Swell Summary
A series of small reinforcing northwest swells will keep north shore surf up above typical summertime flat levels through the remainder of the work week.
South shore surf will remain small and below the summertime average through the weekend, with mainly background southerly swells. A small south swell may boost south shore surf up close to the summertime average 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 Tropical Storm Hillary off Baja California could impact east facing shores during the middle of next week but still dependent on the size and intensity of the storm.
