Atlanta lies in the foothills of the Appalachians. Although it is cooler than other parts of central Georgia, its summers are still hot and humid. Those unaccustomed to this kind of climate will be more comfortable in the spring or fall.
Spring is a beautiful time to visit Atlanta—the abundance of flowering trees and shrubs, such as dogwoods and azaleas, turns the city into a fragrant pastel garden. Temperatures are mild, 50-79 F/10-25 C, but travelers should be aware that severe thunderstorms and even tornadoes may occur in the Atlanta area then. Fall weather is more predictable—most days are sunny and warm. Winters are short and mild, but weather can be dreary and the city usually sees at least one ice- or snowstorm each year.
Atlanta's climate yields many varieties of plants and flowers, which may be a nuisance to hay-fever or asthma sufferers. Air pollution can cause respiratory distress as well, especially in the summer. If you suffer in these conditions, avoid going outdoors during late afternoon and early evening. Local news broadcasts track the air-pollution and allergen levels.
