Atlanta woke up Tuesday, July 28, 2026 already sweating, with temperatures hovering near 79°F (26°C) and relative humidity topping 80 percent. It is only getting rougher from here: afternoon highs are expected to reach around 96°F, with the heat index surging well into the 100s by mid-afternoon. Residents are urged to skip strenuous outdoor plans during the peak heat.
Heat Advisory Details
The National Weather Service has issued a Heat Advisory from noon to 8 p.m. on Tuesday, July 28, 2026, warning that heat index values could climb between 105°F and 109°F and urging people to drink plenty of fluids and limit outdoor exertion, according to the National Weather Service. The advisory covers much of the metro area and notes that the combination of high heat and humidity will make heat-related illnesses more likely, especially for older adults, young children, and people who work outside.
Afternoon Heat, Gusts, And Storm Risk
Through the afternoon, expect west winds between 0 and 10 mph, with occasional gusts up to 20 mph that will not do much more than shuffle the hot air around. There is also a slight chance of showers or isolated thunderstorms late tonight between about 11 p.m. and 1 a.m. If storms manage to develop and slide south or east, they could bring localized damaging wind gusts and frequent lightning, so keeping a weather app nearby is a smart move. For most neighborhoods, though, the main story today remains the extreme heat.
Where To Cool Off
The City has opened a temporary cooling center at Selena S. Butler Park, 98 William Holmes Borders Senior Dr NE, operating Monday through Friday from 11 a.m. to 6 p.m., with bottled water available, according to the City of Atlanta. Public libraries, community centers, and many fire stations can also provide a break from the heat. If you are not sure where to go, call ATL311 for help finding a nearby spot.
Plan For The Week
Some relief is on the horizon. By midweek, highs are expected to dip into the low 90s on Wednesday, with drier air moving in Thursday and Friday before rain chances tick up again over the weekend. Saturday and Sunday bring a better shot at showers and thunderstorms, so it is worth having a backup plan for outdoor events. In the meantime, keep an eye on alerts if you need to work or exercise outside, and check on neighbors, pets, and anyone who may be vulnerable during the hottest hours, roughly from noon to 6 p.m.
