PACIFIC OVERVIEW
Current Conditions
On Saturday (2/26) North and Central CA had set waves at 2 ft overhead and lined up with good form and glassy and well rideable. Protected breaks were chest high on the sets and clean but inconsistent. At Santa Cruz surf was waist high or so on the sets and clean and soft and inconsistent. In Southern California/Ventura waves were thigh high on the sets and lined up and clean with decent form with modest northeast/offshore winds. Central Orange County had sets at thigh to waist high and clean and with decent form and slightly lined up when they came with calm wind. South Orange County's best summertime breaks were thigh high and somewhat lined up and weak and clean and barely rideable. North San Diego was thigh high or so on the sets and clean and soft. Hawaii's North Shore was still solid with waves in the 8-10 ft range and lined up and clean and powerful and out of control at most breaks. The South Shore had a few thigh high sets and clean and weak. The East Shore was waist high and chopped from moderate east trades.

Meteorological Overview
On Saturday (2/26) swell was still hitting Hawaii and poised for California originating from a broad system that developed just off the Kuril Islands Mon-Tues (2/22) producing 39 ft seas aimed east then dissipating before reaching the dateline. After that a weak gale is forecast in the Central Gulf Sun-Tues (3/1) producing 30 ft seas targeting from Pt Conception northward and sideband energy towards Hawaii. And perhaps a stronger system to develop over the dateline Wed-Fri (3/4) producing up to 42 ft seas aimed east. And maybe a smaller one to follow over the dateline on Fri-Sat (3/5) with 31 ft seas targeting Hawaii well.

Overview
Jetstream
On Saturday (2/26) the jet was consolidated pushing firmly east off Japan on the 34N latitude line with winds to 170 kts pushing flat over the dateline to 145W but not forming any troughs though still supportive of gale development just based on wind speeds alone. The jet was split east of 140W with the northern branch weakly pushing into British Columbia with high pressure aloft barely holding over California. Over the next 72 hours wind energy in the eastern portion of the jet is to evaporate but with the jet still pushing east and recovering in the east to 145W while 150 kts winds holding over the Western Pacific and over the dateline to a point north of Hawaii. Still no troughs forecast but still offering some support for gale development based on wind speeds alone. Beyond 72 hours starting Wed (3/2) the jet is to retrograde with winds building to 180 kts from Japan to the dateline but splitting east of there and then weakening even over the western portion with winds in the 150-160 kt range in pockets and no troughs forecast through Thurs (3/3). Finally on Sat (3/5) winds to rebuild over Japan at 190 kts with a steep trough setting up on the dateline offering good support for gale development. The jet is to start fully splitting at 155W with the northern branch pushing into British Columbia and down the entire US West Coast possibly offering some weather there.

Surface Analysis

La Nina Evaporating - Kelvin Wave Still Pushing East
Summary - Cool subsurface water volume peaked under the equatorial Pacific on 10/15/21, beating last years volume, but is quickly fading at the surface in the East Equatorial Pacific. A stronger than expected Active Phase of the MJO in Dec has produced a Kelvin Wave that is plodding east through the East Pacific. Water temps appear to be warming over the entire East Pacific, though still in La Nina territory for the moment. A return to a more normal cadence of Active and Inactive MJO phases is starting now. It seems the the peak of La Nina is behind us. But the atmosphere will take much time to respond. And an influential model persistently suggests a return back to La Nina this coming Summer.

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.

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 (2/25) 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 moderate east over the East equatorial Pacific and moderate east over the Central Pacific and moderate 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 (2/26) strong east anomalies were filling the KWGA. The 7 day forecast calls for strong east anomalies holding in the core of the KWGA to the end of the model run on 3/5 then possibly weakening.

MJO/WWB/Wind Projections:
OLR Models: (2/25) A moderate Inactive MJO was filling the KWGA. The statistical model suggests the Inactive Phase is to slowly fade in coverage and strength on day 5 of the model run to weak status then gone on day 10 with a weak Active Phase building into the Western KWGA on day 15 of the model run. The dynamic model projects the Inactive Phase fading slower but gone by day 15 of the model run with the Active Phase starting to push solidly into the West KWGA then.
Phase Diagrams 2 week forecast (ECMF and GEFS): (2/26) The statistical model depicts the Active Phase was weak over the East Indian Ocean and is forecast slowly moving to the far West Pacific while fading in strength to very weak status over the next 15 days. The dynamic model suggests Active Phase moving at the same speed to the far West Pacific at day 15 of the model run but at modest strength.
40 day Upper Level Model (assumed to be a statistical mode and 1 week ahead of what is occurring at the surface): (2/25) The Inactive Phase of the MJO (dry air) was over the far East Pacific today with the Active Phase moving over the far West Pacific. The forecast indicates the Active Phase (wet air) moving into the KWGA on 3/1. The Active Phase (wet air) is to track east filling the equatorial Pacific weakly on 3/7 then moving east and over Central America while weakening on 3/22. A new coherent Inactive Phase (dry air) is to build over the KWGA on 3/22 moving rapidly east and into Central America at the end of the model run on 4/6 and fairly strong.
4 Week CFS Model (850 mb wind): (2/25) The Inactive Phase of the MJO is depicted peaking while filling the KWGA today with modest to moderate easterly anomalies filling the KWGA. The forecast has east anomalies building in coverage and strength filling the KWGA at strong status 2/26-3/5 as the Inactive Phase makes it's final push east across the KWGA. The Active Phase is to start moving into the the West KWGA on 2/27 and holding through 3/18. West anomalies are to only move west to 150E at moderate strength by 2/29 then holding there into 3/15 with east anomalies filling the eastern KWGA through the end of the model run while weakening to modest strength.
3 Month CFS Model (850 mb wind): (2/26 - 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 Inactive Phase was over the Eastern KWGA trying to hold on with moderate to strong east anomalies filling the KWGA. The forecast has east anomalies slowly tracking east over the KWGA holding in strength through 3/5 on the dateline as the Inactive Phase pushes east and fully east of the KWGA with east anomalies fading some. The Active Phase of the MJO today was over the western KWGA but stalled, but is forecast to start pushing east 3/2 and filling it on 3/9 with west anomalies moving east from the Maritime Continent into the West KWGA on 3/5 then stalling at about 150E. The Active Phase is to hold over the KWGA through 4/23 with moderate west anomalies stalled at about 150E then slowly starting to push east in earnest on 4/15 finally filling the KWGA after that. The Inactive Phase is to develop 4/15 in the West KWGA tracking east through the end of the model run on 5/26 with neutral to weak west anomalies in control the whole time. The low pass filter indicates a high pressure bias with 1 contour line was centered east of the dateline at 150W with its western perimeter at 175E today and forecast holding then pushing east of the dateline 4/25 and slowly easing east from there. A broad single contour low pressure bias is established centered over the Maritime Continent at 100E with it's leading edge at 140E and barely in the KWGA but is forecast starting to creep east into the KWGA starting 3/14 then filling 75% of the KWGA on 4/23 and building further east but never reaching the dateline as a second contour builds starting 5/5. Today a solid east anomaly pattern that had been in control of KWGA since early July is trying to dissipate, but is getting a second wind. A return to a normal MJO alternating pattern is setting up. And the low pressure bias is to start building approaching the dateline region in later April signaling the full demise of La Nina. That said, there is only one more Active MJO forecast for this winter, in the late Feb/early March timeframe meaning only one more shot at support for some sort of gale/swell production.

Subsurface Waters Temps
TAO Array: (2/26) Today in the far West Pacific the 29 degree isotherm was retrograding to 166E. The 28 deg isotherm line was steady at 179E. The 24 deg isotherm was easing east to 95W. Anomaly wise, warm anomalies +2 deg C were in a pocket in the far West Pacific down 150 m reaching east to about 150W with a previous Kelvin Wave in the East Pacific at +2C down 75m centered at 110W pushing east. No cool anomalies were under the Pacific. The hi-res GODAS animation posted 2/22 indicates a potential second Kelvin Wave in the West Pacific with it's leading edge at 150W and a second Kelvin Wave pushing east with 2-3 degs warm anomalies with its eastern edge at 95W with a tiny pocket of cool anomalies at -3 degs C 25 meters down and pushing to the surface at 85W while rapidly fading 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: (2/22) Sea heights were neutral over the Equatorial Pacific except one small area of -5 cms anomalies between over the Galapagos and losing coverage quickly. Otherwise positive anomalies were steady, locked at the dateline but with a finger of 0 to -5 cms on the equator from the dateline to 95W. A weak Kelvin Wave is pushing east. La Nina is trying to hold on but appears to be getting significantly challenged by warmer water encroaching from the west. Per the Upper Ocean Heat Anomaly Histogram La Nina subsurface cold temperatures are rapidly collapsing while being pushed east by the Kelvin Wave. Warm water was fast moving east with it's leading edge today at 95W. All this signals the demise of La Nina.

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: (2/25) The latest images depict a broad generic stream of cool water on the equator extending west from just off Ecuador over the Galapagos out to 140W then weaker west of there before dissipating on the dateline. A previous core of cooler water near the Galapagos (the core of La Nina) is gone. The classic La Nina pattern is in quick retreat. There are signs of warming along the coasts of Chile. But deep 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 (2/25): Warming was occurring from Ecuador west on the equator to the dateline. Warming was occurring off of Peru out to 130W. A small pocket of cooling was indicated over the Galapagos.
Hi-res Overview: (2/25) The magnitude of the core of the La Nina cool pool is gone. But weaker residual cool waters were still covering a large area from Peru up to the equator and west to 140W and weaker to the dateline. 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 East Pacific.
Nino1.2 Daily CDAS Index Temps: (2/26) Today's temps were up some at -1.314 after rising to -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: (2/26) Today's temps were steady at -0.744 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.

CFSV2 Forecast for Nino3.4 Sea Surface Temp (SST) Anomalies & Current SST Anomalies

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 (2/26) - Temps are to fall to -1.45 degs in May then rising slightly to -1.15 degs in July and holding beyond. This model suggests we are at going to fall into a third year of La Nina. The PDF Corrected forecast suggests temps falling to -1.20 degs in June then rising to -1.00 degs in July and holding beyond. Still, neither of these forecasts jive 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 (2/26) the daily index was positive at 19.79 after peaking at +27.33 on 1/31/22 and +46.71 on 12/26. The trend of late has been towards positive readings. 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 +9.21 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 +7.44 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').
