The Flooding Season Is Not Over. Here Is What Nigerian Developers Should Be Doing Right Now.
NiMet has issued flash flood warnings for Lagos, Ogun, and 25 other states. Lagos Commissioner Tokunbo Wahab has warned residents in Eti-Osa, Lagos Island, Ajah, and Kirikiri to move to higher ground. Cross River displaced 347 people in a single week. Plateau State lost over 100 homes to a rainstorm. Ifako counted losses after streets were submerged in hours.
The flooding season is not over and the sector’s response to it cannot wait until the rains stop.
What Is Still Coming
Nigeria’s rainy season typically runs through October. NiHSA’s 2026 flood outlook flagged over 14,000 communities as high risk before the season began. The communities that have flooded already are not necessarily the only ones that will flood before the year ends. Developers with active sites, completed projects, and properties under management need to be acting now, not waiting for the next headline.
What Developers Should Be Doing
Active construction sites in flood-prone areas need immediate drainage assessment. Heavy rainfall on an exposed site without adequate water management can undermine foundations, damage materials, and delay project timelines in ways that cost significantly more to fix than to prevent.
Completed properties in flood-vulnerable corridors need their drainage systems checked and cleared before the next heavy rainfall event. Blocked drainage channels are the most common reason a development that was designed adequately floods anyway. Maintenance is not a luxury, it is the difference between a building that functions and one that fails its occupants.
Property managers need to communicate proactively with tenants in flood-exposed buildings. Residents who receive early warning, know where to move valuables, and understand evacuation routes are residents who can recover faster. The cost of that communication is negligible and the cost of not having it is borne by people who did not need to absorb it.

What Buyers Should Know Right Now
Anyone currently in the process of purchasing property in Lagos or any of the other 25 states under NiMet flood warning should pause and ask the questions that the warning makes urgent. Has this area flooded before? Where does stormwater go from this site? Is the drainage adequate for the rainfall volumes now being forecast?
These are not questions to ask after purchase, they are questions to ask before signing.
Conclusion
The flooding season is not over, the warnings are active, the data is available. What Nigerian developers, property managers, and buyers do with that information in the next few weeks will determine whether the end of this rainy season produces more headlines or fewer. The choice is not about whether it will rain, it is about whether the sector is ready when it does.
