Sunday 9 19 21 morning call

Hookipa yesterday morning.

4am Surfline significant buoy readings and discussion.
South shore
2.2ft @ 13s from 288° (WNW)

It only takes a little of NW energy to wrap in the south shore of Oahu and possibly mask whatever small southerly energy is in the water. That's the case today and in the absence of the Lanai buoy, the only way to know what's really in the water is the Lahaina webcam. Check it if interested, for size, conditions and consistency.

North shore
2.5ft @ 12s from 359° (N)

1.5ft @ 13s from 307° (WNW)

1.8ft @ 13s from 311° (NW)

Kaneohe Bay
6ft @ 7s from 65° (ENE)

Small NW energy is at the upstream buoys and also in our waters. Windswell is going up too, home guess for Hookipa is around chest to possibly head high. Oh, if you're wondering where the NW energy comes from, below are the maps of Sept 13 through 16 that show the small fetch. Much more solid is the one that was later provided by the low that appears in the last picture. You can see in the Pacioos forecast below that the related swell is predicted to peak Tuesday night.
