Key Largo
Florida Keys

Diving capital of the US. Crystal-clear tropical water, shallow patch reefs, and deep wrecks including the Spiegel Grove and Duane. Consistently 30–80ft viz in summer, more volatile in winter.

Islamorada
Florida Keys

Sportfishing capital of the world. Deep water close to shore, the edge of the Gulf Stream within a short run. Sailfish winter push, mahi summer runs.

Key West
Florida Keys

Southernmost reef structure in the continental US. Marquesas and Dry Tortugas trips for permit, tarpon, and offshore pelagics. Shallower patch reefs inshore for snapper and grouper.

Jupiter
Southeast Florida

Deep ledge runs just offshore, plus the inlet drift for big snook and tarpon. Strong Gulf Stream influence — pelagics push close in when conditions align.

Pompano Beach
Southeast Florida

Shipwreck alley — dozens of intentionally sunk wrecks within 20 minutes of the inlet, plus the world's largest artificial reef project. Year-round diving, reliable sailfish in winter.

Miami
Southeast Florida

Haulover, Government Cut, and the edge of the Gulf Stream just minutes offshore. Sailfish, kingfish, and mahi runs year-round. Bonefish flats in Biscayne Bay on the back side.

Daytona Beach
Northeast Florida

Surf-fishing paradise with long stretches of accessible beach. Offshore runs to ledges for snapper, grouper, and seasonal kingfish.

Tampa Bay
West Florida

Massive estuary with tarpon runs in May–July, redfish and snook year-round in the grass flats, and offshore depth for grouper within 30 miles.

Destin
Florida Panhandle

"World's luckiest fishing village." Deep water closer to shore than most Gulf ports. Red snapper mecca in season, cobia push in spring, offshore tuna trips year-round.

Naples
Southwest Florida

Inshore snook and tarpon fishing, plus the run to the Middle Grounds for serious offshore trips. Easy-bottom Gulf of Mexico inside 20 miles.

How Submarius handles fishing

Every location page shows the same thing: live wind, swell, tide, and bite-score data pulled from free public sources (Open-Meteo Marine, NOAA, NOAA Tides) — aggregated into one verdict you can read in a second. Every factor is tappable for the full reasoning. No black-box AI claims.

Water clarity forecast

How the Submarius clarity model works — satellite data, river plumes, and post-dive reports.

Bite score

What the 0–10 number means, which signals it uses, and why most other bite scores are wrong.

Fishing app

The full pitch — what Submarius does for fishing and how it compares to other apps.

Common questions

What does the Bite Score use?

Tide stage and range, moon phase and position, solunar major/minor windows, barometric trend, wind, and water temperature. Every factor is transparent — tap any tile in the app to see the number, reasoning, and 24-hour trend.

Does Submarius cover saltwater and freshwater fishing?

Our primary focus is coastal saltwater — where wind, swell, and marine-forecast signals matter. Inland freshwater fishing is not our core use case; for lake-specific bass intelligence, apps like Fishbrain have deeper catch-data moats. We serve anglers whose decisions depend on marine conditions and tide/moon windows.

Is there a free tier?

Yes. Current conditions, a 2-day forecast, basic bite score, and all safety features are permanently free. Pro ($12.99/mo, $99/yr, or $149 lifetime) adds the 10-day forecast, premium map overlays, offline maps, and advanced bite-score layers.
