surf along east facing shores will be 1 to 3 feet through saturday,
except 5 to 7 feet tonight through saturday for locations with a
northerly exposure.

surf along south facing shores will be 1 to 3 feet through saturday.

outlook through friday january 24:
surf along north facing shores will trend up over the weekend, then
remain up through next week as a series of north to northwest swells
move through. heights may reach advisory levels beginning as early as
sunday along north and west facing shores. a more significant
northwest swell is possible by midweek, which could lead to near warning-
level surf for north and west facing shores. choppy surf will return 
along east facing shores by the end of the weekend as the trades fill 
back in. surf will remain small along south facing shores with mainly 
background south-southwest swells expected.

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.
