Select a region here, then from that page, select a site for which to generate predictions. You will get basic predictions and a form for customized predictions. Predictions may take a few moments to calculate, please be patient. Please see the FAQ (Frequently Asked Questions list) if you cannot find the site you want.
NOTE: Any site name ending in “Current” will generate predictions of current speeds; all other sites generate tidal height predictions. There are many more locations for tidal height predictions than for current speed predictions.
