2026-2027 Super El Nino

I’m educatedly guessing that the weekly relative Nino 3.4 will rise from last Monday’s +1.2 to +1.4 in today’s release. I’m guessing 1+2 will be in the +2.7 to +2.8 range. These weeklies are OISST based.

 Nino 1+2 came in at +2.6 vs my guess of +2.7 to +2.8.

 Nino 3.4 rose only from +1.2 to +1.3 vs my guess of a rise to +1.4. The daily relative 3.4 OISST graph (see below) had suggested a rise of 0.2 rather than 0.1. Perhaps the rise was just under 0.15 and this rounded down to a rise of 0.1?

 But also, the image below of relative OISST for 3.4 suggests the relative 3.4 for last week (7/5-7/11 or the last 7 dots) was actually ~+1.5 (actually a little warmer than +1.5). So what’s going on? How come NOAA had it at only +1.3 being that they state it is OISST based? The +1.3 and this chart don’t jibe:

 

01JUL2026         2.7        1.5        1.2        0.5
 08JUL2026         2.6        1.7        1.3        0.5

We likely see a sizable jump come with next Monday’s update based on the ongoing warming in 1+2 and 3.4. I actually expected region 4 to come in around +0.4C as the SST charts were showing a cooling there. That is definitely one difference from previous recent Ninos where we saw region 4 way above average with consistent warming each week. Anyway, the models are already keying in on yet another WWB

Thanks, Adam.

It appears that Zeke’s using ONI based climo comparisons. If he were to instead use RONI, it would still be the warmest on record but not by as much as the 0.8C that he refers to. So, it would be an easy record breaker even by RONI standards.

Agreed.

 We’re probably heading to a new warmest OHC of this Nino per this (often the far right portion of these graphs is later revised due to interpolation…so it isn’t certain yet):

The big question is, does the +ENSO signal become so strong by winter that its forcing overwhelms it in the seasonal mean? Do we start to see the -PDO finally reverse?

The northern tier trough signal was more apparent looking at the past 30 days. Focused in the middle of the country.

Don’t  the messenger:  I’d like to see, if possible, and if it doesn’t take forever to find out if this JFM really is the coldest ever forecasted going back to 2012. Is it worth my valuable time? Probably not. What do y’all think about this map, which is a mean of a whopping 10 days of runs of its ensemble as opposed to just one run?
