This research aimed to investigate the trend of annual average precipitation (mm) in Georgia from 1950 to 2011. It was conducted through analyzing data from the U.S. Historical Climatology Network database. This data included the amount of daily rainfall (mm) between 1950 and 2011 of twenty rain gauge stations in Georgia. The data was summarized and dissected using statistical computing platform R-Studio. The study is important because it provides information about the precipitation behavior over time and is useful to predict future rainfall for Georgia. Moreover, it is apparent that precipitation trends constantly changing due to climate change.
