 Based on OISST, Monday’s weekly RONI equivalent for this week averaged out should be warmer than the +0.2 of last week. I’m leaning to +0.4 but +0.5 is possible. Today’s RONI equivalent is ~+0.5-+0.6:

 

 

My leaning of the weekly relative 3.4 going up from +0.2 in last week’s release to +0.4 in today’s turned out to be what happened for its 4th rise in a row. Nino 1+2 cooled again (by 0.2) to +0.7. Nino 3, like Nino 3.4, rose for the 4th week in a row to +0.5. Nino 4 was unchanged at +0.5. So far, it’s not behaving as if it is headed to strongly E based this autumn. Cansips has been suggesting central to W based with E (1+2 to 3) not as warm as C to W (3.4 to 4), but we’ll see as there’s a long way to go:

Date (avg for wk centered on)………………....1+2………..3………..3.4………..4

 01APR2026         0.8       -0.3       -0.3        0.2
 08APR2026         1.1       -0.1       -0.2        0.3
 15APR2026         1.2        0.2        0.1        0.6
 22APR2026         0.9        0.3        0.2        0.5
 29APR2026         0.7        0.5        0.4        0.5

 The latest SSTa charts suggest a pause, which is long overdue, MAY finally be occurring temporarily:

Pretty impressive to see the upper ocean heat anomalies this week higher than at any point during the 2023-2024 and 2015-2016 events. 
 

 

I would like to see how this actually translates to surface readout coming up.
