Tuesday 7 11 17 morning call

Been busy sharing some gorgeousness with my paddling students the last couple of mornings. Windfoiling filled up the afternoons.

4am significant buoy readings
South shore

1.7ft @ 13s from 138° (SE)
1.6ft @ 11s from 138° (SE)

2.8ft @ 12s from 150° (SE)

2.2ft @ 13s from 162° (SSE)

I didn't go Lahaina side the last couple of days, but I did check the webcam. It seemed like there was only a decent day in this swell and that was Sunday. Remember that graph of the Samoa buoy I posted showing solid 6f 14s for 3 days in a row? That's how much the waves lose in a 4 days long journey. Also remember the position of the originating fetch? Pretty much south of us. Most likely the size and direction of this swell was a combo that got blocked a lot by Kahoolawe.

Anyway, SW and SE buoys still show more than 2 feet out there and Lahaina town, as usual, has clean conditions, waist to occasionally even head high waves that that guys is scoring by himself (for the moment). I will go that way too, but I'm taking it easy this morning. I had a long windfoiling session yesterday and those always beat me up. Stay tuned for a beach report later.

North shore
2.8ft @ 7s from 79° (ENE)


Wind map at noon.

North Pacific shows two fetches of similar intensity of around 20-25 knots. The stronger the wind (and the bigger and long lasting the fetch), the higher the period of the resulting waves, but, as Pat Caldwell reminds us the shorter the wave periods, the more the swell loses size with travel distance. That means that we will only see something from the trades windswell and nothing from the distant NW fetch.

Couple of fetches also down south, also far from ideal. The strongest part of the closer fetch is oriented towards central America and hopefully we'll get some angular spreading. Uncle Pat agrees and informs us that the highest seas are aimed SE of Hawaii. Wave watch iii brings in 7 feet at 13 seconds from 200 degrees at american samoa late Tuesday. Only a low swell is due locally from 190-210 degrees, with low odds since it was not directly aimed at Hawaii. It could bring breakers back to heights similar to Monday 7/10.

And another stunning day is on its way.

You think tropical storm Eugene will bring us something? I guess we have to hope for it to intensify...

I don' think we'll get much. More than the intensity, it's the track that the storms have and this one is not favorable.
