When to Go It's not the heat, as they say, it's the humidity. The summer in Atlanta has plenty of both, with temperatures typically ranging from 80 degrees to 95 degrees (Fahrenheit) or higher. The nights don't cool off much. In March and April, Atlanta's temperatures are elysian, and the city is awash in the blooms of dogwoods, cherry trees, and azaleas. September and October often bring Indian summers, and the temperate weather can linger as late as mid-November. The short winter is usually fairly moderate. From spring through fall, various neighborhoods host colorful artists markets and street fairs, including the National Black Arts Festival ( 404-730-7315 ), a biennial week-long celebration of African-American contributions in all aspects of the arts. Music Midtown, held the first weekend in May, is a two-day rock celebration featuring multiple stages and dozens of national acts. And the Atlanta Jazz Festival, held in late May, is the largest free jazz festival in the country, featuring eight days of outdoor concerts in Piedmont Park, with national and local acts, a market exhibiting artwork, and food vendors. What to Take The summer is hot and muggy during the day, so visitors will want to wear as little clothing as possible. The nights are imperceptibly cooler. One important note, though: All indoor areas are air-conditioned, and office buildings in particular like to keep their thermostats set to sub-Arctic temperatures. In November through early March, a light winter coat is recommended. In the spring and fall, bring light clothing and some layers. The weather tends to be warm, but brief cold snaps are not uncommon. In the spring, fall, and winter, bring a raincoat. And at all times of year, take an umbrella, because the humidity frequently turns to rain. Time Zone Atlanta is in the Eastern time zone (Greenwich Mean Time minus five hours). From early April through late October, Georgia switches to daylight-saving time.
