Change Coming to North Pacific
Fall Moves In, But Summer Won't Let Go of S. Pacific Just Yet


New Swell Classification Guidelines (Winter)

Significant: Winter - Swell 8 ft @ 14 secs or greater (11+ ft faces) for 8+ hours (greater than double overhead). Summer - Head high or better.
Advanced: Winter - Swell and period combination capable of generating faces 1.5 times overhead to double overhead (7-10 ft) Summer - Chest to head high.
Intermediate: Winter - Swell and period combination generating faces at head high to 1.5 times overhead (4-7 ft). Summer - Waist to chest high.
Impulse/Windswell: Winter - Swell and period combination generating faces up to head high (1-4 ft) or anything with a period less than 11 secs. Summer - up to waist high swell. Also called 'Background' swell.

On Thursday (10/8) North and Central California had modest local generated northwest windswell at waist to chest high with light northwest winds and a bit of texture and lump on it. Southern California had thigh high northwest windswell up north and heavily textured. Southern hemi swell was still waist to almost chest high on the set down south with lighter texture. Hawaii's North Shore continued getting limited northwest windswell in the head high range with a few bigger sets and glassy conditions. The East Shore had waist to chest high east windswell and chopped. The South Shore had some thigh high background southern hemi background swell with waves thigh high and clean.   

The forecast for North and Central CA is for fading local windswell on Friday, coming back up some to chest high on Saturday then fading on Sunday. Not particularly inspirational. Southern California is to drop to effectively the flat zone on Friday and stay there through the weekend, though some degree of very limited northwest windswell might continue sneaking in up north to thigh high on Fri and Sat.  The North Shore of Hawaii is to see fading northwest windswell at waist high or so on Friday, then new energy start moving in from the Western Gulf on Saturday at 1 ft overhead and to 2 ft overhead on Sunday. This windswell to fade some after that, but not out by any means. The East Shore is pretty much out of the picture from hear on, with the North Shore taking presedence.  The South Shore is to not see anything really rideable until Saturday, and then only thigh to waist high , fading out on Sunday with nothing to follow.  

Longterm the Active Phase of the MJO continues forecast to have more influence.  First up is a gale scheduled for in the Western Gulf  Thurs/Fri generating 16 ft seas off it's back-end providing more windswell for Hawaii into early next week. And the front end of this gale is to generate up to 25 ft seas aimed a bit east on Saturday targeting Central Ca up mainly into the Pacific Northwest and Canada.  Maybe some energy from Monday off this if it develops. The extratropical remnants of Typhoon Melor are still forecast to push east from the Kurils to the dateline Fri-Sat (10/10) with 32-35 ft seas, but fading before ever reaching the dateline. Some long distance longer period small scale swell could result for Hawaii mid-next week and later in the week for the US West Coast. And interestingly the remnants of that system are to reorganize off Central CA early Mon/Tues (10/13)  generating 25 ft seas close to shore, with a vigorous front forecast pushing onshore about as the swell from this systems arrives in CA. A washout likely up north, but Southern CA might get a break. 


Current marine weather and wave analysis.cgius forecast conditions for the next 72 hours

North Pacific

On Thursday (10/6) the North Pacific jetstream was pushing hard off the Kuril Islands falling into a developing trough that was centered from the dateline to a point 1200 nmiles north of the Hawaiian Islands with up to 170 kt winds pushing into it.  Not too bad, but this trough was about maxed out.  A solid ridge was holding tight off the US West Coast, but slowly loosing ground to the building low pressure pattern over the greater Pacific. Decent support for gale development is suggested in the dateline trough. Over the next 72 hrs that trough is to get pinched off and effectively gone on Saturday, though decent wind energy is to continue streaming off Japan at 150 kts, ridging some over the dateline. That energy is to track east and form yet another trough in the Gulf of Alaska on Monday with winds still 150 kts pushing right over the San Francisco area on Tuesday, likely providing another early taste of winter to the region. That trough is to push inland with a far weaker trough forecast developing in the Gulf of Thursday with 120 kt winds. But more winds energy is queued up behind it.  At this point it looks like the real start of Fall is to begin in earnest for the north Pacific, aided by the Active Phase of the MJO and pushed more by a developing El Nino pattern. 

At the surface on Thursday (10/9) high pressure at 1028 mbs was trying to hold on centered just off the Washington Coast, while a broad but weak gale was taking over the dateline and Western Gulf regions. Northwest winds were being generated at 25-30 kts targeting Hawaii almost directly with 17 ft seas being generated and pushing southeast, with some degree of 11 sec period windswell likely in the days ahead. The US West Coast to see little of this tough.  Over the next 72 hours this same basic pattern is to hold with a mini gale forming on the eastern edge of the mother gale in the Western Gulf, hammering away at the high off the Canadian coast. 40 kt west winds are forecast over a small area at 38N 160W on Thursday evening building to 55 kts are 42N 155W aimed due east (towards NCal up the 294 degree path and 1500 nmiles away) then racing towards Alaska by evening.  The issue is these winds are to get very little time to get traction on the oceans surface as they race north.  Still 25 ft seas are forecast on Friday AM (10/9) at 42N 154W and holding at 44N 152W in the evening.  Perhaps some form of small 16 sec period swell to push into the Central CA coast late Sunday (10/11), but that is really just a wild guess. 

At the same time the remnants of Typhoon Melor are forecast to start tracking east off northern Japan on Friday AM (10/9) with 55 kt winds forecast at 42N  150E aimed generally east up the 304 degree path to NCal and 305 degree path to Hawaii. 34 ft seas forecast at 42N 153E.  In the evening winds are to be down to the 40-45 kts range at 42N 158W generating 36 ft seas at 43N 158E.  These are to be on the 302 degree path to NCal and 2900 nmiles away and the 310 degree path to Hawaii and 2500 nmiles away. By Sat AM (10/10) winds to be down to 35 kts at 43N 165E with seas fading from 32 ft at 43N 165E, not even reaching the dateline.    This one is to be gone after that with only 29 ft seas left Sat PM at 44N 170E. If this.cgiays out as forecast some degree of funsized 15-16 sec period swell is likely for the Hawaiian Islands on Tues (10/13) with less for the US Mainland on Thurs (10/15).

California Nearshore Forecast
On Thursday (10/8) high pressure at 1028 mbs was off British Columbia and ridging into the Northern Canadian coast, trying to hold developing low pressure in the Western Gulf at bay.  A weak 15-20 kt northern flow was continuing just off Cape Mendocino with light winds (10 kt or less) south of there. The north fetch is to push a little further south on Friday to just off Pt Arena and up to 25 kts, but still pushed away from the coast resulting in reasonably favorable sea conditions.  By Saturday (10/10) the fetch is to start dying and gone by Sunday with near calm winds forecast from Pt Arena southward.  But a broad local gale is forecast building off the coast, with the front hitting Monday AM (10/12) and south winds at 20+ kts in effect from near Pismo Beach northward and building, with rain hitting late afternoon. South winds are to be reaching down to Pt Conception late Monday at near 25 kts and rain by Tuesday AM. A real mess of a storm is forecast through Tuesday evening, finally relenting through the day Wednesday. Light winds forecast mid-Wednesday over the state into Thursday (10/15). 


The Inactive Phase of the MJO is fading over the Eastern Pacific, expected to continue suppress development there through 10/12 or so.  But a favorable Active Phase pattern is influence the West Pacific as evidenced below:

Typhoon Melor was positioned off the northern coast of Japan accelerating off to the northeast bound for the dateline while turning extratropical.  See details above. 

Tropical Depression Parma which had been inland over the Northern Philippines is moving west into the South China Sea, expected to continue west eventually pushing over Vietnam early next week. No swell producing fetch is forecast in the North Pacific.

Tropical Depression #21 was just northwest of Saipan tracking due north with winds 30 kts, expected to reach minimal tropical storm status before turning northeast and turning extratropical on Sunday (10/11). Limited support for producing swell in the North Pacific.    

With the building Active Phase, we believe the odds for yet more tropical development in the West Pacific is good over then next 3 weeks, with some perhaps having the potential to curve north and northeast while turning extratropical.  


South Pacific

At the surface on Thursday (10/8) high pressure at 1028 mbs remained in control of the northern reaches of the Southeast Pacific pushing to the south to 50S,  not as bad as a few days earlier but still not good. A persistent zonal flow (west to east) was occurring south of the high pushing most surface winds tot he southeast (Antarctica). Over the next 72 hours the models suggest a gale low is to quickly build under New Zealand starting late Friday (10/9) with 45 kt southwest winds at 59S 163E producing 30 ft seas at 60S 160E, barely off the northern edge of the Ross ice Shelf. By Saturday AM (10/10) 40 kt southwest winds are forecast at 55S 178E pushing east-northeast resulting in a solid sized area of 36 ft seas at 54S 175E pushing up to 38 ft in the evening at 53S 175W. A quick fade is forecast Sunday AM (10/11) as the fetch dissipates. This forecast still seems a bit of a reach, but it has been on the charts for like 5+ days, so something is possible. And the fetch/seas are forecast to be almost entirely unshadowed by Tahiti relative to the US West coast. Assuming it does develop, a good shot of moderate period southern hemi swell (15-16 secs) seems likely for Tahiti, Hawaii and the US West Coast in the days beyond.  Will monitor.

Marine weather and forecast conditions 3-10 days into the future

North Pacific

Beyond 72 hours the remnants of ET Melor are to race east over the dateline Sunday with seas fading below 20 ft, then starting to regenerate aided by an improving jetstream flow aloft. A broad fetch of 30-35 kt northwest wind are forecast at 40N 150W off the Central CA coast on Monday AM (10/12) generating 20 ft seas there, holding while dropping southeast more in the evening with a front pushing into the entire Central coast then. 25 ft seas are forecast at 40N 148W (285 degrees relative to San Francisco and 293 degrees relative to SCal). The fetch is to push even closer on Tuesday AM with a solid front impacting the coast down to Pt Conception and seas holding at 25-26 ft at 38N 140W on the 280 degree path to SCal. This is good news for this region if it develops. Still 35 kt west wind are forecast off Cape Mendo in the evening with 24 ft seas off San Francisco. The whole mess is to be moving onshore and dissipating early Wednesday with residual swell holding into the mid-day. And early taste of winter if this occurs as forecast with Southern CA the best candidate for rideable swell. 

Things to settle down after that with no swell producing weather systems forecast, at least for a few days.

MJO/ENSO Update (reference): As of Thursday (10/8) the Madden Julian Oscillation (MJO) was moving into the Active Phase. The ENSO (El Nino Southern Oscillation) index was retreating from positive territory. The Daily SOI index was at -4.45. The 30 day average was down to 2.46 and the 90 average was steady at 0.08, dead neutral.  The SOI index is likely heading down for the days ahead driven by the Active Phase of the MJO.

Wind anomalies at the 850 mb level (approx 5000 ft up) as defined by models indicated a weak and fast fading area of easterly anomalies in control of the Eastern equatorial Pacific from just east of the dateline into and over Central America. This area is expected to slowly subside and be effectively gone by 10/15,a week from today. The models also indicate that western anomalies associated with a building Active Phase of the MJO remained present in the Indian Ocean extending from just west of Eastern Africa over the width of the Indian Ocean and starting to limp into the far Western Pacific, but down yet again from the strength projected at our last update a few days ago. The Active Phase is expected to make slow steady progress into the West Pacific but now not forecast to even make it to the dateline, holding north of New Guinea through 10/17 then fading into 10/22 turning dead neutral after that through 10/27. This is typical of the models, to dow.cgiay the length of the episode, only to readjust and extend it's reign mid-way through it's lifecycle. Regardless, mid-to-late October still looks like a good window for support of North Pacific Storm development, moving slowly from the West Pacific tropics towards the Central Pacific (Hawaii and the Western Gulf of Alaska) .

Sea Surface Temp anomaly data (10/1) indicates only subtle change over the past month, with a solid area of warmer than normal water extending over the equator starting on the dateline and building east into Central/South America with temps holding at 2.0-3.0 deg C above normal in the east. This is suggestive of a weak to moderate El Nino.  The expanse of the warmer waters continues to built north of the equator, solidifying it's grip up the coast of Mexico and Baja but retreating from Southern and Northern CA, and extending west almost to Hawaii then southwest to the dateline. Effectively there is a broad wide triangle of warmer than normal  water extending from just south of San Diego southwest just under Hawaii and on to the intersection of the equator and the dateline, then tracking southeast on to Northern Peru.  This is not historically anything exceptional, but clearly a moderate El Nino just the same. in reviewing surface water temp anomalies over the past decade and more, this is in no way similar to the monumental ENSO event of 97/98.  but as previously stated, it still surpasses and event since then (over the last 12 years) in terms of either water temps or areal coverage. And the warm pool is holding if not subtly building in areal coverage, though not building in intensity. Cooler than normal waters we had been monitoring off Africa have totally faded out.

Below the surface on the equator things continue to look most positive. A steady flow of warmer than normal subsurface water continues tracking from the West Pacific (150 m below the surface) under the dateline and breaking the surface near Central America as it has for months now.  The Kelvin Wave we had been tracking over the past months has finally reached Central America with the core moving into the coast. Residual 1-2 degree above water temps were fading at 110W, but most energy had moved off the charts. This Kelvin Wave was the result of a Westerly Wind Burst (WWB) in the West Pacific that occurred on 7/25-8/2.  We expect to see surface water temperatures jump up in early Oct off Central America, feeding the developing warm water pool there and fueling El Nino as this Kelvin wave impacts the coast. The good news is that another core of 2 deg warm water that first appeared under the dateline on 9/17 moving east to 175W by 9/22 and 172W on 9/24, has now has built to 3 degrees above normal (9/29) and still holding as of 10/8 at 175W.  This is a new  Kelvin Wave, one we've been looking for and is associated with a persistent weak westerly surface wind flow that had been in.cgiace west of the dateline from 9/8-9/17. It is embedded in a continuous stream of 1+ degree warmer than normal water extending from 155E under the dateline and into the existing warm pool off Ecuador.  This one is expected to reach the coast of Ecuador late December, about at the peak of whatever El Nino will be in.cgiace for this winter. So all looks good for maintaining the existing warm pool for a while if not building it.  But for more than a weak El Nino to form, we need more warm water over the long haul.  

On 10/1 a solid patch of westward winds were depicted in-control of the West Pacific with strong west anomalies extending to almost the dateline. This had been in.cgiay since 9/27 and was associated with tropical systems Parma and Melor. This is good news. A full on Westerly Wind Burst was in effect. As of 10/3 fully blowing west winds were subsiding, though westerly anomalies continued reaching to the dateline.  And by 10/6 just light west winds were in effect west of the dateline.  But then again on 107 another group of fully blowing west winds were depicted extending all the way to the dateline, with decent force too. Anomalies were in full effect to the dateline and beyond to the east.  Very good news. Of much interest were the anomalies from climatological norms, with western anomolies blowing solidly in the region west of the dateline and now solid westerly anomalies were moving into the the region east of the dateline to a point south of Hawaii.  This is the first such event for this El Nino and if anything was on the upswing. For weeks now (since 9/8) a moderate westerly anomaly has been in.cgiay from the west up to the dateline. These westerly anomalies started with Typhoon Dujuan and continued with Choi-Wan gently feeding the subsurface warm water flow. And then with Parma and Melor, that flow was enhanced. And now yet more anomalies a full Westerly Winds are occurring. At a minimum it suggests reinforcements for the developing Kelvin Wave depicted on the dateline (see above) if not causing yet another Kelvin wave to develop. And that in-turn will reinforce the Kelvin Wave impacting Central America.  Not too bad. Will be interesting to see if this building westerly anomaly holds for the next week or so (into 10/15).

At this time we are saying this developing El Nino is past the critical juncture, and will survive in some fashion with effects continuing in the atmosphere until at least the Spring of next year. All data suggests this will not be a strong El Nino, more likely a weak to moderate one. NOAA's most recent update (today 10/8) forecasts the same outcome, though hints at a possible intensification (but not likely). A solid accumulation of warm water in the equatorial East Pacific is evidence in-favor of continued development. As long as there continues to be WWB's (as there obviously is), then warm water will be migrating east, and the warm water pattern will hold if not build, and the atmosphere above it will respond in kind to the change (towards El Nino). At this point there is no evidence to suggest this El Nino will stall or dissipate. The only remaining question is whether it will hold, or grow. And current data indicates that the warm pool will hold if not slowly build. And historically it is already larger and strong than any other in the past 12 years. 

The next milestone we're monitoring is development of this Active Phase of the MJO occurring now (10/3). The models indicate it is moderate in strength and should hold for a few weeks. Also water temps need to hold if not build (as is happening now). Our thoughts are that El Nino might gain a little more strength, but not much, with a 2 degree water temp anomaly in the tropical East Pacific the likely outcome. Coverage is pretty solid for this event, but the lack of really high water temp anomalies will likely limit it's strength. Strong El Ninos bring lot's of bad weather to the US West Coast, along with the potential for storm and swell enhancement. A moderate El Nino provides storm and swell enhancement, a gentle but steady push/momentum in-favor of storm development rather than the manic frenzy of a strong El Nino, but without all the weather associated with a strong event. So in many ways a moderate El Nino is more favorable from a surf perspective. As of right now things remain better than anything the Pacific has seen in the past 12 years regarding anomalous sea surface temperatures, besting anything since the big El Nino of 1997. That is very good news.  But the lack of anomalous water temps exceeding 3 degrees and an unremarkable SOI suggests a modest El Nino at best. Still, it should be enough to provide storm enhancement, and a better than average winter surf season for the North Pacific, and still likely better than anything in the past 10 years. Better yet, if it's not too strong (as this event appears to be) perhaps it will not degrade into La Nina the year after (which typically happens after stronger El Ninos), but hold in some mild El Nino like state for several years in a row. This would be an even better outcome.   

See more details in the new  El Nino update.


South Pacific

Beyond 72 hours the models suggest another weak gale low is to build under New Zealand on Monday (10/12) pushing east-northeast with up to 40 kt winds resulting in a modest sized area of 32 ft seas at 52S 180W mid-Monday into mid-Tuesday (10/13). Will believe it when it happens.

They are firm believers that a little learning can go a long way to help your surfing.  This is a great article to help convince your friends that they can benefit from being able to read the data themsleves rather than just relying on the forecasts of others.  See the full thing here:  Create Your Own Surf Forecast with Stormsurf

Mavericks - Everest of the Sea & Longboard Vineyards: Come late October Sonoma County will not only welcome a new crop of world class wines, but the award winning photography of some of Action Sports best lensmen. “ Mavericks – Everest of the Seas” comes alive again just in time to set the stage for another epic Big Wave Season. Mix two of Northern California's finest institutions – big wave surfing and the wine country – and you have what promises to be an amazing weekend at the Longboard Vineyards Tasting Room in Healdsburg
October 23 – 25.

Relive heroic battles between man and wave as seen through the eyes of the cutting-edge photojournalists who risk life and limb to document the wave's intense man-against-the-sea drama and obsessive lifestyle of Maverick's elite riders. Oded Shakked, a longtime surfer who founded Longboard Vineyards, will be unveiling his latest release, The Peter Mel/Mavericks Cabernet Sauvignon. This signature wine will be blended by not only Shakked but guest vintner, Peter Mel. Mel, one of the most respected names in Big Wave Surfing is known as perhaps the most skillful surfer ever to ride Mavericks. The famed spot off the Half Moon Bay. In October of 1998 he was whipped into to what is now considered the biggest wave ever ridden… Mel along with the featured photographers, surfboard shapers and wine makers will be on hand for the Friday night reception. The reception will begin at 5pm and run until roughly 9pm.

Longboard Vineyard has always had a soft spot for surfers. It's a.cgiace where you can hangout at a redwood-surfboard bar, or sa.cgie one
of its award winning wines while kicking back on a comfortable sofa watching surf movies. For this harvest weekend event Shakked has
enlisted “Mavericks: Everest of the Seas,” the heralded collection of Mavericks surf photography from Frank Quirarte, Doug Acton, Seth
Migdail and Ed Grant.

“Everest of the Seas” first made its debut recently at the Coastal Arts League Gallery in Half Moon Bay, drawing large crowds and an
enthusiastic response. It just finished a one-month highly successful run at San Francisco's world class Museum and Gallery, SFMOMA.“Everyone who sees the exhibit is just blown away,” said Grant, the curator of the Coastal Arts League Gallery. “Both surfers and non-surfers can't help but get caught up in the energy and stoke that surrounds Maverick's, the surfers and photographers who put it on the
line every time they go out there.”

The event also represents a high point in the career of Oded Shakked, who was born in Israel and grew up near a beach just north of Tel
Aviv. Immersed in surfing from the start, he made several trips around Europe's Atlantic coast while discovering, to his delight, that “it
was easier, cheaper and safer to drink good red wine than bottled water.” His twin loves of surfing and wine brought him to California,
where he studied winemaking at UC Davis and became enamored with the pe.cgie, climate and rich soil of Sonoma County. He founded Longboard Vineyards with the motto “Wine, waves and soul,” making it a highly unique fixture in wine country.

The October 23-25 weekend will also feature the sale of surfboards and memorabilia, along with Acton's acclaimed book, “Inside Maverick's.”
Admission is free. Opening reception sponsored by Maverick Events and Longboard Vineyards

Wave Model Upgrade Status Report: At this point we believe the installation of the new wave models is complete, with no problems being reported, the server stabilizing and the much requested return of the old style hemispheric Surf Height models now operational (again) and running side-by-side along the new ones. We thank you for your patience and input as we went though this process.  Your feedback helps guide our efforts and ultimately results in a better product for everyone.  Now we're off to start providing better menus to some wave model products most of you probably haven't uncovered yet (site specific graph and text forecasts), updateing the wave model FAQs and then upgrading the Weather Models.  

New Wave Model Facts: Click HERE to read more about the new wave models. Important info.

Stormsurf Wave Models Updated: On Friday (2/6) we installed the latest upgrade to our wavemodels. A year in the works, this upgrade essentially is a total re-write of every wave model product we produce. They now take advantage of the new Version 3 of the Wavewatch wavemodel. This version runs at a much higher resolution, specifically 0.0 X 0.5 degrees for the global grib with local products at 0.1667 X 0.1667 degrees, and it uses the hi-res GFS model for wind speeds. And of even more interest, the model now identifies primary swell and windwave variables. As such we now have new model images which displays this data. Also we've included out special 3D topographic land masks into all models. In all it makes for a radical step forward in wave model technology. We'll be upgrading minor components (FAQ, new menu pages etc) for a few weeks to come, but all the basics are available for your use now. Check it out here:
