The Nigerian Meteorological Agency (NiMet) has revealed that there would be earlier than the long-term average rainfall in most parts of the country.
To this end, the agency stated that parts of Katsina, Zamfara, Kano, Jigawa, Yobe, Cross River, Ebonyi, Imo, and Rivers would likely experience delayed onset of rainfall.
At the launch of the 2023 Seasonal Climate Prediction (SCP) in Abuja on Tuesday, Minister of Aviation, Sen. Hadi Sirika hinted that the onset dates for rainfall ranges from 2nd March to 7th July 2023.
“The onset is expected to become established in early March from the coastal states of Bayelsa, Rivers, and Akwa Ibom; in April for the Inland States of the South; in May around the central States and around July in the northern States", he said.
Sirika noted that parts of Yobe, Jigawa, Kano, Bauchi, Kaduna, and FCT would likely observe below normal to near normal annual rainfall.
He said that the annual rainfall amount is expected to range from 420 mm in the far northernmost parts to 3253 mm in the coastal areas.
The minister pointed out that strong windstorms across the country and sandstorms in the extreme northern states could occur before the onset of rainfall.
On dry spells, he added: “Dry spell occurrences have characterised our seasons in recent years. In 2023, we should also prepare for its occurrence between June and early July as dry spell lasting between 15 to 21 days is in the forecast, especially from the central parts of the country to the North.
“When compared to the last years, the little dry season (August Break) for 2023 is expected to be less intense. It is expected to last between 14 and 20 days starting from late July, especially over the Southwest of the country.”
He said that the rains are expected to end from the 26th of September to 25th of December.
“An early End of Season (EoS) is predicted over parts Osun, Ondo, Edo, Delta, Imo, Bayelsa, Rivers, Akwa Ibom, Ogun, Lagos, Yobe, Adamawa, Niger, Nasarawa and Kogi.
“However, an extended rainfall season is predicted over parts of Gombe, Kaduna, Kwara, Enugu, Anambra, western Ogun, and Lagos", he concluded.
