Swell Summary
Small northwest swell will keep north shore surf up above typical summertime flat levels today as it slowly fades this weekend. South shore surf will remain small through Saturday with a slight reinforcement Sunday into early next week.
East shore surf will remain below normal levels through the weekend due to lack of strong trades upstream of the island chain. Long period east swell generated from Hurricane Hillary off Baja California could impact east facing shores beginning Monday night or Tuesday.
