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 Sunday (10/25) North and Central California was getting more small northwest windswell for the Gulf of Alaska, the remnants of Storm #1 with waves chest high and conditions a bit breezy out of the north. Heavy fog in effect. Southern California was getting wrap around energy from this swell too with surf thigh to waist high and clean but socked in up north. Hawaii's North Shore had limited thigh to waist high northwest swell and clean. The East Shore had thigh high locally generated east windswell and chopped. The South Shore was flat.
The forecast for North and Central CA is for a little more northwest windswell coming from the Gulf on Monday at chest to maybe head high, fading out on Tuesday and becoming totally overridden by local north windchop. Wednesday that chop to reach 2-3 ft overhead at top exposed breaks with poor conditions, dropping to head high on Thursday and starting to clean up some. Southern California is to see more thigh high northwest swell at exposed breaks Monday then getting overridden by local northwest windswell at thigh high on Tuesday, building Wednesday to nearly chest high at exposed breaks and continuing at chest high on Thursday. The North Shore of Hawaii is to see more small northwest windswell, up a little Monday at chest high, then fading Tuesday at waist high on gone by Wednesday. Possible north swell to arrive later on Thursday. The East Shore is to continue with easterly windswell at thigh to waist high through the week. The South Shore is to remain flat for the workweek.
Longterm the Active Phase of the MJO remains firmly in-control and is expected to continue favoring the development of gales (or better) in the North Pacific. A new gale was developing off British Columbia on Sunday (10/27) producing barely 23 ft seas aimed due east, favoring the Pacific Northwest with some smaller swell, but followed quickly by strong high pressure and strong north winds likely setting up a windswell event Tuesday and continuing southward into at least Wednesday if not Thursday in California. And another weak gale is forecast for the Pacific Northwest Fri/Sat (10/31) too. A gale is forecast forming just east of the dateline on Tues/Wed generating up to 26 ft seas aimed dues south towards the Islands, pushing swell that way. But of more interest is the extratropical transformation of Typhoon Lupit off Northern Japan Tues (10/27) possibly getting rather intense while tracking northeast, positioned a long ways away from the US Mainland but decently on the great circle tracks to Hawaii. A turn to the east is forecast late Wednesday into Thursday possibly putting it on the dateline Friday (10/30) as it dissipates. This on is something to monitor but still a long way from even forming, so any outcome is far from guaranteed. Also the models continue suggesting a solid gale forming under New Zealand Wed/Thurs (10/29) with decent fetch aimed northeast, but that also is far from guaranteed. But there remains hope.
SHORT- TERM FORECAST
Current marine weather and wave analysis plus forecast conditions for the next 72 hours
On Sunday (10/25) the North Pacific jetstream continued running essentially flat on the 38N latitude pushing off Japan the rising gently pushing into British Columbia in the East. Pockets of 140 kt winds were scattered along it's length. There was no clear sign of support for gale development with no troughs in effect. Over the next 72 hrs a trough is forecast starting to build on the dateline Monday (10/26) quickly getting very steep with 160 kt winds flowing down into it Tuesday and nearly pinched off and useless by Wednesday. Still, decent support for gale development down at the surface appears likely. Also something that almost looks like a trough is forecast forming off the Kuril Islands late Tuesday pushing east to the dateline while moderating into Thursday (10/29). Limited support for development there too. Beyond 72 hours a generally weak and disorganized pattern is to take over on by Thursday (10/29) though next weekend though still generally consolidated on the 40N latitude. But wind speeds are to be way down.
At the surface on Sunday (10/25) high pressure at 1024 mbs was centered 600 nmiles off the Central CA coast ridging east and generating a fetch of 20 kt north winds pushing down the coast of North and Central CA generating limited north windswell there. Residual swell from previous fetch in the Gulf was slowly dissipating. A new gale was producing 35 kt west fetch 700 nmiles west of Washington and tracking east fast. 20 ft seas were modeled at 45N 148W. This fetch is to push east and into British Columbia late Sunday with 23 ft seas 600 nmiles off Washington Sunday evening pushing into the coast Monday AM (10/26). Larger unruly swell is the expected result for the Pacific Northwest.
Also on Monday (10/26) a gale is forecast to start building on the dateline with 35-40 kt north winds over a tiny area at 40N 180W building to 45 kts and sinking south fast in the evening at 32N 180W. 25 ft seas are modeled at 37N 180W aimed due south, mostly bypassing the Hawaiian Islands, at least initially. The fetch is to get better organized on Tuesday AM with 40 kt north winds at 37N 174W and aimed more to the southeast (towards Hawaii) with 26 ft seas developing in the same area. By Tuesday evening 30 kt north winds are to continue at 37N 171W with 26 ft seas modeled at 35N 172W all pushing well towards the Western Hawaiian Islands.30 kt north winds are to be fading at 35N 170W Wednesday AM with 23 ft seas pushing south, southeast towards the Western Hawaiian Islands. Assuming all this occurs, a bit of a leap of faith at this early date, some form a decent north swell could start impacting the Hawaiian Islands late Thursday (10/29) peaking early Friday (10/30) from 328 degrees. Will monitor.
Over the next 72 hours the extratropical remnants of Typhoon Lupit are to track north-northeast from the northern Philippines building off Japan Monday with a small fetch of 60 kts north winds building in the storms west quadrant Tuesday AM, then really surging in the evening with 65-70 kts winds wrapping into it's south quadrant at 43N 160E aimed well up the 305 degree path to NCal and the 310 degree paths to Hawaii. 44 ft seas are forecast at 43N 160E. This intense storm is to continue northeast on Wednesday AM (10/28) with 60-65 kt west winds forecast at 46N 167E aimed well down the 319 degree path to Hawaii and the 303 degree path to Central CA. A small area of 49 ft seas forecast at 45N 168W. In the evening 50-55 kts northwest to west winds are forecast wrapping into the storm south quadrant at 47N 170E aimed down the 322 degree path to Hawaii and the 304 degree path to Central CA 46 ft seas forecast at 47N 175E pushing mostly due east. Thursday AM (10/29) this system is to start decaying with 50 kts west-northwest winds at 48N 173E aimed reasonably well down the 325 degree path to Hawaii and the 305 degree path to Central CA. 43 ft seas forecast at 47N 175E. Residual 45 kt northwest winds are forecast in the evening at 48N 178E approaching the dateline aimed down the 331 degree path to Hawaii and the 305 degree path to Ncal with 40 ft seas fading at 47N 180E. This system to be dissipating fast after that. This systems is to be a long ways away from either Hawaii or the US west coast, and is to not be large in areal coverage. But it is to be very intense, assuming the models really have a handle on this one (something we are not will to believe yet). Still, it make for an interesting spectacle on the models and has been in place for the better part of 4 days now, so odds are creeping up in favor of it;'s development. At this point, it's only a curiosity and in now way do be believe it will play out as forecast.
North Pacific Animations: Jetstream - Surface Pressure/Wind - Sea Height - Surf Height
California Nearshore Forecast
On Sunday (10/25) high pressure at 1026 mbs was centered 600 nmiles west of Central CA ridging east into North CA resulting in 20 kt north winds nearshore from Cape Mendocino southward to Pt Conception and south of there but away from the coast. The high and associated north winds are to continue Monday, but pulled slightly away from the coast. But on early Tuesday (before sunrise) a weak front is to pass south over the state with high pressure surging behind it, setting up strong north winds at 25-30 kts building over the length of the state pushing 35-40 kt in the afternoon and reaching even into Southern CA. Warm surface water is likely to be blown away with horrendous conditions in effect. 30 kt north winds to continue on Wednesday (10/28) then settling down on Thursday though much turbulence and bump to persist in the ocean. By Friday a light to calm wind flow is expected to take hold into Saturday. Another small bit of high pressure and north winds are forecast for Central and by North Ca Sunday (11/1) but pulled just s smidgeon away from the coast.
With the MJO in the Active Phase, net tropical activity is up:
Super Typhoon Lupit was located roughly 600 nmiles east of the Northern Philippines on Sunday (10/18) with sustained winds 130 kts (150 mph) drifting northeast, effectively directionless. A turn back to the west occurred 24 hours later with Lupit accelerating some. On Thursday (10/22) Lupit had sustained winds 65 kts and was located 80 nmiles east of the northern tip of the Philippines. By Sunday (10/250 it was tracking northeast with winds 50 kts, expected to track parallel to the coast of Japan on Monday and accelerating in forward speed with winds 45 kts. Possible intensification is forecast in the days beyond (see Shortterm forecast for details).
Tropical Storm Neki remained drifting north positioned 300 nmiles northwest of Kauai with sustained winds 45 kts (all fetch aimed north). An acceleration in forward speed is projected. No swell producing fetch is suggested.
At the surface on Sunday (10/25) no swell producing fetch was occurring and none is forecast for the next 72 hours.
South Pacific Animations: Jetstream - Surface Pressure/Wind - Sea Height - Surf Height
Marine weather and forecast conditions 3-10 days into the future
Beyond 72 hours the remnants of the Lupit storm are to track over the dateline and slowly decay with 20 ft seas forecast pushing to a point 1200 nmiles north of Hawaii before completely dissipating. If this comes to pass pretty good dose of swell is likely for the entire Pacific Basin. But otherwise no swell producing weather systems are forecast.
MJO/ENSO Update (reference): As of Sunday (10/25) the Madden Julian Oscillation (MJO) continued in the Active Phase, and strongly. The ENSO (El Nino Southern Oscillation) index remaining negative with the Daily SOI index at -19.34, the 8th day in a row at that magnitude or higher attributable to low pressure under Tahiti and high pressure over Darwin Aus .(16 days in a row solidly negative and 29 consecutive days nearly negative/not positive). The 30 day average was falling to -11.92 and the 90 average was down to -4.32. This continues looking more like what would be considered real a El Nino state. The SOI index is likely to continue heading down for the days ahead driven by the Active Phase of the MJO, and has surpassed the depths it reached in June, the peak of this El Nino's SOI trend and approaching the deepest readings since April-July of the 2006 El Nino event.
Wind anomalies at the 850 mb level (approx 5000 ft up) as defined by models indicated light westerly anomalies over the entire equatorial Pacific from the West Pacific over the dateline and extending east into Central America. Mild eastern anomalies associated with the Inactive Phase of the MJO continue covering the Northern Indian Ocean. The Active Phase is to continue in the Pacific tracking east through 11/8, with a dead neutral pattern setting up after that through 11/13. The Inactive phase is to make it to the Philippines on 11/3, hold there, the dissipate. The current configuration and strength suggest that the MJO signal does in-fact die during El Nino events. Will monitor more. Our belief is that the mid-to-late October timeframe still looks like a good window for support of North Pacific Storm development, with the focus moving slowly east from the West Pacific tropics towards the Central Pacific (Hawaii and the Western Gulf of Alaska).
Sea Surface Temp anomaly data (10/22) continues to indicate steady changes over the past month, with the area of warmer than normal water expanding it's grip on the equator building solidly from west of the dateline (160E) over the dateline and 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 moderate El Nino. The expanse of the warmer waters continues to build north of the equator, solidifying it's grip up the coast of Mexico and Baja (though still retreated from Southern and Northern CA - the result of a local north wind/high pressure), and extending west almost to Hawaii then southwest to the dateline. And it is build some some south of the dateline too. If anything, this area is looking even stronger than even last update last week. 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 and even west of there now, then tracking southeast on to Northern Peru. This is not anything exceptional, but clearly a moderate El Nino. 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 any event since then (over the last 12 years) in terms of water temps and areal coverage and is only slowly building on that position. Cooler than normal waters we had been monitoring off Africa have been mostly wiped out.
Below the surface on the equator things continue to turn towards the good, better than the last update. 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. We have been expecting to see surface water temperatures jump up in Oct off Central America as the last Kelvin wave dispersed there, feeding the developing warm water pool and fueling El Nino. We think that is happening, but in a much more subtle way, with the trades in the area blowing warmer surface waters west. The latest imagery depicts the movement of warm waters to the west, and the expanse of those waters is increasing. So though the total temperature anomaly is not getting warmer off Central America, the expanse of those warm waters is increasing. A core of 2 deg warmer than normal water that first appeared under the dateline on 9/17 moved east to 175W by 9/22 and 172W on 9/24, then built to 3 degrees above normal (9/29) and continued growing as of 10/18 at 160W. Data on 10/20 depicted intensification with temps pushing solidly 4 degrees C above normal. And as of 10/22 that anomaly looked to be broaching the 5 degree mark and was holding if not expanding on 10/25. This is good. It was located at 150W pushing steadily east, much faster than previous Kelvin Waves. We've been looking for this one and it is associated with a persistent weak westerly surface wind flow that had been in-place west of the dateline from 9/8. It is expected to reach the coast of Ecuador late December (though possibly sooner), about at the peak of whatever El Nino will be in place for this winter. So all looks good for maintaining the existing warm pool for a while if not building it.
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-play since 9/27 and was associated with tropical systems Parma and Melor. This was 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 10/7 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. On 10/11 light west winds were still in effect to the dateline with solid anomalies over the dateline and to a point south of Hawaii. And by 10/13 a light west flow was in effect with full west anomalies still in place to the dateline and east to about Hawaii fading some into 10/20 but still light west winds were west of the dateline and anomalies east of there. Then on 1021 another batch of fully blowing west winds were in-play with solid anomalies to 160W (south of Hawaii) and almost to 140W, making further eastward progress than anything so far this El Nino event. By 1024 that pattern continued if not intensified with fully blowing west winds to the dateline a solid anomalies to 140W and maybe even more. This all remains very good news and is likely associated with the current new Active Phase of the MJO. The anomalous flow continues making more inroads towards the East Pacific. Again, this is classic El Nino symptoms. This is the first such event for this El Nino and if anything was on the upswing. For over a month now (since 9/8) a continuous moderate westerly anomaly has been in-play 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, Melor and Nepartak, that flow was enhanced. At this time all these anomalies appear to be consolidating the resulting warm waters into one strong Kelvin Wave, the one currently pushing east from the dateline (see above). This one is expected to reinforce the Kelvin Wave currently impacting Central America. .
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 (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.
Beyond 72 hours the models continue to suggest a gale is to start pushing east under New Zealand Wed-Thurs (10/29) producing a decent sized fetch of 40-45 kts southwest winds aimed well to the northeast generating 32-35 ft seas. This continue to be a real longshot for the models, but something to monitor just the same.

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 place where you can hangout at a redwood-surfboard bar, or sample 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 people, 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

North California Surf Report Works Again: After an extended downtime we finally got the North California Surf Report working again. Thanks for your patience. See it here: http://www.stormsurf.com/page2/report/ncal.html
Shark Video: Our friend Curt Myers of Powerlines productions shot this footage of 2 great whites munching on a whale carcass off Devils Slide (south of San Francisco) on Thursday. Kind of interesting to watch. Check it here: http://www.youtube.com/watch?v=8I4rZYEZMWQ (Fixed link)
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.
