El Niño latest

The coastal waters off the coast of Chile seem to have cooled down since last month. There were SST anomalies 0f +5°C on the chart for the 18th of March last month (fig 1), but the highest that I can see in the same area is +3°C twenty five days later (fig 2). The experts are saying that an El Niño event still remains a distinct possibility towards the end of this year though.

I’m no expert and don’t pretend to understand why the cold Humboldt current seems to be the controlling mechanism for the upwelling of warmer water off the coast of Chile (fig 3).

But this map I found after a little research on the Internet indicate that there are more than just the Humboldt current at play down the coast of South America (fig 4).

I shall of course try to find out and report back, unless one of my readers would like to do it for me.
