Using weekly sea surface temperature anomalies for the NINO3.4, and NINO 1+2 regions, these charts update and expand on the comparisons of the evolutions of this El Niño with the 1982/83 and 1997/98 events. . NINO 3.4  region sea surface temperature anomalies this year are still in the ballpark of the two earlier strong El Niños. And in the NINO 1+2 region, the temperature anomalies have broken away sharply from the 1982/83 El Niño evolution, but they’re still far below the values at this time for 1997/98 El Niño. We’ll have to keep an eye on the NINO 1+2 data, because they’re an indicator of an East Pacific El Niño, which are stronger than Central Pacific El Niños.
