Sunday 4 18 21 morning call

No photos from yesterday. This was posted by Garret McNamara with the caption:"Imagine getting caught inside by this one"... Obviously Nazare, photo by Hugo Silva.

5am Surfline significant buoy readings and discussion.
South shore

1.4ft @ 11s from 230° (SW)
1.3ft @ 9s from 215° (SW)
1.1ft @ 18s from 206° (SSW)


1.3ft @ 18s from 201° (SSW)
1ft @ 9s from 206° (SSW)
1ft @ 12s from 194° (SSW)
0.8ft @ 14s from 185° (S)

As I suspected when I posted the source fetch maps, this Tasman swell is staying at very low levels. Check the Lahaina or Kihei webcams if interested, for size, conditions and consistency.

North shore
6.1ft @ 9s from 333° (NNW)

7.2ft @ 9s from 350° (N)

4.1ft @ 9s from 359° (N)


3.2ft @ 11s from 348° (NNW)
2.8ft @ 10s from 343° (NNW)
2ft @ 6s from 24° (NNE)

Relatively short period NNW energy continues at the buoys. Home guess for Hookipa is around head high and relatively clean conditions, even though I feel a bit of trades flow.

We might get more perfect morning glass again starting tomorrow, based on this outlook from this NOAA page:
Moderate to fresh northeast to east trade winds will persist into tonight, then shift out of the southeast and diminish through the first half of the week as a weakness in the ridge develops to the north. This pattern shift will translate to a land and sea breeze regime developing along the coasts for most areas beginning early Monday.
