Atlanta woke up sticky and steaming on Monday, June 29, 2026, with clear skies, mid-70s temperatures, and the sun already working overtime on neighborhoods across the metro. By afternoon, highs are expected to climb into the mid to upper 90s, and once you factor in the humidity, it will feel well above 100 degrees for much of the area. If you have to be outside, early morning and evening are your best bets, and midday should be treated like the no-go zone of the day.
Heat Advisory Details
The National Weather Service in Peachtree City has a Heat Advisory in effect from noon to 8 p.m. Monday, June 29, 2026, covering much of metro Atlanta and surrounding counties. Forecasters say the heat index could push past 100 degrees and may spike to 105 to 110 in parts of central and east-central Georgia. Officials are urging people to limit strenuous outdoor work during those hours, drink plenty of fluids, and check on vulnerable relatives and neighbors, especially older adults and infants, according to the National Weather Service in Peachtree City.
Afternoon Hazards And Timing
The most brutal stretch is expected roughly between 11 a.m. and 4 p.m. Northwest winds of 5 to 10 mph, with occasional gusts up to about 20 mph, will not do much to cut the soupy air. Isolated, fast-moving thunderstorms could pop up late in the day across eastern parts of the metro, but for most neighborhoods the main issue will be prolonged, unhealthy heat. We covered how we got to this point in our earlier coverage of the heat build-up.
Where To Cool Down
If you lose power or simply need a break from the heat, some nearby communities have recently opened emergency cooling centers during an outage, with local examples listed by FOX 5 Atlanta. To track down an open cooling spot today, call 311 or check your county's website. Otherwise, keep water handy, avoid heavy exertion during peak heat, check on neighbors who might be at risk, and keep pets indoors where it is cooler.
