We are talking about a temperature difference here of something less
than a degree Centigrade:
From Earth Observatory:
La Niņa, the counterpart to El Niņo, alters rainfall patterns over the
Pacific and Indian Ocean basins.
La Niņa develops when stronger-than-average trade winds push the warm
surface waters of the equatorial Pacific west. Since cold water rises
to replace the warm water, La Niņa leaves the eastern and central
Pacific Ocean much cooler than normal, while the western Pacific is
much warmer than normal.
These anomalies in sea surface temperature are mirrored in rainfall
patterns, with warmer-than-normal temperatures resulting in enhanced
rainfall. In general, La Niņa brings unusually heavy rain to the West
Pacific, Indonesia, parts of South east Asia, and northern Australia.

Please note the near-surface current that flows from the N. Pacific,
across Indonesia, into the Indian Ocean.

Please note how near Peru this convective current gets. Venezuela.
What is that recalcitrant scion of democracy up to there I wonder. I
doubt he has much influence on a certain moneycrazy.
No matter what its chimp says.
Whatever the case the fact remains that the temperature difference is
only a fraction of one degree centigrade.
It is customary to link weather events in either hemisphere with the
currents of the surface water over which they flow.
Rightly or wrongly any egress of the Peruvian current across the
equatorial counter current leaves a lot to be desired in reference to
its effect on massive weather systems in the northern hemisphere.
Their root causes however, are a completely different thing. And of
course one of us has the answer to that.
Or not, as the case may be.
