Swell Summary
Surf along north facing shores will gradually lower into Tuesday due to a persistent short-to-medium period mix of north-northwest to north-northeast energy moving through. A medium-period, moderate northwest swell will arrive and begin to build down the island chain Tuesday night through Wednesday. Expect this new swell to linger into the weekend before lowering. Surf along south facing shores will remain up today, then lower Tuesday through midweek as a south- southwest swell eases. A similar south-southwest swell will be possible late in the week.
