The tide hindcasts/forecast calculated here use tidal constituents from the Oregon State University global tide model
which is based on measurements by the
The computational grid of the model is 1/12° in latitude and longitude, which corresponds to about 10 km in the N/S direction and about 7 km in the E/W direction.
If you select a location that is on land, the program will find the nearest node on that parallel that is in the ocean.
