During the month under review, most parts of the country were under normal condition except Yelwa, Ilorin, Makrudi and Ibi in the North with only Port Harcourt in the South that was mildly wet. Also, Yola, Potiskum, parts of Maiduguri and Bauchi in the North while Warri and Calabar in the South were under mild to moderately dry condition compared to normal. The 1-month Standardized Precipitation Index (SPI) analysis over the country reveals most parts of the country to be under normal condition. However, notable is the mild wetness over Yelwa, Ilorin, Makrudi and Ibi in the North with parts of Ibadan and Port Harcourt in the South while places like Potiskum, Yola, parts of Maiduguri and Bauchi in the North with Warri and Calabar in the South experienced dryness ranging between mild and severe (Fig.1). In the 3-month SPI analysis, normal condition also prevailed except for some places like Potiskum, Yola, Bauchi, Jos Minna, Lokoja, Enugu and Owerri that witnessed mild to severe dryness. Meanwhile, places like Yelwa, Makurdi, Ibi, Ikeja and parts of Port Harcourt and Calabar experienced mild wet condition. This is due to cumulative effect of previous three months of rainfall amount (Fig. 2).
