I do a lot of international travel but ever since I heard that Charleston South Carolina was the #1 place to visit in the U.S I had to put it on my bucket list. When to Travel I went in February and the weather was very similar to Georgia weather it was cool on some days and warmer on others and it did rain once at night . I would recommend to carry a light jacket. I spoke with some of the locals and they confirmed that coming between February and March is a perfect period
