Rains and intervals of sunshine will spread across Nigeria between Monday and Wednesday, the Nigerian Meteorological Agency has forecast, in a routine outlook that lands squarely within the window meteorologists have flagged as the most dangerous stretch of the 2026 wet season.
According to the weather outlook released in Abuja on Sunday, the northern region should expect largely sunny skies with patches of cloud through the three days, with isolated thunderstorms and light to moderate rains over parts of Taraba during the afternoon and evening. The North Central region will see a cloudy atmosphere with sunshine intervals throughout the period. In the south, the agency anticipates cloudy conditions broken by sunshine, with thunderstorms and light to moderate rains over parts of Rivers, Bayelsa, Akwa Ibom, Cross River, Delta, Edo, Ondo, Osun, Ogun, Lagos and several South East states, particularly later in the day on Tuesday and Wednesday.
The agency advised that strong winds may precede the rains where thunderstorms are likely, urging the public to fasten loose objects, avoid driving in heavy rain, disconnect electrical appliances and keep away from tall trees. Airline operators were advised to obtain airport specific weather reports for flight planning. NiMet also noted that temperatures would remain high enough to cause thermal discomfort, recommending breathable clothing and adequate hydration.
The forecast reads as ordinary, but its timing is not. Nigeria is now in the middle of the period that its own hydrological and meteorological agencies identified months ago as the peak of this year’s flood risk. The 2026 Annual Flood Outlook, published by the Nigeria Hydrological Services Agency in April, identified 14,118 communities across 266 local government areas in 33 states and the Federal Capital Territory as high risk flood zones, with the greatest danger expected between July and September. NiMet’s 2026 Seasonal Climate Prediction, released earlier in the year, had similarly warned of above normal rainfall, prolonged rainy seasons, delayed cessation of rains in parts of the south and a heightened likelihood of flash floods.
Those warnings have already translated into loss this year and last. Only days before this outlook, on 9 September, NiMet issued a separate alert warning of possible flash floods in Imo, Abia, Ebonyi, Akwa Ibom and Cross River. The current forecast again lists several of the same southern states among those expecting thunderstorms and rain, a pattern consistent with the delayed cessation the agency had projected for the region.
The human cost of underestimating such forecasts is well documented. On 28 May 2025, floodwaters submerged the market town of Mokwa in Niger State in what became the deadliest single flood event in the country in at least two decades. Figures released by the National Emergency Management Agency and the Niger State Emergency Management Agency at the time put confirmed deaths above 150, with more than 3,000 people displaced and over 500 households affected. Later tallies, including international reporting and community level records, placed the death toll higher, at more than 500, with hundreds recorded as missing and thousands of homes destroyed. The disaster followed the same seasonal warnings that precede this week’s outlook.
The longer record shows how routine these losses have become. Nigeria’s worst flooding in more than a decade occurred in 2022, when NEMA data recorded over 600 deaths, about 1.4 million people displaced and roughly 332,000 hectares of farmland lost across more than 30 states. The 2024 season was heavier still by most aggregated counts, with figures compiled from state emergency agencies and reported internationally putting deaths above 1,200 and the number of Nigerians affected at more than five million, though NEMA’s own verified count for that year was considerably lower. The gap between agency verified figures and aggregated community data is itself a recurring feature of Nigerian flood reporting, and it means casualty totals should be read with caution rather than treated as settled.
Government has moved, at least on paper, to prepare for 2026. In June, the National Economic Council approved N83.2 billion for proactive interventions against flooding and other climate related emergencies, a decision taken directly against the backdrop of the NiMet and NIHSA projections. State governments in flagged areas, including Niger and Kogi, have announced preparedness measures, and NEMA has published a climate related risk management framework for the year. Whether these measures reduce the toll will only be measurable at the end of the season, and past years have shown that early warning has repeatedly outpaced early action.
For most households, the practical value of a three day outlook lies in the ordinary precautions the agency lists. But the outlook also functions as a marker of where the country stands in a season whose risks were mapped long before the first rains. Agriculture, which employs a large share of the workforce, is particularly exposed, with the 2026 outlook estimating millions of hectares of cropland at risk, a concern that feeds directly into food supply at a time when food inflation stood at 20.31 per cent year on year in July, according to the National Bureau of Statistics.
NiMet advised residents to stay informed through updates on its website. The agency issues its outlooks daily, and the next few weeks, covering the tail of the identified high risk window, will test how far this year’s preparations hold. What the forecast confirms for now is modest but not trivial: the rains are continuing on schedule, in regions already warned, during the months the data long ago marked as the most hazardous.
