Data for the period 1981-2017 were collected on yearly and monthly basis to calculate annual and seasonal rainfall trend and variation. Mann-Kendall (MK) test was used together with the Sen's Slope Estimator for the determination of trend and slope magnitude. South West (SW) monsoon has the highest share in the annual rainfall. Annual rainfall followed the same trend of SW monsoon, which is increasing over the period. North East (NE) monsoon and winter rainfall indicated decreasing trend over the years, whereas summer rainfall exhibited a significant increase.
