The Lagos government has issued an early warning that the state will witness above-normal rainfall in the first peak of 2025 with a delayed cessation extending into December.
Speaking at a press conference, Tokunbo Wahab, the state commissioner for environment and water resources, said the forecast indicates a “longer-than-usual rainy season, starting in late March and ending in early December”.
The commissioner said the rainy season is expected to start as early as the last week of March and end in the first week of December.
“The average annual rainfall amount predicted is 1,936 mm, which is greater than the long-term 1991–2020 average,” Wahab said.

He noted that 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.
“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,” he added.
“Ikeja is expected to have an onset date of April 2 and a cessation date of December 2, with an annual rainfall amount of 1,900 mm. Badagry will see its first rains on March 30 and end on December 4, with 1,978 mm of rainfall.”

The commissioner also warned of the possibility of flash floods in low-lying areas and strong winds at the beginning and end of the rainy season.
“We anticipate that the high amounts of rainfall may lead to flash flooding events in some parts of the state,” he warned.
“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.”
The commissioner also assured residents that the state government is stepping up flood control measures to mitigate the impact of the predicted rainfall while emphasising that collaboration with NiMet is a key strategy.

“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.
He urged Lagosians to stay alert, follow official weather reports, and take necessary precautions to protect their lives and properties as the state prepares for an intense rainy season.
