The presence of escarpment plays an important role in the distribution of rainfall. Its role was studied and was put together in this paper. Various parameter were studied and they included: amount of rainfall, elevation, latitude and the distance from the sea. In this research, frequency analysis was performed on the parameters and the log-pearson type III was considered the most suitable distribution method. Also, principal component analysis was used to determine that two components best estimates the variables with close correlation to be rainfall, elevation, latitude and distance from the sea as component 1 and distance to nearest neighbour and longitude as component 2. With regional coefficient of variation of 22%, the area has low variability indicative of high rainfall values with good consistency. Annual average rainfall of South Eastern Nigeria is at 1744mm with bi-modal double peaks in July and September as in most parts of Southern Nigeria. From the determination of the difference in mean, it is again obvious that areas close to Udi escarpment have mean below or slightly above mean, hence affecting rainfall.
