Nigeria may document 31,400 further deaths from excessive warmth over the subsequent six months as an intensifying El Niño climate sample threatens to worsen temperatures throughout the nation and the broader Sahel area, in accordance with a brand new report by the Climate Impact Lab.
The projections got here because the World Meteorological Organisation (WMO) and the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) warn that the present El Niño occasion may very well be unprecedented in power, elevating the dangers of utmost warmth, droughts and flooding throughout weak communities.
Speaking at a joint press convention on Wednesday, Celeste Saulo, WMO secretary-general, stated the phenomenon may peak in direction of the top of 2026, with its results persevering with lengthy after.
Here are 10 essential issues to find out about El Niño and what it may imply for Nigerians.
1. El Niño is a pure local weather phenomenon
El Niño is a part of a local weather sample often known as the El Niño–Southern Oscillation (ENSO). It develops when sea-surface temperatures within the central and jap equatorial Pacific Ocean change into hotter than regular, alongside modifications in atmospheric circulation.
These modifications can affect temperature, wind and rainfall patterns far past the Pacific Ocean.
El Niño is just not a storm, a heatwave or a illness. It is a large-scale local weather sample that may change the chance of specific climate situations in several components of the world.
2. “Super El Niño” is just not the official scientific time period
The phrase “Super El Niño” has gained consideration in information experiences and on social media amid discussions of the present occasion.
However, WMO describes the growing occasion as a “very strong El Niño.” Scientists assess its power utilizing measurements of Pacific Ocean temperatures and associated atmospheric situations.
The US National Oceanic and Atmospheric Administration (NOAA) additionally makes use of measurements and probability-based outlooks to watch the phenomenon. The terminology and exact thresholds can fluctuate with the index and company used.
3. It occurs naturally each few years
El Niño is just not a one-off occasion. According to NOAA, it happens on common each two to seven years and usually lasts between 9 and 12 months.
Its reverse section is named La Niña, when sea-surface temperatures within the central and jap tropical Pacific change into cooler than regular. Between the 2 phases, situations can return to ENSO-neutral.
Although the cycle is pure, its results may be particularly damaging after they coincide with weak communities, uncovered livelihoods or already elevated world temperatures.
4. The present occasion may persist into 2027
In its September 3, 2026, replace, WMO stated there was a near-100% chance that El Niño would persist via February 2027. Its forecasts indicated that the occasion may attain very sturdy depth earlier than peaking in direction of the top of 2026.
This is a forecast, not a assure of the precise timing or severity of climate occasions in particular person nations.
The sensible concern is that local weather impacts can proceed even after the Pacific Ocean occasion begins to weaken.
5. El Niño can enhance the danger of utmost warmth
El Niño can shift world temperature patterns and enhance the chance of unusually heat situations in lots of areas.
WMO’s September outlook indicated an elevated chance of above-normal temperatures throughout nearly all land areas for September to November 2026.
For folks, extended warmth can imply higher discomfort and elevated well being dangers, significantly for out of doors staff, older folks, younger youngsters and people with out dependable entry to cooling or water.
However, a worldwide temperature outlook shouldn’t be mistaken for a forecast of a selected heatwave in each Nigerian state.
6. It can disrupt rainfall, however not in the identical means in all places
One of a very powerful issues to grasp about El Niño is that it doesn’t make each place drier.
Some areas might expertise drought and extended dry spells, whereas others might face heavier rainfall, flooding or landslides. The outcomes depend upon the placement, season and interplay with different local weather programs.
In West Africa and the Sahel, historic El Niño patterns have been related to below-average rainfall throughout components of the July–September agricultural season. But this historic relationship can’t, by itself, set up precisely what is going to occur in Nigeria through the present occasion.
7. Nigerian farmers may face tough planting choices
Agriculture is among the sectors most uncovered to rainfall variability.
NiMet’s 2026 Seasonal Climate Prediction, launched on February 10, warned of variable rainfall, extended dry spells and usually hotter temperatures. It additionally recognized variations within the anticipated onset, cessation, and seasonal length of rainfall throughout Nigerian states.
These forecasts have been issued earlier than the present El Niño’s growth was absolutely mirrored within the later outlook. They ought to subsequently be learn alongside subsequent updates.
If rainfall turns into poorly timed, farmers might face crop stress, disrupted planting schedules and decrease yields. Livestock keepers may additionally face stress on pasture and water provides.
8. Food costs may come beneath stress, however will increase aren’t inevitable
When climate disrupts agricultural manufacturing, the implications can lengthen past the farm.
Lower harvests or difficulties transporting produce can put stress on meals provides. If a number of producing areas are affected, households might face further monetary pressure.
The UN Food and Agriculture Organisation warns that El Niño can threaten meals manufacturing, rural livelihoods, and meals safety, significantly in communities with restricted assets to soak up losses.
For Nigeria, nevertheless, any declare that El Niño will robotically trigger meals costs to rise can be untimely. Prices additionally depend upon transport prices, insecurity, imports, trade charges, storage, authorities insurance policies and different components.
9. Flooding stays a priority for Nigeria
A rustic can expertise dry spells and nonetheless undergo flooding. Heavy rain concentrated into a brief interval can overwhelm drainage programs, trigger flash floods and lift river ranges.
Nigeria’s flood dangers should subsequently be assessed utilizing native hydrological data, not El Niño forecasts alone.
The Nigeria Hydrological Services Agency (NIHSA) gives a 2026 Annual Flood Outlook and an interactive dashboard exhibiting flood publicity throughout states and the Federal Capital Territory. Its outlook may also help residents test their very own areas.
Residents ought to monitor official warnings, keep away from driving or strolling via floodwater, and observe evacuation directions from emergency authorities.
10. Early warnings can save lives and livelihoods
El Niño can’t be stopped, however its potential impacts may be lowered via well timed preparation.
NiMet gives seasonal local weather predictions, rainfall data and agricultural advisories. NIHSA publishes flood and drought outlooks, whereas the National Emergency Management Agency (NEMA) coordinates catastrophe preparedness and response.
Farmers can use official forecasts to plan planting and put together for dry spells. Communities can determine evacuation routes and shield important paperwork earlier than flooding happens. Government companies may use early warnings to arrange water provides, emergency providers and humanitarian help.
WMO stresses the significance of turning local weather forecasts into early motion, significantly when an occasion is anticipated to change into unusually sturdy.
The key message is that preparation ought to start earlier than the impacts change into seen.
