...HIGH SURF ADVISORY FOR NORTH FACING SHORES...

Surf along north facing shores will be 12 to 18 feet today, lowering
to 8 to 12 feet tonight. Surf will then rise rapidly to 20 to 25 feet
Wednesday afternoon.

Surf along west facing shores will be 2 to 4 feet today through
Wednesday.

Surf along east facing shores will be 4 to 6 feet today, with locally
higher sets along shores exposed to the north swell. Surf will lower
to 3 to 5 feet tonight, then rise to 4 to 6 feet on Wednesday, with
locally higher sets along shores exposed to the north swell.

Surf along south facing shores will be 2 to 4 feet today through
Wednesday.

Outlook through Tuesday November 28:
The current advisory level north swell will linger today, then decline
tonight. Another large north swell is expected to build rapidly on
Wednesday afternoon, peak Wednesday night into Thursday, then slowly
decline Friday and into the weekend. A High Surf Warning is likely
with this swell for all islands with a northern exposure. Another
large north swell is forecast to arrive Sunday. Locally generated
swell from the strong gusty trade winds during the second half of the
work week may warrant a high surf advisory for the east facing shores
as well. Waters will be dangerously rough and choppy along with the
elevated surf. A series of small but long period south swells will
prevent surf from going flat along the south facing shores this 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.
