About TidalMap

We believe that when people truly understand the water around them, they make better decisions, catch more fish, and become better stewards of our coasts.

TidalMap — built by Adcountant LLC.

At Adcountant LLC, we believe that understanding the water around you changes everything. We organize complex marine and environmental data into intuitive, field-ready tools so anglers and coastal professionals can focus on what matters — time on the water.

Best available data, wherever it lives

We collect and display the publicly-available data that's useful to fishermen, straight from the source — NOAA tides and sea-surface temperature, USGS streamflow, NWS wind and swell, USCG hazard notices, and TVA dam releases. Every overlay answers one question: given your spot, what's the best signal we can show right now? A subordinate tide reference at your inlet beats a gauge 30 km away on a different tidal regime — accuracy first, then proximity, then freshness.

From the Crystal Coast, for every coast

TidalMap was born on North Carolina's Crystal Coast — Swansboro to Harkers Island — the founder's home water. But the data doesn't stop at a state line: coverage runs continental and offshore, and grows as each upstream source expands. Inland counts too — trout fishermen on tailwaters and gauged rivers are first-class users, with live discharge and next-day dam-release data sitting right next to tide and surf.

Not for navigation

TidalMap is for information and recreation. It is not a navigational tool and should never replace official NOAA charts, proper aids to navigation, or sound seamanship. The captain is always responsible for the safe navigation of their vessel. See our Terms of Service for the full disclaimer.
