Swell Summary
Small short period NW swell has been slow to arrive this afternoon but should bring elevated surf this evening into tonight for favored exposures. A long period NW swell arrives late Wednesday and peaks Wed night into early Thurs.
A small long period S swell has likewise been slow to arrive with long period energy just barely registering on the Barber's Point PacIOOS buoy. S swell energy remains at background levels into the weekend before a medium to long period SSW swell builds late Sunday into early next week. Slightly elevated surf along E facing shores continues until trades weaken this weekend.
