Atlanta is waking up Sunday, August 30, near 74 degrees under mostly clear skies, with a mostly sunny afternoon ahead. Temperatures will climb to around 90 degrees, setting up a warmer and drier stretch that lasts through the work week.

The latest forecast shifts Atlanta away from Saturday’s stormier setup and toward steadier heat. The National Weather Service has no watches, warnings or advisories posted for the area, while a previous Hoodline forecast highlighted the higher storm risk from Saturday.

Mostly Sunny Sunday, Small Storm Risk

Sunday’s high should reach about 90 degrees with an east wind near 5 mph. Rain chances are around 10% in Atlanta, although an isolated afternoon thunderstorm remains possible in parts of central Georgia.

Sunday night will be mostly clear, with temperatures falling to around 72 degrees and winds staying light from the southeast. For outdoor plans, the bigger concern is building heat rather than a washout.

Heat Takes Over By Midweek

Monday will be hotter, with a high near 92 degrees and heat-index values reaching about 97. Tuesday should be sunny and near 94, while Wednesday and Thursday are forecast to reach around 95 degrees.

Friday also looks close to 95 degrees, with a slight chance of afternoon showers and thunderstorms after 2 p.m. Saturday should remain sunny for much of the day with a high near 94 and a somewhat higher 30% chance of storms after 2 p.m.

Plan Around The Heat

Light winds and sunny skies will make Sunday manageable, but anyone spending extended time outdoors should carry water, take breaks in shade or air conditioning, and avoid the hottest part of the afternoon when possible. The weather service expects triple-digit heat indexes in parts of Georgia south of Interstate 85 as the week progresses.

Overnight lows rising into the mid-70s will offer limited relief, especially for people without reliable air conditioning. Check on older neighbors and anyone especially vulnerable to heat, and keep pets and children from lingering in hot cars or direct sun.
