Outlook through Tuesday November 20: The new north-northwest swell is here, and will be building throughout today. Expect surf to max out at 14 feet, with occasional higher sets this afternoon. This surf range is expected for Wednesday as well. A reinforcing northwest swell with a 8 foot swell and a 14 second period, is slated to arrive Thursday night. This means potential high surf for the north and west facing shores once more. A smaller north swell will help reinforce this decaying NW swell over the weekend. Surf along east facing shores will be on the rise as well over the weekend with the stronger trades. Surf, though will be below advisory levels. The south facing shores will continue to feel a small background southerly swell during the forecast period.
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.
