Tidal height prediction software for the PC

Neptune Tides is an easy to use tidal height prediction program covering 347 UK and 312 European ports. It displays the daily curve, the instantaneous rate of rise or fall of the tide in metres per hour, sunrise and sunset times, lunar phases, a springs to neaps indicator, and monthly tide times and heights.

Advanced functions let you display and experiment with the astronomical tide raising forces. That makes it useful for teaching and for understanding complex tidal patterns, because it becomes obvious why some ports have stands, or double highs and lows.

Version 9.3 adds an improved port search, daylight savings, and Excel friendly clipboard and file output. No annual updates are required and the program predicts to the year 2060.

Windows may warn you, or look as though it has blocked the file, before it will let the installer run. That is because our installers are not code signed, not because there is anything wrong with them. Choose Keep, then More info and Run anyway. Step by step, with screenshots.
