2026-2027 Super El Nino

[raindancewx]

Locally we tend to see more robust monsoon precipitation, advancement and development when the snow pack is destroyed early in the season. At the automated snow measurement site on Ski Taos at 11,000 feet above sea level, we had ~40 inches of snowpack left on 5/23/23. In 2026, that was the day the snowpack fully melted. Would prefer not to relive July 2023, as it's essentially as warm as it can get here due to the complete lack of rain in our wettest month. I believe its our warmest month on record.

Fortunately the source of the July 2023 heatwave here was the June 2023 heatwave in Mexico, which is not present. The El Nino developing still looks pretty different from 2023-24.  My records from June 2023 show towns even at 8,000+ in elevation in Central Mexico were running over 90 degrees for highs, v. typical readings in the low 70s. Some of those same towns have had rain-cooled highs in the 60s already this month.

June is typically not a big month for ENSO to effect the N. Hemisphere pattern, but we continue to see differences in the North Pacific

Isn’t the pattern around day 10 close to the normal +enso June look though?

We get a little low south of the Aleutians Days 5-9. Around Day 10 a ridge is building into the Gulf of Alaska. I guess you can say that's close, but a slight difference west makes it more -PNA. 

I'm just really looking at the PNA, June will likely be the 5th consecutive month of -pna, and the average is no joke, it's less than -1/month

1965, 1982, and 2023 all had a 4-month streak of -PNA that were broken in June. 

[Stormchaserchuck1]

June PNA will likely finish <-1, but it doesn't have a high correlation to the Winter, surprisingly

The EPAC has come alive….invests/convection galore. I think this has a very good chance of being a historic TC season in the EPAC

November 2026 hasn’t occurred yet. So this past November was in 2025.

Part of the reason this El Niño is becoming record breaking so early on is due to the accumulation of record SST warmth in the WPAC. The WWBs beginning in November 2025 started the kelvin waves and warm push eastward.

These are record breaking WWBs that we haven’t seen since the late 1990s. So a record WPAC warm pool initiation plus record WWBs equal a record El Niño.

Also note how Nino 1+2 never fully cooled off after the last super El Niño in 2023-2024. So it’s no surprise that this event is becoming so strong given the much warmer background state that it’s originating in.

Past climate reconstructions along with modeling support the hypothesis that it’s normal for El Niños to become more frequent and stronger as the world warms. So the 2020s will be the first decade with super El Niños over +2.0° occurring only 3 years apart.

Plus recent studies show that at some point in the future we can warm enough to enter a sustained El Niño climate. But we really don’t know the global temperature threshold at which this could theoretically occur.

Still uncertain if this could even occur in a modern warmer climate or the stronger and more frequent El Niño mode continues to dominate over some La Niña intervals in between.

Yeah but the maps of Austrailia are from 2025,not 2026,its not as warm as those are showing,just saying
