September 23, 2018 Surf Forecast
Outlook through Sunday September 30: Surf will remain below advisory levels along all shores through middle of the week. Rough, short-period surf along east facing shores will gradually decline throughout the week as the winds ease and shift. The first north-northwest swell of the season is expected late this week, which could bring near-advisory level surf along north facing shores. Small southwest and south swells will give surf along south facing shores a small boost through middle of the week, but remain well below advisory level.
Surf heights are forecast heights of the face, or front, of waves. The surf forecast is based on the significant wave height, the average height of the one third largest waves, at the locations of the largest breakers. Some waves may be more than twice as high as the significant wave height. Expect to encounter rip currents in or near any surf zone.
