The present research investigation was undertaken to work out the rainfall variability of all districts of Rayalaseema in Andhra Pradesh. The meteorological data of rainfall required for the rainfall variability analysis was collected during 1989-2018 from Central Research Institute for Dryland Agriculture, Hyderabad. The coefficient of variation and standard deviation for monthly and annual rainfall were also computed for all the districts. The normal onset of monsoon over different districts of Rayalaseema is between June to October. Results showed that the annual rainfall is higher at Chittor district followed by Kadapa and Kurnool. The mean annual rainfall is lowest at Ananthpur. When the CV for the annual rainfall or rainfall variability was examined, it was found be the least at Kurnool followed by Chittor and Kadapa. At Ananthpur it was the highest.
