WXTide32

This program is one of those about which you can say "hmm...clever...I've never seen this before". It can tell us the exact tide level, even in real time.
WXTide32 features a complete database of sea stations worldwide, displaying their names, coordinates, type (subordinate or reference), region, country, and many more. You can easily locate the station nearest to you, in order to get the current tide level. You can filter stations by region, country, or US state. Even more, you can add your own stations in case they are not listed (I found mine).

The program comes with several window modes to display graphically the data in various ways: realtime, graph, overview, and clock. If you click over the window, you get the information related to that point (e.g. the tide level at a specified date/time). And, if you like the graphs, you can print them.
Moreover, you can specify a time window to get predictions, and generate text information in various formats, like daily tides, tide calendars or incremental tides.
If you like the sea, you are a sailor or just want to go fishing, maybe you will find this useful!
