Abstract: In the recent years the important scientific challenge faced by researchers worldwide is to have a better understanding about climate change at a regional scale. However, for all the regions the changes are unequal and have localized intensity. Therefore it should be quantified at a local scale. Therefore in the current study, an attempt has been made to observe the temporal rainfall variability and trend over a period of 30years (1989-2018) at regional scale for the district Bargarh of Odisha. The detailed trend analysis of rainfall during the period 1989-2018 on seasonal and annual basis was carried out in the current study. The month of June, July, August, September is getting the leading part of the rainfall, the month July is getting highest and September is getting the lowest amount of rainfall. On an average July is getting 360mm and September is getting 202mm of rainfall respectively. The annual rainfall of the location is deviating with a Percentage change in annual and seasonal rainfall was also determined to show the change in trend. Ten year moving coefficient variation (CV) of seasonal rainfall showed a decreasing trend during kharif season and a constant trend during rabi season. The coefficient of variations is 96.9% and 22.2% in rabi and kharif season respectively.
