This article focuses on the studying and analyzing the rainfall variability at Elkhuwei area. The data for rainfall variability was collected from Meteorological authority-Khartoum for the last four decades. The mean, standard deviation and coefficient of variation were used to calculate the rainfall variability on long-term annual basis. The results showed that the rainfall is highly fluctuated and varied over both space and time. The coefficient of variation for this period is equal to 0.33 and the standard deviation is equal to 114. Two positive and four negative anomalies were found during the period 1970-2010.
