One thing you’ll never hear me complain about is the Savannah area weather. Winter temperatures rise and fall and some of the cooler days are usually quite welcomed. Just bring plenty of socks along to wear with your sandals. With all kidding aside, you should find the temperatures pleasant for most of the year with the exception of July and August which can host 90 degrees everyday with very high humidity.
