Yes, I live on the island mentioned in the article. This place gets insane with tourists during the Summer months, but gets much calmer during September. The weather is also nicer, with the highs averaging in the mid-80s(F). The summer months are generally hot and humid -- this is the deep South after all.
I'll have to defer since you live there, but I'm from South GA and my sisters live on SSI and I'd think September would be hotter than that & October would be nicer (my favorite month in GA overall).
Also, if you happen to live in the Northeast, I recommend a visit to SSI in the early spring to cure that endless winter misery that you get in March & sometimes April.
Fall in general is great. My perception (which I’ve not validated) is October is generally wetter. That may just be from anomolies the last yew years than the actual climate, though.
Just don’t come the weekend of the Georgia-Florida football game in late October. 10,000 (newspaper’s estimate, not mine) Georgia fans flock to the island and get drunk. We’re not at all equipped to handle that many college kids all at once.
Perhaps it was lumping all southerners together and calling them all inbred racists that resulted in a bad time for you. I think a lot of people would like to explore Georgia as a Florida alternative
All the barrier islands are beautiful - Cumberland, SSI, Jekyll, Tybee and they aren't too busy (well, except Saint Simons during the GA/FL weekend which is a blast in and of itself).
