Swell Summary
Surf along north facing shores will remain small through Tuesday. A new short period north-northwest swell will then give north shore surf a boost during the middle of the week, with a slow decline expected Friday through the weekend. Head high to slightly over head sets can be expected along north facing shores as this swell peaks, but surf will remain well below advisory thresholds.
East shore surf will remain small through the next 7 days, although we should see a slow trend upward Thursday into the weekend as the trades over and upstream of the islands strengthen.
Surf along south facing shores will remain small during the next 7 days, with mainly background south and south-southwest swell energy moving through.
