The subsurface has warmed significantly over the past few months. That's +4c in the central-ENSO-subsurface. TAO/Triton is a little more conservative in their readings than CPC, and it still has a >+4c area in the western subsurface I went through, since data became available in 1985, and found the 10 top analogs to broad subsurface state in January-February, like we have now. There are 5 positive analogs, 5 negative analogs. It should be noted that a lot of analogs had a warm/cold western part vs a cold/warm eastern part, in contrast, and I didn't use those, I only did the whole subsurface based warm or cold. Jan-Feb 2026 so far -1) 2025 -- This later in the year was ENSO Neutral (0-1-0), with the ONI peaking at -0.5c, but not for 5 consecutive months. The RONI in 26-27 was Weak-La Nina, -1.0c +1) 2023 -- This later was a Strong El Nino (1-1-0), ONI peaking at +2.1c, RONI peaking at +1.5c +2) 2015 -- This later was a Strong El Nino (2-1-0), ONI peaking at +2.8c! RONI peaking at +2.4c +3) 2014 -- This later was a Weak El Nino (3-1-0), ONI peaking at +0.8c, RONI peaking at +0.6c -2) 2007 -- This later was a Strong La Nina (4-1-0), ONI peaking at -1.6c. RONI peaking at -1.6c +4) 2002 -- This later was a Moderate El Nino (5-1-0), ONI peaking at +1.3c. RONI peaking at +1.5c -3) 1999 -- This later was a Strong La Nina (6-1-0), ONI peaking at -1.7c. RONI peaking at -1.7c +5) 1998 -- This later was a Strong El Nino (7-1-0), ONI peaking at +2.4c. RONI peaking at +2.4c -4) 1994 -- This later was a Moderate El Nino (7-1-1), ONI peaking at +1.1c. RONI peaking at +1.4c -5) 1988 -- This later was a Strong La Nina (8-1-1), ONI peaking at -1.8c. RONI peaking at -1.9c So out of the hand-picked 10 best analogs of the past 40 years, 8/10 (80%) became the same ENSO state (warm subsurface to El Nino, cold subsurface to La Nina), 1/10 (10%) was Neutral the next year, and 1/10 (10%) was opposite. The total cumulative ONI peak for the 10 top analogs since 1985, was +13.9c, an average of +1.39c per year (Moderate ENSO state). CPC in January gave these probabilities I now see the RONI is linked on the CPC page. Very good! (Edited analogs above -- the RONI is good because it neutralizes the global warming skew, where ENSO has warmed on average about 0.2-0.3c vs historical) Climate Prediction Center - Relative Oceanic Niño Index (RONI) Mid January IRI models forecast. I will edit these if someone links more recent forecasts. Since 1994, only 7/31 ENSO years have been Neutral, per RONI. 24/31 have either been La Nina or El Nino. Since 1994, only 7/31 ENSO years have been Neutral, per ONI. 24/31 have either been La Nina or El Nino. Per RONI, 5 of the last 6 years (20-26) have been La Nina. Per RONI, 7 of the last 10 years (16-26) have been La Nina. Per RONI, 11 of the last 19 years (07-26) have been La Nina. Per RONI, 15 of the last 28 years (98-26) have been La Nina. That's >50% La Nina since 1998. You can see this post-1998 general La Nina pattern clearly in the Northern and Southern Hemisphere's Hadley Cell, High pressure right above and below Nino 3.4: ^People say it's a decadal PDO state, I think it's a decadal cold-ENSO state. That map encompasses the most recent 333 months.
