The most recent swell observations at the far northwest offshore buoys are beginning to show that the large north swell that peaked yesterday has begun a slow and steady decline. Swell at both offshore NOAA 001 and 101 buoys are observing a near 10 foot, 12-14 second swell (versus near 20 feet, 15 seconds a mere 24 hours ago). Surf has fallen below High Surf Warning heights and therefore have lowered flags to a High Surf Advisory (HSA) that is in effect for all north facing shorelines through the day. The HSA for west facing shores has been allowed to expire as surf heights have fallen below 12 feet (8 feet Big Island). North shore surf will likely fall below HSA levels tonight and will fade to small heights from late Tuesday into the weekend.
Strong southerly winds within and near recently strong convergent overnight rain bands developing far east of a kona low northwest of Kauai have produced periods of rough, short period chop that will be impacting south facing shores today. The latest PacIOOS buoy at Pearl Harbor has shown a very significant spike in significant wave height from 3 feet a few hours ago to near 10 feet this 0300 HST hour. As high pressure builds in from the northeast later this week, strengthening trade winds will result in elevated rough wind wave surf along most east facing shores from mid week onward.
