Swell Summary
Monday's large northeast swell reached its peak about 24 hours ago and has been on a steady slow decline. The swell still remains elevated enough today, at around 8 feet in the medium period spectral bands, to warrant a east-facing shore High Surf Advisory (HSA) in effect through the afternoon. North-facing shores will receive a small, medium period northwest swell through the day that will hold well below advisory level surf through Thursday afternoon. A larger northwest swell is scheduled to arrive late Thursday that will likely lift north surf up to HSA levels as it peaks out early Friday. Periods of very small, long to medium period south to southwest swell will keep south-facing shore surf from going completely flat this week.
