Big Picture

BIG PICTURE Sunday 9.18.16

All NW shores have become dominant but let’s not to ignore the Taz -East Coast of NZ sources. After a long period of fun swell for town and country we just see 2 small NW’s and one moderate SSW for the rest of the month.

NPAC
The Jet is decently consolidated thru the next 7 day outlook but no significant NW ground swells form within it.
This last NW did reach 8’ (triple overhead) for top spot moments Saturday. The creator storm crept East off Kamchatka last Monday with its center tracking along the Aleutians and long wide fetch off its SW flank. The fetch is a nice direct hit Monday-Wednesday. We claimed 5-7’ NW peaking Saturday with the event filling Friday afternoon to 3-5’ with 18 sec forerunners.
An area of weak 30kt winds up near Kamchatka Sunday-Monday pointed mostly ESE so not a good fetch. We’ll see a 12 sec 1-3’ NW around Friday the 23rd with some more of the same into the weekend.
Then it’s lame until we ‘may’ see a small 3’ NW Friday the last day of the month. Well below seasonal.


SPAC

We’ve been doing above fall season sizes with back to back SW to SSW swells reaching well overhead at top moments. We’re at chest high today.
Next in line is a whopper winter low moving east from under NZL near the Ross Ice Shelf from Tuesday the 13th. The issue is the storms zonal or west to east track. Thanks to swell dispersion (angular spreading) of its broad area nearing 30’ seas we’ll should see some fun 2-4’ SSW surf by Wednesday the 21st. Forerunners will be 18 sec by 2pmTuesday with lully 3’ surf. (Southern Chile will hit 12-18’ easy by the 20th due to the captured fetch and storm track). Surf for us will slowly decline Thursday but still be 4’ and Friday 3’ etc.
We go into a slow pattern for the rest of Sept. after the above swell due to a zonal Jet near the Antarctic Ice sheet.

Tropics and Trade Swell

Trade swells have been average 2-3’ with average trade speed variation between moderate to strong. Last Friday surf ramped to 4’ due to the High NE of us pushing on the Low pressures to our SE-SW. This increases the pressure gradient in between the High and Low; thus the upstream trade swell & longer 9 sec periods. This swell eases up this week to 1-2’+ and holds.

Former Hurricane #15 (Orlene) luckily weakened and tracked N and stayed away for the Islands. We’ll only see average surf now along windward this Wed-Friday. (First models fantasized 8’ surf, thus proving the possible variations with such tropical systems). The season isn’t over technically till Nov 30th. Again, it could stop before or after pending the boss’s orders: Mother Nature.
