.DISCUSSION...
Surf along south facing shores will remain slightly below average
through at least Friday morning, with near average heights possible by
Saturday as a south-southwest swell trickles in. Surf along east-
facing shores also remains below average, then is expected to build
this weekend as the trades restrengthen. North facing shores will
remain tiny through Friday, with a slight bump from Lala swell
possible this weekend.
Surf along east- and south-facing shores will be compounded by a
southeast swell generated by Tropical Depression Two-C that will build
through Sunday and then become south, then southwest through early
next week. This short-period tropical swell could cause surf to
approach advisory levels along east facing shores of the Big Island
Saturday night into Sunday.
