The Federal Government has issued a warning that 33 states along with the Federal Capital Territory (FCT) are likely to face significant flooding in 2026, potentially impacting more than 14,000 communities nationwide.
The most intense flooding is expected between July and September, posing serious threats to agriculture, housing, and infrastructure.
Areas along the coast, riverbanks, and densely populated cities—such as Lagos, Abuja, and Ibadan—are particularly at risk due to heavy rainfall and inadequate drainage systems.
The report, developed by the Nigeria Hydrological Services Agency (NIHSA), uses data analysis to forecast flood patterns and help both authorities and citizens prepare ahead of the rainy season.
The theme for 2026, “Smart Water Resources Management – Moving from Oil to Water-Based Economy,” underscores the increasing importance of effective water management in Nigeria’s development.
The Minister emphasized that early warnings are essential for saving lives, safeguarding infrastructure, minimizing economic losses, and improving planning for farmers and communities.
Flooding is projected to occur between April and November 2026, with varying levels of risk throughout the year:
April–June: About 9,021 communities in 188 LGAs at risk
July–September: Around 14,158 communities in 263 LGAs (peak period)
October–November: Approximately 11,575 communities in 224 LGAs
This indicates that the mid-year rainy season will be the most critical period.
While not all regions will experience severe flooding, many remain vulnerable:
Moderate risk: 15,597 communities in 405 LGAs across 35 states (excluding Ekiti)
Low risk: 923 communities in 77 LGAs across 24 states
Even moderate flooding can still cause damage to crops, homes, and roads, especially in areas with poor drainage.
Urban flooding is also a major concern, particularly in cities prone to heavy rainfall and weak drainage infrastructure. Flash floods may occur suddenly in places like Abakaliki, Abeokuta, Abuja, Benin City, Ibadan, Lagos, Port Harcourt, and others.
Additionally, coastal and riverine states—such as Bayelsa, Delta, Lagos, Rivers, and Ondo—face heightened risks from rising water levels and tidal surges, which can disrupt fishing, damage ecosystems, and hinder water transportation.
Authorities are advising state governments to upgrade drainage systems, communities to clear blocked waterways, farmers to adjust planting schedules, and residents to stay informed through weather updates.
Taking preventive action early can significantly reduce the impact of flooding during the peak rainy season.
