Saturday 5 1 21 morning call

No photos from yesterday, here's a random shot from the island of Guersney.

3am Surfline significant buoy readings and discussion.
South shore

1ft @ 13s from 204° (SSW)

Tasman Sea swell trickling down. Check the Lahaina or Kihei webcams if interested, for size, conditions and consistency.

North shore
6.1ft @ 16s from 305° (WNW)


4.8ft @ 17s from 310° (WNW)
2.2ft @ 10s from 343° (NNW)
1.7ft @ 12s from 347° (NNW)
1.6ft @ 11s from 344° (NNW)


4.5ft @ 6s from 57° (ENE)
3ft @ 16s from 310° (WNW)
2.9ft @ 11s from 340° (NNW)
2.7ft @ 9s from 350° (N)

New long period WNW swell on the rise. It went up to 7ft 17s at the NW buoys, but I'm afraid it's going to be max 5ft locally. The shorter period NNW one will be disappearing throughout the day instead.
Below are the maps of April 27 through 30 that shows the fetch that generated the long period swell (red arrow). It should provide waves until Wednesday.

Below are the graphs of NW001 and Pauwela together with the Surfline forecast.

Home guess for Hookipa is around head and a half. Could get up to double during the day. Not a good direction for Honolua, even though, thanks to the long period, some of the more northerly sets could make the wrap around Molokai and very inconsistently get there (very low confidence on that). Strong easterly trades.
