A statistical analysis of data on number of days with hail (annual and for period from April to October) in 43 locations of Georgia in 2006-2021 are presented. In particular, the following results are obtained. The max average annual number of days with hail in Akhaltsikhe is observed (3.4). The max annual number of days with hail in Mirveti is observed (16). The max average number of days with hail in warm period in Akhaltsikhe also is observed (3.3). The max number of days with hail in warm period in Khashuri is observed (9). The climate change influence on the number of days with hail during the warm period has been studied. Comparison of the number of days with hail for 30 meteorological stations in 2006-2021 and 1941-1990 showed that in the second period of time, compared to the first period, the number of days with hail at the 18 stations decreased, at the 10 stations - did not change, and increased at only one station (Keda). The data of this work will be used to compile a Natural Hazards Catalog in Georgia.
