The best time to visit Georgia (especially when not visiting the mountains) is in the months of May, June, and September. You will avoid the heat of summer and not get hit with the brunt of the winter, which can get very snowy. If you are coming to ski, which is one of the top things to do in Georgia country, you can go pretty much any time after November and be guaranteed some good runs. Hiking, though you want to stay cool, is really best to wait until the slush has dried and the earth is not so wet. June and September are the perfect times for hiking in the most beautiful natural places to visit in Georgia. However, there is really no wrong time to visit Georgia. We visited in early March and still had the time of our lives.
