.DISCUSSION...
A series of small, medium period south (170-190 degree) swells
are expected throughout the week with surf holding near the summer
average. Surf heights should decrease Sunday into early next week
as these swells fade. Choppy conditions will continue for east-
facing shores through the forecast period due to the persistent
fresh trades. Meanwhile, expect surf to be nearly flat along north
facing shores.

apart. Expect to encounter rip currents in or near the surf zone,
with rip current strength increasing with surf size. Swimmers are
urged to exercise caution at all times and enter the water near a
