Hello Lizzy14,
The National Data Buoy Center website has a map showing the locations buoys around the world. The markers on the map are color coded. The yellow markers indicate buoys with recently collected data. Orange and red markers are for buoys with historical data or with no data for the last 24 hours. For this project you should look for yellow-marked locations.
As indicated in the project procedure, not all yellow buoys have wave data. There are buoys with wave data in the Great Lakes, Maine, North Carolina and Southern California. You can navigate to these regions with the links on the right-hand side of the National Data Buoy Center page. For example, here is a link for a buoy off the North Carolina coast:

I hope this helps and good luck with your project. Please post again if you have more questions.
A. Norman
