Buoy Spectra

Important notes

  • If you don't know the difference between swell and surf, read Swell vs Surf
  • If you've never seen a spectra graph before, read Swell Spectra
  • The spectra graph on spot pages is generated by our global wave model. The spectra graph on buoy pages is generated from recorded observations at sea.
  • This feature is only available to our Premium and Forecast members

How do I find the Buoy Spectra?

From the Buoy report page, expand the Swell Spectra Labs graph highlighted below.

Why is this data useful to me?

Get a good rundown from our Director of Forecasting, Kevin Wallis here

  • Distinguish between mixed/messy/jumbled surf and clean/organized/lined-up surf
  • Will help you determine which kind of break (beach, reef, or point) you'll go surf
  • Distribution of energy across different periods (and the mean direction of each period)
