About Cast & Tide

Cast & Tide answers one question fast: what are the tides doing at my spot today? Each location page shows today's high and low tides, a 7-day tide curve, fishing and tidepooling windows, moon phase and daylight times — in a format readable in seconds on a phone.

All tide predictions come from the NOAA Center for Operational Oceanographic Products and Services (CO-OPS). Heights are relative to the MLLW datum and times are local to each station. Every page names the exact NOAA station it uses, so you can always check the source.

Astronomical tide predictions are deterministic calculations, not observed water levels. Actual water levels vary with weather — always check conditions before heading out.

The site is rebuilt automatically four times a day. No accounts, no tracking walls, no cost.

Editorial policy: every page is generated automatically from NOAA prediction data, and the build pipeline runs consistency checks on each one; we additionally spot-check pages by hand every week.
