a Cobia 28 captain out of Old Saybrook β€” the same tool I use to plan my own trips.

Fish Finder map showing zone heat scores for the Northeast US coast
Interactive chart: every zone scored 1–10 for tomorrow Β· updated nightly Β· fits your boat's range from your home port

Every morning, one answer.

Not a wall of data. Not a weather dump. A specific spot, backed by every signal that matters β€” matched to your boat and tomorrow's conditions.

πŸ—ΊοΈ

27 zones, scored 1–10

Every named tuna and striper spot from LI Sound to Veatch Canyon gets a fresh heat score every morning. Ranked by what's biting AND what should be biting.

β›½

Fits your boat

Enter your home port, tank size, and MPG. Every zone shows nm, fuel round-trip, and % of tank β€” with a red flag on anything past your safe range.

🌊

Real weather cap

Wind and wave thresholds you set. Days that break the cap are marked stay-home. The picker automatically points you at the next fishable day.

πŸ‹

Whales & bait signals

Whale/dolphin sightings from CRESLI & Viking Fleet. Bait intel from captain reports. Where the bait piles up, the tuna follow β€” usually within days.

🌑️

SST + chlorophyll edges

The 68–72Β°F break line and the blue-green chlorophyll edge, both overlaid on the chart. Fish the water in between β€” that's the tuna sweet spot.

πŸ“š

Gets sharper over time

Every night the picks + conditions get archived. Feedback on what actually bit tunes the model. A year from now it'll know your patch better than any static chart.

Eight signals, one score.

Everything below feeds a single effective-heat number that decides tomorrow's pick β€” the way you'd think about it if you had the time to check every source.

Why I built this.

I fish out of Old Saybrook, CT in a 28' Cobia. Every trip is a bet: fuel, time, hope. I got tired of running 60 miles to a spot that "should have been good" because the report I read was three weeks old.

So I started keeping notes β€” where the whales were, what temperature the breaks sat at, what the bait was that week. Then I got tired of doing it by hand and built Fish Finder: a nightly-updated chart that predicts where to fish tomorrow, before I leave the dock.

It's free, it fits your boat, and it works for anybody fishing between Long Island Sound and the offshore canyons. If you want in on the beta, drop your email below.
