You’ve probably seen the headlines. A “super El Niño” is building in the Pacific; forecasters are using words like “historic,” and one report says tens of thousands of Nigerians could die from heat. Here’s what is solid, what is shaky, and what it means for us.
First, what is El Niño?
El Niño is a natural climate pattern that returns roughly every two to seven years, though not on a schedule. Normally, steady winds push warm water across the tropical Pacific. During El Niño, those winds weaken, and the warm water drifts east. That change reshuffles rain and heat patterns across the world, including in West Africa.
Why “super”?
It’s a nickname, not an official category. Neither NOAA, the US weather and climate agency, nor the World Meteorological Organisation uses it. Forecasters apply it informally when the central Pacific runs about 2°C above normal. NOAA now gives an 83% chance that this will be the strongest El Niño since records began in 1950. The WMO says it’s almost certain to last through February 2027, with a peak toward the end of this year.
El Niño itself is natural, and the WMO is explicit that climate change doesn’t cause it. The problem is the backdrop. This event is landing on a planet that is already warmer, which is why scientists worry about its extremes.
What does it mean for Nigeria’s rain?
Less than you might expect, and the picture is mixed. Regional forecasters stress that a strong El Niño doesn’t automatically mean a dry season across the whole Sahel and West Africa, because conditions in other oceans, like the tropical Atlantic, also matter. Their outlooks flagged possible rainfall deficits in the northwest, while other parts of the country are harder to call. NiMet confirmed in its August update that a strong El Niño is underway.
The bigger worry is food
The WFP and FAO project nearly 6 million more hungry people across West and Central Africa, a 12% rise in food insecurity. Because El Niño also affects future harvests, the effects could last through 2027, and they’re landing on top of already high fuel and fertilizer prices. Cocoa is exposed too: every strong El Niño in the past 55 years has reduced global cocoa production. Aid agencies have also flagged dengue fever, malaria and cholera as major concerns in several affected countries, though that report doesn’t single out Nigeria.
“But the news said we might die?”
This is the claim that has been spreading. The Climate Impact Lab at the University of Chicago projects about 31,400 additional heat-related deaths in Nigeria between September 2026 and February 2027, the highest of any country. For the wider Sahel it estimates 66,800, and for the world, 451,000.
Several caveats matter. It is a model, not a body count, and it counts extra deaths compared with the average for the same months from 1996 to 2025. The study has not been peer-reviewed yet, though its authors say it uses peer-reviewed methods and released it early because the window for action is short. An independent researcher at the University of Warwick called the global estimate plausible as a modelling exercise but not a definitive prediction. Nigeria’s high number also reflects its population of roughly 237 million, so it doesn’t mean Nigerians face the highest risk per person. The projection also covers heat only, not deaths from drought, floods or food shortages.
What actually helps
The researchers point to early heat warnings, health action plans, cooling and hydration centres, and wider healthcare coverage. At a personal level, the basics are simple: drink water, avoid the hottest part of the afternoon, check on elderly neighbours, and protect people who work outdoors.
The bottom line
This is a real, potentially record-breaking event, and heat and food are the two areas to watch. But “tens of thousands will die” is a projection that experts say should drive preparation, not panic. Forecasts will keep changing as the event develops, and we’ll keep you updated.
