Severe weather in Atlanta, Georgia can arrive fast, change quickly, and affect everything from your commute on the Downtown Connector to flights at Hartsfield–Jackson. Whether you live in the city, are new to the area, or are planning a visit, understanding Atlanta’s severe weather patterns helps you make safer, smarter decisions year-round.
Atlanta’s weather is shaped by its humid subtropical climate, its location in the Southeast U.S., and its slightly higher elevation compared to surrounding areas. The city doesn’t see the same level of extreme weather as some coastal or Plains regions, but it still faces a mix of serious hazards:
