How to Graph Tide Data on Excel 2007

Updated April 17, 2017

Tidal curves are charts that show the daily times and heights of the high- and low-water marks for a particular location, along with all of the heights in between, expressed in the form of a smoothed curve. They are used by mariners and fisherman to determine both the safe times to leave and enter port along with the ideal times to begin fishing. You can create a tidal curve in Microsoft Excel with just a few clicks of the mouse.
