The location of Akwa Ibom just north of the Equator and within the humid tropics and its proximity to the sea makes the state generally humid. On the basis of its geographical location the climate of Akwa Ibom State can be described as a tropical rainy type which experiences abundant rainfall with very high temperature.
The mean annual temperature of the state lies between 26°C and 29°C and average sunshine cumulates to 1,450 hours per year, while mean annual rainfall ranges from 2.000mm to 3.000 mm, depending on the area. Naturally, maximum humidity is recorded in July while the minimum occurs in January. Thick cloud cumulonimbus type is commonly experienced in the months of March to November. Evaporation is high with annual values that range from 1500 mm to 1800 mm. As with every Nigerian coastal area, the state experiences two main seasons, the wet and the dry seasons.
The wet or rainy season lasts between eight to nine months starting from mid- march till the end of November. The dry season has a short duration of between the last week of November or early December and lasts till early march. Despite the seasonal variations, by the nature and location of the state along the coast which exposes it to hot maritime air mass, rainfall is expected every month of the year (Usoro, 2010; Inyang, 2000).
