The Lagos State Government has issued an early warning that the state will experience above-normal rainfall amounts in the first peak of the 2025 rainy season, with a delayed cessation extending into December.
Speaking at the Seasonal Climate Prediction (SCP) press briefing in Alausa, the state Commissioner for Environment and Water Resources, Mr. Tokunbo Wahab, disclosed that the forecast indicates a “longer-than-usual rainy season, beginning in late March and ending in early December.”
This, he revealed in a post on X on Sunday.
“The rainy season is expected to start as early as the last week of March, while the end of the season is expected in the first week of December.
“The average annual rainfall amount predicted is 1,936mm, which is greater than the long-term 1991–2020 average,” Wahab said.
According to him, the forecast is based on the neutral phase of the El Niño Southern Oscillation (ENSO), which will persist for the first six to eight months of the year.
He explained that “Lagos State, alongside neighbouring Ogun State, will see an increase in rainfall, with Ikeja, Badagry, Ikorodu, Lagos Island, and Epe all experiencing above-normal precipitation levels.
“For instance, Ikeja is expected to have an onset date of April 2 and a cessation date of December 2, with an annual rainfall amount of 1,900mm. Badagry will see its first rains on March 30 and end on December 4, with 1,978mm of rainfall,” he stated.
Risk of Flash Floods, Strong Winds
The commissioner warned of possible flash floods, especially in low-lying areas, and strong winds at the beginning and end of the rainy season, which could pose risks to lives, properties, and economic activities.
“We anticipate that the high amounts of rainfall may lead to flash flooding events in some parts of the state..
“Strong winds are expected during the onset and end of the season, which could disrupt commercial activities, cause flight delays, and lead to revenue losses,” he cautioned.
Government’s Preparedness, Vigilance Call
Wahab assured residents that the state government is stepping up flood control measures to mitigate the impact of the predicted rainfall.
He emphasized that collaboration with NiMet remains a key strategy for early warning and climate adaptation efforts.
“The ministry is collaborating with NiMet in the annual Seasonal Climate Prediction, which has been a vital tool for farmers, planners, decision-makers, and businesses that could be affected by the rainy season,” he said.
Lagosians have been urged to stay alert, follow official weather updates, and take necessary precautions to safeguard their lives and properties as the Greater Lagos prepares for an intense rainy season, he concluded.
