Lagos Government Explains Cause of Citywide Flash Floods
The Lagos State Government has clarified that the flash flooding affecting parts of the city on May 20, 2025, is the result of increased tidal activity from the Atlantic Ocean and the Lagos Lagoon.
What Is Tidal Lockup?
According to Commissioner for the Environment and Water Resources, Tokunbo Wahab, the flooding is due to a phenomenon called tidal lockup. This occurs when rising sea tides especially during high rainfall prevent the natural discharge of stormwater into the ocean, causing a temporary backflow into the city’s drainage systems.
“Tidal lockup is not unusual during the rainy season in Lagos,” Wahab said. “Once the ocean and lagoon tides recede, the floodwater will naturally drain off.”
Areas Affected and Public Safety Alert
Several parts of the city, including Lekki, Victoria Island, Ikoyi, and parts of the Mainland, have experienced varying degrees of flooding. Inundated roads have slowed traffic and affected morning commutes, with residents sharing videos of submerged cars and waterlogged streets on social media.
Government Advice to Residents
The government has issued the following safety guidelines:
Avoid flood-prone areas during peak rain and tidal hours.
Stay updated via official Lagos State emergency channels.
Report blocked drains and emergencies to the Lagos State Emergency Management Agency (LASEMA).
Lagos Flooding and Climate Resilience Challenges
Lagos, a coastal megacity with a dense population and low-lying geography, faces increasing climate challenges. Seasonal flooding exacerbated by rising sea levels and rapid urban development puts additional pressure on the city’s drainage infrastructure.
The government insists that its drainage maintenance and early warning systems are operational and will help minimize the long-term impact of today’s flooding.
Thewatch.ng’s Take
Today’s flash floods highlight the delicate balance between urban expansion and environmental sustainability in Lagos. With climate change intensifying weather patterns, thewatch.ng news urges increased investment in eco-friendly urban planning, drainage upgrades, and citizen education.
