December 27, 2018 Surf Forecast
Our weather team will bring you any urgent weather alerts or updates as they occur. Check our breaking news section for the latest.
Outlook through Thursday January 03: Surf will begin to rise by the end of the day today, potentially reaching warning levels tonight through Friday along exposed north and west facing shores as a larger northwest swell fills in. This swell gradually lower into the weekend, but a series of west- northwest swell is forecast to arrive next Monday and peak Tuesday night with surf at or near advisory levels for the north and west facing shores. Strong, persistent trade winds east of the islands has generated an easterly swell that will keep the surf up along east facing shores even as the trades become light and variable over some parts of the island chain during the next couple of days. Moderate to strong and gusty trades will return over the weekend, and this will bump the surf along east facing shores to near 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.
