The average high temperature on November 1st in Savannah is 74, and the average low temperature is 52. Atlantic hurricane season runs through the end of the month so it may be dry and sunny, but also may hurricane. Plan accordingly.
Early November weather can vary from quite warm to somewhat chilly in Savannah. Weather permitting, the closest beach is Tybee Island, about 30 minutes from Downtown Savannah. This is also the only beach in the area where alcohol is permitted. Alternatively, Hilton Head Island is an hour drive. Alcohol is not permitted, more resort-type feel and family-friendly.
