This El Niño is off the charts.

In the middle of August, water in the Eastern Pacific is already at temperature anomalies only ever seen at the December peak of the strongest El Niño on record. I wanted to offer some perspective on just how crazy this is.

Meteorologists and adjacent weather nerds like me have been watching with alarm for months a rising El Niño that is racing past historic benchmarks on a path to likely becoming the strongest in recorded history. In recent weeks, media outlets have started adding sensational headlines about global impact and speculating on local impacts (like big snow seasons in the West).

While I’ve watched with dismay over the past decade as insider-ish weather terms like the “polar vortex” and “bombogenesis” have escaped containment to become social media clickbait headlines that generate more noise than real awareness, this El Niño, I’m afraid to say, will earn the attention it gets.

I think most people vaguely understand that El Niño = “bad weather” somewhere. But it’s not the kind of climate event that suits our modern short-attention, hype-cycle media diets. In fact it tends to suppress the East Coast hurricanes that fuel news cycles. This will last months, testing patience and resilience where its worst effects are felt. But as of now, this El Niño’s strength is less felt than measured by a set of indices that would cause most people to tune out quickly. So below, I took a crack at some comparisons from pop culture that might help to put this historic pace in perspective.

But first, why you should care.

What is El Niño?

In the 1600s, fishermen along the Peruvian and Ecuadorian coasts of South America noted a warming of the eastern Pacific waters that occurred around Christmas. They called the warm current El Niño de Navidad, Spanish for “the little boy” or “the Christ Child.” They were observing what scientists came to understand is a naturally occurring, periodic relaxation of the east to west winds across the tropical Pacific. Normally, the winds push warm surface water toward Asia, allowing cool water to rise to replace it near South America. When the winds weaken, the warm water slides back east, and the middle of the ocean heats up. That is what we know as El Niño.

Why does it matter?

The enormous patch of warm ocean water that develops during El Niño drives changes to weather patterns that frequently result in extreme floods and droughts. Rain that usually falls over Indonesia falls over the central Pacific instead. Storm tracks shift and California and the southern U.S. tend to get soaked with rain. Australia and Southeast Asia tend toward drought and fire and the whole planet runs a little hotter.

In the modern era, measurement of El Niño has been standardized on how far the sea surface temperature in a box called Niño 3.4 sits above or below its normal for the date. The strongest El Niños measured in the modern era have led to global disasters:

  • 1982–83 — about $8 billion in damage at a time when forecasters didn’t yet realize an event was underway. Torrential rain and floods wrecked villages and fisheries on Peru’s coast, while the flip side, deep drought in Australia, fed the Ash Wednesday bushfires that killed 75 people in a single day.

  • 1997–98 — roughly 23,000 deaths and $35 billion in damage worldwide. Peru and Ecuador flooded again; drought-fueled fires in Indonesia wrapped Southeast Asia in haze that closed airports and sickened millions; an estimated 16% of the world’s coral died in the first global bleaching event. 1998 became the hottest year on record to that point.

  • 2015–16 — the strongest yet measured. Drought pushed 60 million people into food insecurity, including Ethiopia’s worst drought in half a century, and a global bleaching event killed about 30% of the Great Barrier Reef’s shallow-water coral. Global temperature records fell and stood until 2023. Locally, in NYC, we had a record-obliterating warm December culminating in a 72-degree Christmas Eve (followed 4 weeks later by a historic blizzard).

Climate scientists have also come to understand that some disasters in the historic record are attributable to El Niño, including the deadliest climate event in recorded history — a monster El Niño in 1877–78 that drove simultaneous drought across India, China, and Brazil; the famines that followed killed an estimated 30 to 60 million people, 3–4% of everyone alive. In India alone, 6 to 10 million died as crops failed and colonial policy kept grain exports flowing. Northeastern Brazil lost roughly half a million people.

Why the current El Niño is so alarming.

You may have heard: we are already in a cycle of global warming that is outpacing forecasts and models. And warming seas are already contributing to stronger storms and more intense rainfall globally. So this El Niño — and those to come in future decades — is happening on top of a global environment that is already breaking from past predictions and difficult to model.

El Niños usually build slowly through summer and peak around Thanksgiving through New Year’s (recall “The Christ Child”). That is not what is happening this year. On August 13 the Niño 3.4 anomaly stood at +2.71 °C. The previous record for the date was +1.90, and only 58 of 16,418 days since 1981 have ever been warmer, all of them at the midwinter peak of the record 2015/16 event (+3.08).

Does this mean El Niño is just peaking early? Sadly, no. Forecast models still project a peak of the event in October–December. NOAA now puts the odds of a very strong El Niño above 90% and gives 69% odds of a historic one, stronger than anything measured since 1950. If 2026 proceeds at the same rate as 1997 and 2015 from mid-August to their peaks, it would land between +3.5 and +4.1.

But no event has ever been this strong this early, so there is no precedent that says this pace will hold, for better or worse.

You can probably read that chart and see how far ahead we are right now. But I don’t think most people have useful frames of reference for a +2.7 °C sea surface temperature anomaly in August. While a +3.3 standard deviation anomaly for the date might wake up the true stat heads, I’ve been asking myself, how else could we put this in perspective?

It’s like Black Friday arriving in August.

El Niño events peak in late fall like holiday shopping does.

The only days that ever matched the most recent August reading came between November 2015 and January 2016, at the height of the strongest recorded El Niño.

So imagine holiday shopping around the country fully taking hold by early August, out-ringing every Black Friday in history but one.

Black Friday 2026 falls on November 27. The Pacific rang up numbers bigger than every past holiday season but one — on a Tuesday in early August.

Imagine a week of 76° days in Boston. In the first week of March.

Nice, but alarming. Calibrated against 90 years of daily records at Logan Airport, a +3.3 sigma day in early March works out to about 76°F, warmer than any first week of March Boston has ever had.

Calibrated on Boston Logan daily highs, 1936–2025: a +3.3σ day in early March ≈ 76°F. In 90 winters, no day before March 8 has ever reached 76°. Days that far outside normal for their date, in any season, come along about once every three to four years.

Let’s put this El Niño in perspective against some individual records.

Comparing where the current El Niño is to some of the greatest individual performances in sports and film just might give a better frame of reference for how wild it is.

It’s like…

Each panel: the top two record holders' real cumulative trajectories (blue and gray), a marker at the equivalent point on the season or career clock (~55% of the way to the peak), and the orange dot at the El Niño-equivalent value — 88% of the all-time record, which is where the Pacific sits today.

What happens from here?

This El Niño’s peak still lies ahead. Dynamical models point to a peak in record territory — their average tops +3, with several members above +4, while some statistical models are betting it can’t sustain a pace like this. Even at the low end of the forecasts, it will be one of the strongest ever, leading to a winter of localized extreme weather, but also a broad global temperature spike that will continue to accelerate the of melting glaciers and thawing of permafrost.

Sources & methods

Historical impacts: 1877–78 famine mortality ranges from Singh et al., Journal of Climate (2018) and associated scholarship on the Great Drought; 1997–98 deaths and damage per NOAA NCEI; 1982–83 damage and 2015–16 food-security figures per NOAA and UN reporting. Estimates of this kind carry wide uncertainty, and famine deaths reflect policy failures as much as weather.
