Swell Summary
A series of north-northeast and northwest swells are due this week. A tiny northwest swell will peak at around 2 feet late tonight through Friday. A moderate northwest swell will build late Saturday, peak Sunday, and decline Monday, followed by a smaller pulse on Tuesday. A medium period north swell will slowly build tonight and Thursday, and hold at 4 to 5 feet Friday and Saturday. A very deep storm off the U.S. Pacific Northwest coast will send an overlapping pulse of north-northeast swell late Saturday. This swell will peak Sunday into Monday, then drop off on Tuesday. None of these swells is expected to produce advisory level surf, but we will monitor buoys for the potential of high surf on north and east shores from the pulse of north-northeast swell.
As trade winds and the associated easterly wind wave energy steadily drop, east shore surf will decline through Friday, then fade out during the weekend. Surf along south facing shores will remain small through the week.
