Swell Summary
The High Surf Advisory (HSA) has been extended in time for the north and west-facing shores of the smaller islands and is now in effect through Monday afternoon. This is a result of this morning's passing northwest (320 degree) long period swell. Resent nearshore buoy observations indicate that this long period (15-17 second) 7 to 8 foot swell is already a couple of feet above guidance. This swell will peak today and result in solid HSA level surf through Monday as it forecast to be slow to subside. The next north northwest (330-350 degree) swell will be on the heels of today's swell, generated from the hurricane force low mentioned above, and is scheduled to arrive late Monday and peak Tuesday. This large, long period swell will likely drive surf heights to above High Surf Warning thresholds Tuesday. This large swell should slowly decline from Tuesday night through the remainder of the week as it veers more northerly. Strengthening trades should increase eastern exposure chop and lead to rough surf from Tuesday into the middle of the week. Small background swell leading to very small surf will continue along south-facing shores throughout the week.
