4 19 17 morning call

Just one surf session in Lahaina is all my jet legged body allowed me to do yesterday, but it sure was fun.
If you thought you saw a t-rex surfing yesterday at Grandma's, I've got good news for you: you did not go insane, there really was one.

5am significant buoy readings
South shore

2.9ft @ 17s from 197° (SSW)
1.9ft @ 13s from 198° (SSW)
As forecasted, the south swell picked up a notch, but as forecasted, the wind is from the south this morning and it's quite blown out over there. Check the webcam to see yourself.

North shore
8.8ft @ 9s from 346° (NNW)
8.3ft @ 9s from 320° (NW)

5.9ft @ 8s from 329° (NW)           
3.5ft @ 6s from 342° (NNW)
2.3ft @ 4s from 346° (NNW)
4.1ft @ 9s from 62° (ENE)

Short period NW energy at all buoys but Pauwela. I explain that with the position of the very close front that is generating that energy. As you can see from the current wind map below, the associated fetch is just west of us and it's main energy is missing us to the west. As the westernmost island of the chain, Hanalei is consequently getting the biggest readings, with Waimea right behind.
Surfline calls for an increase locally in the afternoon (6f 8s), but the low pressure is not modeled to move any east, so I kind of question that a bit. And even if it happens, it's gonna be onshore.
In fact, even if at the moment (6.30am) the wind is blowing from the south, later on today it will be blowing from the north. The closeup wind map below is a 2pm and there might actually be quite a long transition time in which the wind will unfortunately be onshore both on the south and north shore. Tough to find clean waves today.
The MC2km maps would help a lot in that task, but they are stuck at March 31. Please let me know if any of you guys has found the reason (sometimes they just change the url).
Current wind map shows the fetch I just talked about and a windswell one. The elongated south one has pretty marginal winds.

The local low is fabricating plenty clouds (the animation is pretty cool, link n.6).

Which will bring plenty rain.
