This is a pro-level page focused on providing a high definition view of the primary and secondary swells in the water at the buoys location. The algorithms used for these computations are different than those used on our main buoy pages and are a little more generous, meaning they accumulate more energy resulting is slightly higher swell and surf heights. The Column labeled 'Surf' and the Surf Graph display estimated surf size that could result from either the primary or secondary swell over the past 96 readings (4 days for NOAA Buoys, 2 days for CDIP buoys). Surf size will vary based on bathymetry, swell direction, shadowing etc at each surf break in the window serviced by the buoy. The column labeled 'Chop' is the significant wave height of all energy in the water between 2 and 5 secs. It is an attempt to provide an index of how much short period 'bump' is in the water. The spectral density graph displays the swell height in feet of the energy present in each frequency/period. A rough guide is that surf height for any frequency is about 1.5 times the value indicated on the chart. So if a third swell is present but not displayed in the webpage, one can estimate the resulting swell size. Clicking on the Spectral Animation link will display the last 96 spectral density graphs in chronological order (older to recent). Click the Current image link to return to the most recent graph.

It is assumed the user understand where these buoys are located and the effects of bathymetric features on resulting surf size at their favorite breaks. More buoys will be added in the future, but limited to those in the United States serviced by NOAA and CDIP. The focus is on areas of significant sized surf and are presented mainly to support our independent forecast projects unrelated to this website.
