Swell Summary




Surf along south facing shores will remain slightly below average through Thursday. A long period south-southwest swell generated from gales just south and east of New Zealand will begin arriving late Thursday into Friday, boosting surf to near average. Surf along east facing shores will continue to fade as background flow becomes weaker, then build heading into this weekend as the trades restrengthen. North facing shores will remain tiny through Friday, with a slight bump from Lala swell possible this weekend.
