At an average elevation of 50 feet above the Savannah River and 18 miles from where river empties into the Atlantic Ocean, Savannah is surrounded by low marshy land. The land closest to the ocean is a temperate rain forest with lots of oak, pine, and magnolia trees. It has a subtropical climate with nearly 70 days of rain each year.
Snow is highly unusual, which makes for a long growing season.
Oh yes, summers often reach 100 degrees.
