Friday 4 5 19 morning call

The funding campaign for the new Lahaina harbor webcam has raised $1205. Thanks a lot and let's keep them coming. I'm gonna start my posts with an update like this until it reaches its goal of $2,000. Please donate to the page, not to me. I have nothing to do with this campaign, other than the fact that I totally support the cause.

Intense day of action for the windsurfers at Hookipa. This is blog reader Geoff in my pick of the day's gallery by Jimmie Hepp. He was the one that gave me the idea of the wind meter (and contributed to the cost of it). The new roof is up, I just have to find the time to put it back up. I had it yesterday, but it was blowing way too hard to get up there.

These are a couple of awesome shots of the shore break at Makena, kindly sent by blog reader James Dawson. Hard to tell the size (probably small), but beautiful colors and reflections.

3am significant buoy readings
South shore
2ft @ 9s from 168° (SSE)
1.9ft @ 8s from 154° (SSE)
1.2ft @ 14s from 223° (SW)
1ft @ 11s from 209° (SSW)
All those small energies at the Lanai buoy should make for another small, possibly tiny, but not flat day on the south shore. Yesterday it was up to knee high.

North shore
5.2ft @ 14s from 306° (WNW)
3.7ft @ 10s from 312° (NW)
4ft @ 14s from 326° (NW)
3.1ft @ 9s from 350° (N)
2ft @ 11s from 332° (NNW)
2.6ft @ 10s from 326° (NW)
2.6ft @ 14s from 322° (NW)
3.5ft @ 10s from 342° (NNW)
2.6ft @ 15s from 328° (NW)
2.3ft @ 6s from 61° (ENE)
Pretty modest numbers at the buoys, but that's pretty much what the Surfline forecast was calling for (3ft 15s at 6am). Yesterday at sunset Pauwela was reading just 1ft 18s and there were some overhead sets at Hookipa... the superior shoaling power of the long period. Hopefully it will still be in that range, I'll report at first light.

Below is the graphs of NW and Pauwela, together with the Surfline forecast. I circled in red the lines of the current swell, it should come up a bit during the day, and then tomorrow another bigger pulse (5.5ft 16s) and excellent surfing conditions with no wind all day.
If you're interested in the genesis of this swell, here's Pat Caldwell's description of the history of the fetch:
A new storm-force low pressure system unfolded 3/31-4/1 west of the Date Line with seas growing to near 30 feet in an area 2000 nm away. The system occluded 4/1-2 as the surface winds weakened, the fetch area widened, and the center drifted slowly north near 170E. It is expected to hold with gales into early Friday, making for a long- lived event within 305-325 degrees.
A new low pressure was spawned 4/2 near the Date Line with a fast track ENE into 4/3. The center dropped to near 960 mb 4/3 as it became hurricane-force well NNW of Hawaii. Models show it east of the Hawaii swell window on 4/4. It should make for a short-lived event.
Below is the collage of the maps of March 31, April 1, 2, 3 and 4.
Wind map at noon.
Should be no wind till 9 at Hookipa and specially down the coast.
North Pacific continues to offer a NW fetch, pretty wide, but not very intense. Still plenty waves ahead.
Nothing from the south.
Morning sky.
