Heavy rainfall in front when Nimet predicts up to 290 days of rain in southern Nigeria for 2025

The nigerian southern coastal countries are in a long and wet year, according to the 2025 seasonal climate predictions issued by the Nigerian Meteorology Agency (NIMET) on Monday.

The report predicted which stated such as Lagos, Delta, Bayelsa, Cross River, Rivers, and Akwa Ibom will experience between 250 and 290 days of rain, the highest throughout the country.

This estimate marks the continuation of the climate pattern driven by global and regional weather changes, and it comes with implications for agriculture, infrastructure, and flood preparedness in vulnerable communities.

Professor Charles Anosike, Director General of Nimet, through an official release, said the southern coast countries will not only record the highest number of rainy days but also the toughest total rainfall, ranging from 2,700 mm to 3,010 mm for this year.

Further to the north, however, striking contrast appears.

In the northeast and northwest states of Nigeria, including Borno, Yobe, Sokoto, and Katsina, rainfall will be limited, with an annual total will fall below 685 mm, and rainy days projected between 110 and 150.

Countries in the central belt such as Niger, Kogi, Benue, Plateau, Nasarawa, Kwara, and FCT are expected to record 150 to 200 days of rain, with rainfall ranging from 970 mm and 1,500 mm.

Meanwhile, Ogun, Oyo, Ekiti, Osun, Ebonyi, Anambra, and Enugu will see between 200 and 250 days of rain.

This report also indicates the pattern of rainfall which is mostly normal to normal in Nigeria, compared to long-term averages. However, certain areas, including Kaduna, Ebonyi, Cross River, Lagos, Abia, Akwa Ibom, and FCT parts, are projected to receive rainfall above normal, increase concerns about the potential for flash floods and erosion.

Nimet estimates that the emergence of rainfall will vary greatly throughout the region:

  • Southern countries such as Lagos, Ogun, Ondo, Ekiti, Edo, Cross River, and Ebonyi can expect rain starting between March and April.
  • The middle area is likely to see rainfall between April and May.
  • In northern countries such as Sokoto, Katsina, Kano, Jigawa, and Borno, the rain will arrive between early June and July.

Conversely, early rain is predicted in delta, bayelsa, rivers, anambra, and southwest. However, some states such as Plateau, Kaduna, Niger, Taraba, Adamawa, and Kwara may experience delayed onset.

As for the end of the rainy season, stopping is expected to start from October 6 in some parts of Sokoto, Zamfara, and Katsina, moving gradually south until December 17, when the last rain is expected in coastal areas.

Nimet issued a warning about severe dry spells in some parts of the State of Oyo, where cities such as Saki, Iseyin, Ogbomosho, and Kajola may experience up to 15 consecutive days in a row even after the rain.

Other regions, including Ekiti, Osun, Ondo, Ogun, Ebonyi, Anambra, IMO, Abia, and Cross River, may face moderate dry spells with the same duration.

In the north, severe dry spells up to 21 days are projected between June and August, right in the middle of the planting season, a threat to agricultural productivity.

Nimet has suggested government, farmers, and the general public to prepare proactively, emphasizing the need for adaptive agricultural techniques, city planning resilience, and early warning systems to reduce the likelihood of disasters caused by the climate.

The agency projection not only provides weather views but an invitation to act. With more than 80% of Nigerian agriculture that is fed rain, shift in rainfall patterns can significantly affect food security, public health, and economic stability.
