About TideAhead

Coastal Planning With The Source In View

TideAhead makes official U.S. coastal information easier to inspect in one place. It is a planning aid—not a navigational product, emergency service, closure notice, or substitute for local conditions.

Official Sources First

TideAhead uses NOAA CO-OPS for tide predictions and available water sensors, the National Weather Service for observations and model forecasts, and the U.S. Naval Observatory for astronomy.

No Invented Replacements

Unavailable official fields remain unavailable. Sensor observations and model values are labeled, and subordinate-station curves are bounded interpolations between official extrema—not extrapolations.

Commercial Independence

Ads and sponsors never control environmental values, source labels, safety notices, activity analysis, or which official links visitors see.

How To Read A TideAhead Page

Station IDs, datum, update time, availability, and provider links appear beside the values they support. “Observed” means an official sensor report. “Model” means an official forecast or grid value. A mixed badge means the display combines both.

Activity scores are TideAhead planning analysis built only when the required current official inputs exist. They do not predict catches, verify access, or override regulations and closures.

For the full provider inventory and known coverage gaps, see the source links on each station page. Start with the Washington tide-station guide or use national search.
