2009 Water Level Tidal Predictions

This system will allow you to obtain tidal predictions computed by CO-OPS for more than 3,000 water-level stations. The publication of full daily predictions is limited to fewer stations. These stations with full daily predictions are referred to as "reference stations." The remaining stations are referred to as "subordinate stations." Tidal predictions for subordinate stations can be obtained by applying specific differences to the times and heights of tides of the specified reference stations.

These pages provide a listing of the 3,000-plus subordinate stations with the differences already applied. These differences are located in the prediction header. The list of subordinate stations has been broken down into states and other areas where water-level stations are located. Each state is further broken down into regions. Each region presents a list of the water-level stations in the area. The stations are listed geographically; thus, stations that are near each other along the shoreline are near each other in the listing. This simplifies locating a station of interest.

A description of the information provided in this section can be found by clicking on the Question Mark symbol found throughout the listing of subordinate stations.

Bookmarks/Links:
Bookmarks/links may be created to the daily predictions for specific stations using the URL listed when the predictions for that station are displayed. Bookmarks/links may also be created to the station listings for a region. However, that bookmark/link will only provide access to the predictions for the year available when the bookmark/link was created. Each successive year of predictions will use a different URL, and thus any bookmarks/links must be updated to access each new year of predictions.
