Mostly yes, if the weather does not put you off. August in Charleston is Lively on the typical day, and not one of the 31 days in our window is crowded enough to call Busy. Expect around 30 °C by day, with rain on about 19 days. No week of August is meaningfully quieter — the typical day is Lively throughout; pick by day instead. The crush is at the City Market's aisles; the quiet is at South of Broad's residential grid.
In short, a solid middle-ground pick.
