Click on swell plots for the open ocean swell data. Click on surfplots for the derived potential potential surf heights.

The surf plots can vary from the text and that is because the same data point and used for the nearby east facing areas.

In any case, Cape May faces south. As mentioned, the more N in the swell direction the more swell will bypass the cape. The swell window there is basically 90(E) to 180(S) degrees. A lot of the nor'easter type systems we have produce at 45(NE) to 80(ENE) degree swell. This mean the swell will bypass cape may, but if there is enough east in the swell, you can see some size get in there. If there is a sizeable NE/ENE swell, swell will refract (bend) into the cape.

As mentioned earlier, use the forecast as guidance, and hopefully you can learn by looking at the forecasted swell direction and such. The forecast is no way going to be able to capture all of the variability at cape may. Tides are crucial there... Sanbars play a big roll as well. Last time I surfed there, the sand at a particular break was really bad. Also there are several places to surf on Cape May (different beach facing directions), all of which react differently to different swells.
