After download, rename file so it has a .ics extension. Then you can drag it to the Calendar app in the dock or import it into a Google calendar.

About

Uses data from Provincetown (not Wellfleet). Provincetown is hopefully the best harmonic station to approximate Wellfleet's tides. For a list of other harmonic stations see NOAA's list.

Note there is some randomness in the calculation, so refreshing the page can yield slightly different results.

Developed by Lee Danilek. Please email the developer with bug reports, comments, etc.

Calculations are based on source code of Pytides, with code rewritten so it can be run online. Tide constants data are from noaa.gov
