PACIFIC OVERVIEW
Current Conditions
On Saturday (2/5) North and Central CA had set waves at head high to 1 ft overhead and lined up and glassy with good form. Protected breaks were chest high and lined up and somewhat closed out but clean. At Santa Cruz surf was waist to chest high and clean but soft. In Southern California/Ventura waves were thigh to waist high on the sets and lined up and clean with steady offshore wind. Central Orange County had sets to waist high and lined up and clean but inconsistent. South Orange County's best summertime breaks were thigh to rarely waist high and soft and clean with some texture on it. North San Diego had sets at up to waist high and lined up and soft and clean. Hawaii's North Shore had sets at 10 ft on the face and lined up and clean with good form. The South Shore was waist high with some bigger sets and lined up and real clean early but inconsistent. The East Shore was chest high and textured from light easterly wind.

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

Meteorological Overview
On Saturday (2/5) swell from a gale that previously developed over the South Dateline region Sun-Mon (1/31) with seas to 25 ft was fading in California. In Hawaii larger swell from a gale that developed over the North Dateline region Tues-Wed (2/2) with up to 35 ft seas aimed east was fading and pushing towards California. And another developed while lifting north through the far Western Gulf on Thurs-Fri (2/4) with 40 ft seas aimed east. But all were small in coverage and quickly tracking hard northeast with only small swell likely even under the best of circumstances. Another gale is to form on the dateline on Sun-Mon (2/7) lifting northeast with up to 37 ft seas aimed east. A secondary gale is to form over the Northwest Gulf Tues-Wed (2/9) producing up to 39 ft seas aimed northeast. A bit of a break and then perhaps to gale to form in the Northwestern Gulf and another west of the dateline on Sat (1/12).

SHORT- TERM FORECAST
Current marine weather and wave analysis plus forecast conditions for the next 72 hours

North Pacific

Overview
Jetstream
On Saturday (2/5) the jet was consolidated pushing firmly east off Japan on the 33N latitude line running east over the dateline to a point just north of Hawaii with winds 190-200 kts feeding a broad shallow trough just west of the dateline offering some support for gale development. East of there the jet split at 160W with the northern branch pushing northeast over Alaska supporting nothing but high pressure east of the split point. Over the next 72 hours no real change is forecast except winds fading some to 180 kts but with no clearly defined troughs forecast offering nothing more than what is occurring now to support gale development. Beyond 72 hours starting Wed (2/9) winds to fade to the 170 kt range and losing coverage with the jet starting to unzip back to the dateline by Sat (2/12) but with winds building over Japan to 190 kts at that time with a solid trough starting to dig out just west of the dateline offering good support for gale development. The jet has been projected to unzip in sync with the fading of the Active Phase of the MJO and the arrival of the Inactive Phase. But that has been delayed now till about 2/12. The main concern is whether that will have any significant effect on the jetstream or whether a developing and eastward moving low pressure bias over the West Pacific will trump the negative affects of the Inactive Phase of the MJO. It definitely an ambiguous outlook.

Surface Analysis
On Saturday (2/5) residual swell from a gale that previously formed over the South Dateline region was fading in California (see South Dateline Gale below). Swell from another gale previously over the North Dateline region was hitting Hawaii and bound for CA (see North Dateline Gale below). Also a gale developed while moving from the dateline to the Northwestern Gulf with seas building to 40 ft (see Northwestern Gulf Gale below).

Over the next 72 hours yet another gale is to develop on the dateline Sun AM (2/6) producing 50 kt west winds on the dateline and seas building from 33 ft at 39N 177.5E aimed east. In the evening 45 kt west winds are to be just east of the dateline lifting northeast over a decent sized area with seas 35 ft at 42.5N 174.5W aimed east. Fetch is to fade in coverage at 45 kts while pushing northeast Mon AM (2/7) with seas 37 ft at 43.75N 169W aimed east. The gale to quickly fade from there in the evening with 35 kt west winds and seas fading from 30 ft at 47N 163.25W aimed east. Something to monitor.

Oahu: Rough data suggest swell arrival on Wed (2/9) building to 4.6 ft @ 13 secs later (6.0 ft). Swell Direction: 316 degrees

South Dateline Gale
A gale developed on Sun AM (1/30) generating a small fetch of west winds on the dateline from the northwest at 35 kts producing seas of 23 ft at 34N 180W aimed east at mostly Hawaii. In the evening fetch held while falling southeast with seas 25 ft at 32.5N 176W aimed east. On Mon AM (1/31) fetch was fading from 30-35 kts with seas 21 ft at 31N 170W aimed east. The gale was gone after that. Small swell likely to result for Hawaii.

North CA: Dribbles fading on Sat (1/5) from 2.0 ft @ 12 secs (2.0-2.5 ft). Swell Direction: 280 degrees

 

North Dateline Gale
Another small gale developed
Tues AM (2/1) on the dateline with 50-55 kt west winds over a tiny area lifting northeast with seas building from 27 ft at 41.5N 178.5W aimed east. In the evening 45-50 kt winds were lifting northeast fast with seas 33 ft over a tiny area at 46N 172.5W aimed east. On Wed AM (2/2) the gale was moving over the Central Aleutians with 35-45 kt west winds and seas 35 ft at 50.5N 172.25W aimed east. The gale was gone after that. Minimal swell is possible.

Oahu: Swell fading on Sat (2/5) from 4.4 ft @ 13 secs (5.5 ft). Swell Direction: 310 degrees.

North CA: Expect swell arrival on Sun (2/6) building to 4.2 ft @ 13-14 secs early (5.5 ft). Residuals fading Mon (2/7) from 3.8 ft @ 12-13 secs early (4.5 ft). Swell Direction: 192 degrees

 

Northwestern Gulf Gale
On Wed PM (2/2) another small gale was building just west of the dateline with 45 kt west winds over a tiny area and seas building from 23 ft at 34.5N 172E aimed east. The gale was racing east-northeast on Thurs AM (2/3) with 45-50 kt west winds and seas 26 ft at 38N 176W aimed east. In the evening the gale lifted northeast with 55 kt west winds and seas 38 ft at 44N 168.25W aimed east. On Fri AM (2/4) the gale was approaching the Eastern Aleutians with 50 kts west winds and seas 38 ft at 48.75N 163.25W aimed east. In the evening the gale was fading over the East Aleutians with 35-40 kts west winds and seas 32 ft at 54.25N 159.25W aimed east.

MJO/ENSO Forecast

 

La Nina Evaporating - Kelvin Wave 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 Central 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.

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.

LONG-RANGE PACIFIC STORM AND SWELL GENERATION POTENTIAL FORECAST
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 (2/4) 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 light east 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 (2/5) moderate east anomalies were filling the KWGA. The 7 day forecast calls for east anomalies holding in coverage and strength at moderate status through the end of the model run on 2/12.

Kelvin Wave Generation Area wind monitoring model: West and East

MJO/WWB/Wind Projections:  
OLR Models: (2/4) A moderate Inactive MJO was indicated over the KWGA. The statistical model suggests it is to build some on day 5 of the model run holding on days 10 and 15 filling the KWGA. The dynamic model projects the Inactive Phase building to strong status on day 5 over the KWGA holding on day 10 and 15 still centered firmly in the KWGA.
Phase Diagrams 2 week forecast (ECMF and GEFS): (2/5) The statistical model depicts the Active Phase was weak over the Central Indian Ocean and is forecast slowly moving to the Maritime Continent and strength unchanged for the next 15 days. The dynamic model suggests Active Phase retrograding to the Central Indian Ocean in 3 days and at modest strength then pushing east to the West Maritime Continent at day 15 of the model run at moderate strength.
40 day Upper Level Model (assumed to be a statistical mode and 1 week ahead of what is occurring at the surface): (2/4) A weak Active MJO signal (wet air) was depicted over the Central Pacific today. The forecast indicates the Active Phase (wet air) steadily moving east tracking into Central America on 3/5. The Inactive Phase (dry air) is to be building over the West Pacific in earnest starting 2/18 at moderate strength filling the KWGA then tracking east moving to the East Pacific at the end of the model run on 3/16. No Active Phase (wet air) is to follow.
4 Week CFS Model (850 mb wind): (2/4) No MJO signal was depicted today but modest east anomalies were filling the KWGA. The forecast has east anomalies building in coverage and strength filling the KWGA at near strong status by 2/12 with the Inactive Phase building then filling the KWGA on 2/19 with strong east anomalies filling the KWGA through the end of the model run on 3/4 with the Inactive signal pushing east of the KWGA on 3/3.
3 Month CFS Model (850 mb wind): (2/5 - 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 peaking over the KWGA with weak east anomalies filling the KWGA. The forecast has east anomalies filling the KWGA peaking near 2/26 on the dateline as the Inactive Phase pushes east and then fully moves east of the KWGA on 3/5 with east anomalies fading fast then. On 2/7 a coherent Active Phase of the MJO is to start pushing east over the western KWGA but stalling, then finally pushing east filling it on 3/4 with west anomalies moving east from the Maritime Continent into the West KWGA on 3/1. The Active Phase is to hold over the KWGA through 3/31 with moderate west anomalies filling the KWGA starting 3/7 and holding into 4/10. The Inactive Phase is to develop 3/25 in the West KWGA tracking east through the end of the model run on 5/5 but 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 a bit east of the dateline with its western perimeter at 170E today moving to the dateline by 3/27 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 135E and barely in the KWGA but is forecast starting to move east further into the KWGA to 170E on 3/21 filling 75% of the KWGA and building further east quicker to nearly the dateline at the end of the model run on 4/29 as a second contour builds. Today a solid east anomaly pattern that had been in control of KWGA since early July is gone. A return to a more normal MJO alternating pattern is developing. And the low pressure bias is to start building over the dateline region in early 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 some sort of gale and swell production.

Subsurface Waters Temps
TAO Array: (2/5) Today in the far West Pacific the 29 degree isotherm was steady at 174E. The 28 deg isotherm line was steady at 176W. The 24 deg isotherm was easing east into Ecuador. Anomaly wise, warm anomalies +3 deg C were steady with their leading edge moving east to about 120W and showing signs of stalling there. Cool anomalies were fading at -1 degs C 75 meters down at 100W and tracking east. The hi-res GODAS animation posted 1/28 indicates a Kelvin Wave pushing east with 4-5 degs warm anomalies with its eastern edge at 120W with cool anomalies at -3 degs C 25 meters down and pushing to the surface at 90W while rapidly fading. The GODAS animation appears to be 1 week behind the TAO data but also is more detailed and accurately modeled.
Sea Level Anomalies: (1/28) Sea heights were negative over the East equatorial Pacific from Ecuador to 125W at -5 cms and losing coverage quickly. -10 cm anomalies were no longer present. But positive anomalies were steady, no longer creeping east locked at 140W. It appears a Kelvin Wave is stalled. 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 peaked in coverage in mid-Oct, then started rapidly collapsing while being pushed east. Warm water was fast moving east with it's leading edge today at 122W. It appears a Kelvin Wave is moving east, the first since last summer likely signaling 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: (2/4) The latest images depict a broad stream of cool water on the equator extending west from just off Ecuador peaking at 110W then weaker west of there to the dateline. The core of this pool is rapidly fading in intensity and coverage day by day. Its pretty amazing how quick the demise is occurring. The classic La Nina pattern is in quick retreat. There are signs of warming along the coasts of Chile and Peru. An area of warm water was holding just north of the equator across the entire North Pacific. Overall this indicates the demise of La Nina.
Hi-res 7 day Trend (2/4): Warming was occurring from Ecuador west on the equator to 160W. No cooling was evident. Warming was occurring off all of Chile and Peru too out to 120W.
Hi-res Overview: (2/4) The magnitude of the core of the La Nina cool pool is fading quickly if not collapsing. But weaker residual cool waters were still covering a large area from Peru up to the equator and west 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: (2/5) Today's temps were falling some to -1.269 after dropping to -1.421 on 1/29. Temps previously rose 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 rose to -1.432 on 11/29 and that after dropping 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. Before that temps were toggling around neutral 6/13-8/5 except for one dip to -0.411 on 7/8. Prior to that temps peaked on 3/16 when they briefly hit +0.714 degs. 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:
(2/5) Today's temps were falling slightly at -0.564 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 Uncorrected Data (2/5) - 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 -0.3 degs through Aug down to -1.05 degs in mid-Nov and holding. The forecast indicates temps slowly toggling upwards to -0.70 degs in Feb then falling to -1.05 degs in May only to resettle at -0.95 degs in the July and beyond. This is not believable. This model suggests we are at or almost past the peak of La Nina temperatures this Winter. But there is no indication that El Nino will develop and if anything we'll fall into a weak steady state La Nina beyond. The PDF Corrected forecast suggests the same as the uncorrected version. Still, neither of these forecasts seems realistic (see IRI Consensus forecast below).
IRI Consensus Plume: The Jan 13, 2022 Plume depicts temps are -0.960 degs today and have bottomed out. They are to warm to -0.586 degrees in March, then rising to -0.011 degs in July and neutral 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 (2/5) the daily index was positive at +13.35 after peaking at +46.71 on 12/26. The trend of late has been towards positive readings the past 16 days after trending negative the month before. Previous 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 at +4.71 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 rising at +9.59 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').
