September 24, 2018 Surf Forecast
Outlook through Monday October 01: Surf will remain below advisory levels along all shores through the week. Bumpy, short-period surf along east facing shores will gradually decline throughout the week as the winds ease and shift more southerly. An increase in wind swell is expected over the weekend as trade winds return. A small north-northwest swell is expected late Thursday into Friday. This swell is expected to peak on Saturday and hold through the weekend. Small southwest and south swells will give surf along south facing shores a small boost throughout 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.
