Point well taken Chris. Here's another tidbit related to swell intervals. Swell period matters as much as direction at the launch. A four foot northwest swell with a 5 second period will pound the launch. Same swell direction with a 15 second interval will leave the launch virtually untouched. (Usually) This is due to the bathymetry of the ocean floor. The energy in a long period swell reaches much deeper under the surface of the water and the energy can then be funneled into certain areas according to the bottom contours.

For example, on a long period northwest swell, the launch might be flat and scripps overhead. On a short period swell there is not as much difference in size, although scripps will still be bigger.
