PACIFIC OVERVIEW
Current Conditions
On Thursday (5/19) North and Central CA had set waves at chest to shoulder high and soft and warbled with whitecaps present early. Protected breaks were chest to shoulder high and lined up and a bit closed out from low tide and relatively clean with some warble intermixed. At Santa Cruz surf was waist to chest high on the sets and clean and somewhat lined up but mostly soft. In Southern California/Ventura waves were waist to chest high and decently lined up but weak and soft and mushed but clean with no wind. Central Orange County had sets at chest high on the sets and lined up with decent form but wit a little warbled intermixed from light south wind. South Orange County's best summertime breaks had set to chest high on the peak and fairly line dup but soft with clean conditions. North San Diego had sets to chest high and lined up and clean but a little closed out from low tide. Hawaii's North Shore had a few waist high sets at top breaks and clean. The South Shore was waist to chest high and warbled if not nearly chopped from south wind. The East Shore was getting knee high east windswell and fairly clean with light south wind.

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

Meteorological Overview
On Thursday (5/17) California was getting typical summertime northwest windswell at exposed breaks with some minimal southern hemi swell occasionally showing at south facing break. Hawaii was getting limited southern hemi swell but marred by south wind.

A gale formed in the Central South Pacific on Tues (5/10) with 37 ft seas aimed well northeast then pushed east through Thurs (5/12) with up to 36 ft seas aimed east to northeast. That swell is hitting Hawaii and California. Beyond a gale formed over the Central South Pacific Tues-Wed (5/18) producing 32 ft seas aimed northeast. Small swell is starting to radiate towards the US West Coast. And another is to form under New Zealand moving northeast just off the coast there Fri-Sun (5/22) producing up to 35 ft seas aimed well north. And maybe another to follow in the same area Mon-Wed (5/25) producing 26-35 ft seas aimed well northeast. So some hope is on the charts.

South Pacific

Overview
Jetstream
On Tuesday (5/17) the influential southern branch of the jet was lifting northeast from under New Zealand with winds only 100 kts forming a trough over the South Central Pacific offering some limited support for gale development. Over the next 72 hours the New Zealand trough is to slowly track east while holding together reaching the East Pacific on Thurs (5/19) and weaker perhaps offering some limited more support for gale development. But a ridge is to be building over the Southwest Pacific on Wed (5/18) suppressing support for gale development and pushing east. Beyond 72 hours starting Fri (5/20) a new trough is to start building under New Zealand on Fri (5/20) being fed by 110 kts winds offering some support for gale development and being reinforced on Sun (5/22) with winds to 140 kts offering better support for gale development. And yet more wind energy is to be building lifting north under new Zealand on Tues (5/24) at 140 kts really carving the trough out well offering good support for gale development. Certainly an improving pattern is suggested.

Surface Analysis
Swell from a gale that developed over the Central South Pacific is hitting Hawaii and California today, but weak (see Central South Pacific Gale below). Swell from another gale that formed over the Central South Pacific is just starting to propagate northeastward from its source (see Another Central South Pacific Gale below).

Over the next 72 hours a new gale is to form south of New Zealand on Fri AM (5/20) with 40-45 kts south winds and seas building. In the evening south to southwest winds to be 40-45 kts solid just south-southeast of New Zealand with 33 ft at 52.75S 169.25E aimed northeast. On Sat AM (5/21) southwest winds to be 40-45 kts just southeast of New Zealand producing 34 ft at 50.5S 175.75E aimed northeast. In the evening fetch is to start pushing east at 40+ kts over a solid area with seas 35 ft at 45.25S 173W aimed northeast. On Sun AM (5/22) winds to turn more easterly at 35-40 kts with seas 33 ft at 51.25S 164.75W aimed northeast. In the evening fetch is to be fading from 30-35 kts from the east with seas 32 ft at 53.75S 156W aimed east. Something to monitor.

Central South Pacific Gale
Mon PM (5/9) a small storm developed southeast of New Zealand with 50-55 kt south winds and seas 30 ft at 61S 170W aimed northeast. On Tues AM (5/10) the gale had 45+ kt southwest winds lifting northeast with seas 37 ft at 55.75S 162W aimed northeast. In the evening the gale was pushing northeast with 35-40 kt southwest winds and seas 32 ft at 53.5S 152.75W aimed northeast. The gale pushed east Wed AM (5/11) over the Southeast Pacific with 45 kt west-southwest winds and seas 33 ft over a tiny area at 55S 140.75W aimed northeast. In the evening fetch was pushing east at 35-40 kts with seas 30 ft at 54.5S 129.25W aimed east and on the east edge of the SCal swell window. Secondary fetch was pushing over the same area on Thurs AM (5/12) from the west at 40 kts with seas 31 ft at 49.75S 137.5W aimed east. In the evening 40 kts west winds were pushing to the edge of the SCal swell window with seas 31 ft at 49.25S 126.25W aimed east. This system was east of the SCal swell window beyond.

Hawaii: On Thurs (5/19) swells at 1.8 ft @ 13 secs (2.0-2.5 ft) and 1.6 ft @ 15-16 secs (2.5 ft). On Fri (5/20) swell steady at 2.0 ft @ 14 secs (2.5-3.0 ft). Residuals on Sat (5/21) fading from 1.7 ft @ 12 secs (2.0 ft). A final pulse to be fading on Sun (5/22) from 1.5 ft @ 14-15 secs (2.0 ft). Dribbles on Mon (5/23) fading from 1.5 ft @ 13-14 secs (2.0 ft). Swell Direction: 185-190 degrees

Southern CA: Another pulse to arrive on Thurs (5/19) at 1.8 ft @ 16-17 secs (3.0 ft). Swell holding on Fri (5/20) at 2.1 ft @ 15-16 secs (3.0-3.5 ft). Swell continues Fri (5/21) at 2.1 ft @ 14-15 secs (3.0 ft). Residuals on Sat (5/22) fading from 1.8 ft @ 14 secs (2.5 ft). Swell fading Sun (5/23) from 1.8 ft @ 13-14 secs (2.0-2.5 ft).

Swell Direction: 184-194 degrees

Another Central South Pacific Gale
A gale formed in the South Central Pacific on Mon PM (5/16) producing a modest sized area of 40-45 kt south winds with seas building from 30 ft at 59.5S 159.5W aimed northeast. On Tues AM (5/17) southwest winds were growing in coverage at 35-40 kts with seas 27 ft over a moderate area at 55S 152W aimed northeast. In the evening southwest winds rebuilt to 40-45 kts solid moving to the Southeast Pacific with seas 32 ft at 55.75S 148W aimed northeast. On Wed AM (5/18) fetch pushed east at 35-40 kts from the southwest with seas 30 ft at 53S 135.25W aimed northeast. Fetch pushed northeast in the evening while fading from 30-35 kts from the southwest and seas fading from 28 ft at at 51.75S 126W. The gale was east of the Southeast CA swell window after that. No swell is to result for Hawaii with all energy focused on the US West Coast and more so for Central America.

Southern CA: Expect swell arrival on Thurs (5/26) building to 1.6 ft @ 16-17 secs mid day (2.5 ft). Swell building on Fri (5/27) to 2.1 ft @ 15 secs later (3.0 ft). Swell continues on Sat (5/28) at 2,0 ft @ 15 secs (3.0 ft). Swell fading Sun (5/29) from 2.0 ft @ 13-14 secs (2.5-3.0 ft). Swell Direction: 195 degrees

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

North Pacific

Beyond 72 hours the model suggest a gale forming off North Japan half way to the dateline on Tues (5/24) producing 35 kt northwest winds and up to 20 ft sea over a small area at 38.8N 165.75E aimed well at Hawaii. Odds of this actually occurring are remote.

Otherwise no swell producing weather systems of interest are forecast.

South Pacific

Beyond 72 hours a new fetch of southwest winds at 40-45 kts is to develop south of New Zealand on Sun PM (5/22) Mon PM (5/23) getting traction and generating seas of 29 ft at 57.5S 166E aimed northeast. On Mon AM 45-50 kt southwest winds are forecast over a small area aimed northeast with seas 35 ft at 53.75S 178.25E aimed northeast. In the evening southwest winds to be 40 kts over a fading area with seas 32 ft at 50.75S 169.5W aimed east-northeast.

On Tues AM (5/24) a secondary fetch of south winds are to build under New Zealand with 30 ft seas at 52S 165.75E aimed northeast. in the evening fetch is to build and move clear of South New Zealand to the east at 35-40 kts over a broad area with seas 31 ft at 47.25S 178.25E aimed northeast. Fetch is to be fading Wed AM (5/25) from 30-35 kts over a broad area with seas 27-28 ft at 47.25S 174.25W aimed northeast. Fetch gone after that. More hope.

MJO/ENSO Forecast

CFS Model Upgrades
Weak La Nina through Fall then Fading - SOI Peaked Late April - New Kelvin Wave Stalled
Summary - Cool subsurface water volume peaked under the equatorial Pacific on 10/15/21 and is now fading. But the SOI is peaking just now, higher than last years peak. A delayed response. A much hoped for Active Phase of the MJO (and westerly anomalies) in April has resulted in a weak Kelvin Wave but it is stalled mid-way across the Pacific today. It seemed the peak of La Nina was behind us. But La Nina conditions are projected by the CFS model until Nov, then fading, suggesting an uncertain future. West anomalies are forecast filling half the KWGA from here forward. The outlook is unclear but seems like ENSO neutral is trying to set up.

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 (5/18) 5 day average winds were strong from the east over the Eastern equatorial Pacific and strong east over the Central Pacific fading to modest east over the KWGA. Anomalies were neutral over the East equatorial Pacific and neutral over the Central Pacific and neutral 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 (5/19) mostly weak east anomalies were over the KWGA. The 7 day forecast calls for east anomalies building over the KWGA to moderate status on 5/22-5/24 then fading some while moving almost east of the dateline at the end of the model run on 5/26.

Subsurface Waters Temps
TAO Array: (5/19) Today in the far West Pacific the 29 degree isotherm was present at 166E moving from 161E previously. The 28 deg isotherm line was easing east to 177E (previously 175E). The 26 degree isotherm backtracked from 120W to 135W to 141W on 5/3 and is easing east now back to 131W today. The 24 deg isotherm was steady across the East Pacific. Anomaly wise, warm anomalies +3 deg C were in a pocket in the far West Pacific down 150m with it's leading edge easing east to 137W with a thin stream connecting it to the East Pacific. A previous pool of -1C cool anomalies below the warm pool at 100W are now gone. The hi-res GODAS animation posted 5/13 indicates the same pocket of cool anomalies between 120W-80W at -3 degs C and appears to be now be shifting east and weakening. A new Kelvin Wave is starting to push east from the West Pacific, stalled about late April, but now is moving east to 138W. The GODAS animation appears to be 1 week behind the TAO data but also is more detailed and accurately modeled.
Sea Level Anomalies: (5/13) Sea heights were steady over the Equatorial Pacific. A string of weakly positive anomaly pockets were north of the equator pushing from the dateline to 100W along the 5N latitude line and holding with pockets at +5 cms with one to +10 cms. A broad but shrinking area of negative anomalies at -5 cms were over the equator from Ecuador to 135W with -10 cms between 85W-105W. Otherwise positive anomalies were mostly locked from the dateline and points west of there. Per the Upper Ocean Heat Anomaly Histogram a pocket of cool anomalies was fading from -1.0 degs between Ecuador and 117W and shrinking. And a new Kelvin Wave is trying to push east from 152W. So it looks like the most recent cool bout was just the upwelling phase of the Kelvin Wave cycle and a new downwelling Kelvin Wave is developing while pushing east, but weak and possibly stalled.

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: (5/18) The latest images depict a broad generic pool of cool water extending west from Ecuador to the dateline extending well south of the equator. Only a few lingering pockets of warm water remained on the equator from Ecuador to 130W. A pocket of previously stronger cold water was fading along the coast of Peru reaching to the Galapagos on the equator and losing density and coverage fast and almost gone. A weak area of warm water was present north of the equator (1 deg N) across the entire North Pacific. Overall this indicates the late stages of La Nina.
Hi-res 7 day Trend (5/18): A thin string of warming water were from the Galapagos over the width of the equator to the far West Pacific. Warming was also starting to build along the coast of Peru weakly and thinly.
Hi-res Overview: (5/18) Persistent cool waters cover a large area from Ecuador to 160E on the equator and from South America down at 20S. Warmer than normal waters were aligned from 1N and above over the entire North Pacific. La Nina remains in control over the East Equatorial Pacific.
Nino1.2 Daily CDAS Index Temps: (5/19) Today's temps were rising at -1.626 previously down to -2.057 on 4/23 and had been near there since 4/19. Prior to that they were fading after peaking at +0.760 on 3/18. Temps had been moving upwards since 2/20, and beat 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: (5/19) Today's temps were rising slightly to -0.882 have previously been at -0.929 since 5/2 and that after rising to a peak at -0.704 on 3/27 and had been on a gentle rising trend since falling to -1.012 on 3/8. Previously temp were 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 then fading to -1.1 degs in May.
Forecast (5/18) - Temps are to steadily rise moving forward to about -0.45 degs in July falling to -0.80 into Nov, then rising to the La Nina threshold in Jan at -0.5 degrees and up to -0.25 degs in Feb. This model suggests we are at going to slowly transition towards ENSO neutral in the coming Winter. The PDF Corrected forecast suggests temps rising to -0.25 degs in July then slowly falling to -0.65 degs in Nov, then rising to -0.50 degs in Jan and to -0.20 degs in Feb. This is starting to come in line with the IRI forecast (see IRI Consensus forecast below).
IRI Consensus Plume: The April 18, 2022 Plume depicts temps are -0.705 degs today and have bottomed out. They are to warm to -0.601 degs in May (previously -0.315 degrees last month), then rising to -0.449 in July (previously -0.287 degs) and hovering there through November then rising to -0.351 degs (previously 0.0 degs) after that. This model now suggest a continuation of weak La Nina conditions through the Fall.

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 (5/19) the daily index was positive at +13.19 degs today and up to +40.77 on 5/10 previously peaking at +31.44 on 4/27, +31.80 on 4/6, +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 falling some to 19.59 today after rising to +20.34 (5/12) the highest in a year and beating last years high of +19.51 on 1/14.
The 90 day average was rising some at +15.80 today the highest in a year. It previously peaked 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 2/23/21 (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').
