No short shortage of swell on tap across the West Coast with a building trend in SSW swell underway over the weekend. The immediate outlook sees Thursday’s mid range SW pulse dropping back into 2-3ft+ range across South Coast open breaks by Friday. Early light SSE winds will see the best conditions ahead of a shift to the SSW during the afternoon.
A moderate, long period SSW groundswell picks up over the weekend as a broad fetch pushes into the Bight. For most breaks, the south angle of the swell would limit refraction, causing inconsistency between sets. Increasing set waves should begin to show during Saturday afternoon and peak into Sunday. Swell shadowing would likely cut down swell size as well so expect waves to be wrapping in around the 3-4ft range.
However, open breaks exposed to the S angle and focusing the longer period swell energy would pick up larger 4-6ft+ sets as the swell peaks into Sunday. Keep in mind the swell direction would differ from Thursday's more westerly and shorter period WSW pulse. Weather conditions could see light winds through the weekend so get amongst it as the swell builds.
