There are a few tide locations in our database that are not available. If you are looking for a tide prediction from a particular location and it is not available in our script, please let me know and I'll look into adding it. Also, if you find one that's not being displayed when you click the link, let me know.
We're very excited about this new capability at Go Fishing Forum and hope that you will get some good use out of it. Remember that the predictions are for reference and planning purposes only! If your life depends on the prediction being correct, then go talk to the folks at NOAA!
Good luck out there!
