Buoys and Charts

Charts

From any Spot or Regional page, click CHARTS just below the page's title. There are several different types of charts, but the default product is the significant wave height chart, so we’ll primarily discuss that popular chart in this feature.

The significant wave height chart displays wave heights over an area of interest in the ocean or large body of water (including the Great Lakes).

The colors on the map/chart can be deciphered using the scale at the bottom of the image, which indicates wave height and unit of measurement. The white directional arrows indicate the direction the waves/swell are traveling towards, so you’ll know if that purple blob is heading your way or elsewhere.Screenshot_2021-11-11_at_13.03.31.pngScreenshot_2021-11-11_at_13.05.34.png

To scroll through time, mouse over the light and dark gray boxes or use the play/pause buttons at the top of the image. Use the left hand rail to browse from the local to the global scale

 

Other chart types are listed on the left hand rail. These charts all have the same functionality as the significant wave height chart described above, although the data displayed is unique. Happy charting and we’re hopeful that this helps you score bigger and better surf!

 

Buoys

From any Spot or Regional page, click on “Buoys” just below the page’s title.

You’ll be taken to a map page, in which you can either scroll through a list buoys on the left-hand side of the page, or determine your area of interest using the map on the right hand side of the page. Buoys within the map's reach will be listed on the left hand side of the page.

Right below the buoy’s title and identification number, you’ll see a date and time which indicate the last report we received from the buoy.

The largest reading in bold is the significant wave height. Individually sorted swells are listed to the right in a smaller font.

Tip — from any Spot page, "Nearby Buoys" are listed at the bottom of the page below swell, wind and tide graphs
