.DISCUSSION...
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.
