Hence, the rainfall data of the past three decades (1991-2020) was analyzed by using non parametric statistical tests i.e Mann-Kendall (MK) test and Sen’s slope estimator for determining the trend and magnitude. The Results of the study revealed that Z test value for annual rainfall was significantly increased with Positive linear trend of Sen’s slope estimator with +12.79 mm increase per year. Among the seasons Southwest monsoon period reported significantly positive trend with Z value of 2.07 and Sen’s slope estimator was +9.227 mm per season. Highest rainfall variability (116.3%) was found in the winter season with negative Z value (-1.559) and decreasing Sen’s estimate of -0.397 mm per season was reported. Mann Kendall test values for monthly rainfall reported that significant increase in the march month with Z value of 2.030 and Sen’s slope estimator was highest during the month of August +3.988 mm per month.
