The Lagos State Government has warned residents to prepare for possible flooding, strong winds, and above-normal rainfall as the 2026 rainy season approaches.
The Commissioner for Environment and Water Resources, Tokunbo Wahab, issued the advisory during a press briefing in Lagos, where he outlined the seasonal climate outlook and its potential impact on the state.
Wahab explained that the forecast is based on predictions released on February 10 by the Nigerian Meteorological Agency (NiMet), which analysed expected rainfall patterns, temperature changes, and other weather indicators across the country.
According to him, the ministry conducts the annual briefing to help residents and government agencies prepare for the environmental and socio-economic effects of the rainy season.
Early Onset, Longer Rainfall Expected
The commissioner said the 2026 outlook indicates that Lagos may experience an early onset of rainfall and a longer rainy season.
He attributed the projection to a predicted weak La Niña and a neutral phase of the El Niño–Southern Oscillation (ENSO), climate patterns known to influence rainfall and temperature levels.
The rainy season in Lagos is expected to begin around the last week of March and continue until early December.
NiMet projections indicate that rainfall could start around March 31 in Ikeja with about 1,932 mm of rainfall; March 28 in Badagry with approximately 2,010 mm; March 31 in Ikorodu with about 1,935 mm; March 30 on Lagos Island with around 1,968 mm; and March 29 in Epe with about 1,984 mm.
Overall, the average annual rainfall expected across the state’s 20 local government areas is estimated at about 1,965 mm.
Flood Risks and Strong Winds
Wahab warned that heavy rainfall could trigger flooding in vulnerable communities across the state.
He added that strong winds, particularly at the beginning and end of the rainy season, could damage property and pose risks to residents.
Thunderstorms and intense downpours may also disrupt commercial activities and lead to possible flight delays, he noted.
Government Preparedness Measures
The commissioner said the state has strengthened its monitoring systems through weather and river gauge stations to improve preparedness for flood-related incidents.
He added that the ministry is working closely with NiMet to provide early warning information to farmers, businesses, and urban planners.
Flood control efforts, including the continuous clearing and dredging of drainage channels and improved waste management, have also been intensified.
In addition, the state government is collaborating with the Ogun-Oshun River Basin Development Authority to regulate water releases from the Oyan Dam to reduce flooding risks along the Ogun River.
Communities such as Agiliti, Agboyi, Itowolo, and Ajegunle are currently under close monitoring due to their vulnerability to river flooding.
Advisory to Residents
Wahab urged residents to avoid dumping refuse in drainage channels and warned against constructing buildings on flood plains.
He also advised residents in flood-prone areas such as Owode, Iwaya, Makoko, Badia, Ijora, Isaalu, Pota, and Shibiri to remain alert and be ready to relocate to safer locations if necessary.
Motorists were also urged to observe speed limits during heavy rains, while households were encouraged to regularly clear drains around their homes to ensure the free flow of stormwater.
