How Submarius handles surfing

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.

Common questions

Why a surf mode in a diving app?

Submarius reads the same ocean — swell, wind, and tide are the signals surfers, divers, and spearfishers all need. Surf mode reweights the verdict around swell size, period, direction, and wind cross/offshore flavor.

How does Submarius compare to Surfline?

We don't offer cams — Surfline has hundreds of camera spots and that's their moat. Submarius focuses on the forecast verdict and honest uncertainty, with safety features permanently free. Use the right tool for the moment.

Is there a free tier?

Yes. Current conditions, 2-day forecast, and all safety features are permanently free. Pro ($12.99/mo, $99/yr, or $149 lifetime) adds the 10-day forecast and premium overlays.
