Despite Georgians’ constant umbrella use of late, most of September 2015 was actually drier than normal.
Most areas of Georgia reported less-than-normal precipitation, except those in the far southeast of the state. The precipitation was scarce early in September, but rain was more plentiful during the last week, which resulted in a reduction in drought.
Those early-September dry conditions increased pest pressure on some crops, but allowed for the reaping of corn and other crops. Increased rain at the end of the month reduced drought levels, but caused problems for farmers who wanted to harvest peanuts and other crops. The rain improved forage conditions for livestock producers.

The lowest monthly precipitation total was recorded in Columbus, Georgia, as 1.92 inches, 1.14 inches below normal. Atlanta received 3.93 inches of precipitation, 0.54 inches below normal; Athens, Georgia, received 3.48 inches, 0.46-inch below normal; Macon, Georgia, received 2.09 inches, 1.50 inches below normal; Savannah, Georgia, received 2.89 inches, 1.69 inches below normal; Augusta, Georgia, received 4.05 inches, 0.83-inch above normal; Alma, Georgia, received 5.02 inches, 1.38 inches above normal; Albany, Georgia, received 3.87 inches, 0.43-inch above normal; Rome, Georgia, received 3.03 inches, 0.38-inch below normal; and Valdosta, Georgia, received 3.21 inches, 1.43 inches below normal.
