Swell Classification Guidelines

Significant: Winter - Swell 8 ft @ 14 secs or greater (11+ ft faces) for 8+ hours (greater than double overhead).
- 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/Utility Class: Winter - Swell and period combination generating faces at head high to 1.5 times overhead (4-7 ft).
- 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.
- up to waist high swell. Also called 'Background' swell.

Surf Heights for Hawaii should be consider 'Hawaiian Scale' if period exceeds 14 secs.

Current Conditions
On Wednesday (3/16) North and Central CA had set waves at about 12-13 ft and lined up and somewhat closed out and powerful but with a fair amount of lump on top. Protected breaks were 2 ft overhead and lined up if not closed out and lumpy and uneven. At Santa Cruz surf was up to double overhead on the rare sets early and fairly clean. In Southern California/Ventura waves were 2 ft overhead and lined up with good form but horribly warbled from outer winds though local wind was calm. Central Orange County had sets at head high and lined up with decent form but soft and pretty warbled. South Orange County's best summertime breaks were thigh high and clean and soft. North San Diego had sets 1 ft overhead and lined up and clean but very inconsistent. Hawaii's North Shore had sets at 1-2 ft overhead and line dup and clean with decent form. The South Shore was thigh high on the sets and clean and weak. The East Shore was waist high and warbled from modest east trades.

See QuikCASTs for the 5 day surf overview or read below for the detailed view.

Meteorological Overview
On Wednesday (3/16) California was getting solid swell from a small but respectable system that developing north of Hawaii on Sat (3/12) forecast pushing east up to British Columbia on Mon (3/14) with seas to 46 ft aimed east. And Hawaii was still seeing sideband swell from the same system. A weak system is tracking over the dateline Wed (3/16) producing 26 ft sea aimed east but fading in 24 hours. And perhaps another system is to be developing on the dateline Fri-Sun (3/20) with seas to 29 ft with residuals tracking northeast through the Gulf on Mon (3/21) rebuilding with seas to 32 ft over a tiny area.

See all the details below...


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

North Pacific

On Wednesday (3/16) the jet was weak and somewhat split running from Japan over the dateline and into North California with winds never exceeding 110 kts only in small pockets with no troughs indicated offering no support for gale development.Over the next 72 hours the jet is to get more energetic with winds building to 150 kts by Fri (3/18) forming a trough over the dateline and another in the Central Gulf supporting gale development with the Gulf trough pushing over Oregon on Sat (3/19) and the Japan trough over the dateline and weakening some. Beyond 72 hours starting Mon (3/21) a trough is forecast over the Kuril Islands dragging the jet well up into the Bering Sea then falling hard south forming another trough in the Western Gulf and somewhat pinched then ridging hard northeast and pushing over Vancouver Island before falling hard south down over the US West Coast. Support for gale development is possible in the Gulf trough. By Wed (3/23) the jet is to be split just off Japan with the northern branch running east on the 45N latitude line with no troughs forecast and the southern branch falling down to the 15N latitude line then running due east offering nothing. This looks very much like a Springtime pattern.

Surface Analysis
On Wednesday (3/16) solid swell from a storm that tracked through the Western Gulf was fading in Hawaii and past it's prime in California (see West Gulf Storm below).

Over the next 72 hours starting Tues PM (3/15) a tiny gale was developing over the dateline producing 45 kts north west winds and seas building from 23 ft at 41.75N 176.25E aimed southeast. On Wed AM (3/16) the gale is to be just east of the dateline with 30-35 kt west winds and seas fading from 24 ft over a small area at 41N 179W aimed east. In the evening 25 kt west winds are to be fading fast aimed east with 19 ft seas at 40N 172W aimed east. The gale is to be gone after that. Small swell possible mainly for Hawaii.

Oahu: Expect swell arrival on Sat (3/19) at 3.4 ft @ 13 secs early (4.5 ft). Swell fading out Sun AM (3/20) from 2.3 ft @ 11 secs early (2.5 ft). Swell Direction: 322 degrees


West Gulf Storm
A storm developed Fri PM (3/11) just east of the dateline with 50-55 kt west winds and seas building from 23 ft at 37.5N 176.5W aimed east. On Sat AM (3/12) the storm had 50-55 kt northwest winds with seas 39 ft over a small area at 4.251N 167.75W aimed east.

MJO/ENSO Forecast


La Nina Weakening - Kelvin Wave Erupting - No Warm Water Behind
Summary - Cool subsurface water volume peaked under the equatorial Pacific on 10/15/21 and is now fading. A stronger than expected Active Phase of the MJO in Dec produced a Kelvin Wave that is erupting over the Galapagos with water temps on the rise there, but still solidly in La Nina territory over the Central Pacific. A much hoped for Active Phase of the MJO (and westerly anomalies) has been delayed per the models (was early March/now late March). It seemed the the peak of La Nina was behind us. But a solid bout of east anomalies is now to hold to late-March per the CFS model with a 3rd year of La Nina projected. But that is not certain either. The outlook is unclear but seems biased towards another year of La Nina.

MJO/ENSO Discussion
The Madden Julian Oscillation (MJO) is a periodic weather cycle that tracks east along the equator circumnavigating the globe. It is characterized in it's Inactive Phase by enhanced trade winds and dry weather over the part of the equator it is in control of, and in it's Active Phase by slackening if not an outright reversing trade winds while enhancing precipitation. The oscillation occurs in roughly 20-30 day cycles (Inactive for 20-30 days, then Active for 20-30 days) over any single location on the planet, though most noticeable in the Pacific. During the Active Phase in the Pacific the MJO tends to support the formation of stronger and longer lasting gales resulting in enhanced potential for the formation of swell producing storms. Prolonged and consecutive Active MJO Phases in the Pacific help support the formation of El Nino. During the Inactive Phase the jet stream tends to split resulting in high pressure and less potential for swell producing storm development. Wind anomalies in the Kelvin Wave Generation Area (KWGA) are key for understanding what Phase the MJO is in over the Pacific. The KWGA is located on the equator from 135E-170W and 5 degs north and south (or on the equator from New Guinea east to the dateline). West wind anomalies in the KWGA suggest the Active Phase of the MJO in the Pacific, and east anomalies suggests the Inactive Phase. In turn the Active Phase strengthens and the Inactive Phase weakens the jetstream, which in turn enhances or dampens storm production respectively in the Pacific.
And the El Nino/La Nino cycle (collectively know as ENSO - El Nino Southern Oscillation) is a less frequent (about once every 7 years) but more impactful cycle that affects world wide weather. Specifically, strong El Nino events promote storm production in the Pacific while La Nina events suppress storm production. These therefore have a significant impact on the production of swell and surf. The paragraphs below analyze the state of the MJO and ENSO in the Pacific and provide forecasts for upcoming activity (or inactivity depending on the state and interaction of these two oscillations).

Overview: In 2019 warm equatorial waters were fading, and by August a tongue of cool water was tracking west on the equator from Ecuador over the Galapagos reaching to a point nearly south of Hawaii. A bit of a recovery tried to occur during Fall of 2019, with weak warm water building in the Nino 1.2 region, but cool water held in a pool off Peru. By April 2020 a cool pool was starting to build, forming a well defined cool tongue that evolved into La Nina, with it fully developing through July 2020. A slow dissolving of La Nina started in March 2021 with 2 Kelvin Waves sweeping east and arriving over the Galapagos in June. Weak warming set up over the equator with no cool waters present. NOAA declared La Nina dead. But cold water returned in July 2021 and a second pulse of La Nina developed and is continuing today, though possibly weaker with its foundation appearing to be in decline.

Fall /Winter 2021-2022 = 1.5 (California & Hawaii)
Rating based on a 1-10 scale: 1 being the lowest (small and infrequent surf conditions), 5 being normal/average, and 10 being extraordinary (frequent events of large, long period swells)

Rationale: It was assumed that the moderate La Nina from the Winter of 2020/2021 was on the wane and that a return to neutral ENSO state would set up over the Pacific Basin through the summer of 2021. But La Nina made a strong return by the end of Sept much like what the CFS model suggested would happen. A full double dip La Nina pattern took hold as we moved into November with this second La Nina dip being nearly as strong as the previous one. But a quick fade is forecast as we move into late December with the CFS predicting a return to a neutral wind anomaly pattern at that time and the low pressure bias making headway in to the KWGA in early Jan. Still it will take some time for the atmosphere to fully respond, resulting in a less than normal swell production forecast especially for Fall into early Winter. But by later in Feb 2022 perhaps a return to a more normal pattern might take hold. But it will be too little too late. As a result a significantly reduced number of storm days and storm intensity is expected Oct-Feb 2022, resulting in a below normal level of swells, with swell being below normal duration and period. But by March 2022, the number of storm days, intensity and duration of those storms should start improving as La Nina fades out. The status of the PDO is not known, though it appears to be returning to at least a neutral state, rather than the warm phase as previously projected thereby having no significant positive or negative effect on the long term outlook.

KWGA/Equatorial Surface Wind Analysis (KWGA - Kelvin Wave Generation Area - The area 5 degrees north and south of the equator from 170W to 135E)
Analysis (TAO Buoys): As of (3/15) 5 day average winds were strong from the east over the Eastern equatorial Pacific and strong east over the Central Pacific and strong east over the KWGA. Anomalies were neutral over the East equatorial Pacific and modest east over the Central Pacific and modest east over the KWGA. (Note: These are 5 day average winds, versus realtime, so they lag what is happening today (by about 2.5 days).
1 Week Forecast (GFS Model): On (3/16) strong east anomalies were filling the KWGA. The 7 day forecast calls for strong east anomalies holding in the core of the KWGA through 3/21 then collapsing to near nothing the end of the model run on 3/23. But no west anomalies are forecast in the KWGA either.

Kelvin Wave Generation Area wind monitoring model: West and East

MJO/WWB/Wind Projections:  
OLR Models: (3/15) A solid Inactive MJO signal was indicated today in the KWGA. The statistical model indicates the Inactive signal slowly tracking east and almost east of the dateline on day 15 of the model run with the Active Phase strong over the Maritime Continent and trying to push into the KWGA. The dynamic model projects the same but with the Inactive signal stronger on days 5-10 then fading to weak status at day 15 of the model run and effectively east of the KWGA with the Active Phase moving into the far West KWGA.
Phase Diagrams 2 week forecast (ECMF and GEFS):
(3/16) The statistical model depicts the Active Phase was modest over the East Indian Ocean and is forecast tracking east to the Central Maritime Continent at day 15 of the model run and weak. The dynamic model suggests the same.
40 day Upper Level Model (assumed to be a statistical mode and 1 week ahead of what is occurring at the surface): (3/15) A moderate Inactive MJO signal (dry air) was filling the East equatorial Pacific today. The forecast depicts the Inactive Phase (dry air) is to move steadily east and into Central America on 3/22. The Active Phase (wet air) is to set up in the West Pacific on 3/20 pushing east and moving into Central America on 4/9. The Inactive Phase is to follow moving over the KWGA on 4/9 and over the East equatorial Pacific at the end of the model run on 4/24.
4 Week CFS Model (850 mb wind): (3/15) A weak Inactive MJO signal was indicated today in the far West KWGA with moderate to strong easterly anomalies filling the KWGA. The forecast has the Inactive MJO signal holding through 3/20 then fading before making significant progress into the KWGA with strong east anomalies through the same time period then rapidly collapsing on 3/23. Beyond the model suggest weak to modest east anomalies returning filling the KWGA 3/29 through the end of the model run on 4/12 while west anomalies try to get a toe in the door in the far West KWGA 4/29 holding through the end of the model run on 4/12.
3 Month CFS Model (850 mb wind): (3/16 - using the 5th ensemble member - the mean of the 4 individual members which are all from the 00Z run - 1 run per day):
Today the Active Phase of the MJO was pushing east over the KWGA to the dateline but producing no west anomalies. Instead strong east anomalies were filling the KWGA. The forecast depicts the Active Phase holding over the KWGA in earnest through 3/18, then backtracking some on 3/24 with east anomalies strong over the KWGA. Then the Active Phase is to push hard east fully over the KWGA on 4/1 holding through 5/1. West anomalies are to rapidly take over the entirety of the KWGA 4/1 and beyond, even as the Active Phase fades. A weak Inactive MJO signal is to follow starting 4/17 holding through the end of the model run on 6/13 but with west anomalies filling most of the KWGA to the dateline through the end of the model run. The low pass filter indicates a high pressure bias with 2 contour lines was centered east of the dateline at 150W with its western perimeter at 175E today and forecast holding there until pushing east of the dateline on 5/19. A broad single contour low pressure bias is established centered over the Maritime Continent at 110E with it's leading edge at 150E filling half the KWGA and is forecast stalled there till 4/1, then moving slowly but steadily east reaching 175E at the end of the model run. Today a solid east anomaly pattern that had been in control of KWGA since early July is supposedly taking it's last stand and will be gone before the end of March. A return to a normal MJO alternating pattern is setting up. And the low pressure bias is to start building reaching the dateline region in lat May signaling the full demise of La Nina. That said, there is only one more Active MJO forecast for this winter, starting now meaning only one more shot at support for some sort of gale/swell production. And the model has been constantly shifting the arrival of the low pressure bias almost daily. So the future is very uncertain.

Subsurface Waters Temps
TAO Array: (3/16) Today in the far West Pacific the 29 degree isotherm was backtracking to 163E. The 28 deg isotherm line was backtracking to 172E. The 24 deg isotherm was steady at 95W but the 25 degree isotherm was weakening and almost gone at 120W. Anomaly wise, warm anomalies +2 deg C were in a pocket in the far West Pacific down 150m backtracking to 150W with a previous Kelvin Wave in the East Pacific at +2C down 65m centered at 105W pushing east. A broad area of neutral to -1C cool anomalies were in between the two centered at 120W. The hi-res GODAS animation posted 3/9 indicates the same the pocket of cool anomalies between 155W-115W and appearing to be expanding in coverage. The GODAS animation appears to be 1 week behind the TAO data but also is more detailed and accurately modeled.
Sea Level Anomalies: (3/9) Sea heights were neutral over the Equatorial Pacific. A string of weakly positive anomaly pockets were north of the equator from just west of the Galapagos to the dateline. A broad pocket of weakly negative anomalies was just south of the equator at 140W. Otherwise positive anomalies were mostly locked west of the dateline. Per the Upper Ocean Heat Anomaly Histogram the previous Kelvin Wave was holding between 90W-112W with weak cool anomalies between 115W-175W. It is unknown whether cool anomalies will return in earnest moving forward.

Surface Water Temps
The more warm water in the equatorial East Pacific means more storm production in the North Pacific during winter months (roughly speaking). Cold water in that area has a dampening effect. Regardless of what the atmospheric models and surface winds suggest, actual water temperatures are a ground-truth indicator of what is occurring in the ocean. All data is from blended infrared and microwave sensors.
Satellite Imagery
Hi-res Nino1.2 & 3.4 Qualitative Analysis: (3/15) The latest images depict a broad generic pool of cool water on the equator extending west from a point south of California dissipating on the dateline. Warming waters were building from Ecuador west beyond the Galapagos to 120W. A shallow area of cool waters were along the immediate coast of Peru. An area of warm water was holding just north of the equator across the entire North Pacific. Overall this indicates the late stages of La Nina.
Hi-res 7 day Trend (3/15): Solid warming was holding from Ecuador west on the equator to 140W and reaching 10 degrees north and south of the equator. No cooling was indicated.
Hi-res Overview: (3/15) The deep cold core of the La Nina cool pool is gone. Residual cool waters were still covering a large area starting well off Peru at 90W and on the equator from 115W and points west to 160E. Cooler than normal waters were also south of that line down to 20S though losing coverage and intensity. Warmer than normal waters were aligned from 3N and above over the entire North Pacific. La Nina is solid but appears to be fading focused over the equatorial Central Pacific.
Nino1.2 Daily CDAS Index Temps: (3/16) Today's temps continue upward at +0.458 and have been moving upwards since 2/20, and beating a previous high of -0.650 degs on 1/9 and that after being down at -1.871 on 1/3 and -1.954 on 12/18, the lowest this year so far. Previously temps dropped on 11/24 at -1.700, the lowest in months after previously toggling steady at about -0.6 degs from mid Aug to Oct 6, then falling from there. Last year temps bottomed out at -2.138 on 8/13/20. The longterm trend has been steadily downward.
Nino 3.4 Daily CDAS Index Temps:
(3/16) Today's temps were steady at -0.946 (slowly rising since 3/9) after falling to -1.012 on 3/8 after rising slightly to -0.505 on 2/2 and that after reaching a peak low of -1.096 on 1/3 beating the previous low of -1.080 on 11/2, the lowest in a year. Prior to that temps had been in a freefall starting from the -0.175 range in early Sept. Before that temps peaked up at 7/1 +0.332, the highest in a year. Temps previously had been steady near -0.222 since early March. Temps bottomed out at -1.654 on 11/3/2020.

SST Anomaly Projections
CFSv2 Uncorrected Data
Previous - Temps rose in early Nov 2020 after bottoming out at -1.25 degs, up to -0.01 degs in mid-June 2021 then fading to -1.05 degs in mid-Nov then rebuilding to -0.7 in mid Feb 2022.
Forecast (3/16) - T
emps are to fall to -1.5 degs in early May and holding unchanged till Nov then rising to -1.15 degs in Dec. This model suggests we are at going to fall into a third year of La Nina. The PDF Corrected forecast suggests temps falling to -1.30 degs in May then rising to -1.15 degs in July and roughly holding there. Still, neither of these forecasts are consistent with the IRI forecast (see IRI Consensus forecast below).
IRI Consensus Plume: The Feb 18, 2022 Plume depicts temps are -0.704 degs today and have bottomed out. They are to warm to -0.438 degrees in April, then rising to -0.026 degs in July and hovering near 0,0 degs after that. A return to ENSO neutral is expected this summer.

Atmospheric Coupling (Indicating the presence of El Nino in the atmosphere driven by the ocean):
Southern Oscillation Index (SOI) (negative is good, positive bad - this is a lagging indicator):
Today (3/16) the daily index was positive at 21.06 after peaking at +27.33 on 1/31/22 and +46.71 on 12/26. The trend of late has been solidly positive. Previous other notable peaks were +30.98 on 11/26, +36.90 on 9/28, +27.75 on 9/13 and +37.86 on 7/15.
The 30 day average was rising some at +10.86 after falling to +0.83 on 1/27 then peaking at +13.07 on 12/31 (the highest in a year) after previously falling to +6.06 on 11/6 after peaking at +11.58 on 10/22. Before that it fell to -3.36 on 6/22, the lowest in a year. It peaked at +19.51 on 1/14.
The 90 day average was steady at +8.15 today after previously peaking at +10.90 on 12/26, falling to +7.10 on 11/1. It previously peaking on 9/21 at +9.80 after falling to it's lowest point in a year on 6/9 at +1.06. The 90 day average peaked at +15.75 on 2/23 (clearly indicative of La Nina then). This index is a lagging indicator but suggest La Nina is returning.

Pacific Decadal Oscillation
The PDO theoretically turned from a 16 year negative run (Jan 98-Feb 2014) in early 2014 and was positive till Dec 2019, but has been negative ever since, driven by recent La Nina conditions. In May-July 2021 it was the most negative its been in the -1.80 to -2.04 range since Sept 2012 (-2.99) and then fell to -3.16 in Oct 2021 (the lowest since July 1933) then settled at -2.72 in Nov and Dec 2021. Looking at the long term record, it seems likely we are still in the Cool Phase of the PDO (La Nina 'like') with no signs of moving to the positive/warm phase (El Nino 'like').
