Atlanta has four distinct seasons, but the climate is generally mild most of the year. Spring arrives early in Georgia, with short sleeves and sunglasses coming out as soon as March. A fit of blossoms and new foliage erupts in April and May, along with some of the city’s best annual events. The Atlanta Dogwood Festival is the unofficial start of spring, while the Inman Park Festival features one of the most bizarre parades of the year. Expect big crowds at both events.
July and August are perhaps the two least desirable months to visit, unless you like hot, sticky weather. Average highs hover around 89 degrees, and the humidity is infamous, making outdoor activities uncomfortable and leading to longer-than-average lines for indoor attractions. Summer’s warmth lingers well into autumn, though breezy days in October, with highs around 73 and lows in the 50s, are relaxed and pleasant.
Newcomers might be surprised to find temperatures that dip below freezing in December or January, but cold snaps don’t tend to stick. Barring a random extreme winter weather event, Atlanta usually sees snowfall only once or twice a year.
