Big Picture

BIG PICTURE Update Saturday 4/22/17

NPAC

Thanks to the recent decent (elongated, consolidated) Jet stream off Japan to near our latitude…. we’ve been above seasonal averages esp Friday’s 12’+ NW. By Thursday there’s a dip near the dateline with a big split Saturday the 29th and a large High to our east. Thus the long haul hints of a quiet period esp. April 1st-4th.

#1 Recent: Friday’s whopper came from a Low moving off the Kurils Monday the 17th. It occluded/stalled somewhat last Wednesday or so and enabled a partial captured fetch. These factors also created a super long fetch and longer lasting episode. The surf was well above Advsry Levels peaking at just over 12’ Friday and lasted at 8’ Saturday AM. The direction favored NNW and will end up North Sunday at 5’ or so for focal spots.

#2 Next: Monday 4/24 we may see a 2-3+’ WNW at 12 sec. from a broad but weak Low off Japan last Wed-Thurs. 19-20th.

#3 Up next is Wednesday’s 12 second with NW surf at 2-4’ from the same system above. “Gale” ended up spinning up near the Aleutians thru this current weekend.

#4, Last we need to wait and see about the strange area of low pressure on the models Friday the 28th. If anything it will be short period background swell to keep country from going flat.

SPAC

The Jet has fattened up and empowered a good run of SSW swells. We’ve already had 3 for spring and there’s at least 2 more coming (next being Late Thursday into Saturday the 29th. This active pattern started just after mid-month.

#1 Recent: A 45-55kt Low South of Tahiti last Thursday the 13th thru Sat. got here a week later peaking at just over 3’ and lasted a few days. It’s 2.5’ Saturday. The energy veers SSE.

#2 There’s been a long run of fetch to our SSE from the previous system as it tracked east. We should see some near 3’ SSE surf at 11 sec later Sunday into Monday.

#3 A gale coming up the East coast of NZL (at least it’s fetch) last Wed-Thurs may bring us a near 2’ deep water 16 sec SSW later Thursday into Friday and will be overwhelmed by the next event.

#4 Last: A much more powerful ENE tracking storm is on the models Thursday with 45-55kt or storm force pockets of gales Thursday the 20th. Let’s look for 18 sec forerunners toward midnight Thursday the 20th with 16 sec SSW surf rising all day Friday to easily 3’ and then with 15 sec surf mostly peaking 2- 4’ Saturday.


Trade swells have been minimal at 2’ or less for a while with all other shores stealing the show. Trade swell ramped a hair to 2.5’ this weekend and should see better ramp Wed-Friday to hopefully 3’ but that’s it. Local trade will be light all this week so the increase is from upstream winds as the current high moves east.

So far nothing on the forecast for Hawaii for the next week.
