ROSE PLOTS

Wave rose

The data of the selected time period is categorized by peak wave direction and significant wave height. The length of a petal (or a portion of the petal), corresponds to the frequency of occurrence.

The peak wave direction categories (degrees clockwise from True North):

  • 11.25 - 33.75 (centered at 22.5)
  • 33.75 - 56.25 (centered at 45.0)
  • 56.25 - 78.75 (centered at 67.5)
  • ...
  • 349.0 - 11.5 (centered at 0.0)

The color coded significant wave height categories (meters):

  • 0-1
  • 1-2
  • ...
  • 9-10
