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
