October 18, 2018 Surf ForecastOctober 18, 2018, 5:00 AM HST · Updated October 18, 5:00 AM 0 Comments
Outlook through Thursday October 25: A large, long-period south swell arriving Friday, is expected to peak this weekend. Surf heights will likely reach the High Surf Advisory criteria starting Friday night along south facing shores. There is a possibility surf may approach the High Surf Warning threshold along south facing shores this weekend. This south swell will slowly subside early next week. The current north-northwest swell will gradually decline into this weekend. A new moderate northwest swell may arrive next Tuesday, and persist through mid-week. Surf along east facing shores will remain small into this weekend due to the weak trade winds.
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.
