Precipitation holds immense significance for both the environment and its inhabitants, particularly in the context of agricultural activities, which rely heavily on the availability of rainfall. Accurate estimations of future precipitation levels at specific locations are therefore essential for informed environmental and agricultural decision-making. In this study, time series analysis was employed to assess precipitation patterns in North Central Nigeria. Monthly rainfall data spanning a forty-year period (1981-2020) from four stations in specific North Central Nigerian locations was sourced from the Nigerian Meteorological Agency. Various statistical measurements were applied, including mean, median, maximum, minimum, standard deviation, variance, skewness, kurtosis, and coefficient of variation.The year 2001 witnessed the highest mean annual rainfall, reaching 14662.3mm, while the lowest was recorded in 1983, at 645.7mm.Consequently, the findings indicate an increasing trend in rainfall over the research duration.

Keywords : Precipitation, Time Series, North Central and Nigeria.
