Climate change has become one of the most significant challenges for sustainable development. A thorough understanding of the patterns of rainfall in this dynamic environment will aid in making better decisions and strengthening communities' capacity to withstand extreme weather occurrences. Accurately predicting precipitation trends is crucial in a country’s future economic development. Therefore, analysis of trends at the local and regional levels is far more pertinent for specific development and adaptation plans to mitigate the effects of climate change. In this study annual as well as seasonal rainfall trend of Anakapalle district was analysed for the period 1952-2020. Rainfall at RARS, Anakapalle from 1952-2020 exhibited an ascending trend as the value of Mann- Kendall’s test and the magnitude of Sen’s slope estimator were both positive and were found to be 0.007 and 0.245, respectively. The findings revealed an upward tendency for the months of February, March, April, May, August, and September, and a downward trend for the months of January, June, July, October, and December. The rainfall trend during the monsoon period (South West and North East monsoon period) showed decreasing trend while the pre monsoon period exhibited a positive trend. Overall Rainfall trends indicate that distinct climate change has occurred during the last 69 years.

Mann-Kendall test, Monsoon period, Rainfall, Sen’s Slope factor, Trend analysis

The annual and pre monsoon (March-May) rainfall of Anakapalle for 69 years is in increasing trend, where as monsoon rainfall (both South West & North East) is in decreasing trend. Thus trend analysis is highly useful in understanding the monsoon pattern of a district and for its effective use in crop planning in future and for decision making for policy makers.
