Official predictions, stored locally

Every table is NOAA's own harmonic prediction for a named station, fetched by this site's import jobs and served from its database, so pages stay up when NOAA is busy. Each page says when its data was retrieved.

A station, not a town

Tides differ across a channel or an inlet. Pages are for specific NOAA stations, with their id, zone and datum shown; nearby stations are listed with distances so you can choose.

Not for navigation

Predictions are estimates of astronomical tides; weather, storm surge and river flow change real water levels. Not for determining safe clearance. Use official charts, observations and forecasts.
