A tide calendar similar to the iconic Tidelines tide calendars built in D3. Data was obtained from NOAA.
If you've never experienced the awesome surfy-ness of a Tidelines calendar, I sincerely encourage you to purchase one. They have beautiful photos and wonderfully clean design. I am not affiliated with Tidelines but I did grow up with one of these calendars on the wall of my parents' house (they still buy one every year).
