Pockets of rainfall witnessed in the month of February are indications of gradual return of the rainfall especially in the southern and central parts of the country, while normal condition dominated the rest of the country particularly the North. Also worth mentioning, is the moderate to severe wetness over Abuja and Lokoja in the central part of the country.
Normal condition prevailed over a significant portion of the country particularly in the North with attendant dusty and hazy weather condition due to the dominant dry winds. However, almost the entire southern part of the country, except Oshogbo, experienced mild to extreme wetness following above normal rainfall amount recorded by some of the stations during the period under review.
Dry and slightly hazy weather conditions prevailed over the entire country particularly in the Northern part following cessation of rainfall during the period under consideration. However, Ijebu-Ode, Warri, parts of Benin, Ondo, Oshogbo, Ibadan and Ikeja experienced mild to moderate wetness, which apparently was due to coastal effects, although few other coastal areas like Port Harcourt recorded mildly dry condition.
Dominance of normal condition over the country clearly indicates the end of the rainy season as well as setting in of the dry season with recent hazy conditions over most Central and Northern states. Though, certain degree of wetness (severe to mild) was recorded particularly in the South, lessons must be learnt from the devastating flood episodes of this year in order to prevent future occurrences.
The month of October witnessed low wetter than normal conditions compared to September which is a clear indication of end of rainy season over the country. Though normal condition prevailed, appreciable degree of wetness especially over Sokoto axis of the extreme North was recorded. Notable as well is mild to moderately wetness recorded over places like Zaria, Kaduna, Minna Lokoja, Makurdi, Ibi in the North and few places in the South like Calabar and parts of Enugu, Benin and Oshogbo.
As expected, the month of September was wetter than August. While normal rainfall condition prevailed over greater parts of the country particularly in the North-western area, mild to moderate wet conditions were observed over places like Minna, Kaduna, Zaria, Nguru, Maiduguri and Yola extending to Makurdi North and Oshogbo, Benin, Enugu, Owerri, Calabar and parts of Port Harcourt in the South. Bauchi experienced extreme wetness. Pockets of mild to moderate dryness were also observed at Gusau, Potiskum, Lokoja, Warri and Ikom.
The month of August in contrast to July shows a widespread of normal rainfall condition in most parts of the country even though mild to extreme wetter than normal condition was observed over places like Minna, Kaduna, Zaria, Kano, Nguru and parts of Bauchi, Potiskum, Maiduguri and Katsina respectively while mild to dry conditions was the case over Sokoto, Gusau, Yelwa, Ibi, Bauchi, Warri, Benin and Lagos. Notable is the severe to extreme dry conditition recorded over Jos compared to the extreme wetter than normal condition recorded in June and July respectively.
The month of July is significantly wetter than June, as the entire country dwells under normal to extreme wetter conditions. The North down to the central parts of the country in this regard was of great interest in terms of degree of wetness particularly over Bauchi, Jos, Makurdi, Ibi and parts of Maiduguri compared to the South which may be due to the effect of the little dry season which occurred in the third decade of July.
Significant wetter condition experienced during the month of June in almost every part of the country is a clear indication of establishment of rainfall season particularly over the Northern region. Noticeable is the moderate to extreme wetness over Kano, Nguru and parts of Katsina in the North with Benin, Ikom, Warri and Ikeja in the South. Meanwhile, stations like Yelwa and others in the Northwestern flank of the country were characterized with mild to severe dryness.
Widespread of wetter than normal to normal condition experienced during the month of May in almost every part of the country is an indication of rainfall season particularly over the Northern region. Noticeable is the severe to extreme wetness over Jos and parts of Bauchi, Kaduna and Zaria in the North with only Benin in the South. Nonetheless, Lagos and Ikeja stations in the South experienced mild dryness during the month under review.
