Droughts, heat waves, wildfires in some regions, water supply concerns, flooding rainfall in others

NOAA’s Climate Prediction Center
has issued an El Niño Watch, with El Niño now likely to emerge soon, an
82% chance during the May-July 2026 window, and continue through
Northern Hemisphere winter 2026-27, with a 96% probability through
December through February. A 96% probability of an event persisting
through winter is, as meteorologists put it, a near lock.
NOAA’s
previous April advisory had placed a 61% probability on El Niño forming
between May and July, with a 1-in-4 chance of a very strong event. Both
figures have since been revised upward based on a growing pool of warm
water building in the depths of the central and eastern equatorial
Pacific, which forecasters expect to rise to the surface and fuel El
Niño’s development. The pace at which these estimates are climbing is
itself significant. In most developing El Niño events, the models
converge slowly and cautiously. What is happening now is the opposite.
Michelle L’Heureux, a physical scientist at NOAA’s Climate Prediction Center, put it plainly in an ABC News report:
“There is a 2-in-3 chance of a ‘strong’ or ‘very strong’ El Niño during
the November 2026 to January 2027 season,” while acknowledging there
remains a 1-in-3 chance of an event weaker than that. Scientists are
being careful not to overstate what remains genuinely uncertain. But a
2-in-3 probability of a strong or very strong event is not uncertainty
that resolves quietly. NOAA also noted that stronger El Niño events can
only make certain impacts more likely; they do not guarantee strong
impacts in every region. That caveat matters, and it is worth holding.
Predictions based on a handful of historical super El Niños carry real
statistical limits.
Why This One Is Different From Every Previous Event
The
effects of El Niño will “be amplified considerably by the now nearly
1.5°C of global warming experienced as of 2026,” according to Daniel Swain,
a climate scientist at the University of California, Los Angeles. “In
modern human history,” he said, “we’ve never experienced a strong or
very strong El Niño event amid pre-existing conditions that were this
warm globally.”
That
framing is important. Every previous super El Niño unfolded against a
cooler baseline. The 1997-98 event, which remains the most destructive
El Niño in modern memory by most measures, occurred in a world roughly
0.5 degrees Celsius cooler than the one we are in now. A previous El
Niño helped drive average global temperatures in 2024 to a record 1.55
degrees Celsius above preindustrial levels. The world that produced that
record is the world today’s El Niño is building on top of.
A
more likely near-term impact is global heat: El Niño is loading the
dice toward 2026 or 2027 becoming Earth’s warmest year on record. NOAA
has already called it “very likely” that 2026 will be one of the five
warmest on record, and that assessment does not yet account for El
Niño’s warming contribution.
The climate system is being asked to absorb
two warming forces at once: the long-term human-caused trend and the
short-term ocean heat dump that El Niño delivers. During an extreme El
Niño event, an additional 0.2°C can be added to the average global
temperature on top of already elevated readings from warming, which
means global average temperatures could potentially exceed 1.7°C above
pre-industrial levels this year.
Fire, Flood, and the Regions Most at Risk
Droughts
and heat waves can flourish in some regions under El Niño, fueling
wildfire danger and water supply concerns, while others are swamped by
flooding rainfall. The geography of who gets what is not random; certain
regions have consistent El Niño signatures that repeat across events.
But the intensity and duration of those effects is harder to predict,
and this year’s elevated baseline makes the historical playbook less
reliable than it used to be.
The
wildfire picture is one of the more alarming dimensions of what is
coming. A super El Niño “against the backdrop of elevated baseline
temperatures could increase the risk of widespread or unusually intense
fires in normally damp regions where such fires are not common,” Swain
has warned, pointing specifically to the Amazon and parts of Oceania,
where peatlands “can burn for months on end.” Peatland fires are not
like forest fires. They smolder underground and release enormous
quantities of carbon into the atmosphere long after surface flames are
extinguished.
The
United States is already in a precarious position heading into this
event. Drought in the continental United States has expanded to its
record-highest level for spring, with varying levels of drought covering
62.78% of the country as of late April, the worst of it centered on
much of the South, West, and Plains. Dryness in the Lower 48 states has
not been this expansive in spring in the entire history of the U.S.
Drought Monitor, which holds data back to 2000. El Niño arriving into
already parched conditions is not the same as El Niño arriving into
normal spring moisture. The soil has no reserve. The vegetation is
already dry.
Globally,
the numbers are stark even before El Niño’s peak arrives.
Record-breaking heat and drought have fueled the world’s worst ever
start to a wildfire year, with more than 150 million hectares burned in
just the first four months of 2026, according to satellite estimates
from the Global Wildfire Information System,
a joint initiative of the GEO and Copernicus programs. That is an area
nearly the size of Alaska and roughly double the seasonal average for
this period.
When the Event Fades, the Damage May Not
The
dimension of the developing El Niño that climate scientists find most
disturbing is not necessarily what happens during the event. It is what
happens after.
A December 2025 study published in Nature Communications
found that abrupt and persistent transitions between stable states in
the climate system, what researchers call climate regime transitions,
pose serious threats to ecosystems and human well-being, and that the
likelihood of these transitions increases substantially during super El
Niño events due to their remarkable climate perturbations.
In plain
terms: the climate in some regions does not simply snap back to where it
was before the event. It arrives somewhere new, and it stays there.
In all three super El Niños on record alongside climate model projections,
the researchers found that events of this intensity increase the
likelihood of these abrupt, lasting changes in temperature, sea surface
conditions, and soil moisture that can endure for years or even decades.
The researchers also concluded that this destabilizing effect on
climate states will be greatly amplified under future greenhouse
warming, with the central North Pacific, the Gulf of Mexico, East
Africa, the Amazon, central Australia, and the Maritime Continent around
Indonesia likely to be worst affected.
The
implication is that the effects of a 2026 super El Niño may not simply
reverse when Pacific temperatures cool again; some changes could lock
in. One specific historical example: after the 2015-16 super El Niño,
the Gulf of Mexico reached a new sustained level of warmth that may have
contributed to stronger hurricanes along the Gulf Coast in the
following years. That is what a lasting climate transition looks like in
practice: not a dramatic collapse, but a floor that quietly rises and
does not come back down.
The Honest Limits of What Anyone Can Know Right Now
There
is a version of El Niño coverage that converts probability into
certainty, and it is worth resisting. With only three super El Niños on
record, the foundations of predictions about what this one will do are
shaky at best. “Scientists who are basing their conclusions on what is
likely to happen this time, based on a small sample of past events,
should not have as much confidence,” warned Paul Roundy, professor of
atmospheric science at the University at Albany, noting the uncertainty
about whether we are heading for supercharged global warming for the
next decade or an enhanced period of just a year or so.
The
World Meteorological Organization echoed that caution in its latest
Global Seasonal Climate Outlook, saying “a key source of uncertainty is
related to the potential intensity and duration of the El Niño event,”
and acknowledging that “while some model forecasts indicate the
possibility of stronger conditions later in the year, there is currently
no consensus or sufficient confidence to confirm or exclude a
high-intensity event.” The forecasting community is not hiding
uncertainty here. They are flagging it clearly. What they are not doing
is pretending the signal is not real.
While
forecasters are more confident in El Niño forming, “there is still
substantial uncertainty in the peak strength of El Niño,” the Climate
Prediction Center has stated. The odds of a Super El Niño between
November and January have increased from a 1-in-4 chance last month to
about a 1-in-3 chance in the latest strength probabilities. Those
numbers will continue to change. The models will be updated as the
ocean-atmosphere coupling either syncs up or fails to through the summer
months.
What This Means for You
The
question of how to hold a statistic like “82% probability of El Niño by
July” in a normal, practical life is a real one. It does not translate
into a specific action on a specific Thursday. It does translate into
paying more attention than usual to a few things.
Food
prices are one of them. El Niño’s disruption of rainfall and heat
patterns in agricultural regions has a documented track record of
pushing up commodity prices, grain, coffee, cocoa, palm oil, sometimes
sharply and sometimes with a several-month lag. Research shows that El
Niño events have been linked to crop failures, increased wildfire risk,
increased flood risk, heightened concurrent drought frequency,
disruptions to fisheries, and higher disease risk in various regions of
the world. Those links run eventually through grocery shelves.
Fire
season preparedness is another. If you live in the western United
States, the Southern Plains, the Southeast, or anywhere that was already
dry heading into spring, the combination of record drought and an
intensifying El Niño makes the period from now through late summer worth
paying attention to. Climate scientist Swain has stated plainly that
“it would not be surprising to see some unprecedented global impacts by
later in 2026 into 2027 in terms of flood, drought, and wildfire-related
extremes,” and that “either 2026 or 2027, or both, stand a good chance
of setting a new global temperature record, yet again.”
And
then there is the longer arc. The regime-transition research suggests
that even when El Niño itself is over, the world it leaves behind may be
measurably different from the one it found. Some of those changes will
be incremental and hard to notice. Some will not be.
What We’re Actually Watching
The
fact that scientists are being careful with their language right now is
not a sign that things might be fine. Careful language is what science
looks like when the evidence is strong enough to take seriously but the
sample size is small enough to stay honest. Both things are true here.
As
Wilfran Moufouma Okia, Chief of Climate Prediction at the World
Meteorological Organization, put it: “After a period of neutral
conditions at the start of the year, climate models are now strongly
aligned, and there is high confidence in the onset of El Niño, followed
by further intensification in the months that follow.” That is a
measured sentence from a careful organization, and it does not contain
any ambiguity about direction.
What
makes this moment genuinely new is not the El Niño itself. Natural
climate cycles have been running their course for as long as the ocean
has had weather. What is new is the world it is arriving into: one where
the atmosphere is warmer, the soil in large parts of the country is
already at record dryness, the wildfire season has already had its worst
start on record, and the buffer between “bad year” and “unprecedented
year” has been eaten away by a decade and a half of rising baselines.
The machinery is the same. The conditions it is operating in are not.
The Signal Is Real
You
do not need to follow the Niño 3.4 monitoring region on a daily basis
to feel what is coming. But it is worth knowing that this is not a
weather story. It is a compounding story: an already-hot planet, record
drought in the ground, a wildfire season off to its worst start in
history, and now a major Pacific warming event arriving faster than
forecasters expected just two months ago.
The
scientists most closely watching this are being honest about what they
do not know, and that honesty is worth taking seriously. They are not
certain this will be a record-breaking super El Niño. They are not
certain which regions will bear the worst of it or for how long.
What
they are saying, clearly and in measurable terms, is that the direction
of this is not in question, only the magnitude. And magnitude, in this
case, is the difference between a bad year and one that leaves a
permanent mark on the systems we all depend on, from food supplies to
coastlines to the dry hillsides behind towns that have never burned
before.
You
do not need to do anything differently on the strength of a weather
forecast. But if the summer turns unusually hot, the fires start earlier
and burn further, or the winter brings flooding in places that do not
expect it, you will know some of the reason why.
The ocean has been
trying to tell us something. The models are finally saying it out loud.
