North Pacific swell poses the question: Will Eddie go?

Swellnet Analysis

When Jaws on Maui broke in early October hopes were high for a stellar Hawaiian season. Since that session, however, there's only been a couple of notable swell events none of which approached the size or intensity of that early season swell.

Well, the big wave drought is about to break as an oversized west-northwest groundswell bears down on the Hawaiian Islands.

The source of this swell is a 'bombing' low pressure system off the Japanese coast ('bombing' is a term used when the central surface pressure drops by more than 24hPa in a 24 hour period). Wind speeds around the core of the low have already been clocked at 60kts by satellites, but a further intensification today should result in winds reaching hurricane force, or 70-75kts. While wind strengths within the severe storm are phenomenal for a cold core (non tropical) system, it's the east-northeast movement towards Hawaii while retaining its intensity that will generate this oversized groundswell.

Will this be the swell to kick the Eddie Aikau Quiksilver Big Wave Invitational into gear after a three year hiatus? This question can be answered in two parts, the first relating to the swell size and direction, while the second revolves around the local winds and conditions.

The perfect swell direction for Waimea Bay under a long-period groundswell is from the west-northwest. When long-period swells arrive from this direction, their size isn't affected by the deep water reefs of Outer Log Cabins to the north. Additionally, swells with too much west will fall within the wave shadow of Kauai.

The direction of this swell is ideal, however the size may just fall on the wrong side of the required 20 foot+ to get the Eddie underway. Veteran North Shore surfers have a rule of thumb that storms have to push east of the International Date Line to produce a genuine 25-20 foot swell and the storm will fall just short of this, stalling some 1,000km to the west of the date line. In saying this the sheer strength of the wind and magnitude of the low should, by our estimates, still produce a 20 foot+ groundswell for Friday Hawaii time (Saturday Australian time).

The other issue that organisers of the Eddie will be watching closely are the local winds. At this stage they're expected to be cross-shore from the north-northeast as a frontal system extends across the Hawaiian Islands. Some Waimea Bay surfers prefer the wind to be light onshore as it provides small chops and bumps they can use to project themselves into the waves earlier than normal. This only works up to a point, if the onshore wind gets too strong the wave at Waimea simply loses its shape. The cut off point is around 15-20 knots, which is the predicted wind strength for Friday.

With the storm and local winds not likely to change much over the next couple of days the job of assessing the conditions and making the call now falls squarely onto the organisers of the Eddie Aikau. Stay tuned for further details. //CRAIG BROKENSHA

I just heard from someone involved in the Eddie, apparently George Downing and Glen Moncata (co-directors) will be making a decision tomorrow. As per Craig's article they've got a weather eye on the local winds.

Yep, trying to find out what the go is with that. Potentially the Eddie, the Red Bull Peahi event, the Nelscott Reef Challenge and the Mavs comp could all run in this swell event. Reckon there'd be a few big wave surfers keenly watching this swell and winging some last minute flights.

Wave Watch III forecasts have 28.3 second forerunners arriving Thursday morning Hawaii time.. 28.3s!

This gives a great representation of how phenomenal the storm is, as periods of this length can only be made by hurricane force winds.

Thanks Craig. Stu, did they say why the Eddie is off? I wouldn't think a swell like this one in the North Pac comes off very often, so it seems strange they're not running the Eddie? Is it local winds?

Also, Craig, how does one make sense of the files on this page and determine the location without going through every file? Is there a similar plot file for any locations near the east coast of Aus?

I don't look at those charts sorry Don, but it looks like the file name gives the location, with hs signifying significant wave height, and tp being peak period, while the numbers are the forecast hour.

There's no East Coast charts, just a regional Australian chart under the name aus_ind....

And regarding point locations near the East Coast, there are none publicly accesible but we will have data available with the new website.

With an 80% chance that the Mavericks Invitational 2012/2013 presented by GoPro will run this Sunday, January 20th, John Forse, Founder and Contest Director of the Nelscott Reef Big Wave Classic issued this statement.

"As much as we hate to pass on a good swell, We have decided in the interest of cohesiveness of the big wave brotherhood and the Big Wave World Tour to not run the Nelscott Reef Big Wave Classic this weekend and throw all our support behind the Mavericks Invitational that should have great waves for the best big wave surfers in the world. We still have 2+ more months in the waiting period and hope the surf gods will reward us with our own epic swell."

Latest news: The green light is shining bright - the Mavericks Invitational Contest, presented by GoPro, is on! A more than "24 hour" notice has been called and contestants and alternates from Brazil, Hawaii, Southern California and South Africa are making travel arrangements. Veterans from Santa Cruz, San Francisco and Pacifica will make the drive with hearts pounding.

Everyone involved, and then some, have been following the swell charts since last Thursday, waiting to see if the predicted heights and durations would drop but the maps have held their own and now this beast of a wave will be paddled into for a money prize on Sunday, January 20. The guys invited have been surfing and watching footage of the infamous wave for decades. This is no ASP dream tour, Mavericks is one the gnarliest waves in the world.

Mark Sponsler, the official swell forecaster for the contest predicts, "A strong storm producing 60 foot seas. A solid, very long period swell." Light to moderate offshore winds combined with a low tide at 12:32 p.m. will make for favorable conditions at this years event.

Theres no swell forecast on the website - they are saying big and beautiful so in reality 12 - 15 feet with bigger sets?

If I have it correct does that mean a 3am start (Aust Est std time)

Does anyone know the format - got 24 surfers again the web says very little.

Pulled this off another site. Quote from oraniser Jeff Clark. Nothing about size!!!??

"We watched this thing form in the center of the storm-generating West Pacific for days," Clark said. "And after all the models, a few things are clear. We are gonna have really good weather. We are going to have a solid powerful swell that's gonna hit Saturday with super long interval (20+ seconds) and hold through Sunday."

25 second peak periods were registered on the NDBC 51201 buoy which is situated about 6km offshore from Waimea late this afternoon Hawaiian time.

http://www.ndbc.noaa.gov/station_page.php?station=51201

Currently the open ocean swell is around 2.5m's @ 22 seconds and climbing, while the 51101 buoy which is 500km's NW of Oahu is at around 4.7m @ 19 seconds and still climbing.

Don, I'm pretty sure they mentioned that the local winds weren't favourable.

thermalben's picture
thermalben's picture
thermalben Saturday, 19 Jan 2013 at 9:45am

Don, as F21 said local winds were expected to be an issue today (AWS obs suggested it was calm at dawn, and that the N'ly kicked up around lunch, surfcam obs suggest it might be 15-18kts now).

I'm not sure where their size thresholds are but looking at the 51101 buoy, it appears to be a fraction smaller than when I was there two years ago (and they called it off for being too inconsistent).

I've also been watching the Waimea surfcam for some time and haven't seen any waves breaking yet although there is a pack of surfers in the lineup, and it can be a half hour or more between waves at times, which is hard to pick up on a surfcam.

Anyway, I'll get some feedback on size later today from people on the ground and will let you know how big it was.

thermalben's picture
thermalben's picture
thermalben Saturday, 19 Jan 2013 at 5:15pm

RCJ reckons there were only a couple of 15ft+ sets at Waimea today. Said he saw a few 25ft sets at Backyards in the arvo, however a few crew went out at Himalayas after seeing some bombs only to find it was mainly 10ft or so. And the wind came up around half past ten making things bumpy. So overall a pretty average event for the North Shore.

Will be very interested to see how big Mavs ends up getting - our internal models show around 15ft or so for Sunday (local time). I've also noticed that so far, none of the event officials or forecasters are willing to put a size on it (at least publicly anyway). And, it'll be much more inconsistent there compared to the North Shore. However local bathymetrical effects - which I'm not familiar with - may assist in kicking up the size a little more. We'll have to wait and see.

Looks like a great day for surfing though on West Coast USA. 8 foot clean. Red Bull struggling too on the webcast. Without promoting another site Surfline have a reliable feed.

Without knowing the break guessing Nelscott will be similar in size 3-4 times overhead.

WHole event is a great gopro commercial

The Mavericks Invitational is supposed to be a BIG WAVE event? So why are they doing the Huntington Hop and pulling into the inside ledge. Whoever called the comp on needs to wear the dunce cap for the rest of the week.

From Swellnet article above, "Veteran North Shore surfers have a rule of thumb that storms have to push east of the International Date Line to produce a genuine 25-20 foot swell"

This swell had to travel another 2,000+ miles to reach the US mainland, dealing with swell decay and crossing the continental shelf in the process. Hindcasting it from my gilded and gifted position the swell was always going to struggle to reach 15 foot. Which is exactly what happened. A huge letdown.

Yep, it was hugely underwhelming, eh? Glad I didn't get up early to watch it. I often wonder how the surfers feel in these circumstances, some of them, such as Twiggy Baker, Frank Solomon and Chris Bertish, flew all the way from South Africa on last minute flights. Would they be angry, thinking the whole thing was a waste of time (I mean really, it didn't even get close to being a legit big wave comp) or are they just happy to have had a shot at the first prize cheque?

It'll be interesting to hear how big Nelscott Reef and other west coast spots got to see if it was distance from the source that caused the diminutive size or something else (local bathymetry near Mavs, for instance).

After the poor internet coverage at Mavs be interesting how things turn out for Jaws contest hosted by Redbull. In the article below it mentions TV airtime on NBC.

http://www.actionrecon.com/full-details-for-red-bull-jaws-invitational/2...

Kelly is on the invite list too - does that mean he can't compete or does he have a ASP waiver?

Also Snips Parson broke his back in San Fran same day as Mavs Invitational ran and is contest director.

Few spanners there, be some pressure to run event with NBC coverage wouldn't there.

If I heard right layday at Volcom Pipe Pro because conditions are too gnarly - what is going on??
