The average weather for Atlanta in October is in the upper 60's to mid 70's range. The weather is pretty warm and dry, so I would pack jeans and t-shirts. I would definitely bring a few jackets too just in case.

Weather in Atlanta is still relatively warm this time of year, with the average temperature being in the low 70s during the day and high 40s at night. Packing a sweater and layering throughout the day is ideal to be prepared for any temperature fluctuations.
