This one is on the Lahaina side instead. Molokini on the background.

1) the bigger and longer period a swell is, the more it has the ability to wrap around land points (the south tip of Lanai in this case) and change its direction
2) the direction indicated by a buoy is only the dominant one: the one associated with the most energy, but there's energy coming from a range of direction around that number.
Remnant of typhoon Trami raced from near Japan 9/30 to the Bering Sea 10/1. The fetch area of strongest winds was not well aimed at Hawaii. Low, long-period swell from 290-310 degrees is expected to build on Friday. The dominant swell starting late Friday into Saturday is from the fetch of severe gales that hugged the NW Pacific south of the Aleutians 10/1-3. The fetch aimed just NE of Hawaii, though angular spreading should bring in surf locally. It should pick up Friday afternoon from 315-330 degrees, peak Saturday, then drop on Sunday from the same direction.
- a wide one in the NW corner
- Walaka's one that now is from the NW
- the windswell one
- an E one associated with hurricane Sergio
No shortage of waves any time soon on the north shore
