Nigerians don’t need a meteorologist to tell them it’s hot. But another layer of climate pressure is on the way. At the start of the year, Nigeria’s official outlook looked fairly calm.
The Nigerian Meteorological Agency (NiMet) built its 2026 Seasonal Climate Prediction around a projected weak La Niña and a neutral phase of the El Niño Southern Oscillation. That outlook has since been overtaken.
NiMet’s August update says ocean observations confirm the onset of a strong El Niño event in 2026, and that it continues to intensify.
What is El Niño?
El Niño is a periodic warming of surface waters in the central and eastern tropical Pacific. It sounds remote from Lagos, Kano or Port Harcourt, but it shifts atmospheric circulation across the planet and changes where rain falls and where heat builds up.
The effects are not the same everywhere, and no two events behave identically. That uncertainty matters for Nigeria.
How strong is this one?
Forecasters expect a big event. FEWS NET, citing NOAA’s June outlook, described El Niño conditions as rapidly strengthening, with an 84% chance of strong or very strong conditions by September to November 2026. An African Union concept note for an emergency technical meeting says forecasting centres project a strong to very strong event in late 2026, peaking between November and January.
For Nigeria, that means the impacts may not be confined to this rainy season. They could run well into the dry season and the 2027 farming calendar.
Why Nigeria is hard to predict
West Africa’s monsoon is more complicated than a simple “El Niño equals drought” rule. Historically, El Niño has been associated with a higher chance of below-normal rainfall in parts of the region during the main rainy season.
But FEWS NET has flagged divergence between forecast models in how El Niño influences the West African summer monsoon, with significant implications for agriculture, water and food security.
The 2023/24 El Niño showed how mixed the picture can be. The AU note says it brought a mix of rainfall disruptions, floods and food-security stress across West and Central Africa, and notes that Nigeria saw flood-affected communities.
The honest answer is that Nigeria could face drought-like stress, flooding, or both in different places and at different times. Planning has to cover both.
The likely impacts
1. Agriculture and food prices.
Nigerian farming is overwhelmingly rain-fed. Late onset, dry spells in the middle of the season, or early cessation can cut yields of maize, sorghum, millet, rice and groundnuts. Erratic rainfall also disrupts planting dates. With food inflation already a burden on households, even modest harvest shortfalls can push up prices and deepen hunger, especially in the north, where many households are already vulnerable.
2. Flooding.
Intense downpours can still occur within an overall pattern of uneven rainfall. Nigeria’s low-lying coastal and riverine communities, and cities with poor drainage, remain exposed. Flooding destroys farmland and homes, displaces families, and contaminates water supplies.
3. Heat.
El Niño years tend to push global temperatures higher. For Nigeria that means more heat stress on people, livestock and crops, plus greater strain on an already fragile power grid when demand for cooling spikes.
4. Health.
Floods can bring cholera and other waterborne diseases. Heat and stagnant water can change the patterns of malaria and other vector-borne illness. Food insecurity worsens malnutrition, particularly among children.
5. Energy and the economy.
Hydropower from Kainji, Jebba and Shiroro depends on river flows. Drought-like conditions upstream can reduce generation, while floods can disrupt transport and supply chains. Agriculture is a major employer, so shocks to farming spread quickly through rural incomes and the wider economy.
You can’t control El Niño, but you can control how ready you are.
At home
Stock up wisely. If you can afford it, buy a few weeks of staples like rice, beans, garri, and cooking oil early, before shortages push prices up. Buy what you will actually use. Panic hoarding hurts your neighbours and your budget.
Store water safely. Keep clean, covered containers, and treat or boil drinking water if your source is doubtful, especially after heavy rain.
Prepare for heat. Drink water regularly, wear light clothing, and avoid strenuous work in the afternoon sun. Keep rooms ventilated, and check on babies, elderly neighbours and anyone with a chronic illness, since they are most at risk.
Plan for light and power. A solar lamp and a charged power bank go a long way when the grid fails, which tends to happen more in extreme heat.
If you live in a flood-prone area
Know your risk. Find out whether your street or community has flooded before, and where the nearest higher ground or shelter is.
Keep drains clear. Don’t dump refuse in gutters, and join neighbours to clear channels before the heavy rains.
Pack a grab bag. Keep copies of important documents in a waterproof bag, along with essential medicines, a torch and some cash.
Move valuables up. Raise electronics and important items off the floor during peak rainy periods.
A strong El Niño is developing, and Nigeria’s exposure is real, but its exact effect here is uncertain.
That uncertainty is a reason to prepare broadly rather than to wait. The countries and communities that fare best in El Niño years are those that act on early warnings.
