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/Utility Class: 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.
Surf Heights for Hawaii should be consider 'Hawaiian Scale' if period exceeds 14 secs.
On Sunday (8/29) North and Central CA had waves at waist hi or so and mushed with a fair amount of warble from light northwest winds with overcast early. Protected breaks had chest to shoulder high sets and soft but lined up and clean. At Santa Cruz surf was thigh to maybe waist high on the rare sets and weak and short but clean and inconsistent. In Southern California/Ventura waves were thigh high and slightly warbled with light northwest wind. Central Orange County had set waves at waist high or so and weak and soft with clean conditions and a steady light northerly breeze. South Orange County's best summertime breaks had sets at waist high and somewhat lined up and clean but with fog in control. North San Diego had sets waves at waist high plus on the peak and lined up and clean but with lump running through it and soft and foggy early. Hawaii's North Shore was flat and clean. The South Shore was getting some minimal waves with sets at waist high or so and lined up and clean. The East Shore was flat and heavily textured from modest east trades.
See QuikCASTs for the 5 day surf overview or read below for the detailed view.
On Sunday (8/29) no swell of interest was hitting either Hawaii or California with local windswell being the only swell source and that limited to exposed breaks in North and Central CA. Currently small swell is radiating north originating from a gale that developed southeast of New Zealand on Thurs-Sun (8/29) producing 29 ft seas aimed east while traversing the South Pacific. Beyond that nothing is forecast. And nothing is forecast in the NPac either. It's either windswell or nothing until the minimal southern hemi swell arrives.

On Sunday (8/29) the influential southern branch of the jet was pushing north from under New Zealand being fed by 100 kt winds forming a weak trough southeast of New Zealand reaching up to 52S and over ice free waters offering some minimal support for low pressure development. From there the jetstream held at about 55S the rest of the way east across the South Pacific perhaps offering some limited support for low pressure development. Over the next 72 hours that trough is to slowly track east while weakening with a solid ridge pushing south down to 73S moving from under New Zealand to the Central South Pacific through Wed (9/1). But wind energy in the leading edge of the ridge is to build to 150 kts lifting north on Wed (9/1) forming a trough over the Southeast Pacific offering some support for gale development. Beyond 72 hours that trough is to sweep east and out of the Southern CA swell window on Thurs (9/2) leaving the ridge in control of the entirety of the South Pacific then and offering no support for gale development. No change is forecast until Sat (9/4) when the ridge is to start lifting north over the Central South Pacific starting to form a broad trough on Sun (9/5) perhaps offering some support for gale development there.
On Sunday (8/29) small swell was radiating north originating from a gale that traversed the South Pacific (see South Pacific Gale below).
Over the next 72 hours no swell producing weather systems of interest are forecast.

La Nina Slowly Rebuilding
Summary - Cool water is building across the subsurface equatorial Pacific with warm water from previous Kelvin Waves fading and present only just off Ecuador. The forecast has improved some though suggesting only a short lived high pressure bias controlling the dateline in early Fall then turning neutral. Still it seems blocking high pressure is to hold over the Gulf of Alaska through early Winter 2021-2022.
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.
LONG-RANGE PACIFIC STORM AND SWELL GENERATION POTENTIAL FORECAST
Spring/Summer 2021 = 4.0/3.5 (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 is assumed that the moderate La Nina from the Winter of 2020/2021 is on the wane and that a return to neutral ENSO state will set up over the Pacific Basin through the summer of 2021. But lingering effects of La Nina are forecast to continue over the Pacific for some time as the upper atmospheric circulation slowly transitions to an ENSO neutral state. This scenario tend to favor the Southeast Pacific, therefore favoring California over Hawaii. To counter that is the forecasted movement of the low pressure bias currently in-flight from the Maritime Continent to the West Pacific over the next 3 months. Still it will take some time for the atmosphere to fully respond, resulting in a slightly less than normal swell production forecast. A somewhat reduced number of storm days and storm intensity is expected as compared to normal over the South Pacific during the early summer season, resulting in a below normal level of swells, with swell being below normal duration and period. But by the Fall and early Winter of 2021/22, 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 (8/28) 5 day average winds were strong from the east over the Eastern equatorial Pacific then modest east over the Central Pacific and moderate east over the KWGA. Anomalies were light easterly over the East equatorial Pacific and light west 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 (8/29) east anomalies were moderate filling the KWGA. The forecast calls for east anomalies holding at moderate strength filling the KWGA for the next week through the end of the model run on 9/5 and expanding east filling the entire equatorial Pacific by 9/2 and holding. No sign of the Active Phase of the MJO is forecast.
Kelvin Wave Generation Area wind monitoring model: West and East
- MJO/WWB/Wind Projections:
OLR Models: (8/28) A modest Inactive MJO signal was indicated over the KWGA today. The statistic model projects an Inactive pattern rebuilding some on day 5 of the model reaching moderate strength and holding on day 10 and 15 of the model run. The dynamic model projects the Inactive Phase holding at modest strength on day 5 of the model run then fading to near neutral on day 10 and weaker still on day 15. the 2 models are projecting opposite outcomes.
Phase Diagrams 2 week forecast (ECMF and GEFS): (8/29) The statistical model depicts the Active Phase was weak over the Central Indian Ocean and forecast tracking east to the Central Maritime Continent at very weak status 15 days out. The dynamic model suggests the Active Phase pushing slowly east to the East Indian Ocean on day 15 of the model run at weak status.
40 day Upper Level Model (assumed to be a statistical mode and 1 week ahead of what is occurring at the surface): (8/28) A moderate Inactive Phase (dry air) was indicated over the Central and East Equatorial Pacific today. The Inactive Phase (dry air) is to push east and into Central America on 9/12 as a weak Active Phase (wet air) is forecast developing over the KWGA at the same time tracking east and weakly filling the equatorial Pacific by 9/17 then moving to the East Pacific at the end of the model run on 10/7. At that time a Inactive pattern (dry air) is to set up over the KWGA.
4 Week CFS Model (850 mb wind): (8/28) This model depicts a neutral MJO pattern over the KWGA today but with weak to modest east anomalies in control of the KWGA. The forecast indicates east anomalies filling the KWGA the end of the model run on 9/25 building to moderate strength centered on the dateline 9/11 through the end of the model run and unwavering. No coherent MJO signal is indicated in the Pacific for the duration of the model run.
3 Month CFS Model (850 mb wind): (8/29 - using the 5th ensemble member): Today a weak Inactive Phase of the MJO was fading over the KWGA with modest east anomalies filling the KWGA. The forecast indicates the Inactive Phase is to slowly push east and out of the KWGA on 9/24 with east anomalies at modest strength holding over the KWGA through that time. A solid Active Phase is to develop while slowly pushing east starting 9/22 taking over the KWGA on 9/30 and holding through 11/25 with west anomalies steadily plodding east filling the KWGA by 10/16 and holding through the end of the model run on 11/27. A moderate Inactive MJO pattern is to push into the KWGA on 10/25 slowly pushing east and nearly filling the KWGA at the end of the model run but with light west anomalies still in control over the KWGA. The low pass filter indicates a high pressure bias lost control of the area south of California on 8/28 (with one contour line) and the low pressure bias was gone too. A neutral bias was in control. But the high pressure bias is to return backbuilding on the dateline on 9/7 holding that position filling the eastern portion of the KWGA through the end of the model run and building with a second contour line developing on 9/31 then fading on 11/15. A broad single contour low pressure bias is to develop 10/5 recentered over the Maritime Continent at 100E holding through the end of the model run. East anomalies that have taken over the KWGA and are to slowly get shoved east as the Active Phase and west anomalies take over the KWGA mid October. This suggests a redevelopment of La Nina as we move into Fall but then that fading later in Fall as Winter starts to build.

Subsurface Waters Temps
TAO Array: (8/29) Today in the far West Pacific the 29 degree isotherm was pushing east to 177E. The 28 deg isotherm line was steady at 171W. The 24 deg isotherm pushed east to 120W from 130W. Warm water has receded west and has stabilized there. Anomaly wise, warm anomalies +1-2 deg C were building in coverage in the far West Pacific pushing east to 150W. East of there mostly cool anomalies were in control at 1 deg below normal from 150 meters down up to 75 meters down in the east. No Kelvin Waves were obvious and cool water was building in the east at depth. The hi-res GODAS animation posted 8/21 was much the same suggesting no warm water east of 160W. A solid stream of cool water was pushing up from 150 meters down there and breaching the surface just at the Galapagos. The GODAS animation appears to be 1 week behind the TAO data but also is more detailed and accurately modeled.
Sea Level Anomalies: (8/21) Sea heights were falling over the entire equatorial Pacific with negative anomalies at -5 to -10 cms over the East equatorial Pacific between Ecuador to 160W. All positive anomalies were limited from 165W and points west of there. A warm water 'horseshoe' pattern was redeveloping in the West Pacific. La Nina is making a return.
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.
Hi-res Nino1.2 & 3.4 Qualitative Analysis: (8/28) The latest images depict a steady stream of cool water has now developed on the equator from Ecuador west to the dateline. Markedly cooler water was in waves between the Galapagos to 150W. Cooling was developing along Chile and Peru. A broken area of warm water was along Central America up to Southern Baja. Overall this seems to indicate the return of cooling water temps and La Nina.
Hi-res 7 day Trend (8/28): A broad and dense stream of cooling water temps was filling the area from Ecuador to 115W. No significant warming was indicated except in pockets between 120W to 150W.
Hi-res Overview: (8/28) A thin stream of cooler than normal water was aligned on the equator from Ecuador to the dateline. Warmer than normal waters were limited to a line north of the equator up to Mexico. The clear cool outflow that has been in place pushing from California southwest to the a point over Hawaii's Big Island is stable but weak. La Nina appears to be trying to make a resurgence an the equator but fading north of there.
Nino1.2 Daily CDAS Index Temps: (8/29) Today's temps were falling at -0.681 and were down at -0.716 on 8/15. Before that temps were toggling around neutral 6/13-8/5 except for one dip to -0.411 on 7/8. Period to that temps peaked on 3/16 when they briefly hit +0.714 degs. The longterm trend has been towards falling back into negative territory.
Nino 3.4 Daily CDAS Index Temps: (8/29) Today temps were stable at -0.237 after falling to -0.370 on 8/22, the bottom of a downward trend that continued for the previous 7 weeks. Previously temps peaked 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.
CFSV2 Forecast for Nino3.4 Sea Surface Temp (SST) Anomalies & Current SST Anomalies
SST Anomaly Projections
CFSv2 Uncorrected Data (8/29) - Actuals per the model indicate temps were rising in early Nov 2020 after bottoming out at -1.25 degs, building to -0.01 degs in mid-June then starting a slow fade from -0.3 degs in early Aug. The forecast indicates temps continuing a slow fade into mid November dropping to -1.20 degs then starting to slowly rise to -1.00 degs in mid Jan 2022 pushing up to +0.00 degs in mid April 2022. This model suggests a return of La Nina conditions this Fall and Winter. There is no indication that El Nino will develop. The PDF Corrected forecast suggests temp falling to -1.00 degs in Nov starting to rise slowly in Jan 2022.
IRI Consensus Plume: The Aug 20, 2021 Plume depicts temps are at -0.41 degs today, and are to fade steadily to -0.57 degrees in Oct holding into Nov, then rising to -0.33 degs in Jan and neutral in March 2022. A weak return of La Nina is expected this Fall and Winter 2021-2022.

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) (8/29): The daily index was at +13.59 after peaking at +37.86 on 7/15. The 30 day average was falling to +3.02 after rising to +16.49 on 7/29 after falling to -3.36 on 6/22, the lowest in a year and beating the previous low on 6/14 of -2.08. It peaked at +19.51 on 1/14. The 90 day average was rising to +6.54 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.
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 every 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). Looking at the long term record, it is premature to conclude that we have in-fact turned from the negative phase (La Nina 'like') to the positive phase (El Nino 'like'). If anything it appears more likely we are still in the cool phase of the PDO.
