December 19, 2018 Surf Forecast
Outlook through Wednesday December 26: The current large north-northwest swell will hold through the morning hours, then slowly decline this afternoon through the end of the week. Several small northwest swells are expected Friday through the weekend, with a new small to moderate west-northwest swell possible early next week. Strong north to northeast winds will bring choppy short period surf to east facing shores today and tonight. Moderate trade winds will then keep surf slightly elevated along east facing shores Thursday through early next week.
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.
