Lagos flash flooding due to increased tidal levels from Atlantic Ocean, Lagoon – Environment commissioner

The Lagos State Commissioner for the Environment and Water Resources, Tokunbo Wahab, says the flooding currently being experienced in some parts of the state is as result of the increased tidal level from both the Atlantic Ocean and the Lagos Lagoon.

His post reads:

Dear Lagosians,

The Lagos State Government wishes to inform the public that the flash flooding currently being experienced in parts of the city is due to increased tidal levels from both the Atlantic Ocean and the Lagos Lagoon.

This natural phenomenon, known as “lock up”, occurs when high tide temporarily prevents rainwater from discharging into the sea. As a result, storm water backs up, leading to flash floods in low-lying areas. We assure you that once the tide recedes, within 1–2 hours after the rain stops, the floodwater will naturally drain off.

We appeal to all residents to remain calm and avoid panic. Our emergency response and drainage maintenance teams are actively monitoring the situation.

Please DO NOT dispose of waste into drains and gutters. Such actions block water flow and worsen flooding. Proper waste disposal is a civic responsibility we must all uphold to ensure a flood-resilient Lagos.

Let’s continue to work together for a cleaner, safer, and more sustainable environment.
