As the world prepares for the possible effects of a strengthening El Niño climate event, Nigerians are being urged to take precautions against extreme heat, changing rainfall patterns and possible pressure on food and water supplies.

The National Emergency Management Agency (NEMA) issued a public advisory on October 26, 2026, encouraging individuals, families and communities to prepare for the potential effects of the developing climate phenomenon.

But what exactly is El Niño, and how could it affect Nigeria?

What Is El Niño?

El Niño is a natural climate phenomenon that occurs when surface waters in the central and eastern tropical Pacific Ocean become unusually warm.

This warming affects atmospheric circulation and can influence weather patterns across different parts of the world.

Its effects vary by location. Some regions may experience hotter conditions and drought, while others may experience unusually heavy rainfall and flooding.

According to the Nigerian Meteorological Agency (NiMet), its August 2026 climate update confirmed the onset of a strong El Niño event.

The US National Oceanic and Atmospheric Administration (NOAA) also reported on October 8 that the event was continuing to strengthen, with a strong-to-very-strong event likely through early 2027.

How Could El Niño Affect Nigeria?

Nigeria could experience changes in temperature and rainfall patterns as the climate phenomenon develops.

Potential concerns include:

• Higher temperatures and increased heat stress.
• Changes in rainfall patterns.
• Pressure on water supplies.
• Challenges for farmers and livestock owners.
• Possible effects on food production and household expenses.

However, the effects will not necessarily be the same across all Nigerian states.

10 Ways Nigerians Can Protect Themselves

As the country prepares for possible extreme weather conditions, here are practical steps Nigerians can take.

1. Drink enough clean water

Drink water regularly throughout the day, particularly when working outdoors. Avoid waiting until you feel thirsty before drinking.

2. Avoid prolonged exposure to direct sunlight

Where possible, reduce outdoor activities during the hottest part of the day, particularly between 11 a.m. and 4 p.m.

3. Wear lightweight clothing

Choose loose-fitting, breathable clothing. Hats, caps and umbrellas can also help protect against direct sunlight.

4. Protect children and elderly people

Children, older adults and people with existing health vulnerabilities may be more susceptible to heat-related illnesses. Check on them regularly.

5. Keep your home properly ventilated

Improve airflow by opening windows when outdoor conditions are cooler. Use fans where available and avoid unnecessary heat-generating activities indoors.

6. Avoid wasting water

Repair leaking taps and store water in clean, covered containers. Protect wells and other water sources from contamination.

7. Protect food supplies

Households should plan food purchases carefully, while farmers should consider drought-resistant crops and suitable farming practices.

8. Recognise the symptoms of heat-related illness

Dizziness, headaches, nausea and unusual weakness can be warning signs. Confusion, fainting or seizures require emergency medical attention.

9. Maintain good hygiene

Practise proper sanitation, wash hands regularly and keep surroundings clean to reduce the risk of waterborne diseases.

10. Follow official weather updates

Stay informed through NiMet, NEMA and other reliable authorities. Avoid spreading unverified weather warnings on social media.

What Should the Nigerian Government Do?

Individual precautions are important, but government preparedness is equally necessary.

Federal and state authorities should strengthen public awareness campaigns, improve access to clean drinking water and ensure that healthcare facilities are prepared for heat-related emergencies.

Farmers should also receive timely weather information and support to adapt to changing rainfall conditions.

Public spaces, schools, markets and workplaces should consider practical measures to protect people from prolonged heat exposure.

Conclusion

El Niño is a natural climate phenomenon, but its potential effects should not be ignored.

For Nigeria, early preparation, access to reliable weather information and public awareness can help reduce the risks to health, agriculture and livelihoods.

As temperatures and weather patterns continue to change, Nigerians must remain informed and take simple precautions to protect themselves, their families and their communities.

Stay informed. Stay prepared. Stay safe.
